So many computer face this blue screen fetal errors on windows.

This error comes usually when there is problem in software or driver compatibility issue with hardware or operating system.
Also this error comes when there is bed indexing unit in hard drive.
You can solve this errors with following 2 methods.
(1)When you power up the computer press F8 key then enter in safe mode.
Then if you are able to enter in safe mode then uninstall driver or software which you installed recently and face this error.
(2)If you are not able to enter in safe mode Then you need to fix error on hard drive.For that you need windows disk or recovery disk.
Boot your computer with that disk
For that when you power up the computer press F1 or F2 "del" key to enter in bios.
Then go to boot menu and set first boot device as your cd or dvd rom.
Then save settings and exit bios.
Insert windows disk in cd /dvd rom.
Then it boot with that disk.Then you get this message "Press any key to boot from cd.."
Then press any key.
Then follow the procedure then enter in recovery console mode then type in prompt "chkdsk /r"

Then it fix error on hard drive.
Then check if again you are not able to enter in windows then boot again and this time choose "R" option for repair previous windows " then it repairs old windows then it loads again old windows.

Ill try to help, in this cases..maybe your optic DVD rom cables may have weak or poor. Its usually common at DVD or cd rom.

Hi Tony,
Thanks for the details you have mentioned. The steps you have taken are correct and if the System/ hardware is ok, it should boot from CD Drive. Whenever i have faced such an issue, i always started afresh to check each hardware (CD, DVD, ROM, Hard Disk, Cables, Connections etc) and most of the times the issue was optical drive or CD/DVDs.

So, I recommend that make sure that the CD/DVD ROM is functioning properly. When the system is set to boot from CD/DVD, it must try to read CD/DVD after power on. It is indicated by spinning of the optical drive and blinking CD ROM LED. If there is a bootable CD in the drive, it should boot. You may try to boot the system through DOS bootable CD. Also, if you still have the OS on your system, you may check the CD ROM through windows.

Let me know if any further clarification/ assistance is required.

GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

Use DVD rom in DVD not CDROM it's only for CD.

It sounds like you need to replace the DVD Rom itself.
They do go bad without warning.
A DVD Rom is not that expensive and should take about 5 min to replace rather easy job.
Happy Holidays

use this tool to reset the cd in the registry
after you run the file - reboot the computer -
