I'm helping a friend with his Emachines ET1161 and got it upgraded to Windows 10. At some point while having some difficulty with the upgrade, I thought it might help to update/re-flash (don't think the version actually changed) BIOS. I downloaded and flashed BIOS from Windows--later I re-flashed from DOS (after the problems described below started).
Since the BIOS upgrade/re-flash, the machine no longer reboots. Windows acts like it will reboot and the screen goes blank, but fans keep spinning, power LED stays lit, etc. If I choose shutdown instead, the system does power off.
The system will no longer boot unless CMOS is cleared/reset, even if I only hit F1 to continue, when prompted (not making any changes to BIOS settings). I installed a new Energizer CMOS battery. This made no difference, so for now I pulled the CMOS battery to simplify booting. If I choose restart in Windows, eventually I have to hold the power button, flip the switch on the power supply or unplug. To boot the computer after shutting down (or fake reboot), with the CMOS battery removed, I unplug the computer from power and wait 30 seconds or so. I then plug the computer back in and hit the power button. After a bit, I see the message, "CMOS checksum error - Defaults loaded." It tells me to press F1 to continue. If I do so, Windows boots normally.
If I try to boot without first clearing CMOS, the system powers on, but I see no POST screens and no OS screens. The display/monitor indicates no signal.
Before I removed the CMOS battery altogether, I had jumpered the 3-pin CLR_CMOS pins in the clear/defaults position for 20 or so seconds, then put the jumper back in its original position. This is how I discovered the system would actually boot. I also replaced the jumper in case the original got damaged somehow. I confirmed the jumper is in the non-clear position.
Any suggestions?
Thank you!
