I'm guessing it's the RAM

That doesn't sound like RAM to me. You usually don't get random reboots from dying RAM. Either the computer won't boot at all or you'll have intermittent issues and stuttering in the OS. And in any case RAM that's in bad enough shape to cause this many issues would almost definitely give you errors in the first pass.

 

It could be a dying power supply. I would find some way to get a tester power supply and run off of that for a while and see if it keeps happening. If not, great! You know what the issue is and can replace the power supply. If it is still happening then you'll have to do some more troubleshooting. Usually hardware issues involving the cpu, ram, or hard drives will result in a BSOD, so it could be a software issue.

 

I have seen corrupt drivers cause random reboots and other funky things. Make sure all your drivers are up to date and see if it keeps happening.

 

Did you install any new software around the time this started to happen? Maybe uninstall it and see what happens. 

 

Can you use system restore to jump back to a point where you know this wasn't happening? That will tell you if it's hardware or not. If you restore back and it keeps happening anyway. 

 

You could actually very well be getting a BSOD and it's just going by so fast you don't see it. Here's what you do to check. Right Click on This PC>Properties>Advanced System Settings>Startup and Recovery Settings>Uncheck Atuomatically Restart under System Failure>OK. Now when it reboots, if you ARE getting a BSOD it won't shut down until you physically shut it down yourself with the power switch. Then you can record the stop error code (looks like 0x0000001E) and post it here (or just take a photo of the entire BSOD). http://www.eightforums.com/tutorials/51683-system-failure-automatic-restart-enable-disable.html

 

As for memtest, at our shop we like to get as many passes as possible. 1 pass is definitely not sufficient. We usually let our memtests run overnight so we get anywhere from  5-25 passes. I think our record is something like 68 passes. 

 

I would try some of those troubleshooting steps and report back.

OK , so I ran OCCT for PSU testing, it ran for like 9 mins , the CPU went to like 70° but nothing happened , and I doubt that its the PSU falut because its 550 W is more then enough for my specs, and i cleaned my PC monthy with a air compresor...

 

I did disable the automatic restart, and im waiting for a reboot.

 

Also its not likely to be a softwere failure because i did a fresh windows 8.1 instal 1 week ago, and formated the C:\ partition( windows ) and all my diveres are up to date.

 

I do have some memory dumps from my BSOD , but I think that has been solved when i did a sfc.exe/scannow and that other comand wich i can't remember but it re-downloads some windows files ( registrers i think ) and applies them.

 

and while i was writeing this , ih happened  agian, while auto restart disabeled, no effect.

OK so I just cleand my 1 card of RAM with alcohol ( although i used something called " rakija " , its a croatian 40% alc . drink ) , anyhow, i noticed in BIOS that my RAM settings were 1333mhz although the RAM itself is 1600 ... so i changed it to that, and ofc my luck, it crashed / freezed at win logo  so i reset the PC and HOPEing my PC wont crash...

Just because your PSU has enough wattage to handle your components and you keep the PSU clean does not mean it cannot be failing. That's why I said to find a separate tester PSU to put into your system. If you stop experiencing rebooots with a tester PSU you then know your original PSU is bad or going bad. 

 

You can still have corrupt software and drivers on a fresh install. If they don't install correctly or a piece of software you install breaks them they can cause all kind of issues. 

 

Also, sfc scan is great! You may also want to run the dism.exe commands as well (just do option one. Don't worry about using powershell. dism is run through elevated command promt): http://www.eightforums.com/tutorials/26512-dism-fixing-component-store-corruption-windows-8-a.html

 

Ah, dang. Well we know you aren't BSODing (or at least you didn't this time). You might try loading up blue screen view and seeing when the most recent blue screen was: http://www.bleepingcomputer.com/download/bluescreenview/

That's why I said usually :)

 

Also, just causally saying "it might be RAM" isn't very helpful. Give him reasons WHY it might be RAM and give him some troubleshooting steps to do and something to go on. Otherwise OP might not get the answer he needs.
