I started up my IBM today and nothing came up. The Power light showed but the busy light didn't do anything, it didn't even show the IBM BOIS screen. I tried multiply times to restart it and sometimes it got to the windows loading screen after going through the IBM screen but then it would freeze. I tried taking off all its hardware (harddrive, RAM, Wireless, battery) as said on the IBM website, but it still didn't start. My computer has 2 ram ports, so i changed them, and when it was starting it beeped, paused, Beeped 3 times, pause 3 more times, pause and one last time. So is there something wrong with my memory? because it starts up some times but it freezes during it? Please help!
