i built this pc and its been working great for about a year. all brand new parts. anyway, i was out of town and from what i was told my son powered it down from the button my surge protector instead of the power button or windows shutdown. whatever happened, now when i turn it on, i get power but thats all. no bios, windows etc. i dont have spare parts anymore to swap out and troubleshoot it. i have reseated everything and made sure all the connections are tight inside. hooked up a different monitor and tossed in another harddrive from another computer. still nothing. any ideas?
