Desktop not working after move

I have a custom built desktop computer I've had for a few years now. It worked just fine up until a few weeks ago, when I moved. Now it resets itself, once, about 5 seconds into the boot process but stays on after that and I'm not getting any signal to my monitor.


Check the cabling is correct and tight - - disconnect and reconnect the monitor cable.
Mine is an issue with the slots themselves, I think. I rearranged the slots my RAM cards were in and it worked after that.
