Difficult. there are several things that may do this. If you are unsure about it the simplest first step is to try a reinstall of windows.
1> Is it XP?, try booting in VGA mode (hold down F5 on boot up), this will bypass the video card, corrupt drivers or a failed card can cause this.
2.My next check would be on the physical memory failing , If you can boot it and get into the bios setup (usually F2 or DEL), turn off SILENT BOOT, the bios will run a quick memory scan on bootup which may throw up an error. Failing that download a standalone memory test tool. (sorry link deleted, no external links allowed)
You have to burn this to a boot CD, there are lots of others that run off floppy drives.
3. Failed motherboard. Needs a hard test with a diag board, you will need a PC bloke to do this.
4. The other thing you can do is physically unplug the hard drive and see if it boots up, At least this will prove the hardware works (apart from the memory under stress). As it could simply be a corrupt windows that needs reinstalling. Possibly a virus.
