CMOS Password Clear DIP switch faulty

By espressomorning ·
Hi, Just curious if anyone else has had a cmos password jumper prevent the system from booting. In this case placing the jumper in the normal position prevents the computer from even starting to boot. The power light comes on for an instant and then goes out. Removing the jumper allows the system to boot, but with the default bios. The previous power supply was going bad, lots of static discharge type sounds. With it still installed and the jumper removed, the system would try to start repeatedly, getting a little further into the boot process each time until it finally started. The battery is fine, the latest bios installed and a new power supply put in. Now the system starts fine as long as the password clear jumper is left off. But even with a good battery the cmos is lost if the computer is unplugged from the power source for more than a couple of minutes. I think maybe the old power supply has damaged the cmos circuit somehow and only the system power is holding the cmos. Any thoughts, it's a nuciance but not worth replacing the board over.
The board is a Elitegroup K7SEM Rev.1.0
Regards
