System Problem -- Please help

[agent47]

hi everyone
i have a pc that i asembled about an yr. ago with the following config:

Asus M4A87TD USB3
AMD Phenom X6 1050T
MSi n480GTX GPU
Coolermaster GX650 psu
Gskill trident 2x2GB 1600 Hz
WD Caviar balck 1tb + caviar green 1tb

for the first 6 months there was no prob. after that the d"display driver stopped responding" errors started but were not that frequent.
then it became way to much n since my motherboard has been replaced twice. now, I think my psu is done for as the core unlock light that glows whenever the power is connected too doesn't glow and the system has stopped running totally.
also a lot of time my system becomes normal when the display driver STOPS responding while other times it just gets stuck...
the display does out... no restarts n no recovery either.
at first i though it was just coincidence but my system has started having lot of problems recently.
please i need some serious help....
wtf is wrong.. is it the config....

First check for any viruses then Please post ur OS what Display Driver version ur using

Update ur Drivers Display as well as MB and BIOS if possible perform a clean install of the OS & see if the prob persists

Also run these & get back

FurMark: VGA Stress Test, Graphics Card and GPU Stability Test, Burn-in Test, OpenGL Benchmark and GPU Temperature | oZone3D.Net

Measure Computer Performance | wPrime Multithreaded Benchmark

BTW i see no prob in ur config

Try properly refiting all cables, Ram.
Do a scan using this Antivirus=

The Windows registry could become
corrupted by a virus, Trojan horse or
malware. Any of these nasty programs
can be downloaded without realizing
it. They can cause havoc on a machine,
including freezes. The registry can also become corrupt if the computer gets
hung up and crashes. In some cases,
software may have been sending a
message to the registry that became
garbled and was recorded improperly.
That bad command will remain in your registry until you clean it with a good registry cleaner.
