Hi all I've had a problem starting earlier today whereas I installed the latest AMD drivers for my Sapphire HD 7970 Ghz 3GB Vapor-X GPU. Around that time I started getting black squares/blocks in random places across my display (I believe these are called artifacts). It has become very annoying and I fear something in my rig is malfunctioning. I have taken my HDD out as it was getting quite loud and it's fairly old now, I don't know if that was the problem or not, but alas I tried it anyway.
In my effort to fix this weird issue I have reinstalled windows and installed an older version of the AMD Driver. I really am at the end of my tether as I seem to have issue after issue with my computer. Maybe it was a bad build when I first built it or what.
Anyway, I've tried switching cable from HDMI and DVI also but to no avail.
See if you can borrow another GPU to test... (if problem follows the GPU it's RMA time again....)
And if you've "lost" two cards already I get rid of that power supply FIRST. (hey, I've bought six (6) Sapphire GPU's never had a single failure ....)
The first problem was when I had a dodgey power supply before. I'm no expert in these situations at all but from the research I did and what I had been told at the time, 600W is more than enough to run what is inside my case. I'd like to think there are a number of ways to troubleshoot this issue to determine the DEFINITE problem and not just throwing my card at the manufacturer.
Your welcome and good luck hope it works out for you.
Just to add I'm using the onboard graphics now and I haven't had a single "artifact". I believe it is the GPU. Don't know why it's happening to me constantly. Think it could be dust build up or not enough cooling. Gonna beef up my rig with a bunch of fans I think.
Does your I5 have integrated gpu is so you need to disable them in the bios and choose the pci only slot for your gpu card my opps for the day sorry be sure the igp is disabled or turn off in the bios of your board then enable the pci slot for your discreet gpu....
