I am running Windows XP Pro, Intel Celeron 2.4 GHz CPU, and 2 Gb RAM. My computer has recently started randomly shutting down and won't restart until I unplug the power cord and plug it back in. All fans are running. My CPU temp is 40C. I have replaced the CMOS battery and the power supply. It is still doing the same thing. Does anybody have any idea why this is happening?

Hi, You need to look at the motherboard and video card if used.

Look to see if there are any bulging or leaking capacitors. They are one possible cause of the problem you are describing.

Go to www.badcaps.net and look on the right hand side where it says Examples of bad capacitors: for examples.

Good Luck

I will take a look. I am a nurse and work night shift. I work tonite, so it will be tomorrow before I can look. What else might be the cause? Could a software problem cause this? I installed Norton 360 Version 6 and Microsoft Office 2010. I have been usint Norton 360 and Office 2000 without any problems at all.

Thanks
TC

Since you have already replaced the power supply I would say your mobo is going out. What wattage power supply did you put in?

Just got in from work. I replaced it with the same one I've always had, 300W. This is the first time I've had this problem. Got to get a little rest before checking the caps. It's just strange to me that the power button won't do anything until thepower cord isunplugged for about 5 seconds. Then, it boots just fine.

I couldn't see anything abnormal with any of the caps. Could some be bad without showing any signs? Any other suggestions?

Unfortunately yes they can die with no signs.

It is sounding like the motherboard is bad.

I would back up anything I didn't want to loose.

IN NJ where I am you can get Pentium 4 used computers that are faster for around $99.

Checking the circulars every Sunday.

I just took a look at the Best Buy weekly sales and they had a HP laptop for #329 and a Dell laptop for $349. The problem with them is the high pressure to buy extended waranties and GS services. I just keep saying NO!

Good Luck
Roger

trucol, if you can find your motherboard model I will find something that will work for you.

Was this a pre-built system, or something you built yourself?
