This started a few days ago. About 3 min. after logging into Windows. Swapped out GPU with exact same model can now get 15-20 min. Lines do not appear in safe mode. I use hardware monitor and temps for GPU idle at 54°C and when gaming don't exceed 74°C, voltages don't change. Any help would be appreciated as I am out of ideas.
Specs:
Laptop - Sager NP8760
OS - Win7 Pro
Motherboard - clevo w870cu
CPU - Intel i7 740QM
GPU - Ati mobility Radeon HD5870
Ram - 8GB
What I've tried so far.
-Using a different power cable.
-Using display driver uninstaller to uninstall drivers. Installed catalyst control center and crimson edition using drivers 15.7. 1 and 16.2.1.
-Using "Who Crashed" to see if it could help. (Custom, third party)
-Using external monitor.
-Lowering resolution on monitor.
Thanks in advance.
