Windows 7: Windows 7 Random Reboots no BSoD

I am currently having a problem with a computer I built. The computer when you have it in normal startup or selective startup will reboot itself when you are watching videos online. The reboot will happen quicker in IE 8 then Firefox 3.6 but will do it in both. There is no BSoD on reboot. I have deselected the automatic reboot selection in case of a BSoD just in case there is one. In the event viewer it just says the computer rebooted but doesn't have an error saying why it rebooted. I have checked the temps and they are with in spec.

If I go in safe mode it will not reboot itself. This leads me to believe it is a driver/software problem. I have checked the memory with memtest86+ 4.10 and it passes. I have ran sfc and chkdsk and both found no problems. I have downloaded the latest drivers for the motherboard and video card. The computer will not reboot itself if it is left idle. It only reboots when you use the internet or internet video.

Any help would be greatly appreciated,
Ben

We would be more useful if we had the actual DMp file usually created when the computer crashes. Use these to find it (if there is one) and upload it. http://www.sevenforums.com/crash-loc...d-problem.html

Thats one of the problems I am running into. There is no dump file created when it reboots. There is no log created in event viewer other then the system rebooted. This is what is making it so hard to figure out.

Check your PSU.

I second that

You might want to go to Resplendence and read about and DL the free WhoCrashed which is an automated crash dump analyzer. I find that most of the time it will accurately report faulty drivers - better than EV and on par with a lengthy dmp file analysis - without all of the enigmatic computer speak.

I third the power supply comment, it's the most likely cause is a matter of fact.

Sorry, but unless I'm mistaken, WhoCrashedIt won't work if there is no dmp.

Monk, he doesnt have DMP's and who crashed, while a good entry level program oftem gives incomplete analysis

Two points:

1. WhoCrashed is, indeed, a great entry-level app;

2. I completely forgot about the lack of a dmp file.

It's no excuse but I claim age!
