Note: I am not very tech savvy so bear with me:

Hi, I was trying to instal TERA online and could not get it to work, so I tried updating my graphics drivers. I have a ati radeon HD 5700 series, and I updated via the automatic updater. I got a blue screen and I think it never got to finish.

After the automatic reboot my resolution was changed to 800x600 and I am not able to get it back up higher than 1600x1200 which makes my screen look weird.

Also I got an error message that the driver was not working on boot, I tried to reinstall the driver but the automatic updater says that it is already up to date.

I get that somethings amiss with my graphics driver. I tried googling for help but all I get is a maze of graphic driver difficulties that are only loosely related to my problem.

Some information about my system:

Graphics Card

ATI Radeon HD 5700 Series

AMD Catalyst Driver Version, and Driver History

I am not sure where to find this, I tried installing the latest. I bought the computer 2-3 years ago and I think it came with updated drivers. I have updated it about 2-3 times in this period.

Operating System

Windows Home Premium  7 64 bit with service pack 1 installed.

Motherboard or System Make & Model

I don't know, I have installed CPU-Z and on the mainboard page it says the following:

ASUSTeK Computer INC. P7P55-M

Power Supply

I don't know, and I don't  know where to find this.

Display Device(s) and Connection(s) Used

Samsung hdtv monitor  Syncmaster LD220HD, connections used are a HDMI cable and a standard power cable that got delivered with the TV.

Applications and Games

Haven't even tested games yet as it cannot even run windows without a messed up resolution.

CPU Details

Intel Core i7 860 2.80GHz no overclock

Motherboard BIOS Version

American Megatrends Inc. version 0705 from 03/31/2010

System Memory Type & Amount

4096 MB DDR3 don't know the manufacturer.

Additional Hardware

None as far as I know

Additional Details

- I've scanned for virusses like a week ago using Microsoft Security Essentials, I haven't had  viruses or spyware for months.

- Haven't done any other checks as I do not know much of computers.

I hope this is enough information, I will try my best to give more if it is neccesary.

My gratitude in advance,

Bob

I think you should try a clean install of your graphics suite. Here is one way to do it > http://forums.amd.com/game/messageview.cfm?catid=444&threadid=162444&enterthread=y  pay special attention to the .netframeworks requirement for latest drivers and update if necessary before trying to install the new drivers.

Also, don't use the auto-install thing. Follow steps 1-4 and download drivers. http://support.amd.com/us/gpudownload/Pages/index.aspx
