BSOD - The computer has rebooted from a bugcheck

Hello and welcome robra mate have you runa chkdsk yet if not do so in safe mode if necessary.
https://www.sevenforums.com/tutorials/433-disk-check.html < use the /f and /r options in Option 2 if necessary

Now I have a gut feeling the power problem has caused something and after a bit of searching confirmed to some extent it may be the PSU at fault so see this
UsingHW Info PSU

Download HW Info and pick the right bit version - HWiNFO, HWiNFO32/64 - Download -(copyand paste this site into the search bar) If you do not need the runninginformation in the smaller right hand panel close it. In the left hand windowclick on the + for the individual device groupings and they will open out tothe various components.

Go on opening out further until you get to the device itself. click on it andit will highlight. In the right hand window there will be a very detaileddescription of that device as in brand, speeds model number etc etc These arevery detailed and are just what is needed for searching for drivers etc.

To getthe PSU volts you need to select the Sensor button circled in yellow in the picfor PSU testing do the same and scroll down the readout as in my pic to whereit has Nuvoton = yours might be a different section name / title. Post back apic of that please.

If you want a more definitive test see this https://www.sevenforums.com/tutorials/301799-psu-test-dc-output-voltage.html butlease only use a digital multimeter and not an analogue as they injecttypically 9v into a circuit to test and into a 3.3v or 5v rail - not a good idea!!see the partial pic of the correct sort of meter in that tutorial. details ifyou scroll down that listing.

Now a good reference article is this
Voltage Rails - Power Supply 101: A Reference Of Specifications it will explain in detail what the voltages are and functions of the PSU/

I would even think about running a memtest too
MEMTEST
https://www.sevenforums.com/tutorials/105647-ram-test-memtest86.html this one you will need to make a bootable disk set the BIOS to optical (or USB if preferred) boot the machine and let it run for at LEAST 8 passes unless the errors come up straight away. Takes fair time to complete and some leave it running overnight.
When you run the memtest if the errors come up straight away a in my pic then you will need to test each stick if you have more than one and if it is only one then test again in another slot because it could also be a fault on the board.
Use the latest version but it MUST be 8 passes minimum unless it looks like the pic I have attached

Thanks for the reply. I ran Chkdsk in Safe Mode and it reported no problems. Next I'll run the HWInfo 64 program then MEMTEST. Was the "UsingHW Info PSU" reference intended to be a link to additional info?

Did the files that I uploaded provide any insight?

Thanks again.

The files I found a few vague references to memory and drivers but as I ma new to that stuff am not sure.

The HW Info stuff the pics I sent were just to let you see how they open out and really get very specific details of the components as most will just say it is ie G Skill 1600MHz but HW Info as you can see shows speeds etc etc

Now I know perhaps you cannot access for long enough but a snip of that power section or a pic of some sort like I sent of my Asus driven Ivy Bridge - the section with Nuvoton as the heading would be good as then it is possible to see what the volts are and then by using the 5% tolerance limits it either ok's or duds the PSU but if you can just send what those volts are even the Vbatt (CMOS / BIOS battery) that will be ok.
Now you might have notice in that other link - Voltage rails it mentions on page 2 the Power_Good signal that is measured at pin 8 (grey cable) on the 24 pin plug if it goes below I think without looking it is 2.4v lowest and above 6v highest then the system will not start because it is a safety measure against allowing unacceptable voltages to flow into the machine. It is a special test circuit in the PSU that tests as you power up and that test takes an extremely short time to decide whether the machine should be powered up or not and it does that by taking pin 8 to between those voltages I mentioned and keeps the machine switched on. Should that voltage limit drop below 2.4v or rise above 6v it will shut down the computer.
So you can see it can be something very simple and the PSU is very often overlooked as a possible failure issue far more than most people think for.

Ok mate the Vbatt is very low indicating the CMOS battery requires renewing- it controls the BIOS and maybe something real simple as that. Just rememberif you renew it you may have to reset the BIOS settings from it's defaultsettings ie date time etc

The other volts are ok although I would myself be happier with the 5v railbeing actually 5v and not that 4.999v but that is just me being pedantic .

The rest looks ok now only if you are curious you can check the specs onjust about any component by just opening them up it will show the volts speedsetc etc It is an excellent tool for checking this stuff.

The temps as you can see are fine and at least the RAM is sorted. So we mustkeep chipping away the problem.

Now there is another ref to a hard drive issue so once again it is worth a test now there are two tests you can run this one for starters will test the data on the platters etc etc SeaTools for Windows | Seagate

the other will test the actually surface of the drive platters and to see extent the read / write heads - see pic
Free Partition Manager for Window PC | MiniTool Partition Wizard Free Edition < excellent tool to keep

Ok mate now just what security are you using? as there are some hints about it in searches and I still get refs to memory problems/
But I have asked for help in any case.
