Something is wrong pleas help...

[vansenigma]

I just got a nvidia gtx 670 2gb about 2 weeks ago, the first week it was awesome. I play games on high, use high quality enbs for skyrim. But recently, it start to slow down...

? Why would it slow down all of the sudden, it was fine. Also my driver is up to date. I open my computer to clean off dust and check to see if everything was fine. My graphic card is fine, is not overheat nothing was dirty.

I try running games on low to see the difference, it was the SAME. Even when i ran games on low it was still the same. What is going on here? please help.

Have you heard of a program called CCleaner? It cleans up your computer registry. What I would suggest is you download that from piriform (its free) and then run it. Then check your games, if it is still slow, uninstall the Nvidia drivers, and run CCleaner again. Then reboot, and then re-install the drivers.

I've never personally seen PC starting to slow down in relation to the PSU, but it won't hurt to check. PSU can do really bad things. So just to make sure that your gpu is getting enough power. Edited November 25, 2012 by Bandit Ngebak

My brother got a 670. When it was stressed it'd dump the fps down to the mid 20s. It turned out that his PSU was too weak, so the 670 was scaling its clocks way down to avoid overdrawing power. His PSU started to fry eventually, so he had to replace it. I'm not saying that this is your problem, as registry errors and the like can easily cause terrible framerates. But it's possible that the PSU is the issue.

ty for all of your help ill look into it more =/

Don't take it the wrong way, but this sounds like just folk conjecture. No components of the PC even know how the PSU is doing. A holdover from early ATX days, the PSU doesn't communicate with the system, except to turn on and off, and even that is simply shorting two wires.

It isn't the PSU, they simply die without warning.

 

My guess is this may have been caused by updating the drivers. 300 series NV drivers are buggy, esp. in that regard.

Try to uninstall the drivers completely, also uninstall ENB, restart, then install the last driver from scratch.

He should use CCleaner in safe mode to be absolutely sure the drivers are gone. They may not be the problem but at least this way he (and us) can be absolutely positive that they weren't.

Say what you will, the fact remains that the PSU began to shut down the pc shortly thereafter and a new PSU resolved the problems. Clearly the PSU was the root of the problem, even if a graphics card is unable to communicate with it.

A graphics card can not automatically manage itself to lower its power draw because it feels the PSU isn't powerful enough.

It has no way of knowing it. No parts of the PC have any idea what the PSU is or if there even is one.

Unless you have that one AX1200i with Corsair Link, and even then it has zero software of firmware support.

That is not the same. PSU failures such as shutting down due to OCP are, of course, caused by the PSU, in this case at least.

They may be preceded by a short period of severe stuttering and freezing if the PSU begins by failing to deliver an acceptable voltage and components have to restart. But a poor PSU does not cause persistent low performance without any issues otherwise.
