Sup all, Back in like 2014 I built a nice little pc with an 860k, r7 370, and 8 gigs of ram. Since then it has served me faithfully everyday and performed well on every game i have tasked it with. Recently, I decided to open it up finally, clean some dust out, install some better fans, a new cpu cooler, and do some better cable management. After this, when i booted up a game, after a couple minutes the screen turned into some weird distorted lines that were kinda the same color as the background of the game and there was a loud buzzing noise in my headphones. This only lasted a few seconds before it went back to normal. This happened a few more times over the next couple of days until one time where it happened but wouldn't go away. I let it sit for a few hours and then tried to turn my computer off. It was completely unresponsive to the power button, so i just turned off the power supply. When I tried to turn it back on i got a blue screen of death and an error message "bootres.dlll is corrupt" or something like that. I tried all the troubleshooting options like system restore, reset, startup repair, and even some command prompt shit i found when i googled the error message. Nothing worked, so I reinstalled windows. After I had reinstalled windows it seemed to work perfectly for awhile. Until I was installing GTA V and left my computer alone for a little bit. When I came back It had gotten the exact same distorted line screen as before, but I was able to turn it off normally. Upon turning it back on, i got another bsod with the error message "video tdr failure atikmpag.sys" startup repair, system restore, and all that stuff wouldnt work, but i was able to boot it in safe mode. I tried to reinstall the graphics drivers in safe mode, but it wouldnt let me cause of driver signature enforcement. After I removed the graphics drivers in safe mode, it would boot in regular mode normally but after a few minutes, always before i could install the graphics drivers the screen would just turn black. It would still be on, just rendered black. I let it sit like this for hours, but with no change. after i turned off my pc, i got the exact same bsod and error message, and when I got back into safe mode it would once again have the graphics drivers installed. Same deal with driver signature enforcement disabled. I tried about five hundred times to get the graphics drivers installed but the screen would always go black before i could get it done. After a while. I came to the conclusion that maybe after i put in the fans and cpu cooler, it wasn't getting enough power since I only had a 430w psu. So today I went out and got myself a 650w psu. when I booted it up NOTHING HAD CHANGED exact same problem. At this point im worried that maybe i man handled my gpu too much and maybe messed up one of the little deals on it. Should I get a new graphics card? I have no other ideas to fix it. What would be a good equivalent to an r7 370? Is there any other possible way I can fix this issue?Any help would be greatly appreciated, thank you.
