Greetings. I cannot enter in Windows, because of strange/odd letters in beginning of starting the computer. When I start CPU and put power on, there is "Acer" as usually, but then there is blue background, and odd letters. I cannot choose, because I dont understand.
Previously I tried to make CPU faster, but I did some misstake here. I need to get files from CPU and as poor in computers I dont have code for Windows 8.1.
I have no idea how to start to fix this.
