Unlikely. They both would have to be running a motherboard that you can take off the cpu. And the cpu socket would have to be exactly the same on both motherboards.

If there is one it will be on your manufacturers site.

Get onlineand got to www.google.com In the google search box type: "HPSupport" or "Compaq Support" (without the quotes and put your manufacturer name before Support). Look for downloads and drivers. Enter your model number and operatingsystem when requested. Look for Manuals and documents.

bluescreen can be caused by a number of things

a bad driver loose or faulty lead or not having enough ram

click start control panel administration tools computer management device manager scroll through all of your devices

if you see a yellow question or exclamation mark ? ! or a red X you will need to update the drivers for this device right click select update driver/reinstall driver

if you can see your usb device but its not working scroll to Ports(Com&Ltd) right click to update driver

if you computer came with a motherboard disk the drivers could be on it

or you might have to download one

you might not have enough RAM random access memory not having enough will cause your computer to run over its maximum limits and can cause the blue screen of death and hang and cause memory dumps

make sure your ram modules have a dust free secure seating and the CPU central processing unit has thermal paste
if you dont want to install more ram uninstall some unnecessary programs

a bad or faulty motherboard lead or its connection if its a flat 40 pin ide it will be the first to fail
make sure all leads have a dust free secure connections

hope it helps

There might be a setting in the Touchpad software that allows you to turn it off. Click Start Control Panel and look for Mouse or Touchpad.

There might be a button located at the very top of the touchpad in the middle that toggles it on and off.

The machine will not start again until a new bios chip is installed or the
board is replaced.
On a desktop a procedure called "hot flashing" can be done but not on a
laptop unless you have the proper equipment and know-how.
Hot flashing is where you get and identical bios chip and replace the one on
the board. After the system is started you pull the chip will the system is on and
replace it with the bad flashed chip. Then you do a regular bios flash upgrade. The key is you
need an identical bios chip to start the process. On a laptop you need either and a identical
chip or the ability to write to the bad chip. Oh and I forgot to mention you need the equipment
to take the board out of the laptop case and get it running
One of two things needs to be done:

1) Replace the motherboard

2) Find someone who knows what they are doing and remove the chip and
reprogram it. You should be able to find one of these guys under Google.

right click on the touchpad symbol in your taskbar and modify the pad settings so right click is only enabled with right mouse button click.

Hi! Please remove the battery first and then let it sit for another 48 hrs. This may reset the system and get it back to normal working condition again. Please write back on the progress. Hope this helps and thank you for using FixYa!
