System details:
CPU: Intel Core i5 4670K 3.4Ghz (3.8Ghz Turbo) LGA1150 Tray
CPU cooler: Arctic Freezer i30 CO
Board: Gigabyte GA-Z87X-D3H for 1150
Case & PSU: Fractal Design Define R4 + FSP RAIDER 650W
RAM: Crucial 8GB X 2 DDR3 1600Mhz 1.5V CL11 -RAM
GPU: ASUS STRIX GTX970 DC20OC 4GD5
HDD: WD Blue 1TB SATA 6GB/S
SSD: Plextor PX-128M5S Sata3 Marvell+24nm M5
SSD: SAMSUMG 850 EVO 250GB SATA3
Note: I had been overclocking the CPU to 4.2 Ghz since mid 2016.
So it all started a few months ago when I was having on occasions a variety of BSOD which I could handle since they were not so often.
Lately the frequency of this was much higher reaching to a point of having multiple blue screens a day during gaming so I have checked all my drivers and monitored the PC components temperatures where nothing out of order was seen. The issue reached to a peak yesterday as i got "MACHINE CHECK EXCEPTION" while being AFK. knowing the seriousness of this specific stop code related to hardware probably the CPU or MB I have researched and decided to check my hardware.
I visually inspected the PC, all fans were working, all connections were proper and the board seems legit as no boiled capacitors or fault resistors were observed.
I tested afterwards my CPU using "Intel Processor Diagnostic Tool" resulting in a "pass" of each test until "CPU LOAD" test. At this point the PC froze and I had to manually shut down my PC. I retested the CPU resulting in the test FAIL at the "PRIME NUMBER" test module. I tried it several times and each time the process got failed.
I then restored my BIOS settings to default and after resetting my PC could not boot properly to a point that neither keyboard/mouse nor screen did not light up.
Thinking this had to be something related to the Bios reset I did clear the CMOS and removed all hardware but the following: 1 RAM, SSD of OS and basic keyboard/mouse.
After multiple tries I got back into Bios and load my previous Profile changing now only CPU clock speed back to original 3.4Ghz. I then installed my GPU back.
At this point the PC won't boot, it constantly gets itself into a loop of "restarts" where sometimes the keyboard lights up and sometimes the Gigabyte logo shows up but for a real brief moment. Getting into bios is not possible. I tried multiple RAM modules in multiple slots, I tried to replace SATA ports for the OS SSD, I tried a few keyboards in several USB ports and the dedicated keyboard/mouse port.
Is it my CPU who is completely dead or is it something else who might cause this issue? Is there anything one can suggest me to do to resolve the issue?
Any help is appreciated.
Thanks.
