Ive started to fix an old no name computer with Gigabyte GA-7VM400M motherboard, BIOS WP. Ive replaced the power supply and recapped a half dozen elektros. It fired up but the mouse didn't work until I downloaded the FD bios mouse fix for it but I cant get the keyboard to work so that I can get into the bios? Ive tried F2, F8,delete,Esc on startup to no avail. It has the old style mouse/keyboard connections.The original HDD didn't come with it so I'm using one with XP on it that wants to be activated so seeing as I cant do that I want to install a copy of Ubuntu 10.10 that I have for it.Any ideas on how I can do this or am I wasting my time?

You could try clearing the bios and see if that helps.

I tried a USB keyboard with the same result, I looked for the 3 CMOS pins to reset it but all I found was a blank section were the pins should have been? Very strange,anyway I took the battery out and pressed the power button and waited a few minutes to make sure and now it wont boot up! Its on a page now that says CMOS checksum error- defaults loaded? The boot order is Primary master:Lite- on LTR-52327s. primary slave:none.Secondary Master:WDC WD5000AAKB. Secondary Slave none. System health OK.  Memory test OK

That is not how I clear the bios. What I do if there are no bios clearing terminals, is take the mobo battery out, (with ALL power shut off), and either leave the mobo battery out for 24 Hours, (to drain capacitance), OR short the mobo battery terminals together. i.e. connect the negative to the positive for a few seconds to drain capacitance. Then once that is done, replace the mobo battery in it's socket, THEN boot up the machine.
