Boot problem - press ctrl+alt+del to restart

I was having some issue when I turned on my pc running Windows XP. I actually didnt write the error message completely. When I turn on the computer, then I am getting a black screen which said to press "ctrl+alt+del" to restart. So I pressed them and it rebooted with the same message. So, I just turned the computer off. After some days, I turned on the computer and it worked properly. I have also scanned the pc and found no infection as well. So, can anyone tell me what could be wrong in this computer? Thanks.

Well, can you try to post the error logs generated in the Event Viewer so that we can troubleshoot it?

Thanks but I am not able to see anything in the logs, there are no error events?

It might be that your pc overheated or the memory ran out and was not able to recover. It could be also possible that the cabling is creating a massive field and zapped your pc or maube a ufo passed over your place.
