Asus g73jw - Stuck on troubleshooting the freezing problem

Hi all
Havn't been very active on this forum, i'w mostly come here when i'w had problems to see if anyone else found a solution since this computer has been more or less of a pain since i got it.

First problem i had was huge lag spikes caused by the stock hybrid disk that came with the laptop, I ARMed id and they replaced it. didn't take long before it started acting up again but after getting a SSD instead that was "solved".

second problem i'w had is the spontaneous shutdowns that could happen anytime it seemed, this seems to have been solved with the new realtek drivers as posted in another great topic on this forum...

But the THIRD problem i have i cannot for the life of me figure out what might cause it...
When i stress the computer somewhat like playing games, it often freezes completely forcing a hard reboot.

First i blamed the fans thinking it was heating related, opened the laptop and gave the fans/blow holes a good cleaning... didn't help though
Second thing i did was get a cooling pad since i often (always) have the laptop in my lap when gaming... didn't help though

So now i installed Speedfan and enabled logging to be able to get back in after a freeze to see the temps, they seem to be really good though:

Code:

GPU	HD1	HD0	Temp1	Core 0	Core 1	Core 2	Core 3
53,0	30,0	37,0	56,0	56,0	56,0	56,0	56,0

so now i'w given up on the temp issue since clearly thats not the issue.

I'w been looking through the "Event Viewer" in windows to see if maby windows picked something up (for once)

All i find is this:

Looking through all the other logs in the event viewer at that specific time i found NOTHING.

frankly i have no idea how to troubleshoot this anymore, i might dualboot linux for a while just to have crashdumps and other options.

I'w been searching these forums for this specific problem but i seem to just find the "computer freezes when idle" thing that was addressed a while back.

Does anyone have any clue how to continue from here?
