1.	Solve : E-machine T6420 wont boot up..?
Answer» The problem is this. When I turn on the PC all I get on the display is "No signal detected" (monitor is good). The PC acts like its in sleep mode. For awhile I had to turn on/off to get it to boot. I visually CHECKED the mobo and found nothing wrong. I now have to UNPLUG the PC to turn it off. (maybe a bad switch?) The following things do run when I turn on PC. The power SUPPLY fan comes on The CPU fan comes on The keyboard lights come on The HDD light comes on and stay on The DVD drive light comes on Things i already tried before booting up PC Disconnected HDD, and then the DVD drive. I pulled the CMOS battery and placed it back Disconnect the mouse Im really frustated with E-machine reps .. No help what so ever.. Told me to take it to repair shop where I bought the thing. Any suggestions would be greatly appreciated. Most likely it's a motherboard problem. I've run many calls and have ended up replacing BOTH the motherboard and power supply to make it right.
