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. :pt1cable: 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!

EDIT, 3 in a row of the same thing :)

I would first remove and reinstall the memory/video card(including its power connectors.) in case all the process of removing the screw caused them to come just slightly loose.

Normal PC power supplies do not hold power once disconnected. With any luck it is something else and not the power supply.

You probably shook the graphics card out of its socket. Check that it is properly seated (and do the same for any other cards and connectors). This is assuming the screw didn't damage anything when it was bouncing around; I doubt that is the case.

Thank you for the advice. I actually experienced the problem with the monitor running out from the motherboard's DVI output. However, after reading these responses I switched it to run off the graphics card (reseated just in case) and the PC is now working perfectly.

However, the integrated graphics are still not working (they were fine before)... should I be concerned about my motherboard?
