Random shutdowns after 30m-1h 30m

[bottlez14]

I Just bought a new motherboard and cpu and now my computer is randomly turning off after 30m-1h 30m. I dont smell anything out of the box so i dont think its psu overheat (it also dosent feel hot). My audio on my motherboard also isnt working if that might be connected (grounding issue maybe?)? On top of all that my HP case dosent have a power switch that supports the motherboard so im jumping it with a skrewdriver if thats the issue? (just ordered a new case.). Anyways if anyone has any suggestions on what it might be throw it out there.

What PSU do you have? If it came with the HP case it might be junk.

WHOAAA! Your case doesn't support the power connector on the MB and you are jumpering it with a screwdriver??? I'd settle that problem right after you look at the PSU and tell us what it says on the label. Manufacturer, model no., voltages.
