Greetings everyone,

After updating the driver of my old GTX570 my computer began to crash more and more often until my old GPU died, I guess the driver I installed overclocked it

So I bought another GPU (GTX770), but it gives me black screen whenever I want to play!
I've been doing a lot of testing on my computer :
- memtest and everything is fine
- uninstall drivers with Display Driver Uninstall
- try several drivers
- apply a new thermal paste on my CPU
- have a clean windows installation working on a new hard drive
- trying another power supply unit (switched from an old 650W to a borrowed newer 450W)
- put the GPU on the second PCI slot of my motherboard
I used several monitoring tools including WhoCrashed who tells all the time that I've a CLOCK_WATCHDOG_TIMEOUT error due to a third party driver (but I did a clean install of windows with only official drivers for my peripherals)

I've tried a GT430 on my computer and it works fine, but the repairman I've been consulting told me the GPU wasn't faulty because it was working on other computers (I still need to test it with a friend's computer to be sure)
That GT430 doesn't need additional power supply, it needs only 75W to work and the mobo provides enough power, so I was thinking about at PSU malfunction? Or the BIOS of my mobo being to old?

I've also been trying different solutions from forums, like adding a TdrDisplay cooldown key etc...

What could be the evil root of my electronical misfortune?

Thanks in advance!
