Do hope this forum will help me to solve my problem.
My ProBook 4530s with Windows 8 pro 64-bit, occasionally freezes up for a second. not only music & videos but also Word and stuff, particlularly MS office 
pretty annoying when you're typing and there are missing some letters occasionally 
it happens more offen when i try to watch HD videos
I had the same issue, with win 7 pro 64 bit, but it was solved through this forum 
hoping the same now for my current issue
i am going crazy with this situation, plz help soon
