I was previously surfing the net using Chrome and I had opened many many tabs.. My laptop (Fujitsu Lifebook S Series - S6420) then hung/hannged and I couldn't do anything so I held down the power button to force shutdown the laptop and now I can't restart it.. When I try to, I just hear 3 loud beeps, a long one followed by two short ones.. What do I do? ):

Your beep codes are..
1 short beep System is OK
2 short beeps POST Error - error code shown on screen No beep Power supply or system board problem Continuous beep Power supply, system board, or keyboard problem Repeating short beeps Power supply or system board problem
1 long, 1 short beep System board problem
1 long, 2 short beeps Display adapter problem (MDA, CGA)
1 long, 3 short beeps Display adapter problem (EGA)
3 long beeps 3270 keyboard card .
So looks like a display problem, have you tried any of the recovery/restore options available when you press F8 on boot up
