hi im looking at a pc for a family member, when pc is in use after 30-60 mins pc reboots and loads advent splash screen,

 

no errors or warning, on reboot it loads windows again  but wont allow me to type, so i have tried taking out all usb devices and using a new keyboard but same issue?

 

when pc reboots, fan still running at all times, i have cleaned out pc heat sink of any dust.

 

 

when pc randomly reboots, the pc doesn't lose power and fan doesnt stop so don't believe its a power issue or a cooling issue?

 

cpu temp around 41 degrees

 

pc temp about 23

 

any help would be appreciated

Let's try looking at these 2 sets of reports (I ask for a bit more than the moderators :) :

Report Set #1)  Please run this report collecting tool (even though you may not be experiencing BSOD's) so that we can provide a complete analysis: (from the pinned topic at the top of the forum)   http://www.bleepingcomputer.com/forums/t/576314/blue-screen-of-death-bsod-posting-instructions-windows-10-81-8-7-vista/
FYI - I don't often use the Perfmon report, so if it doesn't work please just let me know.

If you have problems with it running it, there's an alternate tool here (direct download link):  https://github.com/blueelvis/BSOD-Inspector/releases/download/1.0.5/BSODInspector-1.0.5.exe

NOTE:
Please zip up the (.ZIP) files - do not use .RAR or other compression utilities. 
.ZIP is the type file that can be uploaded to the forums.

Report Set #2)  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 the "Administrative Events" heading
- 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: 

SpeedFan v. 4.5.1 and later (free from here:  http://www.almico.com/sfdownload.php ) can log temperatures in a CSV file:
You may not need to log temps - if uncertain, please ask.

To make it work (log the temps to a file) you have to do BOTH of the below:

1. Enable logging in general: Configure...Log...check "Enabled" then click on OK to save.

2. Enable logging for specific checks: Configure...Temperatures..left click on each sensor, then click on "Logged" at the bottom of the Window (for our purposes we want them all) then once you've selected "Logged" for all sensors, then click on OK to save.

The log will be located at C:\Program Files (x86)\SpeedFan

Naming: log files are named SFLogYYYYMMDD.csv, where YYYY is the year (four digits), MM is the month (2 digits, zero padded) and DD is the day (2 digits, zero padded). If a file already exists by that name, the file that already exists is renamed according to the following naming scheme: SFLogYYYYMMDD-CCCC.csv, where CCCC is a increasing number. The new file is then created with the standard file name scheme.

Notes: whenever you change the options related with logging, SpeedFan starts a new log file.

NOTE:You may want to turn logging off when we're done - as I don't know it's impact on performance or on the system.
