computer mysteriously shuts off (kind of)

[progman]

okay, i recently built an abit k7v with a thunderbird 750. hmm, what else. 300 watt powersupply. anyhow, it pseudo-shuts off fairly frequently...the hard drive light turns and stays red and then i have to restart. All mobo drivers and other obvious stuff i taken care of. I guess that isn't much to go on.

Most likely a heat problem. Does it usually happen after you use it for a while?

[progman]

yes, generally after a bit of time. i have a big fatty heatsink...hmmm. it usually runs slightly over 100 fahrenheit i believe.

[hapoo]

well your cpu isn't the only thing that can over heat, so can your ram, your hard drive and a bunch of other parts.

[progman]

hmm, i didn't think about that. perhaps i'll get a case fan and then see how things go.

[hapoo]

first go through your case while the computer is running and touch the hard drive and the cpu heatsink, check to see if they are too hot.

If you have the Si SOft sandra program run each hardware device sepertly in the burn in test.This will load the items and heat them up when an item locks you up there is your problem.If none of the hardware locks you up it may be a software issue.

Also make sure no irq is shared with your video card this will cause eratic lock ups

Make sure it is not a POS power supply, that also causes random lock ups. I got me a sparkle 400 so I won't have to worry about power for a while.

progman, maybe im reading this wrong but are you saying you dont have any case fans?

[The Happy Squirrel]

are you networked in any way?
if so it may be a trojan virus <such as backorrifac>

it sounds like you ahve your heat under control, or at least think you do

this is prob not the case but it may be an option to keep in mind
that is fi you are netwroked

[Cheesypuff]

Have you ever thought of it being on standby?

[Y2J]

for wahtever reason this happened to me too.
I thought it was heat, put a big ass fan next to the open case, and it didnt solve anything. Then I put ZoneAlarm (free firewall) up and it solved my problem

Disable all the power management garbage. It my be going to "sleep" and not waking up.
