Hi there,

I tried to fix this issue i have with my computer for the past year, it seemed to be overheating, but now, i beleive it turned into a hardware issue. Only problem is, i want to be sure which component is failing before i start randomly buying all the components all over.
My build was used for less than 2 years since 2010, around 2011, the random restarting began happening, but mostly when i play high end games, and the room temperature is fairly hot.

there was a point where my CPU temperatures reached around 70 to 80 Celsius. but that was fixed about a week ago with a new Cooling tower - Tpc 812.
The Random restarts could be becouse of CPU being damaged from overheating, or possibly the power supply being inadequate which i ruled out.


Please help, I dont want to begin another shopping spree, on trial error grounds with my hardware.
- im not a professional when it comes to computers either, i need your comments, suggestions and expertise desperately.

Thank you

in Detail:

When playing high end games, such as HL2 Garrys mod on high graphics, Xcom, or any other game, my Pc would run for about half an hour untill finally, it get to a point where the sound immediately freezes and glitches, the screen turns black, and the pc becomes unresponsive.
Kyboard doesnt work, the CD drive works.

Today this issue has become more clear, when now i attempt to play these games, and only 5 minutes or more into the game and the pc crashes.

- With endless internet browsing, i have found these possible reasons and fixes:

Possible Reasons:

1 OVERHEATING :
My Graphics card is a GTX 480 Nvidia - its considered a good card, but becomes very hot, and the CPU fan and heat sink has 2 pins that broke, causing the heatsink to not fully attach itself to the CPU.

Result: ( Faulty CPU )

2 GPU - graphics card Failing
Possibly my graphics card has reached its lfetime ( 2 years ) of generally working in heat, causing some components to malfunction )
Result ( Faulty GPU causes issue in hardware causing PC to crash ) - not sure if thats possible.

3 MOTHERBOARD and power supply:
After looking through the Event Log, i found the CRITICAL Error stating: Event ID (41) Kernel-Power happens every time my computer crashes, and after reading countless forums, i found that this is a simple Event message showing the Pc suddenly swtiched off and not cleanly saved all work.

-Causes may be Loss of Power, Restarting, Power supply failure:

There was a Thread that suggested that the issue could be a Damaged motherboard that would cause this issue.
I pray to god its not, becouse this desktop Pc was actually shipped from country to country once, by a shipping company.

The other Cause could be a insufficient or Faulty Power supply, which cant be possible considering its a new power supply that i recently bought to FIX this same issue i had.
It seems that the old Power supply had a short circuit of some sort, and didnt want to swtich the Pc back on, and right after getting the new power supply, the Issue disappeared for the Time being, until recently this issue ( Random restarts ) began again.

my power supply is a Corsair 780W i believe, and should be a good peice of hardware, since its lifespan is no less than a year.

4 Viruses or faulty Windows 7:
I ruled this out, since i got numerous anti viruses to see if i have any issues.
I havent checked windows fully, but i hope the OS is stable, which i think it is.

5 Memory:
I ruled this out, i havent seen any Memory related problems since i have 6GB (3x2GB) Corsair Dominator, DDR3 sticks, which worked fine.


hardware :
650W Corsair CMPSU-650TXUK TX, 86%
Intel Core i7 950 Bloomfield 45nm,
1TB Western Digital WD1002FAEX Cavi
6GB (3x2GB) Corsair Dominator, DDR3
1536MB EVGA GTX480, 40nm, 3696MHz G
Asus P6X58D-E, Intel X58, S1366, PC
120GB OCZ Technology Vertex 2E, 2.5


Windows 7, 64 bit
Intel Core i7 - 950 3.07 GHz 8 cores

If you need any other specs, let me know.
Please feel free to add any comment.
Thank you :)
