Colif :
Are you downloading drivers from :
http://support.amd.com/en-us/kb-articles/Pages/AMD-Radeon-7000-Series-Drivers.aspx
HD 7750 uses legacy drivers which are made to match every card prior to a certain model, so they aren't made to match that card specifically
Can you download and run
who crashed - it will give us a glimpse of the errors you getting and might help us solve them
Copy/paste summary in here and I see what I can do
though good chance we know what caused the TDR error.
Thank you for the reply
and yes that is where I obtained the drivers for the hd 7750
