New Radeon 7750 has error message - VPU recover has reset graphics accelerator as it was no longer responding - PSU problem?

post #1 of 4
Thread Starter 
Hiya Ive recently got a Sapphire Radeon 7750, Ive installed it and every now and then my pc freezes, screen goes black for about 30 secs, then comes back on and i get an error message saying -

VPU recover has reset your graphics accelerator as it was no longer responding to graphics driver commands.

Then i can continue as normal.
It has happened 4 times - 2 when no programs were open at all and the desktop froze, 1 when playing a game (civ 4), 1 when running outlook express.

I think the graphics performance comes right down as scrolling is a bit jerky after that.

I looked at new drivers but there are no more recent ones.

Im thinking of sending it back to Amazon, does anyone know why this is happening?
Could it be my PSU? The minimum requirements are listed as 400W PSU.
I have a 400W Corsair CMPSU-400CX
Its old but its a good PSU i think
Its certified 80 plus (dont know what that means)
It has
+3.3V (20A)
+5V (30A)
+12V (30A)
-12V (0.8A)
+5Vsb (2.5A)

Does anyone know if thats OK?

I was wondering if it was a bad board and sending it back, maybe getting a Radeon 7770, which needs 500W and a PCI-E 6 pin plug (my 400W has one of those) and just seeing if it worked on my 400W.

No idea if thats possible or not, it seems not, but I dont know how fixed these thing are.

Any ideas? Could my 7750 problem be due to my PSU?

And if not, are these PSU reqs quite fixed, or can you squeeze performance out of a well built lower wattage PSU?

the psu requirements are always exaggerated. you can easily run a HD 7850 with a Corsair CMPSU-400CX. was your PC working fine with the same psu before you got the HD 7750. if so then your psu is not the problem. mostly its a faulty graphics card. install the 12.11 beta drivers and 12.11 cap 2. test your card with benchmarks and games. if it keeps freezing and black screens persist return the card. get a HD 7770 if you can afford it. your psu is capable of handling it.
