Hi I have a problem I have not encountered before.

I'm trying to fix up an old PC to use as a server, it probably hasn't been used for about 2 months and now won't successfully boot into an OS.

It is a fairly old windows XP fujitsu desktop. RAM upgraded from 1 to 2GB. Pentium dual core. On board graphics. Was working perfectly as an office PC until it's redundancy 2 months ago due to upgrade. I decided to salvage it but the ah heck won't boot up fully.

I'll try to describe the problem in detail...

PC was successfully passing POST without an issue, windows XP started up but at the log in screen the display would shut down showing a 'no input' message. PC still running (LEDs on and fans spinning away). Could not shut down using keyboard shortcuts or even the Jedi death grip (ten seconds power button), had to cut the power at the mains to get it to switch off.

The many things I've tried...

Tried booting using 3 different Linux distros on bootable USBs, same result. Even with GpartED.

Tried removing HDD and booting from USB, tried reseating the RAM, tried 4 different monitors, tried graphics card out of my other PC, tried XP safe mode, same result every time. Can't get booted up to update drivers or anything.

Ran GPartED's memtest, all clear.

Then it got worse...

Removed CMOS battery and drained capacitors to reset bios. Now POST shows error message "processor had been changed" F1 to continue... still goes to boot problem. Bought new CMOS battery. No change. Now I get POST error about the processor every time. Was going to flash the BIOS to latest update to see if it fixes this problem but i doubt it will fix my boot problem so gave up on it.

Frustrated with it because it's a tidy case with a nice quiet fan, yet room for 3 HDDs. Perfect for home server. It's also one of these stupid back to front and upside down motherboards so i can't even reuse the case as I won't find a motherboard that will fit in properly.

If anybody has any ideas of other things I can try please throw them my way. I'll have a tinker with it again in a few days

Thanks for the reply. I would set cpu speed but the bios menu is terrible and I can find nothing in there about the cpu. might go to the effort of flashing the bios before I try anything else

Both problems now solved!
Turns out I had a bad stick of ram that gparted memtest hadn't picked up on. I went back to basics and started removing things to see if it worked, and taking out one of the ram sticks sorted it.

Once this was done I reset bios to defaults and made what adjustments were necessary. Stopped the cpu error code.

Now to have some fun setting up my server...
