I am seeing some red dots or pixels only on black areas in my monitor. However these red dots are not permanent and only appear sometimes. Sometimes there are only a few while sometimes there are relatively more in numbers. Is it for my Graphics card? I really don't think its my monitor problem. My monitor is connected to my graphics card via HDMI cord and I also have a VGA and a DVI to HDMI connector lying as extra.
Here is my configuration:
Processor: Intel i5 4690 (3.5-3.9)Ghz [Not overclocked]
Ram: Corsair Vengeance 1x8GB (1600Mhz)
Motherboard: Gigabyte B85M-D3H
Hard Disk: Western Digital WD10EZRX 1TB (Caviar Green)
Graphics Card: Zotac GTX 660TI 2GB (DDR5) [450W]
Monitor: Dell S2240L 21.5" LED (Full HD 1920x1080, IPS)
PSU: Corsair VS650W
OS: Windows 7 Ultimate 64bit (offcourse not original)
Note: Graphics card also is not overclocked and all drivers are upto date.
Graphics card setting are:
GPU Clock: 993 Mhz
Memory Clock: 1502 Mhz
VDDC: 950mV
Board Power Limit: 100%
 
Thats a pretty old Card man, Try the other cables and see if it happens, cause they port might be broken on the graphics card. If it happens with the other cables, then you might need a new graphics card. But first try a different moniter aswell, with different cables. if that doest work, try pull out the card and plug it back in. who knows could be the motherboard.

But man if you wanna play games you have to upgrade your card.
everything else is perfect. try get a GTX 950 card, or for a cheaper card try a GTX 760, or 770. But the best price to performance, you can get GTX 960 Around $200USD
 


I will try using different cables. I use HDMI because it delivers the native Full HD resolution of 1920x1080 whereas VGA cables cannot give that resolution. Also I bought my pc only a few months ago. So cannot opt for a new video card right now. Is there any way by tweeking the seeting of my graphics card? For ex: If I lower the clock speed by a few Mhz, will it solve the matter?
