I have recently built a PC from ground up and it has experienced some unusual problems, can anyone help. The PC built is a ABIT KT7 Mobo, 700Mhz SocketA T-Bird, 128Mb PC133 ECC Ram, 32Mb DDR Geforce2 GTS Graphics Card, Advansys U/W SCSI Card, 9Gb U/W Seagate Barracuda HDD, 12x DVD Rom, 1gb IDE Hdd, HCF Internal Hardware Modem,and Soundblaster1024. Problems include freezing during games/graphic card demos and at windows startup, mouse not functioning within windows(however start a game and exit and it works?), and DVD movies of any region not playing. I have set the DVD region and still cannot play, also I noticed that windows will not allow me activate DMA on the DVDROM or IDE HDD. Any help? On another note does anyone know of any conflicts in windows 98SE to do with SCSI devices, the reason I ask is that I know windows treats DVD-CD Roms as SCSI and have noticed that it has assigned TargetID=0 and SCSI HostID=0 which is the same settings as the SCSI HDD - could this be causing a conflict?
