The computer turns on perfectly, but there is nothing on my screen plugged in through VGA, old computer
Im not sure of the specs
I know it has a 7800gtx gfx card
And a crap power supply not sure about other parts
Any ideas thanks

Did it work before? does the GPU need external power supply? try clear CMOS.

It doesnt need an external power supply
Yes it did work before just the wireless card broke a while back and i couldn't fix it so it was just sitting in my sisters room gathering dust.
Kind of a noob how do i clear CMOS is that the little battery thing?

turn of at the wall, remove battery, wait 30 seconds to make sure, stick back in and try again.

Well that didnt seem to work mate, i dont know maybe the GFX card has gone, the fan spins up on it though.. not sure

I got no further ideas apart from seeing if you can put the 7800GTX into your pc if its pci-e and not agp.

Menthis · 29 Apr 2011 at 19:04

I guess i could try that thanks

Nope the graphics card works fine in this computer.. what else could it possible be
A hard drive failure?

Put your psu in the other pc? a pain i know.

The pc will boot up and display BIOS even without a HDD.

God that is a pain but i shall try none the less, nothing like a bit of trouble shooting

This did not work, and was not happy as while i was putting the PSU back in my computer i managed to break my monitor stand lmao, a bodge job to fix this...

This has happened to me the last few days. Been trying to troubleshoot. Usual checks with swapping everything out. I am down to CPU and GFX card. Odd thing with mine, no matter what I do get the same smyptoms, fans spin for about 2 seconds then it shuts off. I get no motherboard beeps to help diagnose. I think it is the CPU. Tested different ram, psu and motherboard so far. Try testing the motherboard out of the case with the bare essentials plugged in.

I will try that at a later date it was not fun watching my monitor snap

And this is different as mine stays on, just i get no image on the monitor, ive tried the PSU and GFX, i will test mobo and CPU at a later date
Thanks for the advice mate

Sounds like GPU failure to me. Possibly board though.
