hello,

i have a new 19inch lcd tv monitor connected to my pc and each time the pc boots during the windows vista loading screen monitor displays PC 640 * 480 and then the screen goes blank with a "no signal" message ,

its worth noting that
i. even though the screen gives this "no signal" message and seems to switch off the pc seems to continue booting and loggin in as the windows welcome sound can be heard
ii. i do not encounter any problems of this nature when i boot in using safe mode, everything displays just fine
iii. this setup works just fine if i use my alternate hdd which has windows xp pro sp3

Please assist, what may be the problem and how do i resolve it

Thank you
Hi mirthon,

As you have mentioned the no signal message comes only after the Windows Logo, this can possibly happen because of a faulty video card driver. Follow the steps below to uninstall/install the video card drivers:

1. Power on/Restart the computer.
2. Once the computer goes past the initial setup screen start tapping the F8 key on the keyboard.
3. It will show you Advanced Boot Options.
4. Select Safe Mode and hit Enter.
5. After loading some initial drivers the computer will show you the Desktop with a low resolution. While you are still in Safe Mode uninstall/install the Video card driver.
6. If you need any help with the video card driver installation, do reply with the Device instance ID of the video card driver.
7. To get the Device instance ID of the video card, right click the Computer/My Computer icon on the Desktop, select Manage, select Device Manager under Computer Management from the left pane, then expand Display Adapter from right pane. Right click the Device listed under Display Adapters, click properties, go to the Details tab, and then select Device Instance Id from the dropdown list. Make a note of this Device Instance ID.

Do reply with results.
