For a while now the CPU/DRAM would light up whenever I turn my PC on - fans/cooler will come on but no RGB and PC doesn't boot. I changed the RAM and it did the same thing but I tried again (after 2hrs or so) and it came on successfully. Unfortunately the day after the same thing happened where both CPU/DRAM light lit up. I never messed around with my CPU since day 1 (no OC), new ram worked initially so i figured the problem may lie else where so I placed an order for a new mobo (MSI MPG X870E Carbon WIFI). After installing everything the same thing is happening...

My specs:

AMD Ryzen 9 7950x
MSI MPG X870E Carbon WIFI
48GB DDR5 Corsair Dominator Titanium (24GBX2)
RTX 4070 Super
Corsair RM850e 80+ Gold
NZXT Kraken 360 Elite RGB
10x Lian Li TL fans
1TB SN850X SSD

I'm debating whether or not the issue lies with the CPU or even the PSU.
 
red cpu light, yellow dram light. manual says red cpu light = not detected or failed, yellow dram light = not detected or failed
 
Ok ill look to replace the CPU after AMD releases their X3D line of CPUs, rumours point to an end of month release (early november on the shelves). I guess ill be using my macbook in the meantime.. Ill be sure to update the thread once i get my hands on a new cpu.

Anyone else reading this feel free to drop your thoughts on the matter as well.

Also thanks a lot for the quick responses @tamzzy , really appreciate it!

Is this a boxed CPU? According to their website specs, boxed CPUs should have WOF on the end of the part ID.
 
Yeah, I bought it from SCAN UK. There is another P/N that ends in WOZ, upon browsing it seems WOZ is for one without a cooler and WOF is the one with a stock cooler. Not sure if this is entirely correct. I do remember not having a stock cooler provided

On their website they say that you get a 48 hour turnaround if you RMA it, though @tamzzy may have advised you to use AMD direct for a reason.
 
Ok great, I will contact them tomorrow! I only mentioned where I purchased it from to you so thats probably why. Also I'm sure you are already aware but there is some thermal paste residue on the exposed components on the CPU (not sure what they are), was wondering if this would cause any issue with the RMA?

Thermal paste is not normally conductive and if I google what I believe to be the paste that NZXT uses, it says specifically that it is: "non-electrically conductive and non-curing which prevents short-circuiting". But, to avoid problems with the RMA it might be wise to very gently remove it (as you would thermal paste elsewhere), since you don't want to give anyone an excuse to blame you. If you don't own anything appropriate to remove it, then it is best left alone.
 
I used Arctic MX6 thermal paste which seems to be ok, I do have some isopropyl alcohol 99.9% so I just remove as much as I can.

Also do you know how long it usually takes to RMA and receive a replacement?

no particular reason, just assumed it was a self-built boxed component
i've RMAed with AMD a couple of times and it was painless and just required the receipt

if it was a prebuilt then yeah, go back straight to the etailer

I built it myself, just bought the majority of the parts from there. Would it be easier to do it through them or directly with AMD? First time doing this so I'm clueless

the last time i RMAed through AMD was 4 years ago now
it was very painless and if i recall correctly received the replacement part in about a week (or just over)

@Kelt ouch.
personally have had a flawless experience with them
(and it was a refurb part that i bought from the MM, they actually honoured the refurb warranty even though i was a third-party)

Ok sounds good. When filling out the P/N which option should I select? 100-100000514WOF or 100-100000514WOZ? On the CPU itself it says 100-000000514
