This seems to be a very common problem with no solved answers. I really hope that it isn't a hardware problem, and judging by the large amount of freezing problems on other products, I doubt it.
My model is the Aspire V5-552PG, and I've contacted Acer support already - They sent me a BIOS update and the newest network driver that they had, but it did NOT work. I'm still getting random freezes! Sometimes it's every 5 minutes, sometimes I can go on for days without any freezes at all.
It seems to happen more often if I use the internet, and usually within loading a page. The only solution is a hard reset, anything else does NOT respond.
If anyone has a solution, please give it to me. I really don't want to resort to delivering this for repair...
Best regards,
Ben
