Hello, Today upon booting my pc I heard a very loud buzzing sound coming from the tower which seemed to be some sort of vibration. When touching the PC it would disappear. After turning off the pc and turning it back on it didn't do that again. About after an hour of some web browsing my monitor came up with a message that said the signal was lost. I restart my PC and it was back to normal again but the issue came back a few minutes later. Let me post my specs,

Intel Core I5 4670K
MSI Z87-G45 GAMING
8GB Corsair CMZ8GX3M2A1600C9B
Sapphire Radeon HD 7950 3GB
Corsair TX750M
Windows 8.1

Now that is out of the way I will post some of the things I tried. I switched out the cables and the monitor, didn't work. I booted into safe mode and uninstalled my video drivers and then installed the latest drivers, this also didn't help. I completely took apart my computer and put it back together. Made sure every screw was tightened and every cable was firmly in place. I re seated the CPU and made sure the thermal paste wasn't an issue. I made sure the video card was in place properly. Tried a single stick of ram.

I don't have an additional gpu so I cant switch that out to see if that is the issue. I'm not sure what the problem is, if anyone has some advice for me I would be grateful. Thank you.

Edit - I also forgot to mention that I heard the Video card fan speed up abnormally a few times.

check for any hdd errors or bad sector.
Trying connecting your display with your motherboard and see if the problem still there.
Make sure you cpu cooler is running and what are the cpu temperature you getting?
