While I was using ubuntu my pc sometimes restarted and then I switched back to Windows 10. However, even Windows 10 was restarting and the UI glitched after the creators update and not to mention how dufficult it was to update. But in order not to restart while using it every time I turned on my PC I ran memtest86. No errors... So I installed Windows 7 on my other drive(actually 2copies of Windows7) and it was still restarting. Running the Windows memory test of course gabe no erors and the PC wasn't restarting afterwards. Recently I have been getting messages that I have memory problems after Windows loads and I've also seen some messages that Windows doesn't recognize the signature of somefiles (even the ones from the boot folder). I have tried running avast scans but it takes FOREVER with my 3TB of files. I let it run for 2 days and it said that there weren't any viruses at the time so what could possibly cause this strange behaviour
