Hello everyone. This is my first post here and I hope that someone can help me. Long story short. Computer spec: cpu: AMD X2 4400 mobo: Abit KN8 SLI mem: 2 x 512MB Corsair value select hd: 2 x Samsung spinpoint 200Gb SataII os: Dual boot with GRUB WinXP Pro SP2 and Kubuntu Dapper I've always had trouble running bittorrent software on this computer. It will always give a BSOD. Either BAD_POOL_HEADER or DRIVER_IRQL_NOT_LESS_OR_EQUAL. The last thing I tried was to update the mobo BIOS (and that seemed to fix it). There are som other issues as well so I decided to do a reinstall of windows and Ubuntu. But. When I try to boot from the windows xp cd the installation program doesn't start. It just hangs with a black screen before the installation program starts. I've tried the cd in another computer and it works fine. The computer will however boot from the kubuntu and ubuntu cd. Before I updated the BIOS my harddrives was displayed as IDE ATA 133 during post. Now they are displayed as SATAII. Please help me.
