Blue screen on start up on Windows?

This morning my PC was fine. I didnt touch it or anything to upset the computer in any way. I turned it on and turned it on after work and a blue screen now appears, EVERY time I turn on the computer. i don't know what to do.

Can I do anything without having to pay out money?

Is it worth inserting my Windows XP disc to try and repair it?

Thanks for your help!

If it's a terminal where you can type things in on lines sort of like Command Prompt, try typing ''boot.'' Otherwise, insert your Windows XP cd, and I think it automatically boots off that and you can restore your OS.

Try a few things - As soon as you turn your machine on tap the F8 key every second or so - You should get Windows Advanced Startup Options - Try Safemode - if you get in do a system restore to a few days ago by clicking start run - type in msconfig and click OK - Hit Launch System Restore - follow the prompts..

If that doesnt work take of your side case a reseat your compnenets one at a time - RAM - any PCI cards - If that doesnt work - take one PCI card out one at a time - if you have more that one - Network card - modem...ect. See if you can find the PCI card that may be causing the problem.

Good luck
