What Luis was referring to the Power Supply Unit (PSU).
Can you boot into Safe Mode? If you can try doing a System Restore.Start> All Programs> Accessories> System Tools> System restore
When this opens make sure that "Restore my computer to an earlier time
" is chosen, and click on N
The dates appearing in bold are the dates that you can restore to, click on the date that you want and then click N
ext> to start the System Restore. This may take a long time to complete, and when it is done it will restart your computer. When the computer restarts and you have logged on as the administrator a Restoration Complete page will appear, click on OK to complete the process.
If you can't boot into Safe Mode, try this second method.
Start the computer and then press the F8 key when Windows begins to start. The Windows Advanced Options
Use the ARROW keys to select Last Known Good Configuration (your most recent settings that worked)
, and then press ENTER.
If a boot menu appears, use the ARROW keys to select Microsoft Windows XP, and then press ENTER. Windows XP
restores the computer to the most recent restore point. http://www.microsoft.com/windowsxp/using/h...re/restore.mspx
I'm inclined to agree with Dr_Manhattan's suggestion, if what I have suggested doesn't work, try their suggestion.
