Hello there, I'm having some issues figuring out what exactly to troubleshoot with my PC. When I try to turn it on, it gives two amber blinks (pauses, blinks twice again, but I'm assuming this is considered just two amber blinks). 
an empty cup had landed on the pc before it crashed, so I'm wondering if this means the motherboard or something in specific was knocked loose? But I'm hoping there's an at-home fix.
Please help! Thank you.
