Hi Im having a problem where my motherboard will take a PII 350 but when I put a PIII450 or PIII550 in, the dam thing locks up when I get into windows and start up a prosses draning program ie media player. ??

I have a partner motherboard ApolloPro133 with latest bios the manual says it can take up to PIII 600 and latter versions... but i know these CPU's work in other PC's so what could be the issues ??

I cant find anywhere on the main board or in the bios to change cpu voltage but both the 350 and 450 say they are 2V so I dont think this is the issue ?? please help I dont want to be running a 350 when I have a 550 sitting here..
