Hi guys, I have the following problem,Iwanted to add more memory to my pc it had 1 stick of 256 sdram,I have bought 2 sticks of 256 pc2100ddr,the problem is when i put the new ram in the pc boots up then i get a funny muzzy pc screen. I took the ddr sticks out and put back in the sdram nad it works . So could any one advise me on what i have done wrong?. Do i need to do anything in the bios?. Iwent to crucials web site and got a list of compatible ram and it lists the ram i bought. My motherboard is made by elite group model number P4VMM2 (VER 5). In the manual it says the board has 2 banks of ddr and 2 banks of sdram. My pc is running xp sp2, the processor is a celeron 2ghz.
