I am Vassilis from Athens, too and experiencing random freezing problems with my 751h, as I have already mentioned in a previous post. That's a nice tip you describe general_78, but I will not even try it, at least not yet. GPU hardware acceleration is crucial for this weak netbook, since the CPU is not powerful enough to catch up with decoding e.g. video files.I've never heard that it could be a DMA problem with the graphics subsystem, I always thought it was a hardware problem that had to do with overheating or collapsing under heavy pressure. Anyway, I am still waiting for a reply from Acer, after I provided them my netbook's serial number and they should check out some things (haven't told me though). Freezing is a fact, unfortunately, and I hope that the tech support will soon find a solution. :evil:
