I Have a PCChips SiS A31G MotherBoard (MB). It has an onboard integrated video chip SiS Mirage. I HATE it, it's weak and can barely keep up with 2005/06 games, let alone even have a wet dream of coping with COD4 or Mass Effect. I have an AGP card ATI Radeon X800 256 MB Pro and am trying to get it hooked up, but when I installed it and hooked the VGA (yes, VGA. I don't have DVI yet but it supports it which makes me happy for the future.. If I can get the [bleep] THING WORKING!) port into the card, I look up at my monitor and.. Nothing. I get nothing at all. I enabled Dual Monitor Support in BIOS, and can't find the option to disable onboard video, but I don't think on-board video would conflict with the AGP slot and cause it not even to detect any hardware installed (I tried checking to see if it was even detected in Device Manager and it's not there at all). I know the X800 works cause it was my fathers and he gave it to me. The MB is not new, but I never tried to use a card on it before. I don't know if the AGP slot is bad, cause I don't have any other cards right now, but at the same time even if the onboard video was enabled it would still detect the X800 right? I'm slightly infuriated and a bit concerned about if the AGP is bad, how long till the PCI slots [bleep] out. I re-installed all the ChipSet drivers thinking that COULD have been the problem and updated the Drivers from their website. One thing that confuses me, is in the device manager, I have it viewed by Device Connection to see if I can find the AGP Bus, and all I could find close to AGP was in the PCI Bus.. It goes
PCI Bus > SiS Accelerated Graphics Port > SiS Mirage Graphics > Plug and Play Monitor.
What the...!? I'm thinking this COULD have something to do with this all and maybe my AGP slot isn't bad, but ..Not Enabled?? and I'm confused with this whole thing. The card works on my dad's machine, but I can't figure it out on mine. This is my MotherBoard
and this is my Video Card
. Sorry for the C-Net review, couldn't find any other link that resembled my card so closely. Can someone please give me some clues here. I need to know if I need to disable my Onboard video JUST to get my AGP slot to work, as ridiculous as it sounds, I can't think of any other thing it could be, (other than a bad AGP slot, and if so, is there any other way to test it other than a different AGP card.) and if that's my problem then how would I disable the on-board video. I can't really find a jumper for it, and their manual is pretty much useless. HELP ME!!
