Suspected Hardware Problem

by AsianPrincess2586 / March 14, 2007 4:21 AM PDT

Information About My Computer:
HP Pavilion 533w
Windows XP Home Edition
60 GB hard drive
2 GB Intel Celeron CPU
Uncertain about Motherboard
256 MB RAM
Software-based Nvidia Video Card

My computer will soon be 4 and 1/2 years old and it has never had a single problem during this time. I have periodically removed any dust that has accumulated inside and the only thing that I have had to do is the occasional OS reinstall.

Last week, my computer started doing something unusual that it has never done before. I would be doing something or the computer would be in sleep mode and the computer would just turn/shut off without any warning. It was the same as if you had literally reached over, held the power button in, and turned the computer off that way.

Each time this happened, the power light on the back of the computer would remain on, but pushing the power button to restart the computer did nothing. The only way to restart the computer was to disconnect all electrical power, then reconnect the power and the computer would restart.

The first few times this happened, I was not certain what the problem was since it was so random. Within a couple of days the computer was doing it more and more. I started running diagnostic programs and the check disk features on the computer. The diagnostic programs were able to run long enough to show that the CPU and hard drive were fine. I scheduled the check disk feature for the next start up but the computer was not able to run long enough to finish before shutting off. Each time the computer has been able to only stay on for shorter and shorter amounts of time before shutting off.

Through all of this, the OS has appeared to be working absolutely fine without any problems or crashes.

At this point, I have the computer completely unhooked as a precaution that further attempts may cause damage to the internal components. Does anyone have any suggestions for what the problem might be?

I really want to get my computer fixed and not have to give up on it. Any help is greatly appreciated.

How long has it been since you dusted out the internals and checked the fans?

With the loss of power, I was wondering if that might be the problem but I have little experience with the hardware side of computers...

Dusting Out Internals

It has been around 5 weeks ago since I cleaned the dust out and as far as I know the fans are still working without problem...

Try leaving the cover off the case.

The Samsung RF23M8090SG

One of the best French door fridges we've tested

A good-looking fridge with useful features like an auto-filling water pitcher and a temperature-adjustable "FlexZone" drawer. It was a near-flawless performer in our cooling tests.
