If this were a backlight problem, you probably wouldn't be able to see the Toshiba Splash Screen. Do you see a little dash at the top of the screen? It sounds like your hard drive has lost its MBR (master boot record) or completely failed. The MBR tells the system where to find the operating system on the drive. Try finding a Windows OS install or upgrade disc or your Recovery disc. (For a Windows CD, you'll want to match your current OS.) Alternatively, find a LiveCD of a drive partitioning program (with a repair MBR feature). I've used the True Image and Paragon Partition Manager.
Try to boot from the optical drive. (You may need to access the BIOS to change the boot disc; press F2 after powering up the computer. If you get to the blank screen, then shut down and retry. It takes me several attempts to get into the BIOS.) If you can get the boot CD to work, try to repair the computer. Let me know if you need the details. It will depend on if you are using Windows media or a Partition repair Live CD. You can also try to restore from your backup. (I hope you back up regularly.)
The Diagnostic Utility was deleted either by the person who repaired your computer most likely. This partition is used for recovery purposes and is installed by the factory. If you have the proper recovery disc that came from the factory you will need to do a complete re-install to factory default. If you do not have the original disc you will need to get one from Dell to bring your machine back to factory load. This disc has everything that was installed including the partition as well as the drivers and other software that came with your computer when you purchased it.
Now assuming that the technician had restored the computer back to factory specs you should not be missing the Diagnostic Partition you may want to return this to the person you paid to this fix and get them to restore it back to factory specs. Now if you did not have the recovery CD at the time when he began the work he was forced to do a format on the drive and use a purchased disc from Microsoft which he had to also search and install drivers himself. This is a problem because it would then not be his fault. He did what he had to do bypassing the factory stuff when you purchased this laptop now it is at the hands of independent software and not the original with no other partitions others than C: Which in many cases especially laptops can cause issues with devices not being installed properly outside of the scope of the original recovery CD.
With all that said make sure that you are booting from the DVD or CD-ROM drive as the first boot. You will have to go to the BIOS to check this out. I advise you to use the original software that came with your computer. Insert disc into the drive and re-boot and follow the onscreen instructions that is all you can do, if this does not work you will have to bring your computer to a repair shop and go from there.

When deleting the operating system you have to have a restore disc or the master disc for an Operating System to be re-installed again. You will then have to insert the Operating System disc in the drive and then restart select boot from CD or DVD whichever you have on your lap top then you will have to format the drive with this disc it all should just do it for you select complete install. This will wipe files currently on the hard drive and enable you to restore your machine back to its original condition as you purchased it.
You computer should be by default to boot from CD ROM first boot. If not get to the BIOS press F2 when the system first boots it will take you to the BIOS then set in the BOOT order as first boot being CD or DVD first boot and hard disc second boot. Then restart and have the Operating System Disc in. If you do not have an operating system disc that came with your computer you can get one from Dell just order it and use this disc. Do not try to install just the basic Windows because Dell has all of their drivers installed on their restore discs and you will play heck trying to get the drivers. Unless you have a legal copy of Win 7 go ahead and go for it then. Making sure to be online when installing Win 7 so that it can seek driver files during the installation.
I hope this assisted you. Thanks for using FixYa for all your questions. John
There are a couple possible solutions to your problem. If the computer will still turn on and load windows, and I assume you are using Windows XP, you can try doing a system restore. To do this, go to Start, Programs, Accessories, System Tools, and select System Restore. If system restore is enabled, you should be able to choose a date in the past when the laptop was working properly and restore the computer to that date. If you want to completely reload windows, you will need a Windows XP installation disc. Load the disc in the CD or DVD player and reboot the computer. You should see a screen asking you to press any key to boot from CD, go ahead and press Enter. You will now enter setup where you can reformat the hard drive and reload windows XP. Follow the on-screen instructions to delete any old partitions, and then create a new partition and format it using NTFS. The windows XP installation will continue after the hard drive is formatted. If, when you reboot the computer with the installation disc in the drive, you are not prompted to boot from CD, you may need to reboot and press F2 or F12 to change the boot selection to the CD or DVD drive so it will load the CD first before it tries to load your original Windows installation.
Haven't used win98 for a while so bear with me and this uses DOS COMMANDS too. If useing restore cd/floppy you have to use a utility from compaq that creates two partitions on hard-drive. They may have a restore floppy if you need it too. One for "recovery files" and one for "OS Boot" AHH, the memories, I still have my 95/98/ME Laptops up and running for older stuff. HP n CQ too. Restore CD should do it all though. If no restore CD - have Win98 CD? if Harddrive partitioned and formated - Just do 1 1. boot from Win98 CD. Partition n Format 2. Choose boot to DOS (puts u in virtual drive A) AT PROMPT 3. Type drive letter of CD ( C: D: or E: ) 4. Type CD Win98 5. Type Fdisk ( to partion drive) reboot n do 1 + 2 6. Type format C: ( I do this to ckeck drive for errors) OR JUST Boot from CD and follow install instructions. 1 to 6 for if you have problem with Win98 CD setting up Harddrive.
1st Option: Go to BIOS level and select the CD/DVD device is the first device for boot option and then insert the recovery CD/DVD to format or install OS.
2nd Option: If recovery CD/DVD got curropted and you are having the other OS CD/DVD, then try to load and format or install the OS. Also try to download the recovery image from vendor website.

With the OS X Installer CD in the drive, try booting your mac and holding down the option key immediately after you hear the start up chime. This will (hopefully) load a firmware boot loader that will show available start up discs. Hopefully the OSX installer will show up as CD Icon. Select the Icon with your mouse or keyboard and press enter to start up with the Installer CD. From the installer you should be able to erase and format the drive as Mac OS Extended before installing OS X.
If the computer still won't boot from the CD double check that it is a retail OS X installer CD. If your CD has "software restore" or "ibook restore" or any other varient of restore written on the label; or if it names a particular model such as "ibook install" or "imac install" it is not a retail copy and may not be a bootable disc. A retail copy will only name the version of the operating system followed by the word install written on it's label and usually have a brief instruction on booting from the CD by holding the C key at startup.
If you can boot go to safe mode using F8, see if you can do system restore from start/programs/accessories/system tools.
If you cannot boot, or system restore does not work you need to reinstall Windows, either using recovery CD from Acer, or generic Windows disk. In last case you will need to reinstall driver after installing windows. If you do not format hard disk or delete partition, you will be able to recover your data (documents, pictures, music, desktop contacts etc) after installing Windows.
