kk.. soo heres what happened.. my XP seems to have attempted suicide and almost got there.. heres the events prior to the crash: i was using PerfectDisk 7.0 to defrag my drives and i did a defrag on start up of the System Files and the Page File. so all worked like a charm.. booted up to windows n everything.. in windows i did another defrag.. jus to make sure so it worked and everythings in la la land.. next i use windows Disk Cleanup Utility to clean up a buncha junk. and i checked the boxes on anything that didnt have a 0kb so that works.. then i go click on Start. and all progs.. it almost showed up but disappeared so i thot i misclicked.. then i go back into again and eveerrrything i mean everything in the all programs menu is gone cept for accesories and some random folders.. but even in those folders it was EMPTY.. the only thing i found left was perfectdisk in system tools. so i restart and found my XP unbootable.. it says some hd.dll or somethin h cannot be found in system32.. asked me to put it back n restart.. well i couldnt cuz i cant boot.. lol so i jus reinstalled xp.. i jus wanna know what could have caused this to happen so i can avoid it in the future. thanks!
