Will I need a new motherboard / CPU soon?

I'm beginning to suspect that my motherboard is beginning to shows signs of age and possibly wearing down. Recently I've been having issues with random reboots which likely involves the PSU, but I was told that the PSU is OK. I had no reboot issues since restoring an older PSU.

Now sometimes my keyboard will occasionally either shut itself off or not turn on when Windows is booting, which could mean that one of my motherboard's USB ports is going bad. The board has SATA II, PCI-E 2.0, and USB 2.0 ports, which are not up to today's standards. However, I have a USB 3.0 PCI-E card installed and my connected USB 3.0 external hard drive is running at peak performance due to Windows 8.1's native USB 3.0 drivers. Is it necessary to upgrade to a new motherboard and CPU? In that case, I would look into either the i7-4790k (Haswell Refresh), i7-5820k (Haswell-E), or Broadwell. I would prefer to stick with an i7 since I do some music rendering and occasional video editing. I want a CPU which will provide optimal performance for everything, including gaming.

What voltages is your psu putting out. You can get this from tour UEFI or from downloading and running HWInfo - Sensors. If you post the results - usually 3 screenshots on TinyPic or similar - then we can see what's going on better.

Pegatron is a new one on me. You might be right. It may have problems. LGA1150 is much cheaper than LGA2011. If the i7 4790k will keep you happy, then you should go for that.

But part of post it to test the peripherals. My keyboard lights up when the pc posts.

Might depend on how soon you want to make a move, Haswell-E and Broadwell are both down the road. The Haswell refresh K models are available and paired with the new Z97 mobos, will give you a good strong platform and be upgradable to Broadwell in the future. Budget also will play in, could go the 4790K and pair it with a Hero (Z97 great mobo, been playing with mine since the release using a spare 4770K), or if budget is tighter the Asus Z97-A is another great mobo (built one of these last week)

If you have confirmed that the PSU is not the problem and it is your motherboard, go for it. If you want to go i7, I would personally go with the 4790k. Although it's only 4 cores, 6 cores is a little bit of overkill for gaming and music rendering, even light video editing. If you want to put in more money to invest in an LGA 2011 mobo and cpu, go for it as it will be much faster due to the increased number of cores.

TL;DR
i7-5820k is faster with more cores, but more expensive
i7-4790k is cheaper but not as powerful

what's your budget?
Both i7-4790k and 5820k are expensive...
look like you only work on music/video editing / and gaming
you may just need i7-4790 but not k series

It seems now that the motherboard is fine and that I'm experiencing a PSU issue. The older PSU I put in two days ago completely blew out this morning and I had to put the Corsair PSU back in. It may have been a loose power cable connection which was causing the power hiccups earlier. Is that the case? This PSU was tested good for voltage levels. I plugged the power cord in as tightly as I could. Could it just be a loose plug connection?

But anyway, if I were to replace the motherboard, then I would have decided to go with the 4790k. I will hold on to my current one now and see if it still holds up OK. Meanwhile, I will look into getting a better PSU.

In HWINFO Sensors, where do I find the PSU readings?
