System restarts on shutting down!

My old PC- a Pentium 4 restarts itself when I shut it down. I have tried reinstalling Windows(XP then XP again then 7 then XP then 7 again and finally XP now!!!). What could be the problem?
Its a P4 with 1GB x 2 DDR2 RAM(Even caused problem on a 512MB stick), some cheap PSU and I dont know anything else :(

If I unplug it when the computer shuts down(immediately before restarting), would it cause any problems?

There can be many reasons for this. Try the following and see if it works. It's not a final solution, but it may help indicate the source of the problem.

Right-click My Computer, then the 'Advanced' tab. Click the 'Settings' button under 'Startup and Recovery'. Then under System Failure, untick "Automatically restart"

As to your closing question: No, it won't do any harm if you time it correctly. But if you switch off power while the hard disk is being accessed, then the HDD may be damaged.

That's for BSODs?

Faulty power supply or bad earthing?

^ Those and other things. There are many possible causes for the OP's problem - driver problem, buggy software or hardware, even condensed moisture at some critical points on the motherboard.

@Ishu Gupta: I didn't say it's the OS.

If you re-install the OS then don't you have to re-install softwares and drivers as well? And I don't think the OP will install all drivers and softwares every time before he tries a restart.

Read your own post again. Don't you think the two sentences contradict each other?

Anyway, did you miss the part where I included hardware as a possible cause? Even moisture?

Not at all.
First part meant that he reinstall every software/OS/drivers so they are not the issue.
Second part meant that he was probably restarting between the OS reinstall and driver/software install. So you can't say that he was "reinstalling faulty drivers" again and again.

So it doesn't contradict the first part. More like builds on it.

No. I was just saying that its probably not a software issue and we should prioritise on finding/fixing hardware faults.

It's best to keep considering all possibilities. He could well be installing the same corrupted files again and again. I'm not saying that this must be the reason, but it's still a possibility. And we don't know everything the OP did regarding hardware or software. In cases like this, he may not even remember them all.

Did you try booting up in safe mode and see if the problem persists?

Also, try restoring to a point before this problem.

That's the reason I put in that second sentence.

Since it is happening in win7 as well as Xp is does not seem an OS issue Try to load BIOS defaults & see

also try these

Windows XP restarts when you try to shut down your computer
Windows XP restarts unexpectedly or restarts when you shut down the computer

I will try it in safe mode.

But I dont think restoring is possible as I have reinstalled windows many times(for many different problems :)) )
