I used the Ultimate Boot CD on my computer, and opted to disable certain BIOS items from starting. When I restarted the computer, I could not get past the startup screen or get the computer to read the CD player to undo these settings, so I went into the bios settings in the start up menu and disabled some more items from loading at startup. Now the computer won't come on. I took the battery and jumper out, but no luck. What can I do? It's a Windows 2000, running XP.
It sounds like you have a real dilemma here, especially since you have already taken the battery out with no resolution to the problem. Try the following suggestions and see if you can get the computer to run again. I am also going to suggest taking the battery back out, just in case.
Boot UP Using Safe Mode
The first step that you need to take is to see if you can boot the computer up using "Safe Mode." Follow these directions:
- 1) Turn the computer's power button on.
- 2) Immediately begin to press the F2, F8, F10, or F12 (depending on your model/brand of computer) key on the keyboard to allow the computer to start up in "Safe Mode."
Reset the BIOS to Original Settings
Removing the CMOS battery/resetting the CMOS jumper cable resets the BIOS back to its original settings. It's important to wait long enough when you take the CMOS battery out before replacing it. So, let's try this strategy once more.
Disconnect the computer from its power source and discharge the electricity before you begin. Remove the CMOS battery from inside the back of the computer. Wait several minutes before replacing the battery. The same thing holds true when resetting the CMOS jumper cables. You need to wait several minutes before you flip the switch back.
Replace the CMOS Battery
If your CMOS battery is more than a few years old, you can consider replacing it with a brand new one. It is possible that installing a fresh battery might resolve the problem of your computer not turning on for you.
While these issues aren't likely since you sound like you know what you are doing, it still won't hurt to try them. Double check that the computer's memory is properly seated and that the power cords are properly inserted. If your BIOS is beeping, count the number of beeps and look up what that number indicates for your specific brand/model of computer.
