Alright guys so here goes, I've got a new build, just finished it a week ago, and she was working beautifully, msi z270 gaming pro, i7700k, gtx 1080, 16gb gskill, kraken x62 cooler, 550w seasonic psu, 1 tb HD, windows ten installed as an update from 8, I overclocked the CPU to 4.8 through the bios using frequency ratios and voltage was at 1.36, everything was working fine been having long gaming sessions and stable temps then all the sudden today it crashes in the middle of a game and I get the blue screen machine check exception, it got hung up on (60%) restart and it did this multiple times, on one reboot and only one it said "overclocking failed, restore defaults" I hit f2 to restore defaults and it froze, I kept trying to reboot and I was getting no signal in my monitor, so I took out the GPU, removed the cmos from the motherboard for a minute and hooked up my motherboard to the monitor using a dvi, was able to get into bios and then it froze, now I'm back at square one, no signal to the monitor, I sunk two months of savings from my crappy job so I could have this sweet release to look forward to when I come home, any suggestions on a fix guys?
