Hello, can you help please ?, I have build my new computer with the MARS FOXCONN Motherboard, but when i turn on the pc , after a few seconds i hear the normal single short beep from the motherboard , after that in the black screen appeared some information about the video card 8800GT 512Mb etc , after in the red screen appeared the two greek MARS Motherboard black warriors and a sentence " PRESS TAB TO SHOW POST SCREEN , DEL TO ENTER SET UP , but the PC immediately (at once) turn off automatically ,after two seconds the PC turn on automatically and repeat exact the same process (as before) again and again and again and again ,there is a blue small light next the motherboard connections of the front panel ,and a red smal light close to the extreme right ram memory slot .please help , my system is PSU 650WATTS seasonic , intel core 2 duo 3GHz E8400 6Mb cache, sata Hard disk 320GB HITACHI , 3GB RAM 800, nVidia Sparkle 8800GT 512Mb fanless cool-pipe, sata opticalDrive , Coolermaster CM690case ,thank you

I'm unfamiliar with THAT particular motherboard, but don't panic. It looks like things might not be that bad.

Good news:
Your CPU, memory, and CGA video are working because you can see the bios post. Since this is the 1st time you started the computer, the bios wants you to at lease VISIT the bios settings so you can set the clock and visit all the screens to see all the components of your computer are working. I suspect the reboot is a timeout because you are not pressing TAB (this is unusual- you are sure it's not DEL?) soon enough. Go ahead and press the SETUP button, set the clock, visit the screens (don't touch anything you do not understand) and with the OS installation disk in your CD drive, SAVE and EXIT the bios. Your computer should detect the OS disk in the drive and start installing it.

If all the components of your computer are working, things should go smoothly after that.

The two LED's you are referring to only indicate its getting power. Could be almost anything causing it to not post, but hopefully you tried the simplest things allready like reseating your ram.

Try hitting the tab before it resets so you can get into the bios. This will be a little more indicative of where to look for the problem.

As another stupid thought, check that your cpu cooler is plugged into the proper header. If you missed by an inch you'd be in the north bridge power socket, and this board has a default setup in bios to read the rpm of the cpu fan and not to boot if its not receiving signal.

Probably you have to check all connections .. I have build dozens of computers and it has happened to me many times that ;

floppy / harddisc cable was not properly connected
graphic/sound card was not firmly in its slot
memory modules / cpu

Did you forget that your graphic card needs to be connected with a power cable? I think my brother also didnt get past the post screen because of that.

Another very nasty problem that happened to me once is that the mainboard was in contact with the case. I had forgotten to use plastic washers which produced some sort of short circuit. The computer wouldn't POST but it all went away once I had installed the mboard a second time with the washers.

Keep checking and you will finally get it running .. in most cases the hardware doesnt take damage, fortunately, but care is necessary.

:D YES , this must be the reason , I install inside the case Coolermaster CM690 three exhaust fans (140/120mm) and three intake fans (140/120mm ) , and I dont install any fan in the Coolermaster Hyper 212 CPU cooler , thinking that the airflow was already enough with this Six 120/140mm fans , this is the reason ,thank you very very very much :D

Usually if the CPU fan connector is plugged into the wrong place or not at all, the MB will issue a series of beeps in addition to the startup single beep.

Unfortunatly , the CPU ( connected/non connected) fan was not the problem ,I connect two differents fans ( 3 and 4 pins) to the CPU fan MOBO connector and the PC turn off again and again after the message ...."press tab to show post screen, delete to enter setup

the extra power connector to the video card is connected properly , all three RAMs are properly seated

Double check to see if the heat sink fan is properly seated on the cpu.

Secondly check to see if the auxillary power to the G PU cooling fan is connected.

You do have the main power supply connector and the secondary power connector hooked up right?

Most motherboards will POST with the main connector, but due to insufficient power to the CPU will shutdown as soon as it tries to bootstrap the CPU.

Hello,
I ran into that problem myself before, you have something wired wrong. You might have to go through everything one by one to make sure you didnt miswire. I would suggest you go through by unplugging and plugging everything back in place. You might also have to make a change in the bios, maybe, but odds its not really the bios. Worst case scenario follow the instructions n the manual from wiring to bios config.

