My computer started shutting down almost immediately after startup recently. I did a bit of research from forums like this one. I decided to do a bit of troubleshooting.First, I decided to see if I had some bad memory. I removed bank 2 and that stopped the shut-downs. Guess that was the end. WRONG.I took out my CD burner and found that it had no jumper pin. So, I tried the different settings. It started shutting down right after startup, except when there was no jumper at all. Does that mean that something is wrong with my burner??? Shouldnt there be a jumper on the master setting???Any other thoughts???
