Yes no more Bip problem One is solved now.
But a new problem apeared.
I start computer, I see the starting Toshiba Logo with the command (f2setup and f12 boot) for less than 1-2 sec. After computer shut-down...
I tried to go in setup or boot none work (f2 and f12)
It's realy strange never had a problem like that before.
I have only one 512mb sodimm I tried it on both slot .. same result each time.
