I don't visit sites of such companies so I don't know the URL and cannot, will not and shall not post a link from any of those companies. As mentioned it would have been an add.
I would suggest some hardware tests.
Diagnostics Troubleshooting
Read carefully before proceeding.
Warning
If you're overclocking your system, revert back to stock clocks now.
Note
Test the system once the overclock is removed before continuing with the steps outlined below.
Part One: CPU Stress Test
Part Two: MemTest86+ RAM Diagnostic
Part Three: Hard Drive Diagnostics

Run
Prime95 and/or IntelBurnTest to stress test your CPU.
Prime95 - Stress Test Your CPU - Windows 10 Forums &
http://www.sevenforums.com/tutorials/220743-cpu-stress-test-using-intelburntest.html
Warning
Your CPU temperatures will rise quickly while under this stress test. Keep a keen eye on them and abort the test if overheating occurs.
Make a photo of the result and post it.
Run MemTest86+ to analyse your RAM.
MemTest86+ - Test RAM - Windows 7 Help Forums
Note
MemTest86+ needs to be run for
at least 8 complete passes for conclusive results. Set it running before you go to bed and leave it overnight. We're looking for
zero errors here. Even a single error will indicate RAM failure.
Make a photo of the result and post it please.
Addition:
If errors show up you can stop the test, remove all sticks but 1 and test this single stick in each slot for 8 passes or until errors show, switch sticks and repeat.
If errors show up and you see them a lot later, no problem, the errors don't affect the test.
