Windows 10: Screen freezes, followed by automatic unexpected reboot

Beginning yesterday, my computer has started to freeze and unexpectedly reboot while watching videos, occurring four times in the past 26 hours or so. Although most instances have occurred in the early morning when it was cool, the past several days have been exceptionally hot where I live. Without air conditioning, I'm concerned that the heat may have caused damage to hardware prior to the crashes.I've found three "Error" or "Critical" system events that are likely related to the crashes, copied below. Any insight on what my next steps should be to solve the issue?Thanks!KrisEvent 1: ErrorThe

Internet browsers randomly freeze PC, automatically reboots

This issue began happening a few days ago. I am experiencing a complete system freeze following an automatic reboot. This happens only with internet browsers (tested with Firefox, Chrome, and Edge) being open, typically while loading a webpage or having
more than one tab open, but I am finding no specific pattern to trigger it as freezing occurs within minutes of use up to a few hours.

Ive had some programs become unable to open such as Malwarebytes and Nexus Mod Manager as a freeze happened while loading in a program, a complete reinstall fixes the issue.

Steps I have tried:

• Delete browsing history via Control Panel Internet Options and browsers
• Cleaned PC of dust - hardware temps are also good
• Virus(Eset NOD32) & Malware(Malwarebytes) Scans - no negative results
• msconfig services check - good
• msert.exe microsoft security tool - no negative results
• RAM check - good
• Drivers up to date

Any other ideas?

reboot/freeze problem

my computer runs fine for about 20-30 minutes and then reboots/freezes(sometime it reboots, sometimes it freezes)
i have an evga 680i A1 board, 4x1gig xms2 dhx, q6600, 2x8800ultra's, 2x150gb raptors, pci-e wireless n card.

i have tried running the computer at stock speeds and voltages and have the same problem, so it's not an overclock issue.

it seems to be a software problem. but where do i start? the computer run @3.6ghz can run all night(9hours) orthos stable, but when im using it, it locks up every 20-30 minutes.

any suggestions?
