Anyone looking for a problem to solve? I have an issue I’ve never come across. It appears my PCIe bus is losing power/shutting down? Or something.
Monitor loses signal from GPU. Mouse & keyboard lose power (plugged into USB 3.0 plugs on back mobo I/O panel.) Sound cuts out (plugged into back I/O panel.) NIC stops sending & receiving (plugged into PCIe 3.0x4 slot.) Computer keeps chugging along. GPU is still lit up by it’s LEDs & fan spins. CPU cooler still runs.
Only way I have found to recover is to hold the power button until shutdown. restart button does not work (outside of this issue, it functions correctly.)
AMD R7 1700. Stock clocks
Asrock AB350M Pro 4
Corsair LPX DDR4 @2133 MHz 2x8 sticks
EVGA GTX1070 SC2. Power & Temp sliders maxed out in EVGA PrecisionX, but no manual overclock or overvolt.
Corsair AX860i PSU.
Samsung 960 EVO (PCIe m.2) & 860 EVO (SATA m.2)
Chinese 10Gb NIC (x550-T2)
Windows 10 Pro
When does it occur:
Normal use for me. BOINC is running on 8/16 cores. Additionally I’m either derping in SC2 or folding at home is running on the 1070 or I’m watching Twitch/youtube. CPU package temp is ~50C. GPU temps are just shy of 70C max. All other mobo temps are sub 40C. Problem does not always occur at peak load (sometimes it’s just BOINC running when it cuts).
What I’ve tried:
I’ve memtest86’d both ram sticks together, and each separately. No errors after 1 pass each individually & 4 passes together (overnight). Have re-seated the ram several times.
Checked GPU for proper seating in mobo & power cables for proper seating.
Problem has repeated regardless of which DP socket I plug into on the back of the GPU.
(insert joke about turning it off and back on again)
Corsair Link shows the following stable values:
With BOINC & Folding & a game running it shows the following current values:
Anyone know why it’s reading 0A on the 24-pin? Could my computer even function with 0A on the 24-pin?
Would love some troubleshooting help if anyone’s bored and looking for a problem to solve. Will probably try loading optimized defaults in UEFI and double checking all connectors on back of PSU next. After that will be BIOS updates to latest. Any other suggestions welcomed!
