I am having this weird problem where my system will either restart all of a sudden or just freeze. Sometimes it just gets me logged out of Ubuntu and I have to login again.
Not sure if its related, but sometimes programs crash too. Chrome (can be becuause of dev version), Skype etc.
Are there any logs which I can check what happened or if something crashed/failed.
Any tests that I should try running? Memtest or some HDD related perhaps?
P.S. I am running 10.10
Edit: The issue has become more serious now. I just faced the issue 10+ times in the last 15 minutes. Twice it got hang and other times I got logged out for no reason. When the system got hang this time, I saw that Caps lock & Scroll lock were blinking.
Could it be because of some programs?
