1. Booting Problems When you press the power button, you give the instruction to the electricity to "wake" up the computer. This instruction causes the computer to start giving its own instructions to internal parts. One of the instructions is called BIOS. The BIOS instruction starts checking "everybody", asking "Are you OK?", "Are you OK?", "What about you?". If a certain part that is important doesn't respond (for example if a certain important object such as the keyboard or mouse is not connected, which means it will not respond when the BIOS asks, "Are you OK?"), then the BIOS may interrupt everything, or it may continue checking. If the BIOS comes to a conclusion that this computer is not worth using, it would display an error and may not let you do anything significant. If the BIOS "thinks" that everything is alright and that the computer can be used, then it gets the hardware parts ready. a. I am receiving an error that says, Invalid system disk, replace and press any key when ready: This error is caused by the presence of a floppy disk in the floppy drive while the computer is booting up. Whenever you turn your computer on, remember to eject all disks from the floppy drive (unless a bootable floppy disk). If you get this error, eject the floppy disk and hit enter. Your computer should continue to boot as normal. b. Receiving a keyboard related error: This error occurs when the keyboard has become unattached from the rear of the computer. Check behind the computer to see if your keyboard is still firmly attached to the computer. Also check to see if something has been pressing on top of the keyboard during booting. Remove all items that are pressing keys and re-plug the keyboard into the computer. Restart your computer. c. I am receiving a no signal error, or there are no visuals on my monitor: A no signal error means that the monitor is .not receiving a signal from the computer. Check to see if the computer is on and running. Then check the connection (cord) between the computer and the monitor. If everything is connected, turned on, and running, then there might be an internal error causing this error to occur. Contact a technician for assistance d. Scan disk appears on a blue screen, stating that Windows was not properly shut down: Scan Disk is a utility that Windows runs automatically when it thinks there might be a problem with your system. This does not mean that there is a problem, but Windows will automatically take this step to ensure that the problem is rectified. Let Scan Disk run and wait, to see if your machine will boot properly after scan disk is complete. If it does not, turn the computer off, and reboot to see if the problem clears up on its own. If rebooting the computer does not solve the problem, contact your technician.
2. Safe Mode Problems If your computer boots to a screen giving you a choice to boot into safe mode, or it automatically boots into safe mode, Windows has run into an error that it cannot bypass to run smoothly. In most cases, you can reboot and the problem will resolve itself automatically. If you continue to get the safe mode screen, or it goes away and comes back frequently, then contact your technician.
3. The system is ON but it Is not responding My system is locked and nothing I press or click is working. What now? Sometimes your computer will stop responding, or freeze, either during operation or after unused for a period of time. If the computer has not been used recently, press a few keys and wait several minutes. If the computer freezes during operation, stop using the keyboard and the mouse for several minutes. If you continue to use the computer when it is frozen, it will prolong your waiting period. If, after waiting for several minutes, you cannot get your computer to respond by using the keyboard or the mouse, turn the computer off by pressing the power button on the front of the machine. Let the computer shutdown (the CPU is no longer making any sounds) and then reboot. If you still get no response from the machine, your mouse and keyboard may have become dislodged from the rear of the machine, check those connections and reboot again. If the computer freezes again after plugging the mouse and keyboard into the back of the computer and rebooting, contact your technician
