3 year old ASrock Extreme 4 Z170 suddenly not boot

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi All,
I have a PC which I have had for 3 years and it has been working fine until last week when it just stopped. On pressing the power button the PC powers ON but immediately stops, the display on the motherboard showing a zero before it turned OFF. I have removed the graphics card which made no difference. I then removed the two sticks of RAM and restarted the PC. This time it starts and gets to code 53 and stays ON. Searching Google shows that it requires RAM to be installed which is understandable. Next I inserted one of the RAM sticks in all the slots one at a time. They all give the same code of 19 before turning off. Now if I put two sticks into the appropriate slots then I get back to the PC turning on and then immediately turning off. So I thought it may be a RAM issue but I am not an expert so just want to confirm if it is ram before I go out and buy something. Anyone able to help, please.

Specs
Motherboard: ASRock Z170 Extreme4
CPU: i7 6700k
RAM: 16GB DDR4 Corsair Vengeance LPX 3000MHz
Graphics Card: 1080 Founder Edition

	Pull the CPU, clean the contacts on it with a q-tip and some isopropyl alcohol and reinstall it. The 00 code means CPU installation/no CPU error. Also check for any bent pins in the socket. You may also want to test the system with a different PSU, more often than not when issues pop up after a prolonged period of stable use it is the PSU dying.

	I don't understand the reasoning for cleaning the CPU. It hasn't been touch. You mention 00 but it was only 0 and I would expect 0 to be the first number to appear. I don't think this is an error. I will have to open the PC up and rebuild just to be safe but I really don't see there being dirt which suddenly made the computer stop working.

	Corrosion can form on any bare contact in your system, particularly where humidity comes into play.
