My laptop is about 1.5 yr old and the optical drive no longer works. I have not fixed it nor do I even try to use it as it causes the system to crash. Now the computer stops intermittently and I get an error message : 1780 disk 0 failure or 1781 disk 1 failure. I have to go into to setup and try different options to get it to start again. Once it's running its ok, it's only if I leave it for a while and it's in standby with a program running that it reboots to the error message when I start it up again. It is a HDD problem or optical drive problem. HP website says optical drive other people say HDD - help!

1) Remove ALL power to the laptop. Remove the AC adapter (Charger), and Battery.
2) Lay a towel on a table, lay the laptop upside down on it.
3) Look to the side with the optical drive. (DVD drive) Remove the single Philips screw which holds the optical drive in the laptop. Use the tool to push on the notch where the screw was, and push the optical drive out.
High pitch buzz is usually caused by the system fan but can also be caused by the optical drive and the harddrive. check if the system is getting hot. try cleaning the vents of the system. verify that there is no disc inside the optical drive. try booting to safemode and check if the system will still caused the noise. also run a hardware diagnostic to check the fan and harddrive.
Operating system disk - Try to test your Installation CD to other computer. If it doesn't work then you need to replace the disk
Optical Drive (CD/DVD Drive) - If Installation disk works then try to clean your Optical drive lens as it may be having a hard time reading the disk. Your Optical drive is working since you're able to format and able to start the installation. Cleaning the drive lens may do the trick.
Hard Drive - If Installation CD and Optical drive is clean. Then the last thing you need is to replace the Hard Drive. You Hard Drive might need replacement due to some bad sectors and the installation couldn't write anything on the drive that causes to freeze during installation.
The replacement drive is not the same size as the original and the wizard is looking for a drive that size.
There is also a possibility that the error is causes by bad RAM (0A-0543-0000 is a read write error) if you have more than one RAM module try the wizard with one module at a time, see if error is isolated to one or the other module or slot
The Restore CD is dirty/scratched of has a flaw in the original write
The optical drive is defective or dirty
So things you can try:
Clean the media you are trying to restore from.
Clean the optical drive with a drive cleaning CD.
Swap Ram as suggested, replace defective if necessary (OS install is about most RAM intensive process you run on a system)
Try a manual Windows install from a Windows CD not a image restore cd
this problem might slow down if you have too many program installed in your EeePC, i have my own EeePC then I noticed if i put too many programs too dizzy to use it, maybe you don't have put any partition on your hard drive, repartition it. And then put only necessary programs to use. And also use Tuneup Utilities to remove and repair some unnecessary files inside your system. Good luck!
That is not a lot of space for the computer to operate, especially depending on if windows is managing a page file for extra memory, which it does by default. Delete as much data as possible, maybe get more than 10GB of free space. Also, try running the laptop by itself and see how long it will run with just the desktop showing. If it will run for a considerable longer amount of time that way, I would say that the free space is the issue......keep me posted...
