Hi there,
I bought an Acer Aspire e1-571g (i5-3210M 2.5GHz, GT 620m 1gb, 4gb ddr3, 500gb hdd) in 2013 and I haven't any problems with it until now.
The laptop starts with a lag, ~30s up to 1m to boot bios and show me manufacturer name. If I restart it or shutdown and power on, it doesn't start at all, coolers work, everything work but I have no image on screen ( he cannot boot bios or something). If I let it about 1 hour to "cool down", it starts with that lag. I tried to replace RAM, HDD, nothing.
I had windows 7 x64 but now I formatted all and got windows 8.1 pro. What's the problem? I really tried everything.
