    Hi,
    You could try removing the HDD/SSD and boot, if that doesn't help, you can also try removing the CMOS battery, leave it out for 5-10mins before reinserting but you need to do a complete disassembly to access CMOS battery. 
    Please read the last two posts in this thread:https://community.acer.com/en/discussion/comment/487705#Comment_487705

    Thank you for answering my question, by the way is there another method for fixing that problem or software that can help? I'm not expert on disassembling laptop.

    I tried to install windows 7 but error appear when getting files ready progress , it say No device drivers were found. Make sure that the installation media contains the correct drivers, and then click OK.

    I don't think there's any software solution but you could at least try removing the HDD. The video in the link may help you.

  • As colleague @ brummyfan2 said, remove the hd and driver! However I recommend you remove the rtc battery for a few minutes too!

    Getting to the HDD is not easy.  Go to a quiet place without distractions & proceed slowly.  An old credit card is helpful in popping the tabs.  In the video above, the removal of the HDD occurs at 4:34.  In the video below, it's found at 6:28.  It has a running commentary.

    It's a nice sense of accomplishment when you return from terra incognita unscathed. 
    Unlike using a hammer, which is a force multiplier; use little tools from the home, as shown in the above video, as force dividers.  Our fingers don't fit in the tiny spaces & too much force is generated with them.