How goes it tonschk? Any luck? Try pressing that delete key to enter CMOS settings and to to the system monitoring page where you can see motherboard and CPU temperatures. Your clue might be there. If the CPU is overheating, for instance, your thermal paste might not working right due to bubbles or voids and heat is not being transmitted to the heat sink. I've seen that several times with problems identical to yours.

Especially if that shows normal temps, unplug all expansion cards that are not necessary to start your computer and all but one stick of memory. You want to boot up in the simplest possible configuration. If that is successful, try peripherals one at a time until you find the culprit. If it doesn't boot, remove the memory stick and replace it with the other. If your problem is a defective component this could be tough.

I would suggest that you ONLY connect was is needed to POST.
That means, MB, RAM(min amount), CPU, Graphics card.

No HD, No floppy.

That will simpify things for you

Hello , thank you all for the help , I removed the video card nVidia Sparkle 8800GT 512Mb Fanless heatpipe and after that I turn on the PC , the PC make a little bit "longer" single BEEP ,but the screen is fully continuosly black because this MARS Motherboard dont have the integrated video card , but the PC dont turn off automatically any more ,the PC is running continuosly "ON" , to turn off the PC,I must press the switch (on/off) just once , if I add the video card ,the computer start to turn off automatically just one second after this sentence is on the screen..... "PRESS TAB TO SHOW POST SCREEN , DEL TO ENTER SET UP"

1)...I cannot access to change the BIOS even if I press continuosly the TAB or DEL ,when the video card is installed the PC turn off automatically just one second after the sentence "PRESS TAB TO SHOW POST SCREEN , DEL TO ENTER SET UP " appeared on the screen

2)...the RAM is seated properly ( many times already checked)

3)....the extra power cable connector for the video card was properly seated ( before I removed the video card )

4) .....the extra power cable connector (8 pins) for the CPU is properly connected in addition to the 24 pins main connector

5)......This motherboard have nine holes that are upon nine brass standoffs ,properly screwed with only nine screws ,I dont think we need to add plastic whashers between the screws and the MOBO ,because somehow the nine screws must have metallic contact with the MOBO ( I think this is the correct way)

6)....I think the CPU cooler is properly installed because when I removed the video card the PC is running continuosly ( but show only black screen )

7).....I only connected to the MOBO one hard disk ,the optical DVD player , THREE RAMs , CPU cooler , and the video card . NO floppy ,NO sound card

thank you very much for your help

OK, I see possible faults here:

1) Graphics card dead/faulty
2) Powersupply insufficient or faulty.
3) MB dont work with 3 RAM - remove 2
4) Have you connected ALL the nesesary power connectors from the PSU to the MB (Check your manual)

I think either one of the above would create the problems you have.

Can you test the GF card in another machine/Do you have another GF card you can try?

Got this from my friend:
1) Only connect: MB, CPU+fan+Video, 1 RAM.
2) Remove all external connections exept keyboard
3) Remove all connectors from MB to leds, buttons infront
4) Remove powerconnections from powersupply to MB
5) Try and start the PC using the MB connectors (Will not start, but to reset all components on the MB)
6) Move the reset jumper on MB to reset BIOS
7) Remove battery for 10 min - then put it back.
8) Move the reset BIOS jumper back
9) Reconnect power to MB
10) Try and boot

Hows that?

Ill repeat also

Make certain the cpu heat sink is properly seated on the cpu !

Ive had to trouble shoot a very flakey machine that acted exactly as you describe and it turned out the heat sink was not precisly seated on the cpu. The cpu quickly overheated and shut the system down. Sometimes in seconds sometimes a little bit longer.

It was very hard to figure out as all other connections were in order.

02-05-08, 04:52 PM
Isn't there a "default" setting for the BIOS...If so set it to that..I believe you have to have washers on the MD standoffs..Do you know how to clear the CMOS??.Either there is a JUMPER to do it or take the battery out..Your MB book should tell you how to do it..Clear the CMOS and try it again.....

