Random shutoffs/reboots

Recommended Posts

Hello,

 

Been having strange things going on... Scenario #1: Press power button, computer powers up, Windows XP boots up. It detects new hardware (variious, printer, digicam, etc) and the New Hardware Wizard appears. After that's on-screen for a few seconds, the computer reboots or shuts off completely. It may do this a few times, and then be fine.

 

Other times, you press the power button, the system powers up, and 4-10 seconds later, just turns back off again.

 

Still other times, you press the power button, fans spin up, BIOS never beeps, video never initializes and it just sits like that until power is removed and then it works fine the next attempt.

 

Any thoughts anyone? Thanks...

 

Add'l Spec:

TurboLink ATX-CW500P4 500W PSU

I suggest you find a way to test whether the PSU has stabile rails or not. It could be that the system is constantly underpowered, or that you're experiencing serious fluctuating. Fluctuating might not immediately shut down the system, but it might still do a lot of harm both to the processes being run and to the hardware.

 

Have you had these problems from the very start?

 

Start to troubleshoot the PSU; according to your sig it's the only obvious weak link.

 

When you finally identify the cause of the problem I suggest you do a fresh installation of the OS anyway, since it might have become corrupted.

hmm interesting.

 

I guess I need to go to the bios an check it.

 

 

Meantime intersting developement currently I have on thing of ram in and unplugged one of my drives with no USB ports in.

 

Everything is working fine.

 

Did 8 reboots no problem, tried to reboot with usb2 in problem.

 

Will check ram voltage.

 

I'm starting to get the feeling that I have a bad board that doesn't like anything plugged on on a boot.

from http://www.dfi-street.com/forum/showthread...79&page=2&pp=15

 

I had a hell of a time with blue screen IRQ_NOT_LESS_OR_EQUAL_TO http.sys (REBOOTING) When I installed XPsp2. Just at random for no reason what so ever... I found out its some conflict with the NF4 network adapter and some service in sp2 for plug n play network devices. I disabled the service and uninstalled the Nvidia network/firewall software crap and it's fine... just an idea

 

SSDP Discovery Service

Completely stable since solving this issue 10 dreadful hours after install. I read microsoft did some tinkering with the ssdp service for sp2, but i can not find the source at the moment...

Wow.

 

I just uninstalled that Nvidia network/firewall you were talking about.

 

 

6 reboots in a row of success. No more reboots. (still with one memory stick and no optical drives)

 

Now I will try with memory and drives back in. You might have been my savior.

 

I am going to upgrade PSU soon to a Antec TruePower 2 550

Any comments on that while were at it, great reviews.
