Need some help with this problem.

My computer has worked fine for the past 4-5 months I've owned it until I opened the case to install a case fan on the top. Simple. After installation, I powered the PC back up and got an error message on the BIOs screen saying: "CMOS Battery Low" and "CMOS Date/Time Not Set". I set the date and time and continued as normal. Everything was fine except I could no longer see any icons in the notification area. Changing the Bios date/time didn't seem to do anything as the PC's system date was still wrong; off by about a year.

On some advice, I kept the PC running for 24 hours to charge the CMOS battery, and finally restarted the PC due to a system update from Microsoft. The PC turned back on, but I couldn't see anything from the monitor, and did not hear the 'beep' from the motherboard. I made sure it wasn't my graphics card by swapping, which did nothing. I bought and replaced the CMOS battery with a new one, and powered the PC back on and I got the same two error messages at the BIOs screen. After updating the date and time again, I continued to logon no problems, however I still can not see my notification area and I still had to manually change the system date and time.

What happened to the PC?? I thought that by changing the battery the issue would go away but it doesn't seem to have done anything. What do I need to do to fix this problem? Is this a sign of the motherboard going bad? Any support would be appreciated.

By the way, how about the ASUS A32-F3 Batterij? I want to buy one and My computer is it time to retire?

Replace the CR2032 3V lithium coin cell battery located a bit left of the memory slots with a brand new one.
