I have an Acer Aspire 6935 with nividia force 9600M GS, I bought it 2 years ago with windows vista, I changed it to windows 7 till last week it was working fine then I thought to reinstall the windows. I changed the Boot priority to USB, it didn't pick up, I changed it again and restarted the the laptop and it got stuck at the main page where the "Acer" is written and "press F2 for Set-up" is written, I cant not do any thing, nothing is working, I do press F2 but it does not work. I have been told that it is Bios Problem and I should flash it, the method was to format the flash drive with FAT and then put the flash drive in having latest bios, press Simultaneously Fn+Esc with power key. I tried it couple of times but it is not working that way. Just wanted to as if there is any other way to fix it.
