PC went thru brownouts w/o AVR and now shuts down regularly

by ajseim / July 3, 2007 2:45 AM PDT

We recently bought a reformatted, used PC, a pentium 3 w/996 MHZ and 320 RAM. The computer was working fine until a couple of brownouts from storms. Now, when the computer heats up, it will shutdown automatically without warning, as if someone pulled the plug. We checked all the usual items, wires, cords, wall jacks and all are ok. We removed the cover and saw that the fans were working. Then we put a fan blowing on the computer as well. However, the problem persists. Any suggestions?

What parts can we replace?

Since you've cleaned the heatsinks, reseated all cards and RAM it's time to consider it needs some new parts.

A Pentium 3 is beyond it's expected lifespan so it may be best just to return it.

Do you think if we added an AVR that the problem would be resolved?

So you added a German nuclear reactor?

In reply to: power

I decided to invest in a voltage regulator, based on what I've read from the CNET forum searching I've done. In the Philippines, where we are, there have been frequent brownouts due to stormy weather. The lights have flickered frequently and I think that it is the power fluctuations that are causing the computer to shut down. We'll see if that resolves the problem. My concern is if the computer has suffered some damage. We will see. I may need to return the computer or have the power supply changed.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
