New PC Restart problems

[kenthephoneman]

I recently bought a new PC online from a reputable seller. Everything worked great for several weeks. To the items below I added a WD 2TB Hdd and a NVIDIA Ge Force GT 430 video card with 2gb.

Recently I came downstairs and saw that the screen had not gone to sleep and in fact the whole PC was locked up. Keyboard and mouse wouldn't work it wouldn't reset with the reset button and it wouldn't power off with the power switch. I has to turn it off at the power supply.
Since then it still runs ok but if I shut it down with the Windows power off, it will shut down fine but it will not power back up unless I turn off the psupply, wait and turn it back on and restart the pc.
In a few days I will unplug the HDD and remove the Video card to see if either of these is part of the problem. In the mean time does anyone have any suggestions?
Thanks Ken

Standard assembly and test 3-5 business days" Looks like you accidentally included this. I assume you build and sell these to people?

The old adage is to look at what changes you made BEFORE the problem started. But adding a video card and a hard drive aren't big changes. You could pull the new items out and troubleshoot (properly) or you can just throw everything at it at once without pulling the new stuff.

1. BIOS update???
2. Look at all BIOS settings
3. Video card driver update
4. All driver updates
5. All Windows 10 updates
6. Set power options in control panel (no sleep, turn hard disk off after NEVER)
7. Memory test
8. Boot with a bootable Linux USB and see if the PC will run properly and shut down properly

One of the first things I would do is reset the bios, either by berg pin pull or battery removal.
If you can move the video card to a different slot, try it.
If you are overclocking, bring the settings back to the defaults.
