Hi, I have a homebuilt AMD FX 6300 & EVGA GTX 560 build, and it recently stopped even turning on. This happened a few days after hearing a faint whistling sound from the motherboard, but no capacitors have seemed to be blown. It has a MSI 970A-G46 motherboard from october of 2012, and a Corsair 650W PSU and liquid cooler from 2010. So far, I have swapped power supplies, clearing CMOS/BIOS, tried running on one memory stick, changed keyboards from USB to PS2, as the board natively supports it, but nothing yet.
I am looking for recommendations on what to do exactly.
Please help and thanks if anyone does.

@icraft - hmm, could be that, but would it prevent the board from even allowing the onboard LEDs from lighting up?
@scout_03 - will do, but from what I remember, it didn't even show any signs of anything snapping, it just refused to turn back on.

I have used an old PSU to try it, but nothing, the PS2 keyboards numlock led lights up, but thats it.
I saw something like some sort of Insulation type material sticking out of the VRM heatsink on the bottom a bit, maybe thats whats causing it? Also about the power stage area, nothing seems blown there. Not even a scent of a blown fuse.

One thing that I didn't mention is that I blew the CPU fan header when installing the board into my crappy case. the case was painted properly, and never really had any major issues installing any of my past builds in the case. After clearing the CMOS, it booted right back up. Didn't think that would bother it any.
 
The MSI motherboards have suffered failures . Earlier models had actual fires in the VRM modules because they had no thermal protection . The G46 is supposed to have fixed that , but if you read the Newegg reviews other people have had similar experiences to yours .
This is now outdated but still useful

Were you overclocking?

The ASUS M5A97 R2.0 is a better choice

Yeah, I saw the reviews, though I thought MSI had better boards. I am a bit iffy with Asus boards, as I had the P5QL/EPU from early 2010 and it kept having issues left and right, so I wasn't sure how much better that was. I was overclocking, but it ran pretty well from 4 GHz to 4.5 Ghz without much issue.

I also had the ASRock 880GM LE FX, and it died the same way as the MSI, so at this point, idk, never had two boards blow consecutively, meanwhile my AMD Athlon II X4 based HP runs just fine, just starting to become slower with age.
 


I would have thought not starting was an issue

ASUS and Gigabyte are the best boards you can buy . Asrock are acceptable

My luck was never this bad, I had an Nvidia Chipset based EVGA board that lasted nearly forever, and even though the Asus had issues, it ran, but offered poor overclocking, maxing out my C2Q 8200 at 2.8 GHz, then again, I was running a budget Intel quad and budget memory, but then again, I have heard others getting to around at least 3.5 GHz with them.
Next time I have the budget to, Ill see about getting a Gigabyte, or going back to Asus.

Might RMA Both, though, I will use the ASRock, its a smaller board and its a better Overclocker, planning to use it in an old Dell Dimension case from 2002, And go Intel i5 for gaming (even though I intensely dislike Intel for their prices and support of the fruit tech company), as I need a new office PC, this HP is getting mighty slow, even with 12 GB of memory, I will have the MSI for backup reasons.
Ah, might go Asus for my Intel build then.
