Monitor Problems

By egsiegmund ·
I am using an ASUS A7V8X mb and an AMD CPU. I had problems with an AGP 4X board - I got a blank screen. I then installed a PCI video card which I previously used in another computer. With the PCI board I got the ASUS logo screen and got into the CMOS/BIOS setup screen. I did a Save & Exit and got the Windows 98 logo screen then the screen went blank and in a few seconds I got a screenful of jumbled red lines like moving horizontal lines and what might be diagonal lines in the middle half of the screen.

Monitor Problems

by TheChas In reply to Monitor Problems

Here is what I suspect:

1. the AGP card was not fully seated in it's slot.
I have seen this so many times, that if in doubt, I automatically remove the bracket from the card and see if it seats deaper into the slot.

The AGP slot has interleaved pins, so the card only needs to be a little bit un-seated to not function.

2. Did you move a hard drive with W98 installed onto this system?
If so, you need to remove all the old drivers first, or you will have problems booting.

Start by seeing if you can boot into safe mode.
If you can, disable everything that you can, and remove any device you can from device manager.

Then boot with step by step confirmation.
DO NOT load any drivers for devices that are not present.

If you cannot boot into safe mode, or still have problems, boot from your W98 startup disk, insert your CD, and re-install Windows.
Then, install the correct device drivers starting with the drivers for the motherboard.

In the safe mode I disabled all drivers many of which wre not applicabe anyway. In safe mode I found that the screen resolution was set too high for my monitor. After that change I reinstalled the AGP card and it worked OK.

The resolution and refresh rate may be set too high for the PCI video card. Start up in safe mode, as TheChas suggested, and reset the video to Standard VGA. Next remove the drivers for the AGP video anmd restart the system. You should be able to install the drivers for the PCI card and set it the resolution that will not overtax the PCI video card.
Hope this helps
My experience with AGP cards not being fully seated resulted in three short beeps when the system was booted. Not all motherboardmay support this feature so it is a good suggestion to assure that the AGP card is fully seated.

As long as your sure your Asus MB works and the PCI card and monitor work (otherwise try another monitor or PCI card to get known working parts), then see if you can boot into safe mode using F8 at boot. In safemode, set the display properties to the lowest rez 640x480 and 16 color and reboot. If that works, slowly bump up the rez as much as it can handle. If none of that works try another PCI slot. You might also try looking thru the bios setup to see if there are any PCI slot or AGP slot config changes that need to be made. Hope some of this helps and good luck.
