Because the error suggests that it may be heat related, I tried configuring the max cpu power in windows power management to 95% and then to 85%, but that didn't help (the max cpu speed was 2.3 and 1.9ghz this way, instead of 2.9). Also nothing is blocking the vents in any way, and the laptop is only a few months old, so it's not clogged with dust.
Updated the bios to latest version a week ago, problem still persists.
Also did a mem. check when the system starts a while ago that also didn't return any issues.
