Hello,
I have just made a major upgrade to my computer and I have the following problem:
Every now and then, the screen goes blank for 1-2 seconds and then goes back to normal.
I have windows 8 pro upgrade installed and tried both the motherboard's vga drivers (V 9.17.10.2884) and Intel's latest drivers (9.17.10.2932) but the problem persists.
The previous vga was a SAPPHIRE RADEON HD 4850 512GB, the drivers were fully uninstalled.
Configuration:
Motherboard: ASUS P8B75M-LE
CPU: Intel i3-3225 with HD 4000 enabled
RAM: 2x4GB 1600Mhz Kingston KHX1600C9D3B1K2/8GX (stated as compatible from ASUS for this motherboard)
PSU: 500W Chieftec
Monitor: LG 21.5' on DVI (1680x1050)
OS: Windows 8 64bit
