Blank Screen In My Computer Monitor Screen
Hi! I bought a new sound card and video card. Installed it and every thing's seems to be working fine. I left it and went back though it's just a matter of moving the mouse or touching keyboard will do. It is frustrating I always have to restart my computer every time this happens. How to fix this? Do I have a bad monitor? Do I need to buy one? Did I installed the devices improperly? Can you provide me step by step on how to eliminate this problem permanently?
