I upgraded my PC from P-4 1.5 to P-4 2.26, new box and motherboard, from Intel board to MSI 845PE, loaded all drivers for new board, now DVD will not play using WinDVD or Power DVD, only a shareware program plays DVDs. HP Memories Disk software will not find CDRW or DVD-RW, even though it is an HP DVD writer. Roxio Platinum 5 works fine with both devices. I have uninstalled and reinstalled all of these programs. Also, WinMedia Player 9.0 will not play any audio CD's but the old Win CD player works fine and plays any audio CD. BIOS recognized all devices properly. I have added all Win98 patches to date. HP tech support was of no use. A little help?
