While this could be a software problem, The most probable culprit is a bad memory chip, you can google "Microsoft memory tester" and download the disk image from microsoft and burn to a cd to test the memory yourself.

I have also seen a lot of dells do this due to faulty capacitors on the motherboard, a quick visual inspection (just open er up and look closely at all the capacitors) should be able to give you an idea if this is the case.

You will see bulging or leaking capacitors if this is tha case, which would require replacing the motherboard in most cases.

You may want to consider bringing the PC in to a local repair shop if you are still unable to diagnose the problem yourself as these kinds of problems can be difficult for the average user to diagnose.

Check the event viewer to see if its spitting out a Critical error or warning. This might help you further troubleshoot why it keeps rebooting.

Have been using same WR680g Motorola Router for 3 years. Without warning, the wireless network went down. None of three different laptops are able to detect the network, but can detect other nearby...


Have you tried to reset your router? Reboot doesn't reset the router so try the reset method.

Waiting clarification, don't hesitate to post.

Thanks and regards

System reboots with no warning


Plug a desklamp into the same power point and note whether it flickers at the same time as the reset. If so, you have a power problem. I had a similar problem a while back, discovered the fuse in my household power box was faulty. Replacing the ceramic fuseholder fixed my problem.

This may sound silly, but check the power cord is plugged in hard to the socket at each end. I once made a service call to a computer which wasn't plugged in correctly, and was resetting.

Next most likely cause is the power supply box in the PC itself.

try booting in safe mode by tapping F8 key on your keyboard to go to advanced option, select safe mode, and log on , if it boot up without rebooting itself , scan your pc for spyware / virus do a disc error check as well by right clicking on the local c drive, property, and click tool tab and run the check. if it reboot in safe mode, you have a bad sector on your drive , and need to replace the hard disk

DeskTop PC Rebooting


On a pc this old the capacitors start to dry up. If it's that then it's time to buy a new pc.
Simple test: try going in the BIOS. If (by miracle) you can, change the boot order and put the cd first. Then boot from a Linux Live-CD like http://pclinuxos.com/
If that works then Windows was completely corrupted by malware. Reinstall and next time use a better antivirus.

Laptop switches off without warning


Take a look at the event viewer (Start -> Run -> type "eventvwr" and hit OK) and see if there are any STOP errors right before or right after the reboot time. The machine is probably set to automatically restart after a blue screen STOP error (aka "Blue Screen of Death", or BSOD), but that's making it reboot too quickly for you to see the actual error. Post a new problem with the STOP error code and we can help you out further!

Reboots without warning


Spyware and temp file overload usually are to blame here.

Look and install these two applications:
ccleaner (www.ccleaner.com)
Spy-Bot Seek and Destroy www.majorgeeks.com

Make sure to close all programs specially anti-virus programs before you install them. Then run them in SAFE MODE.

How to enter safe mode:
Reboot your PC and RIGHT AFTER your PC startup BIOS logo and before Windows kicks in tap the F8 key and a Startup Menu should appear, use your arrow keys to select SAFE MODE and run the above applications. Clean any temp files and clear out any spyware.

Hope That Helps!
