My pc wont boot

[Vegetto]

I had an issue with pc.

Firstly I should mention that my pc isnt new. I have it now for almost 5 yrs. So considering that as you will see leater I was sure that it was PSU that caused problem.

 

PC specs on the beginning :

CPU: intel core i5 650

MOTHERBOARD: gigabyte ga-h55m-d2h

PSU: LC Power LC600H-12 600W

GPU: NVIDIA GEFORCE GTS 450(1GB)

HDD (it is new): 3.5" SATA3 7200 1TB Seagate Barracuda Guardian ST1000DM010, 64MB

RAM: HYPERX 4GB (2gb x 2)

 

Pc would randomly restart, like 10min after it booted up. While restarting it produced beeping sound which constatly beeped until it restarted again and again with same beeping.

First I figured out that one RAM stick isnt working so I used only one stick of 2gb and it worked for a week or so and after that problem came back. I knew that HDD is not problem cuz I bought new one few months ago. After that restarting I would dissassamble pc or just wait for day or so and it would boot and problem will start again and so on.

 

I red online it could be power supply, cuz I didnt have any other PSU I bought new one and two sticks of 4gb RAM.

 

New replaced parts: 

PSU: Raidmax Cobra RX-500AF-B, 80PLUS Bronze/PFC/12cmFan 500W

RAM: Samsung DIMM DDR3 4GB 1600MHz CL11 (2 sticks)

 

I was happy that I finally managed to fix pc, BUT after two weeks or so, at the time I am writing PC is beeping on the boot and wont turn on just restarts by it self with beeping :(, I cant see anything on the screen.

 

Thank you in advance, please help if you have idea what could be the problem. I will try to troubleshot while waiting for your response.

I switched places of RAM sticks (first one in to second slot and second in first slot) and pc booted normally. I am sceptical how long will it work. I am starting to think that my mother board is killing RAM sticks. If so does warranty cover that?
