Easy mistake - Easy fix

I spent 30 minutes trying to figure out why my ASUS Z790 Apex wouldn't post. After doing everything but checking the wires, I finally saw the problem. The GPU power wasn't connected....

Just a reminder for troubleshooting 101. Check the cables before anything else.

Strange, it took you 30 minutes to discover this. Don't take this this wrong way, but I will never call you up at a point of crisis.

Anyone including you could've done this and taken longer. Don't be rude.

we all done similar mistakes. Guaranteed you done massive ones yourself that is rather basic.

Another really fun one is the power switch on your PSU.

I had many a stomach turn around on me after coming back from a long absence to my PC, forgetting I hit that switch before I left
Also my daughter likes to flip the switch on my power block under the desk... left me wondering more than once too

Funny thing about the switch.

The PS3 has one on the back of it. My buddy didn't use his PS3 for something like 9 years because he said it didn't work. So he brought it into work one day as another friend of mine did hardware mods and said he could fix it. Both were perplexed why it didn't turn on until I flipped that switch.

Big brain moment for sure.

It's not being rude. It's the "length of the time" to discover a cable not being plugged in. Yes I have many times discovered I missed cables, but half an hour. I normally discover this under 1 mins. If I discover a problem without taking everything apart again because I really hate dismantling things again, I do a voltage check with a meter by probing the pins.

Besides this good observation or a small tug/pull on the cable is another way to discover it's not plugged in.

Been there done that matey.

Takes me an hour n a half to watch 60 minutes : )

i must admit that's a tricky one, i've done it many times, sometimes we cannot see the wood for the trees. i have to sit back and roll a fat one until the penny drops .

 

[c2DDragon]

I had the 24pin ATX power not fully plugged and sometimes the GPU ones not fully plugged too.
It's always scary when you wonder what you broke.
Now my fingers remember for at least 2 days when I build a computer

Correct me if I’m wrong but wouldn’t the pc still boot in this case if the cables aren’t connected in windows it would lead to instability or possibly crashes but I thought it would still boot up with powered fed from pcie slot

Nope. Not powering on is a failsafe. No one wants a GPU that pulls 200w+ trying to boot on a PCI slot 75w. You're welcome to try with your 3090 though.

 

[Sithaer]

Done something similar in the past more than once.
Like I took my PC down to our garage to clean it with an air compressor and when I wanted to start it up later it wasn't displaying anything on my monitor and was starting to think that I've foqed up something.. 'even tho I'm very careful with that'
Few mins later I've realized that damn man the HDMI cable is not even connected to my GPU.

Not entirely your fault, I'd say. Insufficient power to the GPU usually lets you post. It just fails to enter the higher power states (e.g. gaming) properly.

Doesn't the Apex have Q-Code? Shouldn't it point to the GPU?

Back in the day, in Core2 era, it was a surprisingly common mistake to forget plugging the 12V power connector to a motherboard. Most of the "system not POSTing" threads on many forums had a simple solution

I think that having too much experience with computers will result in simple mistakes like these, whereas a novice would most likely check everything twice just to make sure that everything is connected.

Lol. I had random instability for no apparent reason and found out that my 24-pin wasn't properly seated into the PSU (modular) - it was plugged in but just not quite far enough.

Yeah, it's a clip-in connector, but it's not like you can run around it making sure it's fastened. Many times the clip is facing the PSU or some VRM heatsink, with barely any clearance. Been there, done that.

Luckily anything didn't fry due that (like Nvidia power connectors if they're not plugged properly).

My first PC build with an i7 940 (first gen core about 2009).
Installed the CPU the wrong way round!! It didn't post!!
Beat that for idiotic.

P.S. Amazingly, after finding my error and punching myself in the face, it worked. Luckily I had also attached the air cooler wrongly too.

I also forgot to connect the fan when cleaning laptops, and sometimes forget to switch on PSU power button. Then I have no clue, why laptop is turning off (but so pleasantly dead silent lol) or brand new PC doesn't start.

True. I am very sensitive about my post above (#20). I have never mentioned this to anyone, really.
Finally after all these years, I've come clean. It's a weight off my shoulders.

Worst is ITX builds where the PSU is jammed in somewhere strange and there's an extension to the back of the case, so you don't have easy access to the switch and may not even be able to see it.

I had a mass of wires that would press on the switch enough to put it kind of in the middle when the PSU was mounted, but because it never went past the halfway point would go back to "on" when you took it out to check. That took a while to figure out...

I killed a brand new X1950XTX it was the first card I ever owned that required supplemental power and just board power and powering the system on killed it. Took 4 months to RMA

That shouldn't have happened, though. Even the earliest cards that required additional power would either beep and not POST. Sounds like you got a lemon.
