I have a funny problem with my computer. when I plug it into a power strip I loose my desk top when it goes into power saving mode and then I have to reboot. If I plug it in to the wall without the power strip it works fine. I bought a new power strip and it worked fine for a week and then it started doing it again. Could it be the power supply? I set the hard drive on never turn off and it still does it. Any suggestions?
