Hi,
I had bought the Acer Aspire S7 392 in October this year from digitec.ch AG here in Switzerland. Everything was working well until 19th December when my McAfee Antivirus expired and I decided to change my antivirus to Comodo Internet Security. A month back, I had installed Windows 8.1 as well and things were running smoothly until last night. Last night, when I installed Comodo Internet Security, the computer requested a reboot, which I did, and then my computer went blank. I could not even reach the Acer logo at the startup.
As I tried to check the details regading this blank screen problem, Irealized that a lot of people are suffering from a similar problem. It seems that Windows 8.1 and a installation of a new antivirus may have lead to this blank screen problem. Also, it seems to be a bios problem as the computer would not start and I am hoping of anyone could help me in sorting this problem out.
