Computer keeps resetting on it's own!!?

[DavidCane]

This has been happening for a couple of months now. My system will be running fine then suddenly reset. It can happen randomly or when the case is knocked. I've stripped it down twice and put it back together just incaes there was a loose connection causing the problem but it's still there.
Could it be that I am asking too much from my power supply?

I have the following pligged into it:

ATX PSU with,
Abit BH6,
CD-Rom
CD-Writer,
SB Live! Drive,
3.5" Floppy Drive,
1 x Hard Drive,
2 fans on CPU(Tennmax)
1 Tennmax fan on V3 3000,
1 Case fan
1 fan under harddisk.

The 1 case fan and the 2 on the CPU are plugged straight into the mtoherboard fan sockets.


Do I need to buy a better PSU? (this one is 1 yr old so it's pre-Athlon, I'm not sure what power rating it is)
This happens wherever I plug the computer in so I've ruled out a dodgy outlet in the wall.


Any help appreciated,

Thanks

A few questions -
what's the rating on that power supply - 200 Watts, possibly 230 Watts?
You'll want something rated for 250 watts or even 300 if you can spare the change....

I've got a power supply on my older system that actually has a supply out on which I have my monitor and speaker power feed. It's a 250 and does the trick because I'm only running a AMD 266 on it . If you have something like that and you've got the monitor plugged into it - go for a 300 watt unit.

next - does that mobo have a temperature sensor on it - the sensor may be going bad, or may not be getting enough ventilation and then shuts the system down. If your system has been up for a while each time it mysteriously shuts off - then this is a good possible suspect.

Do you have the freedom to run your system without the case on it? ( I.E. children , cats, birds, or lots of dust about = no )

The case is largely cosmetic and doesn't really serve any purpose other than to keep the user from shocking himself, and keeping the components save from outside contact. - Oh yeah - it's good to stack disks and manuals on top of.... http://www.sysopt.com/forum/wink.gif otherwise - run without the case and any temperature issue should resolve itself.

Had similar problem happening to a guy I know. Turned out the voltage switch was set at 220 instead of 110 on his power supply. No problems since. Silly, but hey that's what was wrong.

Well I can tell you that the PSU has an output of 250W max. I can tell you this cos it's in in my hand now.

I remembered that I had another ATX case + PSU in the garage (the case is wrecked but the PSU is fine) so I've swapped them over, and so far so good.

If it happens again I'll call back.
Also, the PSU that was playing up had less outputs than the old one I'm using now. Could that make a difference?

Thanks anyway
