Anyway, When i start my computer up a pop up window comes up with 'isass.exe- unable to locate component' at the top then it says- This application failed to start becase themed32.dll was not found re-installing the application may fix the problem.
I cannot log into safe mode or anything, after the pop up comes up, the computer screen stays blank with just my desktop background picture on for about 5 minutes and then switches itself off.
Is there anyway i can fix this, bearing in mind that i have no idea about computers? Or should i just call in a professional ?
