PC is dying. Help/advice

[JonHewett95]

So, I've had my PC since mid-late 2013, (specs listed below) in 2015 I moved it from the old case to a new one, after that it had some weird behaviors where after a complete disconnection from the power the power button wouldn't work until I wiggle the kettle lead causing an arc and then it would work fine, very recently my metered electricity ran out at home while my PC was on sleep, ever since I can't go more than 2 hours of normal usage such as browsing or netflix without an extremely low res BSOD error code "WHEA UNCORRECTABLE ERROR" occasionally without warning it will reboot and all the component LED on my motherboard will flash. Kind of sad because it was my first build + upgrade and has pretty high end components (for 2013) so any help/ideas as to what's causing this would be great. If not, can I play current titles with an i3 7300?

 

Specs:

i7 4770K (Running at default after overclock issues)

GTX 780ti

Asus Z87-A

2x 128GB Samsung 840 pro SSD

2TB seagate HDD

Corsair CM 750 PSU

4x 4GB Corsair vengeance RAM

Corsair H100 water cooler 

 

Edit: Forgot to mention that 90% of my steam games have disappeared from my steam library.

Forgot a detail.

the i3 7100 paired with the 780ti actually may not result in that much of a bottleneck, but quick question, did you install standoffs in the new case? because that may be the issue, or the cooler backplate shifted and is interfering with electric stuff

You absolutely can play current titles with an i3 7300 

 

But if you have this extra machine try slowly adding parts from the better one until something stops working.

Yep, installed all the components in the new case meticulously I will check the back-plate though.
