I have an HP which I purchased refurbished a couple weeks ago. The last couple days it's been restarting spontaneously. Usually something has to set it off but it does it without warning. A few things that have caused it....
Tapping the side of the computer
Plugging a monitor cable (while on) into the computer
And once or twice it's just restarted without anything happening, though I believe that was shortly after it had jsut restarted for one of the other reasons.
My questions are what could be causing it, and what can I do about it? I'm debating about simply returning the machine because it is on only a 30-day warranty. I have adjusted a setting through the control panel so the machine will not restart after a system failure, but this didn't work as it restarted once again. So I am wondering if there is some problem with the power source, though there is another computer going through the same power strip that has not had any problems.
Any help is appreciated.
