today i bought a new dvd drive, becouse my old one was very naughty and wouldn't do it's job properly. i also got myself a new gpu.(ati 5770). so when i changed my gpu's and instaled the new dvd drive (sony optiarc ad 5200a ata) a problem ocured. every time i turn my pc on i have to wait around 60 seconds to see the boot screen. i turn on the power and the drive makes a sound like it's reading a dvd (although it's empty), and it lasts about a minute before i hear the beep sound and the bios screen apears. i tried putting the old dvd drive back in, but he suffers the same illnes now. maybe it has something to do with the new gpu, i also switched power cables form the old one(geforce 8800gts) becouse it died on me a week ago, just to be sure. i doubt it's the psu becouse it's powerfull enough form my system( seasonic 650w). my motherboard is asus p5n32-e sli plus. the dvd drive is ide. the cpu is oc'ed. i tried switching the jumpers on the back of the drive to all 3 positions but with no result. if anybody had similar problems i would apriciate some help.
