Emachine won’t boot. When power is applied, the keyboard leds and the hard drive led blink. That’s it, no output to monitor, no beeps from cpu. Through troubleshooting I have found I can boot by removing the CMOS battery and power to the hard drive. When I have these removed and I apply power, nothing blinks. Then when I hit the fron panel button, the system starts to boot and I get at the monitor an indication that there was a CMOS checksum error and that I can continue or run setup. If at this point I plug the power into the hard drive and continue, I get an OS not found error. If I then do a alt-cntrl-del the computer will boot and be totally functional. Any ideas. I have already replaced the power supply and CMOS battery. I also let the system sit overnight with no battery installed. Still same symptom and strange bootup procedure that works.
