Hmm if it was hardware problem from the beginning the problem would not disappear for the whole year
.
My firewall is good enough.
I noticed a sudden spike on CPU load on Friday and right after that a command prompt like windows was run and two minutes after that the PC just reboot.
The symptoms are the following:
Random restarts
Blue screen of death or BSOD after random restart
CPU spiking full load under no particular reason several times and continued that way until restart
BIOS hang
BIOS failed to load(black screen) after random restart.
Power turning off when BIOS loading happened once today
Most often when just starting the PC for the first time in the early morning or a few hours after that.
Games now run at half performance that it used to rendering them unplayable, other than that it's okay.
Shutting down once today, then beeping sound, internet kept failing to connect until one or two hour later.
Sounds in game now crackling and only sounds in game that's crackling
Windows failing to load a few times
Quite a lot of times Vista would load much longer than usual and control would be lost until network icon appears to be connected(online)
Ran memory diagnostics and memory was reported to be fine
Benchmarking Vista didn't change the Vista index experience.
Ran AV everything checked out no malware or virus reported though I know there's a very high probability of a malware that CIS unable to detect since it would sometimes and often enough cause the screen to switch to desktop even when a full screen game was running. My suspicion grew stronger after a friend who connected his usb suffered the exact symptom on his Windows 7 laptop that the screen suddenly switching to desktop as if a program just started itself. If it spread then it's definitely a virus or a malware.
Protected with CIS all the time
Ran registry cleaner regularly
Umm I wasn't planning to get myself a new rig at least until next year this could ruin my plan.
My suspicion s either CPU, PSU or GPU failing or worst PSU failing that's already damaging GPU.
I'm hoping it's just the CPU which is failing.
That or hacker attack.
Or hacker attack that damaged the PC.
