Like some people, I resist asking for help. But this problem is haunting me. So I humbly ask for help. Here are the facts, as I see them.
Machine: Dimension 4100, 1.1 mhz, 512 mb Ram, XP Pro SP2, latest updates/drivers.
Problem: CPU freeze/unfreeze
Specifics: Whenever this starts, it ALWAYS goes this way---5 second freeze, 30 seconds unfreeze (CPU runs normally), then 10 second freeze, then 50 second unfreeze (runs normally); then it returns to the 5-sec, 30-sec, 10-sec, 50-sec cycle and loops. Only way to remove problem is to shutdown; but the very last phase of shutdown does not complete, requiring what we retired IBMers called the BRS solution (Big Red Switch to power off the offending hardware ..ha). Subsequent re-starting computer is normal and problem not present until it decides to manifest (see details below)
History: When this first started (8-10 months ago), I searched MS Knowledge Base and found the identical problem occurs when using Iomega Parallel Port Disk Drive. I immediately removed that hardware and software and never used it again. And the problem disappeared. BUT some months after this, the problem reoccurred! Wow! Went back to MS KB to find the original article…none to be found!?! Continue to live with problem; but decided to seek help on this forum. Thanks to anyone with suggestions.
Details: Seems to start after a long idle period (more than 10-15 minutes), but not always. Probably not related to internet as it does occur when cable modem is disconnected. Not related to Firefox as happens with Firefox uninstalled. Can be connected to internet and doing local processing (no net browsing) and have not noticed freezing. Interesting note: After a CPU start and run for some time without problem, I create a Restore Point. Then later in same startup or a later re-boot, when the problem does manifest, I can execute that previous Restore Point and the problem does go away. (but I can loose some other things that way). Seems that something gets “added to the System Registry and that “something is initiating this freeze problem. I don’t know what else to try, except to ask this very knowledgeable community. THANKS. :cheesy:
PS Forgot to say that I regularly use 5 spyware programs and the antivirus portion of ZoneAlarm Security Suite. Always finding stuff to remove, but doesn't seem related to problem.
