I was taking my graphics card out to clean and it got halfway stuck in the PCI-E slot, so I pushed down on the plastic retention clip with a flathead screwdriver and basically applied a bit too much pressure and it snapped. Ok (so I thought) no big deal as I figured as long as the graphics card is securely screwed in it should be ok without it. However when I'd cleaned the GPU and reinserted it my PC will not boot at all. It's a new motherboard and I've only had it a few weeks and its been fine up until now. I can see the lights on the board are on, so I'm not sure if I've broke it, is there any way to know for sure without an RMA? I've tested another GPU and no joy.
Would a PC repair shop handle this sort of thing or is more of a specialist job? I don't really know anyone personally unfortunately...
