Riser Card
Please help me! I’m having problems with my computer!?
So every time I restart my computer a black screen pops up saying “921-PCI riser card not installed. Please shut down computer and insert riser card.”
And it stays on this screen until I push F1 to reboot the entire the entire thing!
This started a little while after I accidentally dropped the CPU.
Aside from this, everything else is fine.
But my computer is really really really sloooooooooooooooow now!
Could this be happening from my absent riser card?!
Please please PLEASE help me out!
I know nothing about computers…
How did the riser card go missing?
This has never happened before… 
you need to open the computer and check all of the board make sure they are all plug in

this will show you what you looking for
make sure you UNPLUG the computer frist
your card came out of the slot or broke or the mother board got damage
if it not lose or pop out you may need to bring it to a tech to have them check it
good luck
