Hi Emm I am no computer expert: * with a new motherboard did you have to change operating systems? * were you able to re-use your hard drive? if so can you go to a restore point when it worked? * have you installed all the drivers for your computer - like the monitor driver or video card driver? * are you viewing through a virtual computer or using 32 bit w7 or w8? * is the font installed on your computer? * did you press control++? Sorry no immediate solution but someone else might have a solution. Cheers Robyn
