Windows 10: Laptop crashing and rebooting

Hello,I would be very thankful for helping me fix my laptop.I brought my laptop to university, turned on then signed in and it crashed blue screen, rebooted and crashed again, this happened a few times until it booted to repair screen and I chose for windows to try to fix this problem, after that it booted with a notification that it uninstalled some updates don't know where to look what it uninstalled and it worked after that, came back home turned on laptop and after a minute it crashed, rebooted and worked fine. Here's some information about the crashes and reboots from Reliability Moni

I suggest you run rthdribl > http://www.daionet.gr.jp/~masa/archives/rthdribl_1_2.zip
Increase the window size step by step and watch your vga temps permanently.
What happens?
If it crashes, run at stock speeds as suggested before and retry.

P.S.: When your system locks, does the display signal turn off after a time?
Stuttering sound or no sound at all when freezing?
What X1800XT model do you own exactly?

 

Random laptop crashes in games.

thats alright bro, If it does turn out to be an overheating issue, I'll let you take all the credit for suggesting it
