C'mon! Don't be so rude to me.
I’m tortured by the 2nd-hand computer for 3 days! I’ve tried many different ways that I know to let it work. But I was failing all the time. The system halts everytime. Judged by all that I tried, there should be sth wrong with the mainboard. I detached all unneccessary parts such as modem, network adapter, 1394 card… It doen’t work. I don’t know what to do now. Would you please show your mercy,GOD?
