Problem :(

Hi!
I've been having a problem recently.
I used several gpu burn in tests and all is the same answer. I don't know why but when I go to do a gpu burn in test my computer shuts off.I just thought that the gpu wasn't strong enough to handle it, so I OCed it, I tested it and its perfectly stable OC.
My gpu isn't even that hot 33C normally and 40C under load. It can handle all the stress tests, just not gpu burn in... I have not the slightest idea why 🙁
My gpu is Nvidia accelero Xtreme 260

can you list the rest of your specs? I'm especially interested in make and model of your PSU.

Thanks

I've got AMD Athlon 64 x2 2.4GHZ 4800
2GB ram
Windows 7 ultimate x86
My psu is I think Colorsic and model is 600U but its strange the way my graphics card used to work with gpu burn in, but now it doesn't after I formatted my computer, exact same stuff.
Tell me if you want more specs
This problem also happens when I try to refresh the windows experience index, it shuts down 2 secs through it at direct aero assesment

okay,
what GPU do you have?

please make sure that you've installed the latest drivers for your graphics card from nvidia website

also please make sure (double-check) that you've connected the power cables to the card (check your GPU manual) at the rear end of the card the typically are 6 or 8 pin connectors for additional power to be connected from the PSU.

check that the GPU is recognized in BIOS, if it isn't, make sure the GPU is seated properly/correctly in the PCI slot.

That PSU looks like a very cheap no-brand make/model, which means that it's probably not rated for the Wattage that it advertises.
