Hello I have an Acer Aspire V3-571G-53216G50Makk. As some program I use usually are not 100% compatible with Windows 8, I tried to format and put windows 7. When I installed windows 7, the computer started to heat up and shut down too ... I was convinced that the problem was the BIOS. So I updated it from v2.04 to version 2.13. I did not notice any difference and the computer continues to shut down. I had only to open a game for 30min. I went back to change the BIOS to UEFI type and installed again windows 8. With windows 8 computer already accelerates the fan and he does not turn off so many times. As the UEFI BIOS type is recommended for windows 8, that have logic ... However I still find that the computer does not work well. If I play something for 1hour, some times the computer shuts off and sometimes not. The computer shuts down and after 2-3 seconds, it automatically turns on. I think this is very strange ... The fan speeds up a little, but she never arrives at full speed! So I thought it was a problem in the version of BIOS and I have tried all the ways to replace the original version, v2.04. Unfortunately, without success! I no longer know what to do ... You are my hope, given the vast experience you have. Actual BIOS version - 2.13: h**p://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_2.13_A_A.zip?acerid=634950419479639493&Step1=Notebook,%20Ultrabook&Step2=Aspire&Step3=Aspire%20V3-571G&OS=8cn1&LC=pt&BC=Acer&SC=EMEA_21 Original BIOS version - 2.04: h**p://global-download.acer.com/GDFiles/BIOS/BIOS/BIOS_Acer_2.04_A_A.zip?acerid=634846811372439768&Step1=Notebook,%20Ultrabook&Step2=Aspire&Step3=Aspire%20V3-571G&OS=8cn1&LC=pt&BC=Acer&SC=EMEA_21 RMN: Q5MV1 Please help me!
