HD7770 problems

[Petrolhead]

Have an ATI HD7770

Computer running windows 7 64bit

When it wakes from sleep sometine text is blocked out with back bars, sometime it wakes up but all I have is a black screen

Any suggestion as to why this is happening (If I log off and on again its sorted)

Ah well there is another problem, everytime I download the latest drivers I get a security alert and they are deleted

I am using MS security Essentials

maybe its not MSE

I am using IE9 and when the download completes its scanned and I get the following at the bottom of IE:

OK, installed Firefox and got no errors however when I run the install I get a NSIS error:

Installer integrity chack has failed

I then tried renaming the file to install.exe and ran it in a command prompt with the switch /NCRC

The install started and then failed with the error:
Error decompressing data! Corrupted installer

I then downloaded the file using my MAC and copird onto my PC, same problem

I then downloaded the 32bit version and that was fine however it will not install as its says I need the 64bit version

Grrrrrrrrrr
