Ok so i somehow locked myself out of bios supervisor and user whilst trying to remove my bios password, i tried all (cmos jump, cmos battery) . i then tried to change the bios by crisis flash ( put VAG70x64.fd in a flash and press fn+esc then power on the laptop). Now when i turn it on i just get a black screen , running fan but thats it. So the internet seems to think its a bricked bios that caused it, any solutions? Will buying a new bios chip fix my problem (blank/black screen and password). Please help, laptop is acer aspire v3-771g
