Hey guys! I am having a weird issue with me PC. Can't figure out what it is. The thing is my GPU used to hang up and freeze the system when under load like gaming or stress test. This happened before so I opened it up, cleaned it, applied a fresh thermal paste . reattached the heat sink and boom, it started working! But after a year now it is doing the same again but, i have another issue! After a fresh windows 7 pro install, when I install the AMD drivers, my windows doesn't load. The windows loading screen shows up but the windows doesn't start. BUT, when I revert back to the last working state when the AMD GPU drivers were not installed, windows works. I am not sure what the problem is as i have installed the latest and old drivers multiple times and had the same issue. I have yet to bring another GPU and see whether it works or not but what if its the motherboard?
