socket 370 feasibility issues...

I'm new here so bear with me...I have m754lmr pc chips mobo with built-in video going out and showing "streaks". I'm not currently using it but it works, I'm running Windows 2000 on it with 256mb of memory (16mb shared), a 9.5gb hd and the ol' Celeron 633mhz cpu-66mhz fsb. The question is...can I install a Pentium III (800mhz-1ghz) cpu? and if so, would the bios have to be "flashed" in order for the mobo to support 100-133mhz fsb? I figure I'll have to install a video card for it as well (along with memory upgrade and hardrive). I ultimately looking to breathe a little life into the ol' girl...Hit me back...
