PC Randomly Reboots

[British_Monarchy]

Hmm that looks nice. I cant see any Reason why the Airflow shouldnt be good enough. Do you have Fans in the top?

No, just the ones that can in the case front and back. CPU untilisation has maxed out at 15% in the last few hours

It is a good idea to get your own PSU tester. They don't cost much and are a quick way to diagnose if the PSU is the problem. If it isn't, great, now you know for sure it isn't the PSU and you can move on. As far as heat goes it isn't a bad idea to remove the cooler and reapply paste. make sure to clean both surfaces with 80 to 90% rubbing alcohol. the stock paste isn't very good I recommend arctic silver. But regardless of how well the cooler is attached if there isn't enough airflow in the case the CPU or some OTHER component my be overheating. Post a pic of your case indicating the direction of the air-flow. On your case you want: Front in, side in, top out, back out. As the PC sits now put your hand behind one of the exhaust fans. If it is really hot or you can barely feel it you probably need more fans.     

Air flow is good, one front one back and the air from the exhaust is not even touching warm

Thats not necessarily a good thing

Ok, close the Case run a Benchmark that stress the PC. Run Coretemp and GPU-Z while you run the Benchmark and check the Temps. If the PC shuts down, go to event manager and make a picture of it. Like that

So cool air coming out the back isn't necessarily good?

hot air not coming out and staying in the case is a bad thing. 

[DarthSlater77]

but your temps may be fine and it is a different issue.

OK, so I have opened event viewer and found the critical events that caused the reboots in the past. The source is "Kernel-Power" and the event ID is "41"

No, the whole point of exhaust in anything to remove a unwanted biproduct be it fumes in a car or heat in a PC. cool air coming out of exhaust can certainly be a sign something is a miss. its not a sure fire way to tell something is wrong but its a potential sign that the hot air is sitting stagnant in the case.

There are other explanations too mind its not a surefire 100% something is wrong but its something to note.

PSU problem.

dont look into this much having just googled it all this means is I shut down and dont know why.

From Microsofts support site

 

"The kernel power event ID 41 error occurs when the computer is shut down, or it restarts unexpectedly. When a computer that is running Windows starts, a check is performed to determine whether the computer was shut down cleanly. If the computer was not shut down cleanly, a Kernel Power Event 41 message is generated. 

An event 41 is used to report that something unexpected happened that prevented Windows from shutting down correctly. There may be insufficient information to explicitly define what happened. '

Would something like firestrike work as a benchmark??

The Kernel ID is useless.

Yes Firestrike will work. Make sure you run Coretemp and GPU-Z. And keep an Eye on the Temps all the time.

The Kernel is the base code that interfaces with the hardware. A "Kernel-Power" issue either means there is to much voltage and it is shutting down to protect itself or there isn't enough to keep the system running. Like when you hold down the power button or unplug (not enough voltage) the PC to hard tun it off, it generates this error in the nanosecond of power remaining in the caps on the board. and yes fire strike is fine anything to push the components to there max.

I downloaded Firestrike to stress the system. Upon booting up my system crashed and has gone into endless reboot cycles with Windows trying to sort it out. The times that I have manged to get it into the log in screen I started to enter my password then it crashed, froze and started the reboot cycles again. I think that this is beyond me and I will take it somewhere to get a professional to look at it.

I would like to help you. But without getting my hands on it, the Help i can offer is very limited. Sry Dude. Good Luck.

Sounds like it is time to attempt a reinstall of windows but first test the PSU. It sounds like it is dead given your prior information.
