lately my computer freezes too many times. i run memtest86+, mhdd, and WD tool. memtest86+ and the WD tool didn't find any errors. mhdd found 15 green delays (<150ms) and 1 brown delay (<500ms) but no bad sector. what my next step should be? should i use the erase command or Scan+remap?

I think your problem is not witheet the harddisk, but windows.
Try reinstalling it (after backup)

backup first if you have important data into before action.

Id suggest cloning ur drive onto a new one and sending the old drive for the warranty return ( if u have it ). If clone comes through clean and windows still screwed - run a chkdsk /f /r if still bad - backup and reinstall windows =)

i already backup the important data. should i reinstall windows?

Yes, do a clean install and then restore your data.
If you still have problems after that its probably the disk.

its like this , if a windows component falls onto the slow responding sector - it can get all whacky again. I use PC3k for this things , but i am thinking that MHDD when it formats the drive is capable of taping the slow sectors to be realocated. After that reinstall the windows.
