Is this the Acer loger under which you see an animation (spinning circles) while windows 8 is loading? This is important because otherwise someone might get this confused with the BIOS POST logo.
The reason for the hang can be many different things, and t's very hard to know what. a BSOD might tell you that the problem is in a xxxx.sys driver, but in fact the problem is with your RAM. One thing you should know, when the computer does freeze, is it "waking up" from a sleep/hibernation? Or are you starting your computer after you manually shut it down? These two are different because hibernation just restores your system, but does not load drivers. A cold-boot from shutdown has to reload your drivers.
Everyone has their own favorite tools for diagnosing a computer. I'll give you mine.
1) Test your hard drive with HDAT2 (http://www.hdat2.com/) Burn it to a disk, boot from it (you might have to go to your BIOS/EFI settings and disable secure boot, enable legacy boot, or other option to allow booting from CD.
2) Test your memory with memtest86 (http://www.memtest86.com/) Burt it to a disk, same as above.
If you run both tests and your drive and memory are fine, it's likely to be a single driver in your Windows OS that's causing the problems. Instead of hunting down the driver, simply try doing a "Refresh" of Windows. This won't make any noticable changes to your computer (all your files will still be there) but it might solve your problem.
To do a "Refresh" you must load your computer, then find the "Restart" button to restart your computer and click it while holding Left Shift on your keyboard. Hold it until a new menu pops up where you can choose to do a system refresh.
Hope this helps.
