Re: hardware Problem?

Hi Peter, Thank you for your response. PC's specifications are

OS: XP Pro, SP2
Cpu: P4, 1600mhz
Motherboard : ECSP4S5A (5PCI, 1AGP, 1AMR, 2Dimm, 2 DDR DiMM, audio SiS645)
Memory: 512 MB (SDRAM)
BIOS: AMI (11/07/01)
Video Adapter NVIDIA
3D Accelerator Nvidia
HD 40GB

I have been having this problem for quite sometime, that is the reason why I
decided to reinstall OS hoping that it will solve the problem but it has made
no difference. The thing is that the problems I mentioned do not happen on a
certain pattern, there are times when the computer behaves normally, boots up
normally and does not freeze or turn off for a few hours, after a few hours
it will eventually turn off by itself, the time expand till it turns off
varies from 1 hour up to about 5 hours or over. Also another weird behavoir
is that sometimes the CPU usage seems to jump to a high 80 to 90% without any
change of the usage of PC, it appears to be performing lots of processes
while I might just be using word, not downloading or anything extreme, and
sometimes this is the time when it turns off it seems to be overwhelmed by
all the processes it is performing. I have cleaned the computer inside not
too long ago, so it will not be dust. Thank you for your help I really
appreciate it.

Could you post some specs of your machine....otherwise we are just flying

But here are some suggestions.
Overheating can cause shutdown......when was the last time you cleaned the
dust out?
Stop during cold boot but start after can designate a failing power
supply...not enough power to spin up all the devices.
When you reinstalled the OS did you also reinstall the motherboard drivers
for your specific motherboard chipset?? the Video Drivers for your Video
Card??

Hi, I have been having trouble with my computer for sometime now reason
for
which I reformatted and clean installed XP Pro but the problem is still
there. My PC does the following at ramdom and quite frequently:
sometimes
it freezes, other times it just decides to re-boot while I am using it,
other
times it just turns off completely and will not start up again until I
remove
the power supply cable let it sit for a few minutes and replug the cable,
other times at rebooting stops and will not complete boot up. I just don't
know whether it might be a hardware problem and if so which component. My
PC
is 6 years old pentium 4. Please does anyone have any idea as to what it
might be or how to go about finding out the reason for this behavour.
Please help any advice is greatly appreciated
Thank you Elly
