"destroys" keyboards and motherboards

I have been able to bring my computer up, but once I get up and on line, a blue screen with a message comes up
and my keyboards is not longer usable. I took it to a local
computer repair place and they have not been able to
identify the problem and fix it. As I watched them work on
it, it burned up 3 motherboards and 3 keyboards. He is
not sure what the problem is. He thinks it may be the
processor, the power supply, the motherboard (which he
burned up 3 of while I was there). any ideas. I haven't had my computer for 3 weeks and I need it now.

No boot


Turn on a working computer with its keyboard plugged in and test if the keyboard is working properly.

If it is, shut down that computer, unplug the keyboard and plug it into the system that is suffering from the missing "NTOSKRNL.EXE" file.

Turn on the system to see if the replaced keyboard resolves the problem.
Press the "F8" key right after the system initializes the boot sequence and before the Windows logo shows up to bring up a menu of boot options.

Choose the "Last Known Good Configuration" option with the arrow keys and press the "Enter" key.
Insert your Microsoft Windows installation disc.

Restart the computer and press the "R" key on your keyboard once you reach the "Microsoft Setup" menu.


Choose the operating system that you wish to repair, type in your admin password when prompted and press the "Enter" key.
Type "bootcfg /rebuild" and press the "Enter" key to rebuild the Windows "boot.ini" file, which may also resolve the issue.

Type "chkdsk /r" and press the "Enter" key to scan the entire hard disk for errors.
Type "exit" and press the "Enter" key to exit the "Recovery Console."

Restart your computer and see if Windows boots properly.

Ecs 945gct m3 v h motherboard ver 3.1


Your motherboard keyboard controller is not initializing completely. The three LEDs shows the keyboard is powered and initializes, but the motherboard keyboard controller looks to be bad. I assume the keyboards work on other computers. Make sure there are no jumpers on the motherboard for the keyboard. You said the video screen is stuck on CMOS BIOS logo and is trying to continue with a missing keyboard or keyboard error. So since it got to the BIOS screen, pretty much everything else came up.

I have dell Optiplex 380 series, before during I am using, it suddently blue screen, and after that i power off the computer, after that i have power up unfortunately it wont start it load the message...


Sounds like the motherboard died. Open the case and look at the capacitors towards the raer of the case. If any of them are buldging, or are leaking a brown "goo" the MoBo is toast.
Fairly common problem in early Optiplex units.

Hp pavilion dv7-4165dx black screen


A blacked-out screen doesn't necessarily indicate a broken monitor.
If the computer has run out of charge or is in hibernation or sleep mode,


if the screen is too dark, or if the display cable has come disconnected from the motherboard, the screen may appear black or fail to turn on.


To fix a blacked-out laptop screen, troubleshoot the screen settings, check the LCD connector and see if the computer is awake and receiving power.


Touch the touchpad or move the external mouse to see if the computer is asleep or hibernating. If the computer fails to respond, press "Enter" on the keyboard.


Press the power button if the screen remains black.

Confirm that the power indicator light, found at the front of the computer or above the keyboard, is glowing solid green or blue.


Confirm that the power adapter is plugged into the computer and into a wall outlet. Confirm that battery indicator light is glowing solid green or blue.


Hold down the "Fn" key. Press the up-arrow to see if the screen brightness increases.
Some computers also use the "F6" or "F7" keys to increase screen brightness.


Hold down the power button for 10 seconds to turn off the laptop.
Remove the AC adapter from the computer, close the screen, and then turn the PC over.


Slide the battery latch to eject the battery. Pull the battery out of its compartment.


Turn the computer back over, open the lid, and insert the edge of a flathead screwdriver or other flat, solid object beneath the bezel above the keyboard.


Wedge the edge of the keyboard bezel off of the top cover.
Work your way along the edge of the keyboard bezel to loosen it.
Pull the bezel off the laptop.


Trace the cable coming from the laptop screen to the connector found beneath the bezel. Reconnect the display cable to the motherboard if the cable has come loose from the connector.

Line up the tabs on the bezel with the slots along the top of the keyboard. Insert the right edge of the bezel into the gap above the keyboard, and then push the bezel back in place.


Turn the computer back on. If the laptop screen is still blacked out, connect an external monitor to the video port on the side of the PC to confirm that the video card isn't defective.

If the external monitor works, the LCD screen could be broken.

If the monitor doesn't work, the motherboard or video card might need to be replaced.


Hope this helps

Hp slimline computer cannot bring up keyboard and monitor


Buggy Motherboard... could be the BIOS could use an upgrade, Bad Battery on MB, or MB could just be bad. Data on you drive is good and recoverable. New PC ? Buy.com a Referb Box is a good choice if you are on a budget. A Turion Processor is not worth the expense to fix in my opinion. If you can do it youself,for fun, replace Motherboard, HD and CPU and re-use the rest. Buying a new one, even a real cheep one is a less frustrating solution.

Dimension c521 computer gives a post error, floppy drive 0 error and keyboard error


Hi,
The compute post tests the computer, insuring that it meets the necessary system requirements and that all hardware working properly before starting the remainder of the boot process.
1 Short Beep, Normal POST, computer is okay. No problem. 2 Short Beep, POST error....floppy drive 0 error and keyboard error........This can happen because there is something wrong with your floppy drive, something is causing your computer not to detect it or that you simply don't have one.
Check your floppy cables and connections first to ensure that they are connected properly, if they are then you may have a burned out controller on your motherboard, a bad floppy cable or drive, or your motherboard may be faulty. If you don't have one you can disable the message in your computers BIOS. To get to the BIOS screen, during boot up at the bottom of the screen it will say something like "press F2 for setup" or something along those lines. That will take you to the BIOS screen. In the settings there should be options like first boot device, second boot device, and so on... change the one that say 3.5 floppy to something else such as your CD rom.That will get rid of that message.
Keyboard error or no keyboard present shows up when your computer can't find your keyboard or there is something wrong with it. Replace with new keyboard. Thank you
