For some reasons my Windows XP desktop is freezing after maybe half and hour of use ( just normal usage such as browsing the internet, no fanciful gaming). This is already happening 3 times today; yesterday was OK.
I checked my system log after my machine restarted, there was no record of exception, no record of error, as if everything was fine.
When the machine freezes, everything becomes irresponsive; mouse can't move, keyboard doesn't work, the clock at the bottom left of the screen simply doesn't moving forward, it's as if the passage of time stops completely for the machine. The hard disk isn't busy also, as the hard disk light near the power on/off button isn't blinking.
The funny thing is when I force-restarted my machine, I was not prompted with "scanning the disk for bad sectors" blue screen-- which is fairly typical if this is a hard disk problem.
Any idea what can be the problem? Registry? Bad sectors? Memory problem? Some of the yahoo answers suggest that registry corruption is the problem here. But I've been extra careful in installing and uninstalling software, not to mention that prior to this incident I didn't install anything on my machine.
Edit: I have scanned my C drive and it has 12 kB of bad sectors. Could this be the reason?
