Hi, I previously had a problem with the primary or administrator password which I was able to resolved thanks to the "MasterPW exe." program. The new password worked but now I'm getting this message as soon as I turn on the system. Nothing happens whether a press F2 or S or R as the message requires. I haven't installed anything since I was unable to use the computer for quite a while. I have Windows 98. Any advice would be appreciated.

I/O error caused in Bios inf

Either update the Bios to current version
Or reset bios to defaults

Read here on updating your bios

Also let us know the outcome

Would you please give me instructions on how to reset the Bios. I press F2 but nothing happens, the system freezes after getting the "I/O card parity iterrupt at F000.......". Thank's

Actually before deciding to dismantle it
(Pretty easy, 6 Screws underneath for Keyboard etc)

Maybe you should confirm the Ram is ok
By swapping one out (if there's two) and changing to DimmA and DimmB location
Ideally testing with known good Ram

Thank's for your advise but I've decided to take it to a technician since I cannot do it myself because I'm not so good at computers.
