My Windows XP Pro installation has every current Windows Update patch and driver. Here's my problem: When trying to unrar a bunch of files into .cue and .bin files for burning a cd, instead of taking the 2-3 minutes it should take, it takes 90 minutes to decompress. Somehow related to this, when I try to burn any cd, it still works, but that also takes about 90 minutes instead of just 3-7. I was wondering if Intel Application Accelerator could be a possible cause before (as it was the last significant app I remember installing), yet I've not heard of anyone having any real problems with it. I wiped my C drive and did a reinstallation, sans IAA. Everything seemed to work just fine. For a while. I'd not added any non-standard apps and was naturally confused, so I did another rebuild and the very first apps I installed after the Intel Chipset utility (my mobo is an Abit TH7-II RAID) were Winrar 3.9a and the latest Nero. Same problem, but without IAA or any XP patches on the system. Since I use Winrar and Nero frequently for backups, this is unacceptable. If anyone can please help, I'd be most appreciative. Thanks.
