Gomer Posted September 23, 2008 Share Posted September 23, 2008 Hello - I have a 520Hg psu that works fine in all respects except that if I turn the psu off at the switch and then turn it back on, usually after several hours, the computer boots automatically, or tries to, but fails with the CMOS being wiped. When this first happened I thought it was the battery, and replaced the battery w/o first checking it. Initially I thought it fixed the problem, but after leaving the computer off overnight when I tried to boot the next morning My BIOS settings were reset to default again resulting in a no start due to my RAID config not being part of the default settings. I have checked the new battery and it has full power. I have cleared the CMOS with the jumper as well. I have since found that if I just close Windows and don't switch off the psu that Windows will boot every time. So what do you think ? Link to comment Share on other sites More sharing options...
