Helo people i hav acer 5230 extensa with window 7 built pro.The problem is system and video bios are shadowed.I think this faulty is caused by a local technician wantin my money,its as if i dnt have a laptop anymore and im stuck cos i dont know what to do

Did you install or uninstall some software or drivers or maybe driver updates???
Can you boot in Safe Mode???
For how long you have this laptop???
Could you tell us what temperatures you see in BIOS???
Hope this will help you mate...
Report back please...
