So I recently downgraded from windows 10 as it was hard crashing giving me error messages like "Critical process died" or "Memory Store error"(or something along those lines) and now on windows 7 it is doing about the same. It is very random, some days it wont at all, some days its within 5 minutes of boot up with nothing running, and during gaming. Sometimes it freezes before crashing and I can still hear audio and talk to friends, sometimes it instantly blue screens. Any ideas? Ive checked my disks, did a memtest, reapplied thermal paste. Windows update will just go on forever if I click check for updates, and I noticed in device manager I have an exclamation point near one of my USB controllers but cant fix it...

Quick sugession
If you have more than 1 ram stick, remove all and install only 1 ram stick.
Go to safe mode in windows 7 (search on google if you don't know)
Wait there for 10 minutes.
Try to run something like softwares , games in safe mode.
Restart your pc in normal mode.
I think the problem is in your ram or hard disk
Hope it is helpful.
