In the last week or so the computer clock in the taskbar has started to run very slow. It loses about 7 hours in every 24. At the same time disc transfers seem to have slowed down a lot. I have increased my memory size and stopped some programs loading at start up plus run all the usual diagnostics etc. As a result the disc access has speeded up to nearly normal but the clock still loses time.
The motherboard is an Asus A7N8X-X with an Athlon XP-A 2800+.
If it loses time with the computer powered up, it isn't the CMOS battery. If it loses time with the computer switched off (at the mains for some), then the battery is the usual cause.
Check for type - usually a CR2032. To replace, ensure computer is powered down and unplugged. Ideally earth yourself, but touching the case frame is usually enough (and don't wear those nylon flares!). The old battery is usually held in by a simple spring clip ( an old Bic Biro cap is handy if stuck, but don't force it). Try to change them over in as short a time as possible, otherwise you risk losing your CMOS settings.
