My concerns is putting paste on, recently my laptop died, I pulled out my desktop that wasn't turning on, found out PS shot, well now it's up and I redid the paste, was burning a cd when it shut off, when it rebooted I checked my bios and it was running hot, redid the paste again and now its running between 58-70 C......I haven't tried to burn.....should I start looking for a new CPU?
