MSI 975X Platinum motherboard Pheonix award bios V6.00PG Intel 2.39Ghz Core 2 firstname.lastname@example.orgGhz 4x2GB DDR2 800 (Used just 2 GB when installing OS) Installed a brand new Hitachi 7200RPM 1TB SATA HDD prior to install of OS. With 46 updates installed I had 13 update and 40 optional updates to install. I kept getting a failure to install updates error code 800BO0100. Tried the hotfix kb947821 and that didn't help. Tried installing each of the last update individually. Security update KB978601 locked up my system and now I can't even get the system to boot using the disk and repair option. Am going to try to reinstall from scratch, but have my doubts. 1. Win7 doesn't detect video card and install a driver. It come in the updates but causes my screen to go black. 2. Although I've created several backup disks and restore disks, none are being detected by the repair function. 3. Have not flashed the BIOS yet, not sure if I should or not. Update: Got all updates installed and the video driver installed and working. I put 2 x 1GB of DDR2 557Mhz RAM in the motherboard, unplugged every peripheral, and did a clean install. Seems to have worked so far. I'm now going to try installing an optional language pack (Japanese) and then if that installs ok will install Norton 360 premium AV. Could just be that DDR2 800Mhz RAM I had in the motherboard as it is only supposed to take 667Mhz but I was told that the 800 would be ok to use. Perhaps not.
