Answer 1

You either have a trojan, or a worm seen both happen to friends of mine, will have to format, and start over

Answer 2

this is where you need your windows xp cd if you put that in you need to get into bios menu found at the start up screen there should be an option once there you need to set your computer to boot from cd once it loads you will have an option to repair the C drive or what ever your master hard drisk is set to it will appear that it is reinstalling windows but dont worry you will still have everything once completed

***NOTE*** you will need your origional product key as it will ask for it again any questions about that you can just ask

Answer 3

Other possible causes:

-Overtaxed or bad power supply
Swap it out with a different(preferably higher wattage) unit.
Also, always use a reliable brand, like Antec or Enermax. Off name cheap brands(even high powered units) can have one voltage leg that's insufficient to handle the load.

-Bad memory
Run Memtest86 to check it(it runs in DOS from a floppy).
If it fails, then swap it out with known good memory.

-Bad video card.
Make sure it's fully seated, it's fan is running, its heat sink is securely mounted, and its fan and heatsink are dust free.
If those are OK, then swap it out with a known good card.

-Bad MB.
Check for bulging, leaking, or ruptured capacitors.
If they loOK ok, then swap it out with a known good MB.

-IRQ conflict with a network card(NIC).
If no problems show up for the NIC in Device Manager on the original HD, then remove the NIC from Dev. Mgr., shut down, remove the card, and restart.

-Viruses and spy-ware.
Update your AV program on the original HD, and check for viruses.
Also, run Ad-aware, Spy-bot, and CW Shredder to remove any spy ware

Also, run an external fan with the computer's cover removed() to check for overheating.
