I have a PC running Windows XP SP2, and I face a problem in it and need my PC to boot in safe mode.

But when I choose safe mode from the boot menu, my PC restarts automatically!
So what's the problem?

does it start loading a couple drivers and then restart? Can you hear anything odd? light clicking or grinding? I had a computer yesterday do this and it was a hd failing. – Logman Aug 4 '12 at 18:18

You should get a linux livecd (SystemRescueCD or Parted Magic) and see if you can mount the hd. If you can, back up your data before you start trying to fix anything.

Yes, it's loading some drivers and then restarts! and I don't hear anything odd! Thanks for the link. Any other ideas? – Mark Aug 4 '12 at 18:30
if you can mount the hd, you can run tests on the hd (SMART/TestDisk). HD could be failing, partition corrupted... alot of things. If the hd is fine, it would be easier to do a complete install. Recover data before you do anything... – Logman Aug 4 '12 at 18:45
