Strange Behaviour

Every morning my PC boots normally then freezes after about five minutes. I power it down completely then re-start it and it usually then operates correctly for the rest of the day.

Rarely there are BSODs with inconsistent messages - by which I mean that these are rarely the same,- "reference by pointer" being one.

I have cleaned the machine physically, re-seated components, checked for infections, updated drivers, run system file scans, reinstalled windows.. I'm beginning to think that there may be a motherboard issue but would welcome any thoughts.

Please provide this information so we can provide a complete analysis (from the Pinned Topic at the top of the forum): http://www.eightforums.com/bsod-cra...e-screen-death-bsod-posting-instructions.html Please use Option 1 as it provides Event Viewer logs.

Also, to help with figuring out the freezes, Please do the following:
- open Event Viewer (run eventvwr.msc from the "Run" dialog))
- expand the Custom Views category (left click on the > next to the words "Custom Views")
- right click on Administrative Events
- select "Save all Events in Custom View as..."
- save the file as Admin.evtx
- zip up the file (right click on it, select "Send to", select "Compressed (zipped) folder")
- upload it with your next post (if it's too big, then upload it to a free file-hosting service and post a link here).

FYI - If we're looking for Event ID 41 errors (unexplained shutdowns), there's more info on that here: http://support.microsoft.com/kb/2028504

While waiting for a reply, please monitor your temps with this free utility: HWMonitor CPUID - System & hardware benchmark, monitoring, reporting

Finally, although this is experimental for me, you may want to try this report:
Press Win and R to open the Run dialog
Type in "perfmon" (without the quotes) and press "Enter"

In the left hand pane:
- expand "Data Collector Sets", then expand "System"
- Right click on "System Diagnostics" and select "Start"

Wait until the report shows up in the right hand pane (approximately 60 seconds)
If you're impatient, left click on the latest report in the left hand pane and you'll see the "Generating report..." status message.

- expand "Reports", then expand "System"
- left click on the latest report (to select it)
- right click on the latest report and select "View", then select "Folder
(the reports are numeric by date, then by number of the report that day. For example, the 6th report I ran on 30 September 2014 is named "SAMSUNG_NP780_20140930-000006")
- scroll down to "report.html" and copy/paste it to your Desktop

- then Zip it up and upload it with your next post. If the report is too big to upload, please upload it to a free file-hosting site and provide a link to it here.

Just FYI - the reports are located at: C:\PerfLogs\System\Diagnostics\<report name>\report.html
