Display Signal Stops, Computer Runs, Must Cycle PSU

Recommended Posts

Posted · Original PosterOP

I've had this intermittent problem where my PC will stop sending a display signal to my monitors (monitors are powered and display NO SIGNAL), but the computer fans and lights continue to run normally. The power LEDs remain on, yet holding the power button won't turn the machine off. I need to go to the PSU, shut it off there, turn it back on, then hit the case's power button.

 

I've run stress tests on my PC (Intel Burn Test) and monitored the temps, and the Tdie never go above 70oC (as measured by HWINFO).

 

My feeling is that the PSU is to blame. I fear that it might be a little too close to the power draw, and my unit is a bit of a bargain bin choice to begin with (EVGA 750 BQ).

 

I've had this problem with two separate GPUs, so I feel safe ruling that out.

 

My question to the wise folk of the forum: Do these symptoms sound like a PSU problem to you as well? What wattage PSU do you think I should go for? 1000W? 1200W? I'd like to upgrade my RX 480 to something like a RTX 2070 or a second 2080 sometime soon. I'm thinking of the SuperNOVA P2 series, but rather not spend the cash if you all think e.g. an 800W will do.

 

My build:

CPU: AMD Ryzen Threadripper 1950X @ 3.4GHz

MoBo: MSI X399 GAMING PRO CARBON AC (MS-7B09)

PSU: EVGA 750W BQ

RAM: 32Gb DDR4

GPU (Display): RX 480

GPU (Secondary, Compute): RTX 2080

Monitor 1: DELL U2412M

Monitor 2: ASUS MG28U

Drives: Seagate ST2000DM006-2DM164, Crucial_CT1050MX300SSD1, PM961 NVMe SAMSUNG 256GB, ST8000VN0002-1Z8112, ST8000VN0002-1Z8112

 

Power Estimates:

PC PartPicker has these wattage estimates for me:

 

A total of 729W (I didn't include my drives).

 

AMD Threadripper 1950X 3.4 GHz 16-Core Processor 22W - 180W
Noctua NH-U14S TR4-SP3 82.52 CFM CPU Cooler 5W - 10W
MSI X399 GAMING PRO CARBON AC (MS-7B09) 17W - 70W
Corsair Vengeance 32 GB (2 x 16 GB) DDR4 Memory 29W
Sapphire Radeon RX 480 8 GB NITRO+ OC Video Card
MSI Duke RTX 2080
56W - 225W
53W - 215W

I experienced this problem with one GPU, but it happened far less often.

Very interesting. When you say it's RAM related, you mean that the RAM is corrupted? How do I go about testing this? Would the regular "memory checks" work just as well?
