Scrolling makes computer turn itself off

ege02

So for the past two days I've had this problem where scrolling up or down in Firefox or IE makes the computer turn itself off.

I can use the mouse-wheel just fine, but that will sometimes turn it off too.

I opened the case to take a look inside, and noticed a thin noise coming from somewhere. I don't know how to explain this noise, but it gets more intense when I am scrolling and then the computer shuts itself.

Two things:

- recently I got a new graphics card, a low-profile geforce 6200. it's at 52 degrees when idle, so im pretty sure it's not overheating like my old card.
- i leave my computer on at night, so it's on 24/7

Any ideas?

Is that 52° C or 52° F? If Celsius, it is probably overheating.

Also, your computer might be blue-screening. In XP, by default, the computer merely reboots.

It doesn't reboot. It shuts itself off. Like, I have to actually turn off the power-supplies switch behind the computer and turn it back on before I can turn the computer itself on.

Also, here is a pic of the temperature monitor.

Sign that your power supply is either too weak, or it is dying. Sounds like the scrolling has less to do with it and more of just bad timing.

If you have to switching the PS off using the rear rocker switch, it means the PS's internal breaker is being thrown, probably from too much power consumption. The only correlation between scrolling and the overload could possibly be the Graphics card drawing more power while drawing the new screens (because of the scrolling).

Also that seems like a rediculously high threshold for GPU temp. I'm not all that familiar with thermal characteristics of GPU's, but most don't like temps above 55 celcius, and anything about 75 has the potential to crack a CPU.

For reference, 100 celcius is the boiling point of water.

What the OP posted is actually pretty standard for a modern GeForce part. My 7900GT idles at 51C, and has a slowdown threshold of 125C. That's the default slowdown value, I haven't modified it any, so that's what gets set when you first install the Nvidia drivers. I can only assume that the parts have been designed with high heat tolerance in mind, moreso than modern CPUs.

This is accurate. 52 Celsius is perfectly acceptable for an nVidia card. I wouldn't worry unless it's hitting above 80.

I'd find some motherboard software to try monitoring the Power supply voltages to see if they're dipping too low (or spiking).

Maybe you did something when you installed the card that would cause a short or something?

Try putting the old card back in, as maybe the new one is defective.

If not then I guess it has to be the PSU, though it's very strange, as I think the 6200 isn't very power-hungry...



The noise I would guess to come from capacitors or coils, and is somewhat normal for cheaper components and shouldn't be a cause for concern.

PSU

on my older computer you can definitely hear a difference in the electricity when you are scrolling with the mouse wheel and not during anything else in particular ...


... if its that noticeable there, I wouldnt be surprised it's putting some kind of strain on the PSU that is causing it to flip off
