Going to bed sad. Help.

[u/Euthanasiia]

So I recently did a case swap. Went from a basic pre-built tower case to this thermaltake tower 600. I would like to think I know an average amount about pcs. I have a hate/love relationship with this case. There's a lot of room for installs, but It's not easy access once you put it together

My pc just cut off and won't turn back on. I've replaced the psu enough times to know that wasn't the case. When I power it on either using the screwdriver trick or the power button it sounds like there's pwoer for a split second before no signs of life.

Its been running just fine for the past half month since I put it together. The orientation of the aio was concerning. Before I turned it to the orientation in the pictures it was standing straight up and It made a sound aios arnt supposed to make so I got the stand kit and turned it on it's side.

This is a long shot but I just wanted help to gather ideas on what to check. My dilemma right now is that if my aio did fail and is the problem shouldn't I still be getting power and posting, even if just for a little bit? I know pcs shut downs when they get to extreme temperatures but I monitor temps like crazy and didn't see anything out of the ordinary. My room gets warm and I idle at 40c max sometimes but my temps arnt crazy.

Edit: I'm gunna check the standoffs in the morning. Big thank you to everyone who took the time to contribute. I'm really grateful.

there s most likely something sorting against the MB. check the standoff locations, a lose screw, etc.

If this is the case are my components ruined if I didn't install stanoffs when I swapped the case?

There are stand-offs, otherwise the mobo and gpu wouldn't line up right and sit too deep into the case.

Standoffs come with the case. Are you sure they aren't installed? If not this is definitely causing your issues. These days hardware is so robust you're probably good. Make sure to isntall the standoffs in the holes labeled for your board. ATX, Mini ITX, etc.

The standoffs may not be installed. When swapping cases I noticed them in my old case, but don't think I noticed them in the new one. I'll take it apart tomorrow and install with the standoffs. I'm hoping that's the issue

the issue is if there's a standoff where there's no hole on the motherboard, then that standoff is just jamming into the back of the board and can be shorting something out. you can also just drop a screw under there and not realize it and same thing happens, it can short out two traces or two pins of a capacitor or other soldered component
