I upgraded the RAM and reseated the processor on an Asus IPILP-LC Lancaster 8 board in a Compaq SR5233wm desktop. When I put it back together, it now has no video signal. It wont work with the original RAM either, so its not that. Somewhere I read something about resetting the battery or bios, and something else about the CMOS. How can I load a new bios or sata driver, etc without an OS, or being able to see anything on the monitor? Its driving me craaazy! Someone please help me.
