Laptop Won't boot - keeps rebooting!?

Question

I have a 2 year old laptop (compaq presario) and I put it into hibernate. When I came back later to start the computer it began booting then half way through just restarted. It just keeps going in this cycle of rebooting and I can not get windows to boot! I tried safe mode, last known config and normal boot with the same problem. Please can you help! THANKS!

Answer 1

I had that problem b4, and i installed an antivirus software and the problem got resolved, How to install if you can login?

You need to have your Bootable Operating System Disk e.g Bootable Windows XP Disk, you put it in the CD Drive, you restart, depending on your mechine when it boots go to the SIMOS Setup(you press F2 and to some motherboard you press delete). boot from CD ROM Drive. from there if it's XP, it will give you this options:
1. To Install ...... Press Enter
2. To repair ..... Press R
3. To escape/Cancel ...............

Please select the second option and it will take you to the dos prompt or a bleck screen saying choose the directory to login, you select it, after that you put an Antivirus Disk in CD Drive, if it is represented by D, from from the dos window type in D : and press enter if the name of the antivirus is setup.exe and is inside the folder/directory setup, you need to type cd setup to move to the setup folder the type setup.exe, it will start setting up the software. Hope this helps

Answer 2

first; to get it to quit restarting so you can diagnose the problem --- go back into that screen where you have the choice of Safe Mode, last good configuration, etc. and there'll be an option there to disable the automatic restart upon failure.

OS could have been messed up. If Win XP, try to repair following this:
