I have a Dell Inspiron 560 that does not boot properly. When the computer is turned on, the fans start running at full speed, but the POST screen does appear. Shortly thereafter, a screen comes up with this message:
"Alert! Previous attempts at booting this system have failed at checkpoint . For help in resolving this problem, please note this checkpoint and contact Dell Technical Support."
Below that there are the messages "Keyboard Failure" and "CMOS Checksum error." It prompts to press F1 to continue, F2 to enter setup, but this is where the problem is. The keyboard is completely unresponsive. I can't do anything except press the power button and shut down the machine. I've tried different brands of keyboards, different USB ports (front and back, there are no PS/2 ports), and still nothing. Also, at this point, the system starts making 5 beeps in a row, the fans are still running at full speeds, and the power button is blinking orange.
Any ideas on what to do? I have already tried:
1. Unplugging the system and pressing the power button to drain power for 15 seconds.
2. Resetting the BIOS by using the CLEAR CMOS jumper.
3. Removing the CMOS battery for 15 seconds while the system was unplugged.
Only 1 RAM stick is plugged in, and all add-in cards and hard drives and CD drives are unplugged from the motherboard. Thanks!
