Hey Lobo,
By what you are describing I assume it can relate to several things:

1) Power supply might be going to die.
2) Motherboard issue
3) RAM (Memory) problems.
4) Graphic card problem

So, the first thing you are going to do is run a memtest
To do this you will press the widows key + R and then write down "MdSched.exe"
This will start a memory test - let it run after the computer will reboot.

Did it find anything wrong ?
If not, things are probably fine.
If you have two memory cards, try removing one and run the system as a 4GB. All ran well ?
Try to replace it the 4GB with the other one we just removed.
All is well ?
Great - then it's not the memory.

Afterwards, we can check the GFX card. Since you wrote you tried many other drivers, see if you can remove the card and run the system with the onboard graphic card. (it's ugly, I know). Try for a day or two.
Stable ? Card's fault.
Still bad ?
Moving onwards.

At this point, we are in a tough spot, since we cannot test on our own the motherboard nor the PSU (power supply unit) without proper tools.
Thus, I'd recommend sending the PC for a lookup at a PC shop.

Hope it helped you out man.
