Where do I begin? Alright, to start things off:

• DX4850-27eu

• Windows 7 Home Premium 64-bit

• i5-2300 at 2.8GHz

• 6GB RAM

• 300W PSU

• Sapphire HD 7750 1GB GDDR5

I've been using this computer for awhile now, and just recently, I decided to purchase a dedicated GPU for it, as the Intel HD is quite slow when it comes to games and such. I went with the 7750 because it has a low power usage, and it doesn't require axillary power; it draws it directly from the PCIe slot.

It came in the mail yesterday. I plugged her in to the PCIe slot (my computer only has one), put everything back together, and turned on the computer. Next, I had to install the correct drivers for it to work. I uninstalled the drivers for Intel HD, went to the AMD website, picked the GPU I have, and downloaded Catalyst. So far, so good.

So this is where I started having my first issues. I 'installed' Catalyst, picked custom install, and went through the necessary downloads. At the end, it said installation complete, but warnings occurred during installation. This is the warning that occurred:

<?xml version="1.0"?> <?xml-stylesheet type="text/xsl" href="Report.xml.xsl"?> <monetreport xmlns:dt="urn:schemas-microsoft-com:datatypes"> <general> <cmdline>-UI </cmdline> <time>09/06/14 13:02:20</time> <action>install</action> <download></download> </general> <dcm> </dcm> <exist> <package> <description>AMD Catalyst Install Manager</description> <result></result> <version>3.0.868.0</version> <size>20 </size> </package> <package> <description>AMD APP SDK Runtime</description> <result></result> <version>10.0.898.1</version> <size>90 </size> </package> </exist> <install> <package> <description>AMD Catalyst Install Manager</description> <result>Succeed</result> <version>3.0.868.0</version> <size>20 </size> </package> </install> <uninstall> </uninstall> <downloaded> </downloaded> <resource> <hwinfo>Hardware information</hwinfo> <existpkg>Existing packages</existpkg> <pkg2inst>Packages for install</pkg2inst> <pkg2uninst>Packages for uninstall</pkg2uninst> <otherdev>Other detected devices</otherdev> <errmsg>Error messages</errmsg> <name>Name</name> <manufacture>Manufacturer</manufacture> <chiptype>Chip type</chiptype> <chipid>Device ID</chipid> <otherhw>Other hardware</otherhw> <download>Download packages</download> <succeed>Success</succeed> <fail>Fail</fail> <vendorid>Vendor ID</vendorid> <classcode>Class Code</classcode> <revisionid>Revision ID</revisionid> <ssid>Subsystem ID</ssid> <ssvid>Subsystem vendor ID</ssvid> <header1>Catalyst™ Install Manager</header1> <header2>Installation Report</header2> <finalstatus>Final Status:</finalstatus> <versionofitem>Version of Item:</versionofitem> <size>Size:</size> <bytes>Mbytes</bytes> </resource> </monetreport>

I then try to run Catalyst, as it should be on my computer, but I can't even find it. So, I go to the AMD website, and attempt to look for help. I realized that my HDMI cable is still plugged in to the mobo(?), so I unplugged it, and plugged it into the HDMI port on the GPU. Nothing appears on the screen.

I also downloaded GPU-Z, to see if my computer even detects the card. All I see is 'Video Controller (VGA Compatible)'. I went into Device Manager, and it says the same thing under 'Display Adapters'.

Other things I have tried, to no prevail:

• Re-seat the graphics card itself.

• Launch into safe mode, uninstall all GPU drivers with 'Display Driver Uninstaller', then reinstall Catalyst.

• Open up the BIOS, and try to find something about it in there. Maybe I'm missing something?

This is my first time installing a graphics card, and I'm getting frustrated that I can't seem to figure out the problem. If there is anything else I need to make clear, please ask. Any help would be greatly appreciated. Thanks!
