I have a fairly new P4 Intel original Mobo based system, which worked fine for 2 months, though i had to re-install Windows quite sometimes till i got a good UPS.. Now, suddenly, the OS crashed, and I get an error "DMBOOT.sys is corrupted, press any key to restart" when ever I try to re-install windows. I've even done a Low Level Formatting of my HDD and tried using 2 different Win XP cds.. but can't get to work..!! pls help me ASAP..! help appreciated..!
