Lcd screen shows severe blurring when moved,keyboard is locked when used with PS2 port
my computer is compaq presario P6240 IN (2003) it is P4 and the mother board is Xenon.The screen gets blurred when any running programme is scrolled updown or sideways. keyboard and mouse do not work through PS2.i have connected them through USB but still some times the curser gets locked up at start up. the screen resolutuion changes sometimes at start up.
Re: lcd screen shows severe blurring when moved,keyboard...
Could be a number of things...motherboard,hard drive going bad or as simple as a virus/spyware problem. I would formatt & do a clean install of windows to illiminate any virus problems. Then if it still has this problem, look to the motherboard & hard drive.

Shut down the computer and disconnect the USB keyboard. Connect a PS/2 keyboard to the PS/2 connector port on the rear of the computer. Enter bios restart your computer you will see a certain to press to enter set up usually the Delete or the F2 key this will vary depending on you computer and bios. Wait for the main BIOS setup screen to appear. Press the right or left arrow keys to move the cursor to the "Advanced" or "Advanced Settings" menu option. Press the "Enter" key. Move the cursor to the "Integrated Peripherals" or "Peripheral Configuration" menu option. Press the "Enter" key. Press the down-arrow key to navigate to the "USB Controllers" option. Press the "+" or "-" key to change the menu option to "Enabled." Move the cursor to the "USB Legacy Support" or "USB Legacy Function" field.

As soon as you see the initial boot screen, tap the "Delete" key several times and wait for the BIOS setup screen to appear. If you are able to access the BIOS setup screen with the USB keyboard, USB support is active in the BIOS.
Enable PS2 & USB in BIOS You can enable PS2 and USB settings in BIOS by entering the BIOS setup screen when the computer boots. You will need to changes to the appropriate settings in this screen. The exact procedures vary by system, but there are a few common methods that may work if the motherboard manual is not available for guidance. The general procedure is the same for any modern computer system, but the menu arrangement and keystrokes to enter the setup program can vary greatly from one machine to the next. Power on or restart the computer and watch the initial boot screen to find the keystroke required to enter BIOS setup. This is often shown at the bottom of the screen. Typical keystrokes include pressing the "F1," "F2," "F9," "F10" or "Del" key. Press this key when the prompt appears on the screen. You can find the proper key in the computer's motherboard manual or on the website of the motherboard or computer manufacturer. Enter the BIOS setup screen and look for the "Advanced" or "Onboard Device Configuration" menu. Use the arrows to select your choice and press "Enter." Change the settings for the PS2 port by moving the menu choice to the "PS2" setting. Press "Enter" to bring up a smaller menu with the options to enable or disable the PS2 ports. Select "Enabled." You can also use the arrow keys or the plus key to change the current selection from "Disabled" to "Enabled" in order to enable the PS2 port. Change the settings for the USB port by moving the menu choice to the "USB" setting. Press "Enter" to bring up a smaller menu with options to enable or disable the USB ports. Select "Enabled." Alternatively, use the arrow keys or the plus key to change the current selection from "Disabled" to "Enabled" in order to enable the USB port. Save the settings and exit by pressing "F10" or using the "Esc" key to back out of the current menu. Choose to save and exit from the main menu if needed. Follow any additional instructions on the screen to save or navigate the menus. Hope this helps.
Check that it is indeed plugged into the purple PS2 port on your computer, if the keyboard is USB then try alternating ports. Some-times just by plugging it into another USB port it can work.
Also it maybe that the keyboard has died, try a friends keyboard on your computer to test it. Try do as much as possible before purchasing replacement parts.
Either your Hard drive (hd) crashed or your hd cable or port is faulty. if your software is corrupt boot with a boot disk (assume you are using XP or Vista), press R on the blue options screen. you will be given a black dos prompt screen. Type in fixboot and type Y for an answer.
1)chect to make sure a keyboard is in the PS2 port or usb, whichever you are used to.
2)if your computer gets past this screen but does not boot, you will need to reinstall your OS, but this will delete all your data.
if your keyboard problem persists, get a different keyboard with the connector you usually use.
I have seen this before, and the best answer I can offer you is some Motherboards are better than others when working with usb devices while no OS is in place. I actually tried using usb / to / ps/2 adapters and it still would not recognize the usb keyboard in a couple of instances. I had to get a ps2 keyboard for the installation of windows. After windows was installed I hooked up the usb keyboard and it worked fine. (just speaking from my own personal experience here)
Sorry I do not have a more technical answer for you but I'm almost 99.9 % sure this should work, providing there is no problem with the ps2 keyboard port on the Motherboard. I have never failed to install windows unless there was another hardware based issue of some kind, but never a problem with a known good ps2 keyboard.
Just double check everything is seated properly and try to get into the bios setup, if you cannot use the usb keyboard for this, you can try the usb / ps2 adapter, but if that doesn't work either then use a regular ps2 keyboard. That should work fine, then after setup is complete, windows is installed, then your usb keyboard should work fine.
start (button) select control panel / system / hardware / device manager / mice & pointing device / double click, select wheel mouse (or whatever mouse you have) right mouse click, properties, select use this device (enable) - But I'm surprised you are having trouble with it.. Have you changed anything recently? Have you always used a ps2 mouse? Try connecting the mouse & re-booting the pc.. Also make sure it's plugged into the correct port, not the ps2 keyboard port.. Especially checkif you are using a usb keyboard.. Rgds
