I ran an ATI Radeon HD4870 on a COoler MAster 500W PSU in my computer and it worked fine for a few months, then I started getting blue screens and also flickering screens. I realised that the power supply may not have been sufficient? I've replaced the PSU and the blue screens have stopped, but I still get an almost constat flickering screen. Things I've done so far are:
- replaced the PSU with Corsair CX600
- replaced the ATI with Nvidia Geforce 9500GT to test
- replaced the monitor to test
After all this I still get a flickering screen. Does this mean that there may be damage to my motherboard or CPU? Is such damage possible given the situation? And what should I do...?
Any help would be much appreciated, thanks!
