|Because PC was at times slowing to a crawl a complete reinstall of WIN XP was completed in Jan 2010. This appeared to be successful. However intermittent hesitations and unresponsive programs events continued and are worse now (August 2010). |
When problem exists every command can take 1 minute or more to execute. Some or all windows may go to blank white, or whole screen to black for some time. Program may show as "Not responding" for a while and then return. If left for some time PC response may or may not return to normal. I have had the screen go black and stop. Two attempts to reboot were required to reboot.
All attempts to isolate the problem have failed. I have tested the HDD (Health is %98%, Performance is 100%).
Replugging RAM and HDD data cables appeared to improve matters the first time this was done, but did not change results on subsequent repeats. The Events Viewer logs sometimes show 2 System errors: (9 and 51), "The device, \Device\Ide\IdePort0, did not respond within the timeout period", and "An error was detected on device \Device\Harddisk0\D during a paging operation."
I run AVG9 AV(free), and clean registry frequently. I do not suspect software.
I suspect a motherboard fault. How can I confirm that?
PC is AMD 2400, 2,4GHz, 480MB RAM, HDD 40GB (3.9GB spare on C:, 21GB on D:)
