Good day


Update the bios to the latest bios version. Also play around with your sata mode from ahci to ide and vice versa and there should be one that will stabalise the machine. Make sure the windows updates are up to date. As for the graphics, i would recommend that you download the lates graphics card drivers from the vendors website and not acers website. The USB 3.0 driver is also available on the acer website: http://support.acer.com/us/en/product/default.aspx?tab=1&modelId=4280
