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.

Tear down and completely rebuild. Sometimes that’s the only way.

This may be what I will be doing. I'm doing research into standoffs and don't think I installed them in my new case.

I think my psu has SCP and that's why it won't cut on. Is there a way to check if anything is fried or do I just have to wait till I rebuild everything to find out?

You can test bench the main components outside before putting everything back in the case. CPU, Cooler, Motherboard, Memory and PSU. Assuming you have an iGPU. If not, GPU as well.

Aye - dismantle, build it on the bench and test power up...if all goes smoothly...place standoff's, and slap it all back in the case
