I recently installed an older GPU of mine [Nvidia Gtx 650] and 600w Corsair PSU (80% efficiency) in my friends computer (HP Pavillion, no visible model). His old PSU was a generic 300w and didn't have a PCI-E plugin so I had to install a new one.
If I plug in the power for the Graphics card, the computer beeps 6 times at me (correlating to a GPU error based on error codes) , if I disable the GPU and connect to the integrated video source it starts up just fine. So this piece of hardware is obviously the issue.
I assume I need to find out what the motherboard is to get a complete answer but I don't see it labeled anywhere. Do you think this card is incompatible with it or could it just be a simple driver conflict ?? I guess I've been lucky and never had a PC deny a GPU before, much less one like the 650 which isn't exactly a monster of a card.
I'll look harder for labels on the motherboard indicating what it is, but do any of you have a general idea on what may be happening? Certain other forums online suggested switching the boot-up from UEFI to legacy and disabling secure boot, I'm afraid to take that action unless it's a last resort, since I have no idea what the difference of these two are and why it would work.
Thanks in advance,
Also forgot to note that he is using Windows 8. After doing more research about UEFI/Legacy it seems to me UEFI is a faster and more stable option so I don't see why so many suggested legacy on other forums. However it has seem to somehow fix this issue for some people.
