ATI Card Issues/Slot possibly..maybe mobo??

[JoshS24]

Hey guys, new to the forum. I picked up a Radeon 9550 AGP 128MB Card earlier today. Had GeForce 4 MX440 in here before. Installed the Radeon, turned on the comp..just got the monitor test. So, before I got all pissy, I took the card out, put the GeForce back in, same result. So, close to freaking out, I plugged the monitor into my onboard card. EVerything came up. I figured my AGP Slot was screwed, took the card back, picked up an ATI Radeon 9250 256MB PCI card. Installed it, same freaking result as the other two cards, no dice. I don't know what is wrong, i disabled the onboard graphics. I am using an older comp. Its about 4 years old. Its a Compaq Presario(great stuff, jk). I know its not an amazing comp but, is it too dated for these newer cards? Running an AMD Althlon Processor 1.3ghz, 512 MB Ram, windows XP, everything checks out for the requirments on the box. Anyone know what the hell might be going on? I'm inches from a core meltdown here.

I'm willing to bet it's a driver conflict between the driver for the nvidia and the ati cards......sounds like you need to boot with the onboard graphics, run a removal of both graphics drivers, and then reboot with the onboard graphics disabled and let it set up the new card. Should fix ya right up. Hope that helps. Oops, just gave it some more thought, (didn't think that response totally through) prolly graphics setting in the bios needs changed to slot your using? Forgive me, kinda late to be thinkin.......lol

Hey, how do i change the settings in the bios? i'm not sure how to do that stuff. if it is something simple, then i could probably do it. I will try driver cleaner to get the driver situation figured out, if that works, ill let you know.

its really easy just boot your computer up and hold down the
delete key some bios you use F1 key to enter setup
on start up

after you load windows delete all display drivers by way of
control panel than use drive cleaner pro to delete any left
over files

shut computer off and install new card ;reboot install drivers from disk
after windows loads
