Hey everyone i was hoping if you would be able to help me with an issue I am having with my PC.

My old graphics card was the Nvidia GT 230 1.5gb and it worked fine until it developed a constant blue tint to everything on the screen, I replaced it with the ASUS Nividia GTX 550ti and now I find that games like Fable TLC and Skyrim has on average lower fps then before but games like League of Legends work fine. I installed the new drivers from the disc that came with the graphics card and updated it to the latest driver on the Nividia website.

My specs are:

Motherboard: Foxconn P43AL
Cpu: Intel Quad Core 8300 2.5ghz
Graphics card: Asus Nividia GTX550ti
PSU: Antec earthwatts green 650W
HDD: Seagate Barracuda 1tb 7200rpm

If you need more details I will do my best to oblige, can anyone please help me with my problem?

Thank you for reading.
