I tried re installing Windows but it won't boot from the CD.
I just want to be clear about what you are doing
You say in your other thread that the screen is black (in Windows Normal mode)
And the reply back was to re-install Windows! As it may be a Virus! And you asked around and others said the same!
And now your Windows CD
disc does not boot.
Well I don't. Although you may actually have a Virus (who knows) it's unlikely it's causing a black screen in Windows.
Now I know this thread is about "Disc" (as you say) but please try this first.
Turn on your computer
Repeatedly press the
F8 key on your keyboard
Select Safe Mode
Log on to your Administrator account
In Safe Mode Windows (a reduced functionality of Normal Mode Windows) do this:
Open Device Manager ie Start->Run->
Devmgmt.msc
Click on the + sign against "Display Adapters"
Right click on your actual Display adapter device, that it expands to
Select un-install (it may say remove or delete) Do this.
When your Display Adapter device is fully removed. Restart normally
Does Display now work in Normal Mode? (By the way, you may need to download the drivers for your Video card. Your specs presently unknown!)
