CPU problem

[SUPERDALEJR88]

This is my first post so I'm not quite sure if I'll get any help here.

Basically about a week ago my computer started shutting off randomly after about a 1/2 hour of use. I started it up again but monitored the temps and all of my cores according to thermals on the CPU were fine (about 40 degrees C) and so were the packages, but on two of the 4 "temperature #x" (according to my mother board thermals) were bouncing between 80 and 100. So on my CPU the temp was fine but the motherboard the temp was high. The problem persisted even on idle or in the BIOS, so I bought a new AIO liquid cooler. I unplugged and re plugged everything back in internally and moved it to a better ventilated area. It ran for about an hour without a problem, then started happening again. I cleaned off the thermal paste and tried again but still had the same results. I've read that it can either be a defective power supply or a defective CPU, but I'm lost as to which it could be and I don't want to spend $400 to replace both. If you guys need system specs, I can provide that or anything else you may need. Thank you

specs and a screenshot or two would help...

over clocked?  if so, remove all overclock settings, clear CMOS. unplug GFX card, unplug extra HDD.  you might also like to remove all but one RAM modules. Boot the box and see what happens.  

 

can u attach a screen shot of the results as well?

Running at a stock 4 GHz currently, I also disabled hyperthreading and lowered it to 2 cores to see if that would work and it didn't. I'll try everything else when I get home tonight

Shut off after about 10 minutes. It shuts off and then instantly turns back on but doesn't post, chassis fans don't spin, error code just says 00 which isn't anything

Don't have permissions to see ur screenshot for some reason.

 

Interesting problem.

 

I don't think it's the CPU because if it were it wouldn't turn on in the first place.   

 

Does the PSU get hot? does it give off a funky smell?

 

I would get a new PSU - since that's the cheapest of components to replace.  But it could be the motherboard, which would suck....
