Sudden FPS loss

[SavageWolfFrog]

Hi,

I have a gtx 570 SC from EVGA on the 301.42 drivers. Tonihgt while playing l4d2 I suddenly lost half of my fps and dipped down to 30 fps.

Startled I quit and tested crysis 2(normally 60fps on the settings I have it now maxed out at about 11 fps).\

CS Go maxed at about 30 fps.

I went into evga precision and enabled all the monitoring software and I know for a fact that temperatures arnt a problem(rather aggressive custom fan profile) an d that it was supposedly running at what it is set to run(797mhz and such. It wasn't downclocking itself)

I restarted the computer and now it all works fine though. Does anyone know what could have caused that.

Oh and I ran a virus scan first thing - nothing.


EDIT: I have an i7-2600k,16gb of kingston ram,a gx750w CM psu, and a hitachi 1tb hdd. I havn't run memtest yet and the system is about 9 months old.

Windows is not a bulletproof OS and can run into problems releasing RAM due to out of control processes or accumulation of unneeded resources. Sometimes a reboot solves problems. If it keeps happening, then keep tabs on what is happening with the resources on your computer using the Task Manager.

will do thanks. Could a faulty PSU cause symptoms like that(it hasn't happened repeatedly and i would have figured a failing PSU would give them fairly regularly if it was the problem but I might as well ask).
