Windows 7 - Ati radeon hd 4850

I'm running Windows 7 Pro x32bit with 4GB RAM and an AMD Athlon 64 X2 DCP 4400+, 2200 Mhz. My Samsung SyncMaster 2443 uses an ATI Radeon Xpress Series (0x5954) Adapter and is uninstalled when it's time to install the proper drivers/software for the ATI RADEON HD 4850 Graphics Card (PCIe). After the reboot if I get a screen at all, it's effected by the weight of the card itself and must be adjusted by hand until the "green" goes away. After that is taken care of, within 5 minutes I get the BSOD!!! The Blue Screen Of Death informs me that a recent change to the Graphics card or adapter caused the problem. The computer is beyond the system requirements and should work fine, right? Any suggestions on how to handle this, steps to try or something I'm just outright forgetting here?

Thanks in advance any help that you can provide!

hi x51shadow, and welcome to sevenforums,

er, i think you are missing a poll option (or maybe two).

how about 'no - never had a problem with it?'

i used to have one and it worked great. at the time it was an absolute bargain, and i loved it. i only upgraded to a 4890 after i bought a 1920x1080 monitor, and found the 4850 didn't quite have enough oomph to push all those pixels about.

i sold it to a friend and he's still happy playing modern games with it on his smaller monitor.

x51shadow, full system specs of the computer in question would help.

Also did you remember to connect the 6 pin (3x2) power connector on the card to the power supply? And is the power supply strong enough for that card (make and model of the power supply would help)?

I have one, and I'm going to sell it soon since I upgraded, but it has been a great card for me. Some of your system details don't make sense...like the ATI Xpress card. First off, the monitor doesn't add this...it is in the system somehow...possibly on board the mobo. See if that can be disabled, as it may be causing a conflict. Or, load the drivers for it anyway, even if the monitor is connected to your 4850.

If you are getting a BSoD, write down the codes and do some searching on them. That will likely tell you if the problem is a software conflict or a bad card.

Sounds like he has a conflict. Most AMD MB have built in graphics. He probably needs to go into bios and tell bios whether to use the IGP or the card.

I have never had a problem with the HD 4850. I have owned it for over 2 years.

It sounds to me like it is not properly seated and locked into place. Also, a power supply of 450 is really needed.

One or two things not enough amps also check the onboard some auto disable some don't also if there is conflict errors Bsod's it is ussually the hardware is not functioning correctly either bad card or just not enough get up from the other system parts involved

I'm using a Thermaltake TR2 430W PSU. The GC is powered via a 6-Pin PCI-E power connector. The Xpress 200 is automatically installed when the monitor is connected. I'll post the BSoD codes later tonight. I do uninstall the Xpress 200 before installing the 4850, so I'm not sure if there's a conflict with the computer trying to automatically install it again. I'll atempt to disable the on board graphics through bios again. I'm using an HP dx5150 MT. The 4850 is 512MB GDDR3.

Also, sorry about the poll. It was my first post and wasn't quite sure what it was about. Can someone tell me how to delete it?
