Hey guys ! Gosh I havn't posted here in like 10 years... feels weird, but anyway, I have a Lenovo y50 touch Laptop with the following Specs: Intel Core i7 - 4720HQ Intel HD 4600 Nvidia GTX860m 2GB (Maxwell) 8GB RAM @ 1333MHz 1TB SSHD Windows 10 So my problem is that a while ago, i put my computer to sleep after playing an hour of Metal Gear solid V and once i took it off sleep, the screen had all sorts of different distorted colors, and after a while, the screen totally failed. Then, after replacing the screen, what happened i realized that I would always get a BSOD error on startup : DCP_WATCHDOG_VIOLATION. Went into Bios, switched to intel GPU, everything started fine. Reset the Laptop to factory settings, and downloaded all drivers, downloaded the most stable Nvidia drivers at the time. Re enabled the Nvidia GTX GPU in bios, then tried installing the graphics card and it always crashed with the same error mentioned above. Installed Windows 10, same error Does my GPU have cracked solders? Do you think I can Reflow the GPU with a heat gun for 3 mins @ 220 degrees 'C ? Haven't tried it yet, unless someone else has an ideas ? - Btw Laptop is out of Waranty. P.S Gaming with the Intel HD 4600 is pretty depressing.
