Please can you help me, my clock slows down by about 5mins in 3Hrs, when I shut down till the next day the clock keeps time, it`s only when I`m on line that it looses time. Do you think I need the battery changing? if so I know where it is on the mobo and can pull it out, is it just a case of swapping them over or does the computer need configuring in some way after. As you can see i`m not techie in any way so could you keep any replies simple, many thanks. Win 98, 256 ram,450 Mhz P3.
