Question about Dell Computers & Internet
Once in awhile when I turn on ,the screen is grey and you can hear widows starting.Other times it starts up fine.Is it the vidio card?
It does sound like a video card driver issue. Unfortunately, Dell does not have any Windows 7 drivers for the Latitude D620. You would need to look on the video card mfg. website for any Windows 7 drivers.

Either the LCD inverter or the LCD or, at the very least, the backlight in the LCD, is faulty. You will need to replace either your LCD inverter or the screen itself.

I don't know about that particular laptop but it sounds like a loose connection between mainboard and screen plus a bad inverter (regulates and supplies voltage to the actual screen from the main power source). Laptops typically have the inverter hidden somewhere in the frame that surrounds the actual lcd screen. Sometimes this regulator is part of a small circuit board, sometimes it is not (I suppose it might be part of the actual lcd in some cases, but i've never seen that). I would investigate things further in that direction and just hope your lcd itself isnt bad.

Did you upgrade the RAM when you upgraded to Vista. The D620 does not have the resources to run vista as pre-configured and requires, at the least, a memory upgrade. 1gb or greater is recommended.
Please upgrade the ram, or try F8 during boot for Safe-Mode and see if your RAM is not the issue. To check the amount of RAM you have:
Press and Hold Windows Key + PauseBreak
If you still have 256mb or 512mb vista is likely to barely crawl.

Tips for a great answer:
Please go through the below step, you can able to do it.
1) Shut down the Dell Latitude D620 if it's currently powered on. Click "Start" in the left-hand corner of the screen to access Windows' shut down options. Alternatively, press and hold the Latitude's power button, located on the top edge of the laptop's keyboard.
2) Turn on the computer by pressing the laptop's power button.
3) Press and hold "F8" on the top of the laptop's keyboard immediately after turning the computer on. If the Windows logo appears on the screen, you're too late and must repeat Steps 1 through 3 again. If you pressed it in time, a list of text options will appear on the screen.
4) Use your keyboard's arrow keys to scroll down to "Repair Your Computer." Push the "Enter" key on your keyboard.
5) Choose a language from the next list and select "Next." If you've password-protected your laptop, you will be prompted to enter your user name and password at this time.
6) Press "Dell Factory Image Restore." A new window will appear. Click "Next" and select the option for reformatting the hard drive and restoring the factory condition of the laptop.
