On & Off by itself

Nov 5, 2004 10:57PM PST

I'm running a self built 1 gig CPU with 1/2 gig of memory CA 63 sn board with C:, D: and F: for video editing . 98SE , Norton AV is up to date . Sometimes change OS (in a drawer) to Win2K for DVD authoring. All of a sudden it goes on and off. If I'm working it doesn't happen but if I leave it alone for a while it will go black screen and reboot . Happened in 2K once I think, but happens a lot now in 98SE. External high volume fan and the CPU runs at 82 degrees C. On reboot scan disk runs...Have redone BIOS 3 times power usage has been reset , screen saver and hibernate are shut off ACPI has been toggled, tried everything I can think of . Anyone ever seen this?
Thanks,

Re: On & Off by itself at 82 degrees C CPU.

That's too hot. Remove the case cover and start finding out why it's so hot. You may need to get a monster sized CPU cooler or the CPU has already fried and is doing the usual death throes.

Is to HOT. Make shore the wires that connect to the fans are atached, and the fans are running.

Every one is in agreement that your system is too hot.

System such as yours should have a fan in the front blowing in, one on the back blowing out, on the video card and on the H/D. Others may suggest a fan that blows out a PCI slot.

A Goole search on "fan tunnels for computers" turned up some intersting ideas. One I liked and use is cutting out the bottom of an 8oz short plastic cup. You then glue the large end over the front fan (80mm). This increases the wind force and directs it towards the AGP/PCI slots. First system I tried it on reduced the rear fan output temp by 10 degs.

Just for fun, it's not unusual for us to have to modify poorly designed cases to get the heat out.

My prime suspect is a cheapy CPU heatsink/fan. Or one that was designed "for up to 2.4GHz CPUs" and they have a 2.4 GHz CPU.

DOH! That was 86 degrees F. Never figured out what was wrong but now it's behaving, Is this really a science?
Thanks
