Perhaps you should try to clean the lens of your cd-rom with a cd cleaner or clean the cd that you are inserting to your cd rom...

you might have to physically unplug the plug you cd rom back in this should activate the found new harware wizard or you might try
make sure that the cd rom is getting enough power test all leads that are attached to the cd rom including electical extensions and make sure they have a secure connection or just replace them there might be bad/faulty or
your drivers may have been corrupted or you might have a virus run your antivrus program
you might have to physically unplug the leads for this cd rom then plug them back in this will activate found new hardware wizard or
you might have to uninstall then reinstall your cd rom or uninstall the driver then reinstall for this device
control panel admistrive tools,computer management,device manager scroll down cd dvd rom drives right click you can you can update driver,roll back driver,or select properties general

iat the time of boot a message as follows is displayed

maybe cd lens is damaged in which case u may need to change the drive itself

first find the cd/dvd of the OS then go to BIOS choose first boot device to (your cd/dvd rom) then put the cd in the cd rom and install itit will solve the problem

your problem is very clear... your cd-rom is corrupted.. install new windows... NOTE-do this only if your cd drive is NOT displayed in my computer..
please vote for me...im sure this will solve your problem...

You need to go to the website of whoever made the motherboard and get the BIOS flash utility and the BIOS binary file to update your BIOS. Make sure you get the right one, as using the wrong one can render your motherboard worthless. The BIOS file has to be the exact match. There is no such thing as close in this situation.
If you are not sure of the exact make and model, get te free Belarc Advisor from http://www.belarc.com
The BIOS chip holds information about your motherboard hardware. It is reprogrammable. It uses what is known electrically erasable read only memory. This is also called Flash memory. Reprogramming is called flashing. When you flash the BIOS, all data is erased, then the new data is written. The flash utility will most likely allow you to save the old contents, but you might have an extremely tough time recovering from an improper flash. You'll also probably need a couple of floppy disks, one of which may have to be bootable. If you need a bootable floppy disk, you can get an image file from http://www.bootdisk.com.

Go into the computers bios at startup .
is the cd rom drive enabled and detected .
if not then open the case and check the cables to cd
