Hi there, since my own lappy having crush in graphic chip i'm borrowing my sister.Poorly i didn't check it. Once i bring to my dormitory i just found the message PXE-E61 media test failure, check cable. The time it start to enter the program it's suddenly die, like there's no power supply at all. I did reeboting for several times, and it turned on. Though next to turn it on the same problem happening. Now, i'm trying to do the same and it never ON. When the bar is on progress it's die. It's an old OS, Vista. Help please.
