Is the techo going to re-solder the video chip to the motherboard and get the laptop going again, or is he recommending a replacement motherboard?
The overheating problem could be causes by a faulty fan (stop spinning or spins slow) and or dust clogging the fan and heatsink assembly.
The cost of repairing or replacing the motherboard may not be worth it and may be better to put the money towards a new laptop.
You can used the old hard disk by putting it into an USB hard drive adapter case and use it as an external USB hard drive.

Please run system restore from your control panel to an earlier date.

Try contacting hp through their live chat and aqsk them how to reinstall the mousepad driver. if they cant help try restoring your computer to a date before the problem started or reset the operating system.

Cracked screens have to be replaced, they cannot be fixed.
