Cannot display Video Mode on startup

When i restart or boot up my computer, my monitor says "Cannot Display this video Mode" It says this during the Bios and the Windows screen when the bar is loading. But when it gets to the login screen, the picture comes up on my monitor. I have a ATI Radeon X700 Pro as my graphics card and a Dell Dimension 8300 as my computer. It only turns back to normal if i delete the video driver for the video card. The only way i can access the bios is by using my TV(S-video out). I can use this way, but not permanently because of the bad graphics and no sharpness so it is hard to see.
Thanks.
 
Many video cards only support up to 75htz. When you remove the drivers the card is no longer active where you then see only the basic Windows vga drivers in use. It sounds like the bios setting is higher then the card can support or lower then needed. Look in the bios to see if it is set to auto or at least 60htz. One reason you may see the desktop without drivers installed may be due to having the wrong ones. You can go to ATI's support site to download the correct drivers and Catalyst Control Center if you use that.
 
Do you have another monitor you could try? Once, I had an LCD that did something similar. It worked fine on basically all but one resolution. It wasn't always like that either. After a few months, the monitor wouldn't display anything(besides Video mode unsupported)
 
One thing I just came across about that model at ATI is:
"ATI Customer Care > Solve a Problem > Display >

RADEON X700 - Monitor cycles on and off or appears to blink

The information in this article applies to the following configuration(s):
RADEON X700 PRO
DVI or VGA enabled monitor
Users with the above configuration may experience loss of video signal, intermittent display flicker or monitor turning on/off after running the system for an undetermined period of time.

If you experience the above symptoms then try adjusting the refresh rate for the monitor. Follow these steps:

Click Start menu
Open the Control Panel
Click Display
Select Settings tab
Click the Advanced button
Select the Monitor tab
Under Monitor Settings set the screen refresh rate to a higher frequency
Apply the settings" https://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&folderID=293
The last update for that model card is available at https://support.ati.com/ics/support/default.asp?deptID=894&task=knowledge&folderID=293 You may want to go with the Control Panel and WDM driver set over the Catalyst for less issues with gaming.
