Windows 10: PC has bluescreened on average every half hour today.

I've been able to use a few previous windows support articles to narrow down that it is a USB error of some sort. For right now I have 3 minidumps uploaded here, all were from today. What I don't understand is that I don't have a USB hub so I cannot to save my life figure out why this is triggering blue screens and why so consistently. I don't have the technical knowhow to be able to open and read a dump file much less get useful information out of it, but surely 3 dumps is enough sample size to be able to determine the culprit?

average formula will not average

I can see three serious problems:

• The "IfError" function suppresses all errors in your formula. You must omit it while debugging the formula.
• You cannot use the "Search" function for a range of cells, only for strings.
• You are posting in the wrong forum (same as you did in January). For a formula as complex as this one you must go to a dedicated Excel forum. Remember to reveal the whole purpose of the formula when reposting instead of just casually throwing in the term
  "Average".

New Windows 10 PC Bluescreens when idle

I have a brand new build, Windows 10, Asus Z170-P motherboard, 12gb corsair ddr4, GTX 950, 1TB hard drive. Whenever I leave it idle it seems to bluescreen. This can happen after 20-30 minutes or not for an hour or more. Usually when I'm using it actively playing games it is fine. The bluescreen bug check string is various things from MEMORY_MANAGEMENT, IRQL_NOT_LESS_OR_EQUAL, BAD_POOL_HEADER and a few others.

The minidumps for all the recent bluescreens are here:

Things I've tried:

• Updating all my drivers, particularly the asus chipset drivers
  
• Running Memtest overnight (7 passes in 9 hours, no issues found)
  
• chkdisk (via windows 10 tools)
  

I really am stuck now. I took it back to the store where I bought all the parts and they said they tested it and it's all fine (they updated the chipset drivers again even though I had already done so) and for them it was running for 2 hours with no bluescreen.

If anyone has suggestions I'd be really grateful because I've run out of ideas!

Odd Bluescreen Issue

I reinstalled a PC at work recently that always works fine during office hours, but when we come in the next morning it's sitting at a bluescreen. It gave the code 0x0000007E (0xC0000005, 0x00000000, 0x8D393B10, 0x8D3936F0).

It's a fairly new PC I built myself a few months ago, it has an i3, 6GB of DDR3, SSD hard drive, etc. Nothing like this was happening prior to the reinstallation. It seems like something scheduled going on is causing this to crash. I checked Disk Defrag and it was scheduled weekly for Wednesday nights. I turned that off today, but I don't think that's the issue considering it's only scheduled for one night a week and this happens every night.

I can't imagine what else would cause a regular issue like this. Any suggestions?