Hello,thank you for the help, I will change the thermal paste of the CPU to another maker,the thermal paste I apply to the CPU cooler was a thermalright almost white colour , now I will apply the one that comes with the CPU cooler i have installed ( coolermaster Hyper 212 " who knows may be

Motherboards no longer (and haven't for a couple of years) need washers, as they actually use the screws and brass standoffs for ground. That's why you see bare metal where the screw seats. Putting washers in there risks a bad ground and a fried board. Be very careful about advice.

Yes ,I know ,around each of the holes of the Motherboard where the head of the screws seats is a small bare metallic area to touch the metal of the screw and ground the motherboard ,I saw that in a book ,I think is correct

This was new to me, but recently I purchased a Asus-P5E Motherboard. It's given me no end of problems and I don't advise buying one :p But....

Believe it or not, the mobo did not know the correct voltage setting for the CPU. I had to manually enter it, it was running half a volt under what it should. Needless to say, the machine was incredibly unstable.

I realise this may not pertain to your problem, but other people need to know. It's the first mobo I have ever seen like this.

Hello , I installed the video card nVidia 7300LE in the new machine , and with this old video card was possible to install the operating system XP Home edition , have done the partition of the disk , but if I install again the 8800GT , the PC have the same problem again , immediately turn off after the sentence PRESS TAB TO SHOW POST SCREEN , DEL TO ENTER SET UP

02-06-08, 01:02 AM
ok so if it works with another video card, that tells us the mobo itself seems to be ok.... in my mind that brings it down to the 8800GT.... its possible there is just a manufacturer defect in the card. i would contact the card's manufacturer and see what they say, you may need to send it back and get another one..... ive noticed from friends that the entire 8800 series seems to be filled with issues, so you may have just gotten unlucky..

Thermalpaste should be applied with a very thin layer. Use a creditcard or something thin to apply it. It should be thin as in almost transparant.

Did you connect the moleconnector to you 8800GT?

The grakka might be perfectly fine.

I had a similar problem with a similar card. After a phone call to EVGA, I discovered that some Powersupplies with multiple 12V rails print inaccurate amperage ratings on their boxes. That or the Amps don't multiply perfectly as you'd assume they would. (eg. 2x18A = 25-30A, not 36A)

I bought a SINGLE 12V RAIL powersupply @ 41A and it solved my "similar" auto-reboot problem.

I will never buy anything but a dedicated 12V rail powersupply ever again.

MONSTEROUS single 12V rail @ 41A

http://www.newegg.com/Product/Product.aspx?Item=N82E16817139004

my previous PSU had (3) +12V rails @ 18A and while that appeared to be enough on paper... my machine powered off randomly from time to time. No power-offs any more -- weeks of solid testing.

EVGA techie told me cheaper PSU's with wimpy 12V rail(s) can "hiccup" and the motherboard cuts off quickly to avoid damage.

negative. some mobos have a button (usually RED) called reset_cmos.

just go ahead and pull the CMOS battery out and wait 30 minutes. It's the easiest way to reset the CMOS.

BE VERY CAREFUL in avoiding static shock when handling the CMOS battery. It's usually near things that dont handle static discharge well.

1. avoid carpet
2. ground yourself by touching the computer's powersupply
3. keep your cat out of your computer case (fluffy or otherwise)

The graphics card does not draw much power at that point in the boot - certanly not more than the 7700 card, so if the 7700 works the 8800 should too.

Hi , I think part of my problem was because i installed a CPU cooler Coolermaster HYPER 212 , the four screws of this cooler (used to attach it self to the CPU E8400 ),have limited thread for the nuts , in other words the thread in the screws is not along all the way along the screw , ( the thread reach only half of the screw) when I was changing the thermal paste to put another paste with 88% of silver ,and realized that even if I turn properly the nut with a wrench , each of the four nuts reach the end of the thread in the screw , without having the possibility to pull enough properly the CPU cooler against the PROCESSOR (CPU), therefore my CPU was touching yes the CPU cooler ,but was not much pressure againg each other , I add a couple of metal washers in each of the four screw and now the situation is better ,if you have the standard cpu intel cooler , you cannot have this problem
