[SOLVED] upgraded my pc and it wont turn on ?

[billybopepe]

I recently upgraded my motherboard and cpu and now nothing will turn on?
Tomahawk B450 Max II
Ryzen 5 5600x

I have 24 gb of ram and the PSU (corsair cx650 m) is definitely working as it's powering my gpu (Nvidia 1050Ti)

latest motherboard bios?

https://www.msi.com/Motherboard/B450-TOMAHAWK-MAX-II/support#cpu

use the flash bios button on the back.

Is the power switch on the case wired properly to the new motherboard?

I've updated it now and the motherboard definitely worked then, all the lights were on and psu went through its cycles but the moment I put all the parts in nothing happens

yup, I tripple checked this, since this was an issue that happened to me recently

Here's a scary thought Any bent prongs on the cpu? or maybe it just needs reseating?

Only install 1 stick of memory on the motherboard and place it on slot DIMM_A2

EDIT: You have the supplemental 8 pin power plugged into the mobo, right?

I mean, I just got it out of the box ? is that possible ? and It wouldn't fit if it was the wrong way round, right ? so I think I can rule that out

If you mean the cpu power, then yeah, I used 4+4 connector,

also I tried the ram in dimm_a2 - it still didn't work
EDIT: i used an 8gb corsair vengence rgb pro stick

Does this motherboard have an on/off switch directly mounted to the motherboard?

Unplug your PSU from the wall. Wait 20 seconds. Now depress the power button on your case and hold it down. While you are holding it down plug the PSU back in and see if that does anything.

Im assuming you already pulled the CMOS battery as a troubleshooting method?

I haven't touched the CMOS battery, do I just take it out then put it back in ?

Take it out, press the power button down for 10-20 seconds then put it back in and try to boot.

Ya never know. I've had the same issue and couldn't figure it out. After days of trouble shooting I pulled the cpu and sure enough there were a couple bent prongs. I don't know if I did it installing it or it came like that. Probably the former since I've been known to be a bull in a china closet snappin' stuff together. lol

Just to clarify, I don't have an on/off button for my motherboard
for the CMOS battery, I took it out, press and held my pc case on/off button for 20s, put the CMOS battery back into the motherboard, plugged the psu into the mains then tried turning on the pc and still didn't work (i still only have 1 ram stick in still)

I'll check this out, it's honestly something i hope isn't the case :')

Then it's probably a bad motherboard.

for anyone else who had this issue I found the solution, I updated the bios from the msi website (from the bios tab not the compatibility tab, to which was my first mistake) - then I had mad an incorrect fan connection so the motherboard would allow my pc to boot.

Thanks for everyones help !!
