Hi,
In an ambition to refresh my gaming PC and hopefully make it quieter I did a rebuild 2 weeks ago. I have run into an issue that I am unable to resolve and are looking for recommendations on how to proceed further. As full background info, I should perhaps mention that the RAM on my old build stopped working "sort of".
Old build:
Lian-Li PC-07 chassis
Corsair AX850 Gold CPU
Asus Sabertooth X58 MB
Core i7 950 CPU running at stock
12GB (3x4GB) Corsair XMS 1600 RAM running @ X.M.P. settings
MSI GTX970 Gaming GPU
Crucial MX-100 512GB SSD
Samsung 1TB 7.2k SATA HDD
Noctua NH-D14 CPU cooler with only the 140mm fan centrally mounted
ASUS ROG SWIFT monitor (2560x1440 GSYNC)
I use the PC for mostly general purpose activities and gaming. Most played titles are not extremely challenging from a graphics perspective: World of Tanks, Fallout 4, World of Warships. During the summer I started experiencing crashes and total freezes especially in World of Tanks, and the failures led to the BIOS falling back to default options (overclocking failed). I tried using "Auto" as default for all settings including memory but this led to powercycling during startup so apparently there was some error reading the SPD of the memory. Using X.M.P everything was normal except for the crashes while gaming. I tried removing and reinstalling the memory but after this Windows only reports 4GB being present whereas BIOS and CPU-Z sees all 3 sticks. I saw this as an excuse to upgrade the PC with the following parts:
New build:
Fractal Design Define R5 with extra 140mm fan
Corsair AX850AX Gold CPU (reuse)
Asus Z170 Pro Gaming ATX MB
Core i5 6600k CPU
32GB (2x16GB) Corsair Vengenace Black LPX DDR4 3200Hz CL16
MSI GTX970 Gaming GPU (reuse)
Crucial MX-100 512GB SSD (reuse)
Samsung 1TB 7.2k SATA HDD (reuse)
Noctua NH-U12 CPU cooler
Same monitor as above
I assembled everything and the PC booted to BIOS normally, I left all settings on auto and proceeded to do a repair of the existing Win 10 install on the SSD. This proceeded normally with the usual 2-3 reboots along the way. I porceeded to reinstall the SW I had lost during the Windows repair, reinstalling Office, restoring backups in outlook etc. Redirected My Documents, Pictures, Music, Movies etc to the D:/ (HDD) drive. The evening was running late so after this I shut down the PC. The next morning it was completely dead, I thought I might have a bad connection somewhere so I unplugged and replugged everything on both PSU and MB side, and the PC started normally, tried shutting down and again no response. Cleared CMOS, removed battery and power for 15 mins, no change. Isolated which cable would need to be unplugged to it being the 24 pin ATX. Disassembled PC and tried breadboarding with the following findings:
With no GPU or storage, touching the pins for the power button causes the PC to boot and MB speaker issues one short beep (everything OK) touching the pins for 3 seconds causes a shutdown. A new short touch of the pins makes the PC boot up again with an OK from the MB speaker. I can repeat this several times with no issue.
Adding the GPU I begin to have some issues PC sometime boots, sometimes not, I can resolve this various ways, changing the PCI-E cables from one connector to another on the PSU worked once, switching which PCI-E cable uses 8 and which uses 6 pins to the GPU works sometimes but not consistently. I have since reassembled the PC but feel I'm still on square one. PC boots once but requires pulling the ATX 24-pin to be able to restart.
Some other observations:
As I have the sidepanels off, i can just barely hear a quiet clicking noise from the PSU when the PC runs.
The fan on the PSU runs after shut down (not sure for how long...), I guess this is normal.
It is impossible to wake the PC from sleep mode, power button blinks but just goes off if I push it, no response to any keyboard input...
If I manage to restart by pulling the ATX plug, the ethernet port fails to be able to wake my Powerline "wall wart" from its powersaving mode.
I have run 1hr of OCCT standard + graphics load test to see if this would show any crashes etc but everything completed normally.
Any and all suggestions on how to proceed from here would be extremely welcome!
