Video card install help

Deathstalker · Post by **Deathstalker** » 2008-04-25 07:25pm

My old card died, so I got a new one. However after installing the software, just before it gets to the Windows desktop, it cuts out and my monitor says no signal.

It is a Visiontek 256 MB 8x AGP card going into an ASUS P4T-E motherboard. My Alienware is six years old, but except for the card it runs fine and continues to soldier on.

I tried cleaning out the old Nvidia drivers, and hunted down Nvidia stuff in the Registry. I've tried both the disc and web drivers for the new card.

I'm looking for any and all ideas before I format and reinstall XP, but if it is hardware incompatibility then a reinstall will be a waste of time.

My laptop doesn't run WoW, and I haven't played in a week.

The Deathstalker will be indebted to whomever can help him.

Nothing's jumping out at me. Will it boot into safe mode? What's the actual model number of the video card?

The card works in that XP can use the generic VGA driver and everything works fine in Safe mode

The card is a Visiontek Radeon HD 2400 PRO

Ugh, radeon drivers. The Horror.

Set it to AGP4x in the bios and boot up with the drivers, and see if it still does it. I had an AGP8x card that was doing this and slowing the bus fixed it. If it does, go back and turn 8x back on, and disable sideband addressing, see if it still cuts output.

This sounds more like a driver issue then a hardware one (however, it doesn't exclude a hardware issue) - the monitor probably does the "no signal" routine do to being sent some incompatible mode. Seen such problems happen when switching from Ati to nVidia or back.

If you have a server or an external drive, perhaps doing a backup image to it and then reinstalling the computer to check if it really is a driver conflict would be the smart thing to do.

Just an update, I returned the ATI card and got an Nvidia based card and it worked on the first try. Of course my new flat panel has a bad pixel, but half a win is better than nothing.

I was going to ask how old your monitor is, but since it works now...

I got a flat panel to replace my five year old 19" beast. As I said the new flat panel has a bad pixel but it is up in the corner, and I threw the box out before i noticed it.

Don't most places require a certain number of dead pixels before they'll do anything about it?
