Computer randomly shuts down, w/o notice

[boomdart]

My sister's computer randomly shuts down w/o notice... Virus scanners don't find anything, and all the spyware is removed from her computer. It's not like the worm that was out; which gave you 30 seconds or whatever, it just shuts down.

What could the virus possibly be? It happens on my mom's computer as well... :/ And both computers are on a network...with two others, but neither of the other two are infected.

My computer doesn't have it because I live at the dorm >

What makes you think it's a virus rather than a loose wire in the power supply or something?

Are they on a UPS that is failing?

1. Something overheating (cpu, ps, ect)
2. Bad Memory
3. Bad HD or Corrupt data

Make sure the fans on the CPU are free of dust/debris and are spinning freely. Same for other fans.

People who are mentioning hardware.....it is happening on two computers. Do you think both of them simultaneously had hardware failures that are causing the same strange behavior? It doesn't sound likely to me, unless it's overheating or something but even then it doesn't seem likely at all.

Two computers in the same house, turning off at the same time, for apparently no reason, and you think it's something other than a power problem?

computer is just tired

 

[calboy98]

is it going through the shutdown process or just powering off instantly?

You said it could be "loose wire in the power supply or something". I figured you were implying a loose power wire in the power supply of the computer. So both computers have a loose wire? Or were you referring to a loose wire in the power supply of the house?

Other people are putting bad hardware, seems awfully suspicious unless the two computer were made with the same components.

I said "or something", indicating that it could be something other than just a loose wire, but that was my first guess. It could also easily be a lousy power supply to your house.

If they were on the same power strip, maybe the fuse blew?

I leaning towards a brownout, maybe those 2 computers are just more sensitive to voltages. Do they have additional hardware that the 2 that stay up don't have?
