Hi all nebwie here, Although I searched the board I couldn't find the answer to my problem. I recently installed a PCI IDE Card so that i could add a 3rd HDD to my system. After installing this card, the system boots "through" the 3rd HDD (hooked to the card) instead of the from the primary HDD (hooked to the MB) that contains the OS (Win XP). The system works okay, but it does take longer to boot, and I regulary get prompts stating that the applications aren't responding (then it takes about 15 - 20 seconds for the app to "kick back in"). I've gone into the MB BIOS and reset the primary to the the original HDD, but when I do that, the system won't boot up. Any s****tions are appreciated. Here's the stats: WIN XP (home); ASUS A7V333-X MB; 1.5 GB RAM; WD 80GB (Primary w/OS Installed); WD 150GB (Secondary); Max 300GB (on PCI IDE Card) Thanks.
