Hi, my PC is running Windows XP Home SP3 on an Asus A8V-VM Mobo and was only installed in 2006. I have noticed on several occasions that when I boot my PC my System time is slow. On looking on Google for a similar problem shows that this is usually down to the CMOS battery. However, since I only installed the Mobo in 2006 from new makes me doubt this as I thought that these batteries lasted for a longer than 2 years. Any advice appreciated.

It depends on how you use the machine. If the machine is left plugged into a switched on power socket then there is small current being taken even if the machine is switched off. If the power is switched off at the socket then the backup battery is in use and may not last longer than a couple of years. Cheap batteries will not last long anyway.
However, as using lithium CMOS batteries appears to be prevalent (the C2032 seems the most common), it would be doubtful if the battery had packed up in such a short time unless it was already quite an old one.
But as suggested it won't do any harm to try a new battery.
