Don't go over board on the paste. Only a very small amount smeared on the chip and not the silicon is needed, too much can give you problems. Personally I would not bother with a 250w power supply any thing less than 400W these days what with power hungry graphics and multiply hard drives, the original may be failing under load, though why the key board and / or the mouse would cause this is beyond me. I did have a power supply get very temperamental last summer when things were getting very hot and after installing a new graphics card that was drawing more power than the old one. I connected a multi meter to one of the power cables and kept an eye on it for a day. The machine in question was freezing and some times rebooting for an hour or two during mid afternoon, (hottest part of the day), and after cleaning fans, heat sinks and putting another fan in the case and not curring the problem, the meter showed a drop when things were hot -- Guy Fawkes, the only man to enter the house's of Parliament with honest intentions, (he was going to blow them up!)
