When you say it blinks, do you mean your screen goes black, or is it just flickering? If it is just flickering than chances are good you just need to turn up the Refresh Rate on your monitor. This is needed generally when higher resolutions are brought about. Right click on your Desktop, click the Settings tab, click Advanced, now you should see a tab called Monitor. In here look for the letters Hz, or the words Refresh Rate, and there should be a list you can open. In here increase your Refresh Rate to at least 85Hz. If that doesn't work, coooommmmeee on back!
