Hi,
to help you best we need to see the actual dump files. As your machine isn't creating them please make sure your settings are set like thus:
Open the run application.
Type sysdm.cpl in the run box and click ok.
Look across the top of the system properties box for 'Advanced' and click that.
Look for 'Startup and Recovery' near the bottom and click 'settings'.
Near the bottom you'll see a drop down menu under the heading 'write debugging information'.
In the drop down menu choose ' small memory dump (256KB)'
Under 'small dump directory' make sure it says %SystemRoot%\Minidump.
Click ok and your good to go.
Other reasons for no dump file can include no pagefile or one that's below 200mb so if you changed it return to default values.
You will have to bsod again before a dump file will be created. Once you have some dump files please read the thread below as it will help you to collect the info we need.
How to ask for help with a BSOD problem This bugcheck can mean hardware failure although if your overclocking please return to default values and see if the bsod stops. This bugcheck can often be attributed to failing RAM as well as an out of date Bios. Once I see the dump file i'll be able to tell you more.
Windows does have a memory testing app but it can miss errors and the best app for the job is Memtest86.
If you open the link below you'll see you can run Memtest86 in two ways. You can either burn it to disk or install it onto a USB drive it's entirely up to you. You'll then need to enter the bios to change the boot order so you can boot from either the Disk or USB stick you have Memtest86 on.
You must test for at least 12 hours unless it becomes obvious there is a problem straight away (you'll see errors outlined in red.
