Dell laptop cooling suck ass and it never kicks in until the GPU or CPU is like 60 degrees Celsius (I only own one and it happens like this, probably not the same anymore)
Try uninstalling bloatware, cleaning your registry, and in general look to see if other people have these issues with the laptop.
I appear to be having issues installing an update for DirectX, I bluescreen with a SYSTEM_SERVICE_EXCEPTION and no solution comes up when I search the STOP error code other than to reinstall my OS. Anything I try to install that even attempts to tamper with DirectX causes it, using DirectX (D3D, DirectInput, DirectSound) is perfectly fine and I can't install certain Steam games because of this.
If I'm forced to reinstall Windows I'll probably do a Tri-Boot of XP, 7, and Linux
