i used to have a 1gb ddr2 533 mhz.....i recently added another 1gb 667mhz of the same brand......
i notice that windows takes 5min to boot(used to hardly take 1min).....then every game i run(including oldies like diablo2)....the game freezes for a few seconds n this happens every 2 mins.
all this happened the minute i added the 1gb 667....
i ran mem test n it dint show anything wrong,bios shows 2gb of ram....y is this happening
