Hi I started having problems with a BSOD on startup a few weeks ago (had Windows XP Pro SP3 on hard drive and Linux Centos on USB HDD). I removed linux from the mix and reformatted my windows hdd. Still I have the BSOD on startup - most annoying. Have done a disk check, cleaned out the inside of the machine, done a defrag and run Memtest - all good but I am STILL getting the BSOD. I would appreciate some help. Thanks! In event viewer this shows: The computer has rebooted from a bugcheck. The bugcheck was: 0x10000050 (0xa6b98000, 0x00000000, 0x8052b8ec, 0x00000000).
