About 1 week ago I noticed that whenever I had turned my computer off and then turned of UPS, on restart the computer time was wrong. I assumed a battery was past it and didn't really worry, just reset time each day. However now a second issue has occurred. Every time I restart my computer (from hibernation or reboot) the BIOS options come up. This has always happened occasionally, but I was able to reject changes and exit and start up continued normally. Now however I can only successfully exit by saving changes (of which none have I made). Once started the computer appears to functioning well. My worry is that a) it's annoying, and b) maybe a major melt down is arround the corner. What do you think? (computer is 6 years old, but capacity upgraded over the years, running XP)

get a new cmos battery

i sorta agree with getting a new battery, BUT, if battery was dead, you wouldn't be able to boot, system would not find the hard drive n boot the operating system. but, would try new battery first. Just my opinion

you can still boot with a dead cmos battery and it might not be totaly dead yet
