Apologies for hijacking this thread slightly, but I've also a question on upgrading the gfx card in a 4700.
I recently replaced the original X300SE with
this Radeon X1650XT but have been experiencing intermittent problems. Initially the PC would lock up during gaming, since I upgraded the drivers I now get the "VPU recover" error message box instead. It seems to happen fairly randomly, although once it happens once will often happen twice more in the next 30 mins or so, after which I have to reboot.
I think I've ruled out incompatibility with any other components, and I ran for a while with the side of the case off which I presume would help avoid overheating issues, so I'm wondering could it be that my PSU can't handle this card?
I might have a chance to swap it for a 7600GT, but if people think it's not a PSU issue I'll probably RMA the card.
[edit] Should have mentioned, apart from replacing the CD drive with a DVD burner, the machine is as it came, so has the standard PSU. I did add 2GB of memory, but even after I removed that still had the same issue, so that's not the problem.
