Hi guys, this has been really frustrating me for about 3 days now.
I came home one day and logged into my computer to do some work, so I opened a couple google chrome tabs and logged into Facebook on one of them, I immediately noticed that videos were playing very slowly and were extremely broken, as in the colors were heavily distorted and the audio was unrecognizable. I also noticed that the page was lagging very heavily.
Naturally, I opened task manager to see what was wrong and I noticed that it opened very slowly, and that my PC was running at near 100% CPU usage. However I could not find a process that was using all my resources. I tried closing everything and it was still running slowly. My mouse cursor was jumping all over the place instead of moving smoothly as I used the mouse.
I figured maybe it was a freak occurrence and restarted my computer. It ran pretty well upon restart, so I started up League of Legends just to see if my computer could run it.
Normally, when I play League, I sit around 280-300+ FPS, but I noticed that after about 3 minutes into the game, I dropped to well below 100, sometimes falling to less than 20. I got a bugsplat and restarted the game, after which it did this again, starting out at 200-300+ FPS and suddenly dropping to below 100. I quit out after the game and gave up on it for the night.
Today, I came home and started it up again, but it seemed to be working fine, until I decided to try playing CS:GO. It ran very smoothly for a little while, but then it just straight up froze. The audio began clipping and the screen just hung up on one frame, I couldn't alt-tab or pause, and it took almost 30 seconds for ctrl+alt+del to do anything.
I opened task manager again and see 100% CPU usage, so I search around and find out that my CPU might be overheating, so I shut down my computer and clean it out with compressed air.
I turned the PC back on and it worked fine, but it was still a little hot, so I pulled back my CPU overclock and ran it at stock speed, then restarted. I noticed that i accidentally left one of the CPU fans leaning on the back of my GPU (it has a full backplate) so I turned the PC off again and replaced it.
When I restarted it again, it took an abnormally long time for my monitor to turn on so I decided to wait for it to boot, and then restart it again.
When I started it again, the DVI signal was completely gone. My Keyboard, mouse and speakers all turned on and worked, but the GPU would not output a DVI signal. I switched to integrated graphics, it's useable but I really want to be able to use my GPU since Fallout 4 comes out soon, and...well yeah.
TL;DR: Computer was freezing, cleaned with compressed air, now the GPU won't output a DVI signal but it turns on and runs.
Specs: CPU: i7-4790K
Mobo: MSI Z97 G45 gaming
CPU cooler: Noctua NH-D14
RAM: Corsair Vengeance Pro 16gb 2133 mhz
HDD: Seagate Barracuda 2tb
SSD: Samsung 840 EVO 250gb
PSU: Corsair RM 850 watt Gold-certified power supply
OS: Windows 7 Home Premium 64-bit
Any help at all would be greatly appreciated! Thank you!
(Also, I did full system virus and malware scans, both found nothing)
