. Since you decided to reinstall on your own I would like to recommend you wipe your drive first. The "format only" option has the possibiblity of a malware re-infecting your system. By using a drive wipe program you eliminate this possiblity. There are several good programs out there to do this with. The simplest would be Active@killdisk
. It has a basic freeware version of the professional version. The freeware will do quite nicely in your case. Another program which I find more useful is Digital Dolly 1.0
. It has most of the features of Partition Magic, including drive image, format, partition manager, S.M.A.R.T. drive, Drive wipes (including Quick, DoD, and Gutman), and a few more. The difference is KillDisk will run from a floppy, but it is not as versital as Digital Dolly.
Whatever you go with I would at least Quick wipe the drive if you have malware on it.
