Boot not working

[JoelGurken]

Hi, I have the problem that my pc (new from april 24) was booting perfectly till, like four weeks ago. At that time I installed more games on my pc so my 2TB Ssd has now like 1,5 Tb used. From there on my pc started to stop booting randomly. Mostly when i turned it on a third time a day. It was strange he just switched to bios. I turned some unuseful settings on and off again and restarted the whole thing. Somerimes it worked immediantly sometimes on the third try… now today it fully flipped me out i couldn‘t get him up to windows again and resetted the bios multiple times. I recognized that my ssd didn‘t got found (the yellow led was on from the motherboard and in the bios the „storage information“ tab was empty“. I reinstalled the ssd and suddenly on the next boot it worked. At the evening I retried booting him (1h ago) he didn‘t boot again. I reinstalled the ssd and nothing vhanged, the led is on. I personally think its something because my ssd is too big for the bios to use it right or whatever. Can somebody give me a clue or does somebody had something like that before? I really want to change the mainboard to check if it is the problem because the ssd isnt. So i think about buying the z790 aorus elite or a bigger atx asus rog to check if this will work. But fr its a lot of money for me and much more work to build the whole thing for anorher time.

I feel suspicious about your PSU. In theory, 750W should just about be enough, but your machine could be close to that limit under load. It might be worth trying a higher power rated PSU if you can borrow one to test? Otherwise, also worth carefully checking all of your cables to/from the motherboard and PSU. Make sure both 8 pin CPU cables are connected as well. 

Finally check your SSD partition type. GPT is nearly always the best option for Windows. It's unlikely that you have an MBR partition type, but that is limited to 2TB, the size of your SSD. Worth checking.

Ok, thanks for the quick response i try those things and give some feedback in a few days

Okay I tested it and it didn‘t change a thing. So I built my m.2 druve on the second connector of my Mb and it didn‘t change too. Now I got myself a Laptop from a homie to build the Drive in it. The drive worked flawless. Should I buy myself a new Mb and sell the other as an old used where the M.2 aren‘t working, but my 4 SATA‘s are working? Or should i let someone repair it…

Maybe it is a faulty motherboard then - it seems that it should still be under warranty, so best to contact Asus and see if you can get it changed. That's my suggestion, good luck.

Ok I will do that, it should be under warranty till 2026 or so. Thank you very much
