Hi all. The Pc I built about a year ago is as follows:

OS: Windows 7 Home Premium (x64) Service Pack 1 (build 7601)
CPU: 3.30 gigahertz Intel Core i5-2500
Motherboard: Gigabyte Technology Co., Ltd. Z68AP-D3 Bus Clock: 100 megahertz
RAM: 16302 Megabytes Usable Installed Memory
GPU: NVIDIA GeForce GTX 560 Ti

Everything was working reaaaaally smooth, to perfection. About a month ago, I started having low FPS while playing World of Warcraft.
Until now, I was playing on Ultra setting, everything maxed, in a windowed mode, with facebook games running on the background, internet radio playing, etc etc and everything was running smoothly. All of a sudden WoW started having very low FPS and slowly deteriorated to unplayable.
Now even on low settings is unplayable.
And then the whole PC started malfunctioning. Even facebook games have very low FPS. While watching High-Res videos i get breaking image etc, even internet radio sometimes breaks (if i try to do something else at the same time).

Does anyone have any ideas what could be busted so I can replace it? I'm almost sure it's the GPU but at times it feels it can be the CPU. Not really sure and I can't take it to the store for a check up.

Any help would be much appreciated!

sounds like you need to clean up the system...

What you did not mention was the hard drive(s).

I would suggest getting and running Ccleaner, then do the Windows Clean up functions, do a chkdsk on all drives, then a formal defrag. Also, blow out the dust from the system carefully using low pressure air 20PSI on so. Dust bunners are hell on a system after time.

IF that does not help, uninstall the video drivers and run Ccleaner to clean up the registry before installing a fresh driver suite from Nvidia. (that will be uninstall, reboot, runCcleaner both trash and registry, restart, install newest Nvidia suite.

IF that still does not work and maybe before get a video benchmarking application and see what FPS and temps you are getting. There is an off chance you cooked something...

Good luck.

ok so, runned Ccleaner, done defrag and chkdsk and memtest, everything seems to be working ok, also removed old drivers and reinstalled the new ones, nothing changed. also benchmarked the gpu, didn't have any major issues.
i used open hardware monitor to check the temperatures, the only relatively high temp i have is on the CPU. it's getting 85+ degrees at all times it seems

What cooler are you using? Factory OEM? or after market?

open it up and remove, clean and reapply thermal paste to the cooler/ CPU interface... if it is "factory" still I have seen cases where it dries up and does not transfer heat correctly.

so eventually I had to call a technician. He took it and he said that the problem was my hard disks. they were heavily damaged. so i told him to put a new one and so he did. he brought it back and said that he run all possible tests and that everything passed and was working really good. when he delivered it back to me, he said that when he run one of the tests, he noticed that at some point the CPU temperature sky-rocketed and he told me that perhaps the cooler i put is not the ideal for my CPU.
This is the cooler: http://www.amazon.co.uk/gp/product/B004MYFOE2/ref=oh_details_o06_s00_i01?ie=UTF8&psc=1
Manufacturer says that it is perfect for my CPU.
Then he also told me that my CPU supports only up to 16GB RAM (while me have 32GB but i have 16GB), i checked on the intel website and it says that it supports up to 32GB, so don't know what the heck he was on about......
Anyhoo, sat down today to check the now "fixed" PC and while there are some very small performance improvements, the major problem still continues. WoW FPS still very low and unplayable, facebook games are robotic etc etc...
I have NO idea what to do anymore....

My only though now is the air flow for the cooler... I have the old H50 on my system. Corsiar has a guide on their site about airflow. I followed it and my i7-2600k (OC'd to 4.3GHz) stays under 60C.

Double check the setup by following their guide...
