Hi everyone,

I recently upgraded my graphics card from a 560Ti to a 280x.

Upgrade initially went fine.

However... after running a stress test (Furmark and CPU stress test) with mild overclocking to the CPU,
the computer will now freeze and restart every time a 3D application is started.
I also tried putting my 560Ti back in the system, and this card causes the same problem now too.

I'm reasonably confident that I have overloaded the 12V output from my old PSU, and to this end have already ordered a gruntier replacement.

My question is, is there likely to be any other causes for this problem?

PC specs:
AMD Phenom II 955 BE
MSI 880 GMA E45 motherboard
Radeon 280X
HDD, SSD, DVD etc...

(I know that my CPU/Mpbo is old... it is next on the upgrade list!)

What PSU do you have? Make and model please.

Though, your CPU is likely to bottleneck your GPU.

Sorry PSU is ANTEC NeoEco 620W.

Yep, I know the CPU is bottlenecking the GPU - hence the overclocking.

The PSU looks good to me. :) 

P.S.: the CPU will likely still bottleneck your GPU.
