Mystery crash reboot problem

Hi - it's been a long time since my last post.

I'm trying to diagnose a Windows 10 crash reboot issue on a system I built about 4.5 years ago with a couple of upgrades along the way. This is my third home built system so I have a little experience (just enough to be dangerous!). This used to be a gaming computer but now I'm busy with other things and now it is used as a home office computer. Specs are below. It started about 2 months ago and crashes can be as often as 5 minutes to a couple days and I've tested everything I can think of but I must be missing something. The crashes usually - but always - happen when the system is idle.

I've tried booting to Ubuntu from a USB and everything seems OK for days so that may be pointing to a weird HDD or Windows 10 issue.

I'd appreciate any pointers the community may have.

Hardware Diagnostic Steps

  • Mobo passes hardware test (Pc Motherboard USB & PCI Analyser Diagnostic Card Tester)
    PSU passes hardware test (Insten 20 / 24-pin Power Supply Tester for ATX / SATA / HDD, Black)
    Intel Burn In Test passed
    Furmark Graphics Test passed
    memtest 86 test passed
    Hard drives smart status show all OK
    Disk Checked (Windows 10) each drive - no issues
    Samsung Magician used to check SSD - no issues
    Data Lifeguard used to check WD drive - no issues

OS / Software Diagnostic Steps

  • Windows 10 Home Premium with all updates done (initially I thought the crashes were related to a failing Sep Windows Update but I finally got past that in Oct)
    Ran sfc /scannow - no issues
    Norton 360 up to date and no viruses
    MalwareBytes up to date and no malware

Solution
If it's bluescreening, upload the small dmp files to onedrive or some sharing site. Then post the link

If there is no BSOD it maybe the PSU - It's faulty

@Paul - thanks - there is no bluescreen - it's like someone cut the power (it happened while writing this message) and then upon trying to reboot it often fails (like last night again) and I come home to the blue recovery screen (Troubleshoot or Restart).

The PSU passes the voltage tests but I suppose there could be something wrong. If no one has any other ideas I can try either returning the current one to EVGA (10 year warranty) or just buying a new one.

Anyone have any experience with EVGA's PSU warranty? The PSU is actually only 14 months old - it was a replacement for an older one that definitely went bad.

I used a calculator (results pasted below) to estimate the PSU size if I bought a new one and since it is mostly used as an office computer and the newer video card is a much lower power draw than the previous (and slower) one the size suggested is now much smaller, i.e. 400W not 650W. I could get a 400W one for not much more than shipping the current one back to EVGA. I'll do this soon and test it out and let you know if it worked.

Putting a new PSU in solved the problem. I got a Corsair CX550M at $38 after rebate which was cheaper than the lower powered PSU's I was considering. EVGA SuperNOVA 650 P2 80+ PLATINUM has been RMA'd.
