First I would like to say I'm new to this form so I hope I'm posting in the right place. I have been having a problem with my computer freezing up. Once this happens the mouse, keyboard, everything is frozen. I have to kill the power to restart the system. No set pattern for freezing, sometime when it has been sitting idle, sometimes while I'm using it. I look it into a repair shop, they went thru it and updates various thing, it was ok for about a week then back to the same problem. Fans are working and I've tried leaving the cover off and sitting a small household fan, i don;t think it is a cooling issue. I have tried disconecting my second harddrive ,floppy drive , both dvd writers and removed all related programs, still the same, tried installing new ram, no help. I do not have a windows xp disc as it was installed when I bought the system.
The only things left are the power supply, video card, motherboard or primary hardrive, or of coarse a softwear issue.
Can anyone help. Keep in mind, I don't know how to go to deep into the program diagnosis area.
When I had a freezing problem on my computer I traced it down to the onboard audio card. Installing a cheap 10.00 PCI soundcard fixed it.
On my computer the cpu was always at 100 percent even with no programs running, once in a while I was encountering audio problems. Also the computer would freeze for no reason and required a reboot. Also don't rule out the video card. If you have an extra video card swap them out for testing.
Software will usually be driver related or maybe too much antispyware software working against each other.
Other things to check is to make sure your hard drives are correctly set to dma.
Also you can do a chkdsk or scandisk on all your partitions. A drive that is corrupted will hang the computer when you try to access it.
