Okay, I am usually pretty good about figuring out my own solution to things but this has kicked me in the butt. I recently purchased a Gateway DX4200-09 product page: http://www.gateway.com/systems/product/529668220.php

I then decided to upgrade the power supply and graphics card to a Sapphire Radeon HD 4850 W/ HDMI 512 mb. The problem I am having is repeated blue screen errors, if I have the vista provided radeon 4800 series driver applied i get the memory management blue screen and if i have the vista provided hd 4850 driver applied i get the atikmdag.sys blue screen. Neither driver is what i want but apparently all i can download off of the sapphire website is catalyst control center which doesn't update any drivers whatsoever and if it installs drivers they are nowhere to be found.

Please help me all i want is my actual driver on my computer not the vista provided ones!

I re-posted this because people seem to be coming here to talk more about ati "trying to hard" then assisting people with their issues.

The drivers are downloaded at the top right of the screen, it couldnt be easier.

 

Graphics/OS/Radeon/Radeon HD4800 series.

 

Personally I think that blue screening is indicative of a hardware error and not drivers. Chances are you will be RMA'ing that 4850, but give the official catalyst drivers a go first.

Yes, use the drivers from ATI, or the ones off the disk. Don't use the Microsoft Vista Drivers. Also, I assume you were using the onboard 3200 originally? If so, that is good because we won't have to worry about old NVidia drivers. Also, what was the new PSU you bought? Bluescreen errors can also be PSU. And yeah, that trying too hard thread was pretty pointless. If only half the effort were put into helping people, but oh well, these big video card releases are only once a year or so.

It was a 750 W Rosewill green series 80 plus certified. Definitely enough power to the system and a well rated PSU. I ended up RMA'ing the card and we will see. I have had the computer running without the card with absolutely zero errors so I think it is a pretty clear sign that the graphics card was the issue? Right?

Certainly plausible. My first 4850 was bad, but it had a short in it so it wouldn't even get to post. If the rest of the system is fine I guess it would have to be the card or the PSU (and yes, that PSU is enough if working correctly, it is possible it was damaged and can't work at higher load, but that is not likely). If you still have problems after RMA, I'd suggest doing a careful uninstall and reinstall of drivers or maybe (the most likely way to get results) a full reformat and reinstall.
