ummmmmmmmmmm

have u tried to reset your bios?
i think u mite have to physically move a plastic cover from one pin to another.

this will reset your bios. i beleive this should do it! then u have to press f1 or something when u first start up your pc.

thanks guys, ok i already changed the battery and reset the CMOS using a jumper thing, but it still does the same thing, how should i go about with checking everything else? since the computer wont boot up i cant really scan for viruses... so should i get a new power supply? any ideas?

i woulndt bother with a power supply wont make any difference.

how abt taking out the battery for a hour or two? then putting it back in!?

Hi Alf

You definatly need a new CMOS battery, make sure you get a new one, rather than from off a market stall, you dont really know how long they have had them.

thanks yall, the my computer is working now expect one thing... Now my PS2 mouse port refuses to work!!! i have used two other mouses but my little arrow thing wont move! the port it self doesnt appear to have any type of damage...do you think its my motherboard??

Also, when i log in there is a message saying that my Anti virus protection has failed to load. is this a concern? Since my computer isnt hooked up the internet but i do transfer files to it via usb flash drive. the most recent one being Style Xp.

Ah! Scratch that, a quick system restore and my mouse is back on track. although my Anti virus protection isnt working even though i reinstalled it. i am currently using Defender Pro Anti Virus.

Did you uninstall the old version first and then reinstall ?

 

[Alf]

Yep, but that dident do anything, so i just used a diffrent antivirus
