[SOLVED] Have I killed my motherboard?

[benjaminh]

A few days ago I replaced my R3 1300X with an R5 3600 and ended up with two faulty RAM slots (1 and 2 worked but 3 and 4 gave beep codes). I decided to reseat my CPU but in doing so I ended up with a non functional computer. Great!

 

Symptoms include: Power button and shorting the pins does absolutely nothing, no fans spin or lights turn on at all. LEDs on the motherboard which usually turn on with power going from PSU do not. Funnily enough if I plug in a USB device such as a keyboard with any form of LEDs in it they will light up (which makes me believe it is not the PSU at fault).

 

I have tried: Removing RAM (nothing), Removing 24 pin (my keyboard would stop lighting up at this point) and reseating 24 pin (my keyboard lit up once again), Unplugging and plugging back in the kettle plug for AC and turning the PSU on and off to check that I'm not doing this while the PSU is off (nothing).

 

Specs:

Motherboard: PRIME B350 PLUS

CPU: R3 1300X (OLD) / R5 3600 (CURRENT) with stock cooler

Memory: 2x 8GB Corsair Vengeance LPX 3000Mhz

GPU: MSI Gaming X GTX 1060 6GB

Case: S340 Elite

Storage: WD Blue 1TB HDD & Samsung EVO SSD

 

The likely outcome is my motherboard is buggered (I suspect so because of the motherboard LEDs not on when power is supplied) but any help and advice is appreciated, thank you.

ok resetle the 1300x does it work?

I'll try that later, thanks.

well if works with that then a bios update is requiered but still the mobo should power up still though have a look at it as well psu in w??

Did you flash the BIOS prior to the CPU replacement?

Before I replaced my R3 with my R5 I updated to the latest BIOS version and the CPU worked fine but RAM slots 3 and 4 caused beep codes on startup when I upgraded my CPU (it was fine before I upgraded).

as both of them say.

youre MOBO needs a bios update to work with that CPU

Ryzen 5 3600 needs bios version

4801 while your old CPU could run on bios 0406

 

ohh you answered meanwhile,

please check your bios version so see if  it 4801 or newer

[the heck with this]

well is the r3 x64 and the r5 x86?

sort of thing?

to be fair i cant be that technique as i have no revalent experiance with amd the only amd i had was and fx 3000 something with i packed it and store it as  is after couple of months

listen carefully to the beeps count them then look for you motherboard to find out what these beeps mean they alwayas mean something and 99% are the solutios as they point you the direction to look

maybe because of the single - dual rank requirements, check the manual.

clean the sticks before hand, sometimes dusty sticks won't run.

would be lovely if you can spray some electronic contact cleaner to the slots.

Error codes in 3 and 4 would be normal depending on how your motherboard wants it's ram plugged in. Check the manual to be sure

Wtf they both are x86-64. 

[the heck with this]

so basicly both prossecors are 64 bit 

[the heck with this]

cuse the error he gets usually would be by a 32 bit processor

as I said in the OP, the system does nothing when I press the power button or short the pins on the motherboard for power. Beep codes would be a miracle.

That was a previous issue, now my system doesn’t turn on at all.

lol?

with the igpu have you tried?

Desktop cpu's are 64bit since 2004.

And yes, lol. OP's cpu's dont have igpu.

Check the CPU, are there any bent pins? Have you tried booting with only one RAM module in place (try both modules individually). Check all cables, is the CPU power (8 pin cable) connected? If you put in your old CPU, does the system post?

this is solid advice.

Yesterday i had a similar issue with a system.

Had to reseat the ram several times, and had to clean the cpu socket with air "opening" and "closing" the retention lever to clean the socket. 

Good luck

Earlier when I read this I was simply going to reply with how there could possibly be no bent CPU pins but when I took my CPU out of its socket for an inspection I saw one bent pin. When I put in my old 1300X and turned PSU switch on, the motherboard light lit up. When I then fixed my 3600 and put it in, it too made the LEDs light up and the system perfectly POSTed as well as my previous memory issue resolved.

 

This is odd as I took the 3600 out a few days ago to check for bent pins to try and fix the memory issue so either I bent them after that by putting it in the socket or I didn't have a close enough eye.

 

TL;DR: I fixed my system and the issue was merely a bent CPU pin.

Thank you everybody for your support.

Glad you were able to solve the problem.
