I have a Gateway 4525 GZ notebook that I've had for about three years now.The computer has always run & worked excellent.Recently I got the blue screen then I ran the XP disc & repaired the problem.About a week later I went to turn on the computer & got operating system not found message now i put the XP disc in again to repair the problem again & windows setup can't find the harddrive now.I took out the old harddrive & installed another one and when I went to install XP on it I got the same message harddrive not found.I've taken apart the laptop & cleaned everything I could & then the dvd drive wasn't powering up. I removed the hard drive again & reinstalled it then the dvd drive worked again. I really don't know what's going here and any help would be greatly appreciated. Thanks for any help in advance.

Re: operating system & harddrive not found
Did you remember to enter the BIOS setup and change the boot drive so the system would look to the (optical) drive in which you have put your XP disk?
In most cases, you must tell the system where to look for boot files and with a new hard drive, there are no files to find.
If you don't have any malware defense installed yet, and can again get it up and running enough to go on line, I would recommend all of the following:
- AVG Free Grisoft Home Page
- Spybot S&D Spybot Home page
- AdAware Lavasoft Home Page
Basic versions are either free or ask for donations.

Computer does not boot upThe problem maybe the RAM, it is faulty or just needsreseating to make proper electrical contact. Reseat the RAM and then boot up your laptop. If it still does not boot up thenremove the RAM module/s and take them to your friendly computer repair shop andget them to test the RAM for you.
Check if the harddrive is detected in BIOS (Basic Input/Output System) setup by pressing F2..or F12 (depends on what key is designed for the BIOS setup).
- If the harddrive is detected in the BIOS (usually shows the harddrive name or values beside "Drive 0"), your operating system is corrupted. You need an operating system disc to install it.
- If the harddrive is not detected in the BIOS ( no value beside "Drive 0"), either the harddrive cable is loose, the harddrive is not inserted properly or is defective. Check the harddrive compartment at the bottom of the laptop and use screw driver to reveal it. Try to reinsert it or use a good known hard drive.
Restart the computer while tapping the deleate key this should bring you to bios go to advanced and check if the harddrive is listed with it highlighted press enter to enter the sub menu make shure its not disabled if it is enable it hit escape key to exit sub menu go to Boot on main menu set hard drive as 1st boot device set cd/dvd drive as 2nd boot device press f10 to save changes and exit. Try restarting
if you get msg opperating system not found use the system restore disk
Hope This Helps good luck
Please leave feedback
I would say either a bad harddrive or bad boot sector. If you are looking for a DIY solution, youll want to test the harddrive by running disk wizard or something similar or pulling the harddrive and putting it in a harddrive enclosure (available from NewEgg.com). The enclosure will hookup to another computer through usb or firewire and will allow you to backup your files if the harddrive is still good. If the harddrive isnt good, youll get errors while copying the files or it wont allow you to access the harddrive at all.
Else, take it to a computer repairman to have them pull the harddrive and run tests on it.
There is a part number which you can use to order, so it can be replaced.
Part #: 103336
This article describes how to replace the device. Replacing the optical drive is on page 3.
