it is probably an incorrect or incompatible driver/hardware with XP - what you need to do is update all your drivers and make sure they are digitally signed and are compatible with XP - when i say drivers i mean drivers for your hardware such as:
motherboard, graphics card, modem, printers etc and also check for bios upgrade.
If you need help let us know - also, ALWAYS do virus and spyware checks first.
My computer has been unstable and crashing for a long time now - several months at least. Its so annoying, I simply dont know what to do. Anyway I just couldnt take it anymore, so I formatted the hard drive a couple of days ago. It was a little more stable the day after I formatted but now I think its starting to crash again. It crashed once this morning. Its really unpredictable and sometimes it crashes several times and hour and I get blue screens (which say the system has halted due to a hardware error or something), random reboots and freezes while im doing stuff. Sometimes it beeps a low continuous beep right after it freezes. Im thinking it might be a hardware problem or a problem with the bios settings. Anyway its really pissing me off and any help would be appreciated its driving me completely nuts.
