About a month ago I had to clean out my gaming pc because my GPU's where reaching critical temperatures. so I pulled my pc apart and started cleaning out all the dust. After that I uninstalled the CPU heat sink for cleaning. I noticed that the thermal paste was old and dried out so I cleaned it off and put some new thermal paste back on. Then I put the cleaned CPU heat sink back on. I decided to disassemble and refurbish the GPU's later. So I turned on my pc and checked the bios on start up to check my pc's temperatures to make sure that everything was fine. I continued with start up and tested my pc's temperatures while playing a game. After that I shut down. My pc logs off and says shutting down then the screen goes to no signal, but the computer stays on. Pushing and holding down the shut down button didn't work So I had to cut my pc from the power. It has been giving me this issue ever since. I'm always forced to cut the power. A couple of days latter I disassemble and refurbish the GPU's. All my pc temperatures our now good.
