I recently reassembled my system , after getting replacement RAM, mobo and CPU from RMA. The computer ran fine - until I do something that utilizes graphics hardware spceifically, be it gaming or watching HD video through DXVA (mkvs in media player Classic Home Cinema). This results in crash to desktop, with a pop-up saying the ATI display driver crashed and had to be restarted, and the occasional hard freeze or bluescreen (where the bluescreen again points to ati[something].sys).
Thinking that the... incident.. that led to RMAing parts had also affected my graphics card, I replaced my 5830 with a 6870. And thought I was home free.. until my graphics driver crashed again, although I am able to keep gaming for longer periods of time.
My working theory is that I need to replace my PSU. The 5830 crashed after less gaming because it draws rather more power than the 6870. My other theory, which I feel seems less likely, is that the PCI-E port on the mobo is damaged somehow.
My case is well ventilated, and I had no such issues prior to RMAing parts.
So - do i pull the trigger on a shiny new Corsair HX 650W PSU? or is there another likely culprit?
