I have some weird problem. When i try to boot - BIOS began to beep. From manual i found that 2 beeps mean problem with the RAM. I replaced it with new RAM but the problem still exist. So i try to disconnect other parts of laptop. And find that with disconnected touchpad laptop starts fine and BIOS doesn't beep anymore. So i try to plug-in touchpad during Windows booting - and it WORK!!! Yes - in Windows it work pretty fine.
So I have no idea what problem. May be someone have any suggestion?
