Netvista booting problem

I have a Netvista 8311 with XP that fails to boot. I get to IBM loading page, sometimes F1 and press F11 to restore. At that point the computer freezes and fans come on. I re boot fans are running with black screen.
I purchased a tested matching motherboard off eBay. I installed it but DOA. Re installed
old motherboard went back to the same problems.
I also tried a different hard drive with Windows 98, blank.
I do get a no operating system message, configuration problem and security timed out.
I left the system unplugged for several days, removed battery. Made it to desktop before it froze again.
Confused, is it a motherboard issue, built 2002 with a capacitor problem, faulty power supply, hard drive gone bad or software problem?
Thanks for any help in this matter.

 

Copied boot floppy disc and started. Computer responds but within a minuet or so fans come on and computer freezes. Also installed another hard drive with Windows 95.
I got to Windows 95 page then the fans come on and freezes. Power supply or capacitors?

 

If anything i would enter the BIOS setup if possible and try from there resetting it to factory config, install your norm hd on the laptop (the one you would use on it everyday as changing hds with different os's arent doing you good if they came from other systems). See if it boots after that. To me, sounds like the BIOS may be on the fritz. Have you tried anything to modify it lately such as update?

 

The last update was in 2004. I removed hard drive, card , floppy and cd tried to boot.
Once again freezes after 45 seconds or so the fans are at high speed. Screen said video problem. Beeps change all the time from 1 indicating a short to 1 3 3 2 to a 1 3 3 and one long 3 short to multiple beeps. I now have a X 61 as a replacement for the 8311 but would like my Lotus notes. I believe you are correct BIOS is repeating a timed mistake.
I will pull the battery and let it unwind for a few months.

 

Should not need to leave it out for months. There should be an option to reset the bios in its config. Is that accessible?
