Monitor Not Working/Green Dots on the Screen - NVIDIA GTX 750
I am having a problem that started recently, probably within the past 2 months.
Quick run down of the system:
HP Pavilion 500-164 stock except for:
- NVIDIA GeForce GTX 750 revision A2
- Corsair PSU (I believe it was a 400 watt, can't remember the exact model)
- 250GB Seagate SSD
- 32GB of DDR3 Corsair memory
The stock components:
- AMD A8-6500 CPU
- AMD MSI-2AE0 Motherboard
I have had this combination (except for the memory, that is a recent change) for a couple years now, with no issues. Now I am encountering a graphics issue. I have three monitors connected (all different kinds, a Dell and two HP's) to the NVIDIA card, using all three ports, the DVI, HDMI, and a Display port. I am using convertor cables, as the monitors are either DVI or VGA.
Here is what is actually happening: The monitor connected to the display port doesn't always work. When I boot the computer, it will randomly not receive signal. If I restart the PC, it might start working again. I used to be able to unplug it and plug the cable back in. That doesn't work all the time now. I am also starting to have issue with the monitor on the HDMI port, except this one will show up either 100% green or with green dots scattered over the monitor.
I am going to pickup some new cables today to see if they are the issue, but I doubt it will be such a simple fix. What do you guys think? If you need any more information, I will be here.
