I loaded up my sony vaio vgn-nr21m the other day (operating system vista) and a windows defender message came up saying it had detected malware and then the computer just crashed...wouldnt do anything so i had to pull the battery. Since then when i start the computer it loads up a windows error recovery screen with two options of launch startup repair and start windows normally neither of which will work, occasionally it will load through to a windows boot manager screen advising the use of the recovery disc but with an error message saying that the boot selection failed because a required device is inaccessible. I seem to have lost my recovery discs (which i am kicking myself about) so. Ordered a hirens boot cd from ebay to try and get it going, it reads the disc fine and starts to load up mini windows xp hut then crashes half way through loading.
I decided to try and perform a full system restore to wipe everything and start fresh, but when i press f10 as the computer loads a message stating 'a disk read error occurred, press ctrl + alt + del to restart'
Im wondering if the malware has caused a hard drive failure and if its worth trying to repair, has anyone had this before or any help that you could give me would be great.
