Okay Guy’s and Girls, here’s my first post. I’m a newbie at posting but not a newbie with computers, although I’m not an expert by any means. This question has been asked a thousand times (please don’t think I’ve not done my homework on this) I’ve checked lots of forums and googled until I’m googled out. First Computer Specs; MoBo, Asus K8V using 64/32 bit architecture, Socket 754 CPU, AMD Athlon 3000+ 64 bit O/S, Quad Boot, Win XP Pro SP2 Win XP Pro SP1 (OEM x64 Edition) DOS Win Recovery Console Chip Set, VIA K8T800-VIA VT8237 Memory, 1024Mb Kingston DDR SDRAM PC3200 400Mhz HDD, O/S #1, (Win x86), Maxtor UDMA-6 (ATA-133) 250 Gig, 16Mb Buffer HDD, O/S #2, (Win x64), SATA WD Raptor, 37 Gig 10K RPM Other Storage, (2) HDD, Seagate 120 Gig RAID 0 <> (1) HDD, WD Caviar 200 Gig P/S, 500 W ATX (Ultra) Sound, Integrated (VIA AC'97) ---------------------------- Video; These cards work S3 Vision 968 - 2 Mb onboard (PCI) Driver Rev 1995 Diamond Viper II - (PCI) Driver Rev 1995 Video; These cards are a problem ATI Radeon 9200 LE (AGP) 8X 128 Mb ATI Radeon 9550 (AGP) 8X 256Mb XFX GeForce FX 5700 LE (AGP) 8X 256 Mb XFX GEForce FX 5200 (AGP) 8X 128Mb MoBo has no integrated graphic drivers. ---------------------------- I’m going to make this as informative and short as possible. Problem; When I install the above video "PCI" cards, the computer recognizes and installs the driver with no intervention from the operator. Computer runs great, no problems except, as you might expect, I don’t want the PCI cards in there. I’ve got several ISA video cards, if I had a slot I’m sure they’d work also. "AGP" cards give me a blank screen, and most (but not all) of the time the CPU runs (by the LED indicator) wide open. The only way to get out is to “On – Off switch shut-down”. This is a short synopsis what I’ve done; (1) Boot up using PCI card. Go to “Add-Remove” to make sure all vid drivers are gone. Go to “Device Mgr” and delete PCI driver. Set screen resolution to 800x600 and colors to 16 or 8 bit. Unplug NIC. (2) Restart and boot into Safe Mode. Log in as Admin. Check to be sure drivers are still deleted. Open MSCONFIG and set it to boot using “Safe-Mode”. Run “Driver Cleaner”. (3) Restart booting into Safe Mode, Log-In as Admin. Computer will state “hdwr installed, restart to finish installation”. Check to see if adaptor in “Display Screen” is listed as VGASave. Check to see if MSCONFIG is still set to boot into Safe. (4) Restart and boot into Safe Mode to finish installation of VGASave. (5) Shut down computer. Remove PCI card and install AGP card. (6) Monitor now works. Boot into Safe mode, Log in. Hdwr Wiz will execute. Install video driver and…. Hdwr Wiz will tell you to reboot. (7) Re-Boot into Safe Mode again. Check all properties, i.e., (a)Everest now says AGP “ENABLED” (b)Device Mgr now lists driver as “RADEON xxxx” (c)Video Adaptor now says “RADEON xxxx” CONTINUING: Go to MSCONFIG and uncheck boot into Safe Mode. Restart and boot into Windows XP. Hope I didn’t miss anything. NOW… After about 2-3 minutes screen goes blank again. Back to square one. The ONLY way I can get a screen is to uninstall the AGP card and re-install the PCI card which re-sets the driver back to “S3Vision 968” the instant the program goes into Windows. Over and over we go… I’ve had the MoBo out of case and booted up. I’ve had all peripherals removed and replaced. I’ve disconnected power from 3 HDD, Fans, and lights. I’ve tried the AGP’s in other computers. I've checked memory. I’ve tried everything I can think of. I’m ready to buy a new MoBo, because I think I’ve got a bad AGP plug-in socket. Also note that I’ve had minor problems with the computer from day one. I had always attributed it to the Beta O/S and all the Beta drivers installed. But little quirks were always popping up and getting worse as time went on. Sorry for making this so long but I felt that it was necessary if anyone could help. Thanks a lot… BadDog,Bad!
