I've just upgraded my graphics card from a Radeon HD4850 to a Radeon HD6850. Once windows XP starts though it freezes as soon as the balloon pops up saying "Searching for drivers". I tried in safe mode and it doesn't freeze, but I can't install the Radeon drivers there (it complains about not detecting something). Back in normal mode it now doesn't come up with the "Searching for drivers" popup, but it still freezes at roughly the same time (about 10-20 seconds after starting).
I've put the old HD4850 back in and all seems fine.
I'm wondering if maybe it's the power supply? I have a 450W Corsair PSU. The wattage requirements for the 4850 and 6850 seemed pretty similar, so I didn't think it would be a problem, but I notice the box says 500W is required. I'm running an AMD 9950 Quad core cpu, one HD, one DVD drive and no other expansion cards. Does it seem likely I need a better PSU? Would it really cause the system to freeze at a time the graphics shouldn't be under particularly high load?
Otherwise, is it anything to do with Windows XP not supporting it? (I only just found out that DirectX11 cannot work on XP, but I would have assumed the 6850 wouldn't care about that would it?)
Or what other things do you think I could try? (If there's no other suggestions I'll be re-installing Windows next, but I'd rather avoid that if I can!)
Thanks!
