I started having troubles ever since I updated the drivers for my GPU to play Watch Dogs. I also changed the vsync option to 1 from 0 then. The first time after I updated, I played it for a few hours before I started receiving errors that said the display drivers stopped responding and were recovered and I would lose my audio.
I started experiencing more serious problems randomly in between my playthrough where my display would crash with a random dark color like black and I wouldn't be able to turn off or restart my PC.. after a while, the driver would crash when I played a Video too. I wasn't able to boot most of the times since then. It doesn't show the bios screen most of the time it gets to windows now. I have an led strip which always lights up. I opened my case and switched the pci cable of my GPU to a spare one which got my PC to boot and get past the loading screen of Watch dogs then and it worked for a few minutes again and recently I tried booting it with one ram stick and it worked with fine again so I tried it with two sticks yesterday and I experienced no problems for more than 6 hours of playing it to test it but when I tried to turn it on today, it wouldn't boot like before. My cooler's light didn't turn on and my GPU and case fans weren't running like before. I can hear a sound of something trying to run before it stops.. I have no clue whether it's my psu, gpu or motherboard that's causing it or something else..
Also, I'm new the forums and I would like to say hi
Update: I reset my cmos which made it boot up and it showed a screen which said it had been reset, then I changed my bios again to enable IDE for my hdd qns enable S.M.A.R.T. it worked like normal again but I found that my GPU and ram temperatures were very high, gpu usage was 72 and max temperatures were near 103. I have a zotac GTX 660. When I restarted, it wouldn't boot. I reset the cmos again the coolers lights turned on for a second and the PC restarted without the light and it started turning on and off for a few seconds before I shut it down and tried it again, but this time it wouldn't start anymore. I also remember the screen that said my UEFI defaults were loaded showing up before whenever it did boot up.. but this is the first time I'd physically reset it myself
