So my pc will run for a while, then randomly restart like 3 times over consecutively, then stop. Then this would just happen randomly all day. I have ran diagnostics, updated all drivers, reseated RAM, used a repair tool to repair everything I could and nothing works. So far all I have got from a diagnostics is a program called 'taskhostw.exe' uses 98.7% of my CPU sometimes. But thats it. I have no idea what the problem is as my PC coulds run for a few hours, then just randomly do it, or it could run for 3 minutes and just randomly do it.... PLS HELP
