My friend asked for me to fix his computer because nobody was booting, so i saw that the problem was that the HDD was loose so i fixed it, it started to boot and i ran system recovery, and during that laptop discharged because i forgot to plug it in, so i plugged it in and turned it on, and it shows windows 7 logo loading for 5 seconds and after that immediatly blue screen of death appears and it restarts again, and it loops like that over and over, also i cant access my BIOS for whatever reason, i try to click f12 as fast as possible but nothing, please help!!!!
