Has someone worked on the laptop and opened the case? If so, it may be a simple as the keyboard is not plugged into the motherboard.(We should be so lucky). If the external and the internal keyboard don’t work, the translator chip needs to be replaced.

Are you using a “real” copy of Windows or, a “bootlegged” copy. Reload Windows. If the problem persists, do a clean reload. # Make a DOS boot disk with format and fdisk on it. (1) Boot from the floppy and run fdisk /u /r. (2) Run format c:/ /s (3) Boot from the HDD and load Windows.

Is this alert in the boot up process? (Replace the BIOS battery, the silver button battery on the motherboard, usually a 2032 3V battery) Is the alert in Windows? Clear the battery settings in the Windows setup screen.

When you replaced the PSU, did you replace it with a more powerful one.(i.e. replace a 250W PSU with a 450W PSU.) When a Windows machine boots, it runs the BIOS (Basic Input, Output System) first to check all your hardware, including memory. When it finishes then it will load the Operating System(Windows). # Do you get any error messages when it fails? Does it fail after it starts? Does your BIOS process properly?(Beeps and light flashing on start up to indicate the BIOS is checking your hardware) # It may be a BIOS setting. You can get to your BIOS as described by your motherboard designer. Are you an “overclocker”? Reset your BIOS to all default settings and then try it again. If it still will not start, after loading the default settings, do the next step. # Disconnect all peripherals, (printers, scanners, etc). Then disconnect floppy drives, CD/DVD drives and other internal devices.(including the Hard Drive). Note: your computer will not load the operating system. (1) If you do all this and it still...

I would replace the PSU with a newer more powerful PSU.

Something is telling your power supply to "reboot". The easiest way to determine what is causing this is to unplug things one at a time. Turn your PC off and unplug it. Then remove the power connections to everything except the motherboard. It should run through the POST examining everything on the motherboard and the video. You should see your BIOS splash screen. If it continues to reboot, it is possible there is an erroneous setting in your BIOS. If not, plug things in one at a time and reboot the PC. When it starts again, you have your "guilty" device.

You can go to HP.com, look up your particular printer and find the most suspect area for a paper jam. It could be several places. As the paper traverses the paper path, it is timed. if the leading edge doesn’t get someplace on time, it will fault out. It could be your paper pickup rollers, or several other places depending on your make and model. LaserJet 4’s are notorious for output jams, for instance. Also, there could be a tiny piece of paper torn off and jammed into a corner somewhere that catches the next feed. So, if Mr. Knight’s fix doesn’t work, please post what type of printer it is (LaserJet 4, Colorjet 4030). What error code you receive on the display. The age of the printer. If it is an old printer, it is probably the paper pick up rollers. YouTube is also a good source of info for this type of problem.

If you PC will work with an old video card (GPU), it is not the PC’s problem. Your new GPU may be over powered for what you are running. Check the specifications to make sure you have enough RAM and that your CPU is powerful enough to run the new board. If all the specs are good I would suspect another item that a lot of people don’t think of, the PSU. If your power supply is not big enough, it won’t be able to power your new board. You can test it by removing all other boards from your PC except the GPU. If you don’t have other boards in there, like me, just replace the PSU with a larger one. Look at the label on your power supply. It will tell how many watts, it will output. i.e. 200W. Put in a 300W PSU, reconnect everything and try it again.

Have you descaled the machine lately? If you have hard water like I do, you would be surprised at the amount of gunk built up in there. Can you get a consistent water delivery? In other words if you press medium, do you get the same amount all the time? Have you tried the Keurig.com website? They have some good info. Also, a lot of good info on You Tube about the Keurig.

Never clean rubber parts in your printer with alcohol. It removes the natural oils and dries out the rubber. Use only soap and warm water.
