Exactly as the title state's, for the past 2 months now i have been getting random BSOD's when the computers is on for longer than 5 hours. first is is random crashes, then it recovers, then my monitor shuts off and on, then my keyboard, then my mouse stops responding(But is still receiving power), its like the PC is slowly shutting down part by part. this all happens in the space of 5 minutes, then finally the BSOD happens. It happens either if i leave the PC, or try to shutdown. I've not installed any new hardware in over 2 years and wiped my PC of anything i don't use/need. Iv made a point to not save a thing (not even and image) to my computer in over 2 weeks to see if my relentless saving of images/apps/programs is what is causing it. I have 2 HDD's both with over 300Gb of space left. I'm at a wits end, every solution i have tried fails, is my computer slowly dieing? Literally any help is greatly appreciated as my knowledge on this is limited at best. Not sure if this is Hardware or Software related so apologies if this is in the wrong section.
The rig is an i52500k, GTX560Ti, a Gigabyte Z68 motherboard and its all powered by a 650Gold PSU.

This is the only shot of the BSOD i could get, Any other info needed ask and i'll do my best to provide it.

Also been asked this before but i shut my PC down through Windows, never the buttons on the Case.
 
It may not be your ram. most bsod from ram wont make the pc shut down it hard lock or blue screen on you. if the pc fans are working and the pc not dust bound...try runing hardware monitor or another tool to check your power supply outputs. It may be that there a bad cap in the power supply or a bad voltage reg that when the unit been on and gets warm the part fails in the pc. to rule out ram run memtest86 from a boot disk....if there a failure take 1/2 ram rerun till it clean.
 
That is usually attributed to a failing power supply (not the only possible issue but the most likely). What is the make and model of the PSU and has it been in the system since new (~ 2 years old?)
As a start, you might try running without any unnecessary peripherals attached (pretty much all but monitor, keyboard and mouse) and if you have spare mouse and keyboard you might try those also (simply to eliminate them as a possible culprit here, rarely those failing can cause similar symptoms)

The PSU is a Corsair 650TX Gold, and yes its been in for the past 2 and a half years. I'll try memtest86 aswell but all my temps are normal and never rise over 60C
 
Here's where I would personally start... remove the PSU from the system. Using canned air with an extension tube, work inside the PSU really good until no more dust comes out - get the corners and try to work every angle inside (the plastic tube is non-conductive and should keep the fan from spinning) then with canned air, attack the heatsink(s) over your VRM, blowing under them from as many angles as possible (probably not needed but might as well)
