Author	Topic: Wierd AGP failure
Pish-Tush Maximum Newbie Posts: 17 From: Birmingham UK Registered: Dec 2001	posted April 25, 2002 09:20 If it happens once its probably cosmic-rays or somesuch, but twice suggests there's something going on! On two occasions now, I've come across PC's which have had apparent video card failures following major surgery. There's just a nasty beep sequence, nothing at all on the monitor though the disk drives churn indicating it's trying to boot. Taking the card out and reseating it does no good. So in each case I've tried an old PCI video card which works fine. But (now for the wierd bit) one replacing the AGP card and trying again it works. Two totally different boxes (different motherboards, video cards and operating systems) same effect. My guess is that the AGP controller and the BIOS can get into some wierd state that is only cleared by booting with a PCI video card. Anyone think this is plausible -- if so I guess the moral is don't dump your old PCI video cards. ------------------ And I am right And you are right And all is right--too-looral-lay IP: Logged

I am assuming by major surgery you are referring to major configuration/hardware changes and if so then anything can be affected. I'm not a wiz with bios settings but I have had similar conflicts before, and on taking the hardware out, removing the drivers/software and then reinstalling the entire thing the problem was fixed. It's never happened with a video card for me, but shrug yes having a pci video card around would be very helpful in this situation. Although I imagine most people aren't geeks like us with spare hardware laying around the room(or neatly tucked away in their anti-static bags for all you anal retentive types ) ~Thom ------------------ I just came in to use the bathroom.....

Lex Super Geek Posts: 200 From: University of Florida Registered: Jul 2001	posted April 26, 2002 19:47 Sounds like a static problem. It isn't too rare to find that you have to yank out the power cable or reseat a card or two before you can get a computer to boot right once you've been messing around inside it. IP: Logged
SupportGoddess Highlie Posts: 554 From: The Digital Temple Registered: Jul 2001	posted April 28, 2002 08:52 I had a display issue a while back, and was fully convinced it was the video card. However, what happened was that I needed to reseat my RAM. Try reseating some other things as well. If you keep seeing failures with it, there may be something else going on and the video display issues are just a symptom, not part of the actual problem. If you are getting beep codes, they might be listed in either your motherboard manual or on your manufacturer's web site. ------------------ "Programming is like sex: one mistake and you have to support it for the rest of your life." -Michael Sinz IP: Logged
ilovemydualg4 Geek Larva Posts: 23 From: Registered: Mar 2002	posted May 01, 2002 03:23 Are you sure that the card is compatible with the machine? (not to state the obvious, but someone has to ) ------------------ IP: Logged
