EDIT: marking this as solved since my PC is running perfectly using external graphics 48 hours later. Still not sure why the integrated graphics stopped working in the first place but I am considering the problem solved until something else goes wrong with the motherboard.
Also, I re-mounted the PSU with the fan pointing downward, so I can't drop anything in there again.
Thanks all for the help!

I opened up my (hackintosh) PC to install a couple additional SSD's, accidentally dropped a screw into the PSU. Thankfully everything was powered down and unplugged at the time. I turned it upside down, shook it all around, got the screw where I could see it and finally reached in with a needle-nose plier and pulled it out.
Now, however, my PC is acting all screwy. It powers up with the normal beeps BUT I don't see the usual Gigabyte boot screen. Once it starts up, I can sort of see my desktop and cursor, but the display looks all screwy, with large black patches and fields of digital static/noise over the various windows.
So my question is: does anybody have any idea what I might have done? Did I fry my motherboard? Do I need a new PSU?
And what should my next steps be in trying to troubleshoot and diagnose the problem?
Thanks in advance for any help!
