I have a problem with my PC that I hope you can help me solve.

The problem: Crash to desktop while playing games (CS, TF2, Skyrim, BF3, and more), after a random time, somewhere between 5 minutes to 2-3 hours. Usually with error about graphics driver crash.
Before you say: update the Drivers, Here is a list of things I have already tried to do (for the past 2 years)

  • ■ Reinstalling the graphic drivers (in safe mode normal mode, uninstall and reinstall install beta and older versions- I tried everything)
    ■ Formatting the computer.
    ■ Cleaning the computer from dust (the computer located in a opened space).
    ■ Check the Temp (after cleaning the temp does not pass the 70C)
    ■ Change the Graphic card (I had NVidia GTX 465 and now I have AMD Radeon HD 7870)
    ■ Trying different benchmarks to crash the computer (And all failed, i.e. I am unable to intentionally reproduce the bug).
    ■ Checked the BIOS info.
    ■ Tried to check the RAM with Memstest86.
    ■ Reinstalling DirectX.
    ■ Changing GPU to a different slot.
The only thing to show a problem (except games) is prime 95 that gets an error after one minute.
(The error: FATAL ERROR: Rounding was 0.5, expected less than 0.4)
In very rare occasion I get BSOD (even in IDLE) and the error massage is different each time.
What I think might be the problem: the PSU does not have enough power to supply all parts simultaneously or some bug with the motherboard.
My spec is:

  • ■ System operation: Windows 7 Ultimate 64
    ■ Motherboard: Gigabyte X58A-UD3R
    ■ Processor: Intel(R) Core(TM) i7 CPU 930 @ 2.80GHz (8 CPUs), ~2.8GHz
    ■ Memory: 6144MB RAM (3X 2GB OCZ DDR3 triple channel)
    ■ Graphic card: AMD Radeon HD 7870 2GB GDDR5 (I had NVidia GTX 465 before)
    ■ Hard disk: WDC WD10EARS-00Y5B1 (green)
    ■ DVD\CD ROM: Optiarc DVD RW AD-7240S
    ■ Computer case: Thermaltake M9.
    ■ PSU: Thermaltake thoughpower Qfan 650W.

yes.
I also reinstalled windows while using the old one.
after the fans of the nvidia stopped working I change it and uninstall everything and reinstalled every thing again (installed the corrects one).

Man, this could be a tad bit tricky. If you reinstalled Windows and got the same issues, maybe its the way Windows is installing on your computer? Did you install Windows via a disk or a USB flash drive?

Sometimes if you install Windows off of a disk, the install files can get a bit wonky. I would advise making a USB bootable disk. You can use a program call Win7 to USB, and you can put your Win7 install on that flash drive.

BEFORE YOU DO THIS, though, I would advise just triple checking with the manufacturer of the graphics card.

I had the problem with both graphic cards NVidia and AMD.
Is there an other solution before I format it again? I would like to try other things before formatting it.

So if you had the problem with both of your graphics cards, we can lean even more towards a software problem. I know you don't want to reformat again, but what else do you think can solve this issue? Both of your cards are doing the same thing, so the only other thing I can advise is putting the graphics cards in completely different computers, rather than just changing the slot on your motherboard.

So you're having the same issue with both of the graphics cards even after a fresh install. You tried different slots on your motherboard. It's not your RAM because you said you tested it with MemTest. I can only think of a few more issues.

Overall problems with your motherboard
Processor issues
Hard drive issues

I would advise trying a different motherboard if you can do that.
