this is probably your screen refresh rate is too high.try booting the computer in vga mode and lower your default screen refresh rate.if it fails try with a older driver. the problem might be due to overheating. try cleaning your cabinet and install a new heatsink and apply new thermal paste on your vram chips.

In this case you have to do the PC restore . you can do that in dell machines by shutting down the machine and when it is coming back on just HOLD DOWN THE CTRL ket and the START HITTING f11 key in this case you will lose the data which you have the on the c drive but this issue will get resolved .
Else you can try to restart in the safe mode with networking and then go to the system restore and then select the bold dates in which you have idea you system was working fine . selct the date and then do the system restore . In this case you will not lose the data but you will lose the updates which you have done after that date .
in both the cases system will work .

You could have a defective screen - a defective inverter or a CCFL lamp, follow this to determine the fault.
To determine if you have a LCD screen problem, read this and follow the instructions.
Defective CCFL backlight, it may have the following symptom:
Connect an external monitor to your laptop and power it up, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight.
Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

These machines have a terrible overheating problem! You will have to clean the fan opening and, put sylicon grease on the heat pipe and, heatsink that covers the cpu

Insert the original Windows CD-ROM into the DVD-drive, and see if the computer will "boot" from that disk. If so, then it could be your 'C:' drive which is having the problem, and thus not "booting" your computer from it.
