To the inexperienced that could very costly.

Static damage is the most common cause of computer hardware failure
and not covered under warrenty and is easy to tell.

Our friend doesn't seemed to be all that experienced pointing out no thermal paste and doesn't know what a multimeter is or how to use it.

It's one thing if your talking to a peer and quite another to someone with
less experience who might be trying to wing it on their own.

Anywho it is probably a moot point. We'll never know if he fryed something.

I hope him the best of luck as I'm sure you all do.

That is why I emphasized that it is good prevention. Or maybe did I not emphasize that enough?

By the way, it is easy to return static killed parts. It is hard for them to tell too. They just think a transistor failed in the silicon. Replaced under warranty.

Yep -it is crazy. I did a double take when I read that, and it explained my circuit breaker popping - and the need to reset it. I thought it had a short at first.

This is the PSU in question:
http://www.silverstonetek.com/produc...no=st60f&area=

It is on page 1 of the manual - http://www.silverstonetek.com/downloads/st60fmanual.pdf

Looks like I was wrong! Only 50 Amps! (only) :D

PS. A thought just occured to me - the inrush voltage of the video board is going to be high as well - the reason the protection of the PSU kicks in and the reason for the lack of power to the whole system for it.

Just thought of something else. Make absolutely sure that the MB and CPU power connectors are firmly placed in their sockets. If they are even slightly misaligned the connection won't be complete.

Take it to a computer repair place and have them look at it. It's better to pay a diagnostic price than have to rebuy expensive hardware because you burned it.

Well, I don't agree with this idea at least. This is no way to learn.

Expensive mistakes suck unless you can afford it.

They still suck just as bad even when you can afford it. I don't care if I rack in 10 digits a year, I will still get ticked at $100 mistake. :D

Anyway, to learn is actually more important that that $100. Eventually, you become an expert, and it can't make you many many times over that amount for your learned services. Look at the problem as an asset, instead of a liability is all I am saying since I don't think he will screw his system up, but he will definitely learn from the ordeal.

Sometimes the best thing to do is step back take a breather and then go back with a fresh out look and take it all apart and start over with the new advice and tips and VERY carefully put it back together double checking everything. Then cross your fingers and push the on button.:)

I read your posts very closely and you had help building his last rig.
I would suggest you do so again. It will be alot cheaper and a learning experience.

If you want experience take your old rig apart and put it back together
yourself with NO help and see if it works. If it does then youv'e gained knowledge and skills at minimul cost risk.

Again I wish you success :up:

Have you tried the paperclip PSU test?


*** MAKE SURE THE POWER SUPPLY IS UNPLUGGED FIRST *** Simply Jumper Pin 14 ( which is the green wire) to any of the ground pins which are 3,5,7,13,15,16,17 ( all which have a black wire). I use a paperclip to do so, just stick the paperclip into the connector like you would be pluging it into the motherboard.

In my shop we had an LED connected to two wires via this method. Not only did the fan turn on, but the light did also.

Laffertytig 10-11-07 03:18 AM

firstly, the cpu already has thermal paste so no worries there. still no joy with the power though.
heres what ive tried

pc case to MOBO wiring - on the case i have a "power sw" lead which has 2 holes. a "pow led -" and a "power lead +" both single hole. on the MOBO ive tryed pluggin these into the relevant pins to no avail. i reckon ive tried everythin with these wires
on the old asrock MOBO there was only 1 "power switch" lead which plugged into the "power button" socket which was a lot simpler.
i managed to wire up the old equipment in an older case no prob but no so with this new stuff.


someone said to try it without the vid card but no joy there either. the PSU has 4 cables and all are defo pluggle in the right place.
the tower is around 3 years old could the wiring in the actual case be the problem?

THE_MASK 10-11-07 05:47 AM

Maybe take everything apart and start over . You have turned the on/off button to on at the back of the tower havnt you .

Laffertytig 10-11-07 06:00 AM

haha yeah mate i aint no expert but i do know how to switch on a pc

bradclark1 10-11-07 08:41 AM

sober is President of the slow learners association inc. :D

Laffertytig 10-11-07 09:14 AM

i congragulate him on his post:) im led to believe the problem is that my PSU is of the cheap variety. whats power wattage would people recommend for my system?

the graphics card box recommends 750w or 400 minimum but others have said thats overkill

FIREWALL 10-11-07 12:17 PM

That vid card will want power and lots of it.

I myself use an ULTRA X Connect 2. 550 W gets rid of all that ugly wireing. Check it out. $100.00

You didn't learn this in the US Navy old friend ... short cuts are not allowed, uh?

Have you ever had the pleasure of touching a three foot tall capacitor for the BQS 4 to discharge it for maintence?

Don't forget to use the proper methods are they will carry your chared body out of there.

I guess this THREAD is DEAD.:rotfl:
