And thank you for the link to the BIOS upgrade page... There were 3 files listed for BIOS updates. I downloaded them all 1. BIOS update 2. Processor microcode update 3. Business Desktop BIOS utilities I opened the BIOS update (1) in Archive Manager, it was called sp4423.exe. I tried to extract a file from a folder within the exe file. It failed with an error. Tried again, extracting everything to a sub-directory. It worked. Went to the BIOS CD sub-directory and burnt a CD-R with the contents of 7D1_0161.iso I did this on HP Compaq dc 7600 PC (hostname : aristotle). * Booted PC from the BIOS update CD-R * Got into the BIOS and flashed the BIOS Updated. Rebooted. Changed GRUB_CMDLINE_LINUX to "". Rebooted. Back into nice graphics. All I need to do now is use the computer for a while and see if the graphics horizontal line problems have been fixed.
