The freezing issue could stem from these problems:

corrpupt/bad software on HardDrive for operating system

bad drivers for the unit

motherboard overheating

lets start off with a few things. first tap f8 select safe mode. see if you get the freezing up issue then.
if you dont, then its a driver related issue:

for driver related issues, go to and download any available updates to your software (bluetooth,wireless,video card, and so on) including the bios flash update. you will more than likely have to get these updates by booting into f8 selecting safemode with networking to get access to the internet.

If the machine freezes up still , then its either a corrupt O.S./bad hard drive or overheating issue with motherboard.

to determine the issue reboot the machine after it freezes, go f8 for safe mode boot w/networking and do this:

go to and download all the updates for the driver software and bios (bios is very important) there have been some updates to these areas for issue related to motherboard problems. after you install all the updates select to not Restart computer yet (which it will ask after video driver updates and so on) now go to my computer, right click it, select properties and in the tools tab select the disk check option. from there check both boxes and then restart machine.

what this will do is check the disk for errors and bad clusters, and load the correct new/updated drivers, when its done it will restart and by then have moved bad areas to new places. if it freezes up during this process the drive may have hit a snag and you need to replace the hard drive.

if you continue to get this problem after all this, i suggest seeking professional assistance for motherboard overheating issues. i have fixed those problems by applying new thermal paste to the heatsink fan assembly and adding it to the GPU chip also. but in some cases i had to reball/reflow the GPU chip, which runs 80-140 depending on where you go. ebay has a few good vendors that do this.

Good Luck! I know its alot, but that should eliminate the majority of issues

Installed new mother board to hp dv4000 laptop all went well but after 10 min ish the computer freezes and has to be forced to shut down like it is getting hot and will not reboot with the display working...

is that an original mobo from the manufacturer? if not or yes i think one of the chips might be getting burnt due to a short circuit...claim a warranty repair or replacement... it might be one of the voltage controller chips or capacitors that was burnt... might b a dust issue too

The usb ports won't work on my hp pavilion dv4000. i would appreciate any feed back that i could get. The whole computer freezes up when i plug a flash drive or any other usb device into it.

TWO THINGS.. 1) open device manager and look to see if its listed there. If not, go to step 2. If its listed, at top click VIEW and choose "show hidden devices". Uninstall any devices that are currently listed and installed. Close and restart.
2) Go to to download the current Updates for your system. That should solve your problem. By the way it would be a good idea to update your system on any account. Always a good idea!! :) GREAT LUCK!! Please rate me , k? Thank You- Lucky4lynn2

HP Pavilion dv4000 motherboard freezing

There is a chip under the pc card cage that gets cold solder points and ends up breaking loose. The motherboard will need to go on a special rig to be resoldered. It would be faster to just purchase another motherboard on Ebay and install it. The motherboard part number is located in the Ram memory compartment. There are repair firms out there that are capable of repairing these but I am unsure of what the cost would be. I will include a service manual link below to guide you in the disassembly of the laptop.

Freezes when jostled

sounds like a connection to the hard drive may be loose.

No matter what it is it will have to be taken apart to fix.
