Monitor frequency too high.

[Grimm]

I just installed Windows XP Pro. I am having trouble with setting the monitor frequency on the graphics board. After the installation, on its 1st boot, the system boots with the graphics adapter sending on a frequency that is too high for any monitor I could try. After booting in VGA mode (or Safe mode) I discovered some strange things. First, the display settings said "ATI All-In-Wonder on Dual Monitor". I don´t have 2 monitors and ATI AIW does not support 2 monitors (it only has 1 connector). I checked on the devices tab and found that windows had installed to monitors (Standard Monitor(s)). I also found out that the display settings was set for 60Hz, but when I boot in normal mode no monitor I tried was able to display any image (all responses were Frequency Out of Range). I tried some remedies. 1st I tried uninstalling the 2nd monitor, but that had no effect. Display settings still showed Dual Monitor settings (one being standard monitor the other being blank). I tried changing frequency but that had no effect. I installed the latest video drivers (catalyst and etc) but after booting the problem persisted and, when in safe or vga mode, it showed the drivers where not installed. I installed the motherboard´s latest drivers (VIA Hyperion),. I updated the BIOS. I am confident that the video board is functioning since it was previously installed on a almost similar system and it was working fine. My system is:

Athlon 650 Mhz
Asus A7V-RM mother board
256 Mb, 133 Mhz
ATI All-In-Wonder Radeon

I would appriciate some help.

Thanks

Best thing to do is start with a clean sheet

In Safe Mode ...

Uninstall the ATI drivers and all it's associated software.

Remove the card from Device Manager.

Reboot and install driver as instructed by ATI.

I'll second that.
