A couple of days ago I decided to take my computer tower to school. After I got there (carried it on the bus :P) and set it up it wouldn't boot (said it "could not load OS"). I tried starting in save mode but it would hang while trying to load the system files (specifically on the file 'agp440.sys').
When I got back home I tried the Microsoft bug fix suggestion for the 'agp440.sys' (http://support.microsoft.com/default...b;en-us;324764
) problem but it didn't help (safe mode just hung up on a different .sys file). I was suspecting some OS files got currupted.
Then I tried booting from the WinXP SP2 CD, pressed 'R' and then tried to run chkdsk /p and /r which took A WHILE (at first it was fast, but after getting to about 70% it went back to 50% and then took about 1.5hrs to finish).
I then reinstalled Windows XP SP2. It kinda worked...Windows started up fine, but it was VERY VERY SLOWWW (the first time it started it took about 20sec for the start menu to open after it was clicked). I restarted, it was better but it was still SLOW (the cursor would jump, took a while to open any program, etc). I quickly started backing up my data to my other HD, which also was SLOWW (transferring a 700MB file to my other HD took about 35min!). Burning CD's and DVD's was also 10 times slower (took 2hrs to burn a DVD which usually takes 15min).
I tried running hardware diagnostics tools such as PowerMax (both my HD's are Maxtor), Tuff-Lite (full hardware system tests) but they claimed all was fine!
I ran Defrag which found the HD to be rather fragmented (didn't defrag for 5 months). To Defrag the 80GB drive took about 8hrs! There was no improvement in symptoms afterwards.
I tried running ScanDisk, which went through the first 3 phases fine but was VERY slow on phase '4 out of 5' (checking file data)...it took about 2hrs to get to 13% at which point I gave up and stopped it.
Currently Iím running 'HDD Regenerator v1.41' which does a physical surface scan (and repair) for bad sectors. Currently it went through the first 20GB but found no bad sectors!
I'm running out of ideas!!!
Is my HD done for?? Would doing a clean format fix this? And even if that does work would it be dangerous to store data on it because it's 'unstable'??
