Hi Starkley,
Thank you very much for all the help.
Finally i got the solution.

I installed a lot of anti viruses without any luck. Finally i un-installed all the anti viruses and then installed Avast - Home edition. This sorted the problem.Although no virus was caught as such.

Regards

Remove and then reinsert the video card is first step.

Does your motherboard include an onboard graphics card? If so, boot machine with video card removed and look at the system log to check for any error events. You may need to reinstall the drivers if they have become corrupt.

I have a blue and white padlock keeps showing up in the middle of my screen. Blinks on and off for a while then disappears, then comes back. On and on, very irritating.


It sounds like the DELL Capslock indicator. It is a light blue square with a lock on it and a capitol A under the hasp. You may have a bad keyboard key. switch out keyboards and see what happens.
Good luck,
James.

Says out of range when turned on


The default resolution for your video is set for some value the monitor can't support. You can try starting Windows in VGA mode. Press the F8 key several times when you turn the computer on and the manufacturer's logo screen appears. This will bring up the Windows startup menu and you can choose the VGA option. This starts Windows with video settings all monitors can handle so you can see your desktop. Then set some lower resolution and/or color depth. If you absolutely require the resolution your monitor can't handle, say for some game or graphics application, the only solution is to replace the monitor with one that can.

Red stripes on my monitor


This looks like a driver issue. Could be incompatible with a software you have installed or bad install.

Use a generic VGA to unintsall and reinstall driver for new card. Turn off computer and then install the new VGA. This should work.

Dell 1702FP 17" shows nothing after Radeon HD 2600 put in.


Is the card plugged into the (PCI/AGP) slot correctly? Did you disable the onboard video in the bios? Also be sure to check in windows device manager and check for the graphics card to appear there.

The two cards(Gforce Nvidia card) might not be compatible for your motherboard because they're for heavy graphics like playing games, and *********** board is old that you;ve mentioned. including the message memory range unavailable. Try using your old card with the new monitor.
