For a couple of weeks now, I've been having an issue where my PC freezes when coming out of sleep. Now I'm also having an issue that when things bump into the desk it is on, my PC restarts. I'm not really sure what to do, although I haven't tried much. My specs are
i5-3570k
AMD Radeon 7950
Asus P8Z77-V LX
8 GB G-Skill Ripjaw
Rosewill 1000 W Bronze Series

Any thoughts or help will be appreciated, thanks

Been here done that, my computer used to sleep fine but since a few weeks, it not working properly.
The only way to fix this is to disable sleep ... too bad

Best solution

ok then youre not having the problem i used to have. Have you checked your power settings? I know it sounds dumb since its not a laptop but sometimes the power setting can get set in a way that certain things shut down when the pc sleep and dont wake back up. This is usually an issue with a LAN card in a laptop but because the settings are in the operating system there may be something that isnt starting that the computer needs to run so it shuts down and reboots instead.

For the bumping and rebooting it sounds like the PSU is detecting some kind of short and is powering off. The reason why I asked about the HDMI was because I had an HDMI cable that had an oddly long connector and it would touch the case and would cause it to short and kill my system forcing a reboot.

I haven't done much with power settings, besides just not letting it sleep. Are there any easy ways to look for shorts besides basically checking every part of my PC?

my way or the right way? lol. I basically start at the outside, the stuff that has the highest chance to be disturbed, and wiggle the cables and such while the pc is on. If the computer crashes you may have found your culprit. Next would be to do the same but inside the case. Especialy check PSU rails that you arent using if it is not modular. One of the pins could be touching something.
