PC Doesn't turn on

[AwkwardSLCE]

Hey guys, I'm having some troubles here, I tried to upgrade my PC from an i7 6800k to a i9 10900x, but it didn't boot. After a while it seemed to be that the issue was with the RAM being below the one accepted by the CPU. The thing is that I put my old PC back together and now, even if the On button on the Mobo is lights green (MSI X99 SLI PLUS), when I push the start button, both on the case and MOBO nothing happens. Maybe I'm missing something here

How many cpu power cables do you have in the motherboard, some power intensive CPUs need two. An 8pin and a 4pin

8-pin, the thing is that it was working fine like 2 hours ago, even with the new CPU it started, it just did post

Woah, you mean an actual 10900x correct? If so it uses a completely different socket (lga-2066) than your x99 motherboard (lga-2011 v3). You better take it out and verify that you didn't damage your motherboard or possibly the CPU. They even have different alignment cutouts for the CPU.

 

With it not posting after replacing the original CPU back, you have have bent pins in the socket. You very well may have shorted something as well, and inadvertently fried either the CPU or motherboard, possibly both.

No, sorry I didn't specify. I change the CPU and the Motherboard. But kept everything else

Ah, ok then. What was the motherboard that you paired with the 10900x?

[AwkwardSLCE]

An Asus x299. But the PC turned on just fine, it was when I put back what had when it didnt started anymore

It isn't posting at all? Are you able to give me the exact model of motherboard you have. It could give me more to look at to help you.

The on my PC right now, the one I've always had, is the MSI X99 SLI Plus, paired with my cpu i7 6800k, it was working fine 2 hours ago. I try to change it for an i9 10900x and a Mobo Asus ROG x299-E Gaming, and it didn't post. Apparently its because the RAM higher than 3000 mhz, right now I have 2400. So I put back my old PC (the x99) and now it doesnt turn on

Okay so you put the 3000 MT/s ram in the x299 and it didn't post. Did it power up at all but not post? You might try using your 2400 ram in your x299 system and see if it will post with that. As long as everything has power connected correctly and has ram installed it ought to at least be able to enter the BIOS. (Side note: you also need to make sure you have some kind of video out (GPU/VGA adapter or whatever nomenclature you want to use) during boot)

Something else I forgot to think of, depending on when your motherboard was manufactured it may not have a new enough BIOS on it ( version 2002 for your board) to support the 10900x out of the box.
