When programs behave incontrollable, display frozen, harddisk kept spinning, even Ctrl+Alt+Del wouldn't help, then I turned off the power. But disaster followed, Windows couldn't restart, it just rebooted again and again.
I tried Anti-virus boot disk program, XP installation Recover Option, etc., nothing could help, even the OEM's reinstallation disk just erased everything but didn't start reinstallation. The harddisk kept running and occasionly emitted some strange noise.
Finally by chance I tried a floppy boot disk software called MadBoot, it contained a Low Level Format program but was sluggishly slow. It ran for a whole day only to format a little bit of the whole Volume (57G). It took me another week to try all sort of things before I can reinstall Windows. Although now I am done, besides losing everything my running speed is only half of the original. I have used XP's Disk Utility to check and fix but it does little help and I have contacted the Manufacturer Agent but the respond was very inefficient that I have to bring the PC to them for analysis and it takes a week or so at least.
Can you recommend some good softwares for me to check and fix this problem? It is quite strange that I did not get any error code if it was a Hardware failure.
