PC only turns on after resetting CMOS
LockedI am working on a Dell Optiplex GX270 (ATX). The 5V light on the MB was blinking and of course, the PC wouldn’t turn on. I replaced the P/S and the issue seemed solved – now the 5V light is on steady but the PC has an issue turning on.
The only way to turn the PC on is by unpluging the P/S from the wall, taking the CMOS battery off the MB, putting it back and plugging P/S back on the wall. At this point, the PC automatically comes on and I proceed to setting the Date/Time on the CMOS.
After shutting down windows, the PC will not turn on unless I restart the process above.
Unless I take out and put back the CMOS battery, the PC will not start up.BTW, the battery is fully charged.
Any ideas?
