faulty gfx card

[dunkler]

Hi
I've got a Geforce 8800 GTS G92 which doesn't want to output anything on monitor, PC won't POST, i got one long beep and 3 short and fan is spinning at 100% . My first thought was at GPU BGAs, knowing these card have problems there due to overheating stress in time. Reballed the chip, all looks perfect but the issues remains, same as before. Redone all solder joints at power supply part (capacitors, inductors,etc), but the same again
Has anyone any ideea what could be?

Best regards

yeah looks like a problem

that beep code

1 long, 3 short Conventional/Extended memory failure
can also mean ram in pc

usually case of:
ram failure or the motherboard is unable to access the ram.

take out your ram check them one at a time.
to see if it boots

reset your bios
you also might have up your voltages and timings on ram
when you are able to get in bios

Thanks for advice, i tried with another gfx card and the pc boots perfectly. RAM was checked with memtest86, no errors. I'm gonna check supply voltage to the GPU, maybe one vreg is faulty
