constant restart problem

Hello, I need help. My windows xp computer keeps restarting itself constantly. I will turn the computer on and as soon as I log in my account for xp, the computer will restart. It will continue to restart until, after many restarts, it will finally shut down completely only to turn back on if I leave the power cord unpluged for a few hours. Sometimes it will even begin restarting even if I don't log in, it will constantly restart from the xp login screen. I'm not sure what is causing the problem and any information will help, thank you.

 

Some possible reasons:

1.) Malware/Viruses - has your PC been scanned for malware recently?

2.) Hardware faults - Bad memory (RAM) (Download "memtest", burn to CD and test upon boot up)
Bad power supply (somewhat difficult to test, swap with a good unit if possible)
Bad motherboard or corrupt BIOS (does your time/day settings in XP change?)

3.) Windows configuration problem or driver(s) issue.

To more/less rule out Windows as the issue, try booting in safe mode. Does it restart then?

 

It never gives me the option of starting in safe mode, every restart just begins to load the windows xp. Also I come to realize that my computer will work at some moments. If by the lucky chance, my desktop opens up and files start to load, the computer will then work only if I am fast enough to shut down some unecessary programs. This seems to be a memory problem. Any methods of gaining more memory?

 

Seconds after your computer boots up, hit "F8 several times." You should then be given the option to go into safe mode. Let me know if that works.

 

My guess is a virus. Try the Safe Mode suggestion, and if it doesn't restart itself, I'm right. If it restarts, it's something else. Post the results once you've done this.

 

This first time I tried safe mode it was unable to start at all and then the next time it opened but as soon as my desktop came up, the computer restarted itself again. Another thing ive come to notice is that, if I am able to get my computer on and running it will restart as soon as a open my documents, causing the explorer to use 100 percent of the computer memory and usage. I'm not sure if this helps show the solution but I'm just pointing out more details.

 

From the description you provided it sounds like a power supply problem. It would also help if you post your system specs, To include Make and model System if Big Box, or same info for the following if custom or home built, Mother Board (including Revision number), Processor (Exact Model Number), Ram, Video Card, Hdd(s), Optical Drive(s), Power Supply Manufacturer Model, Wattage and Amperage on the +12V Rails, OS, and any other peripherals installed on the motherboard.

 

Good evening, my computer will not get past thein touch with tomorrow toshiba and the other page that tries to let me restart my computer in safe mode,safe mode with networking, safe mode with command prompt, last known good confiuration, and start windows normally. It will not do none of the above . MY COMPUTER IS A TOSHIBA SATELLITE AND THE MODEL # IS 2805-S302.
