Hi i own an Winfast Gtx 560 ti gddr5 video card. Bought it 2011 december.
My problem:
once when start gaming with my computer randomly fps drops/lags occur inside games with any settings in low/high with msaa on or off with high and low resolution.
also sometimes but it's truly rare losing screen/computer freeze.
already found out my problem is Video Card core/shader clock jumping down like
from 822 to 450 to 153/53 etc
shader clock from 1650 to 600/320.
and sometime memory clock aswell 2004 to 357
i never overclock

Well this problem started about 1 week ago before never been done.

what i already tried:

checked proccesor with stability test : no problem
checked memory sticks with test : no problem
Checked hdd with test : no problem
Reinstalled windows and using old drivers.
at bios every power saving set off.
checking temps but they all normal.
tried declock core/memory
from 822/2004 to 650/1600
tried change video card to other one everything was fine.

my config:
psu : Gygabite superB 460 w
mainboard: asrock 985gm-gs3 fx
processor: Phenom II x4 955 Black Ed 3.2mhz
memory sticks 2*kingstone hyperx 2 GB 1600mhz
Hdd: 500gb Western Digital 32mb

What can occur this problem pls help if u can thx a lot. sorry if i spell something bad but my english not perfect.

Basically your graphics card frequencies are changing randomly in the middle of games.

Two things I can think of that will be causing it, the cards overheating and its throttling itself to prevent burning out, or your going over the power limit and again its throttling itself to keep inside a TDP limit.
Download a program called MSI Afterburner and another called Furmark. Run Furmark while monitoring your temperatures inside Afterburner to see if their fine (say below 80ºC) after 10min of furmark running. At the same time keep an eye on your core/memory clocks, if their fluctuating and the temperature is fine, its probably a TDP limit. Afterburner should have a slider giving you the option to increase the Power Limit, just max that out.

could be a driver problem, download driver fusion and the latest nvidia drivers.

install driver fusion.
uninstall nvidia driver but do not restart.
run driver fusion nvidia driver cleaner and restart.
install latest nvidia driver.

see if this helps first.

already tried furmark. it see able core drops every 1-2 sec. and using msi afterburner this is how i find out clock droping. there is no option to me for power limit % change.
drops done every temp like 50 -75. long funmark test sometimes cause my pc to power off and don't let me power on like 5min

do you have another powersupply you can try? im wondering if its the powersupply if the gpu is not overheating.

otherwise it could just be that the gpu has broken.
a friend of mine had a 560ti that just went on him in weird ways, he had it as his primary card in an sli system and kept getting strange performance in games that was sometimes better than 1 card or worse than 1 untill he removed the faulty card and used the secondary card as his primary and his performance was as it should have been with 1 card.

he tried the faulty card on its own and got worse performance than it should have had and random performance.

if it is still in warranty i would get it replaced, it sounds like it has developed a hardware problem.

especially if its throttling the card randomly when its only hitting 75c
