I built my first gaming PC about 2 weeks ago and have been loving it. Everything ran fine up until a few days ago. I noticed as I was moving my mouse cursor across the screen it started to freeze for a split second then continue. This started happening more frequently and then I noticed it while I was in games, I would try to move and everything would freeze for a second then go back to normal. It's gotten worse as time goes on and is now happening when I'm browsing, in game or just on the main screen of windows. I think it might be a HDD issue because I was watching the resource monitor and when it would freeze there would be a spike in the Disk section. Could a bad HDD be causing this or am I way off?
I have had bad hard drives do this before. Sometimes, they make a PC incredibly slow but it doesn't freeze, and sometimes they begin to fail in such a way that the PC will freeze EXACTLY as you described. Watch the hard drive light. Is it on continuously while the freeze occurs? No flashing, just solid on.
So I ran WD DLD and di bith the quick scan and extended scan and passed both scans. The freezing seems to be getting worse. I RMA'd my Power Color 7870LE for a Gigabyte 7950 Windforce 3 because the Power Color was running very hot, around 90c-92c under load. I just got it in the mail so I'm hoping that could be the cause. I'll repost after I swap them out
So I just put in my new GPU (Gigabyte 7950) and a Corsair H55 liquid CPU cooler. From the 20 min I have had my PC on the lagging seemed to stop. Is it possible that my old GPU (Power Color 7870 Myst Edition) could have been causing the lagging problem the whole time?
After a few days of testing and some heavy gaming still no lag! I guess it was the GPU causing the problem. I haven't seen my 7950 get over 50c even under heavy load but after the problems I had I'm keeoping a close eye on the temps
It was a week old GPU so no dust. I have a NZXT Guardian case with 1 120mm intake in the front, 1 140mm on the side blowing right on the GPU and a rear intake through my Corsair H55 radiator and a 120 exhaust on the top on the case. I think it was just a bad GPU from the manufacturer. It was running at stock clocks around 90c with 100% fan speed. With my 7950 Windforce 3 I haven't seen temps above 55c and no lag so problem solved for now. The 7870LE performs great (a few fps less than my 7950) but runs very hot. If you plan to get one make sure you have excellent air flow
