Huge FPS drops after idling for 2 minutes

[talky]

Hello everyone, I've been looking for a solution to my problem for 2 days now, and sadly I haven't found anything.

THE ISSUE:
From 3 or 4 days my PC drops quite big ammounts of FPS (from 60 to like 2), not only in games- everywhere. When I watch youtube, facebook or other stuffs, not mentioning notepad. It happens only after ~2 minutes of idling (no input: mouse or keyboard). When I move the mouse even 1px away, everything comes back to normal. The only idea I have is that Windows Updates I did recently (4 or 5 days ago) may cause the problem. I would be glad to hear from anyone who had this problem and resolved it.

MY SPECS:
AMD Athlon 64 x2 5600+ 2.9 GHz
2GB RAM (2x1GB)
nVidia GeForce 9600GT 512MB
2x HDD WDC 80GB
Windows 7 Ultimate 32-bit.

Sincerely, Adam Cromwell.

Check your power options in the control panel.
I suspect that some components are sleeping after 2 minutes of inactivity.

Oh, I forgot mentioning about Power Options. So I am using High Performance (tried Balanced- the same, Power Saving crashes the whole W7 so I have to hit hard reset). And now Power Options:
- Require a password on wakeup: Active
- Turn off hard disk after: Never
- Desktop background settings -> Slide show: Available
- Wireless Adapter Power Saving Mode: Maximum Performance (tho I have no WiFi)
- Sleep after: Never, Hibernate after: Never, Allow wake timers: Enable
- USB selective suspend setting: Enabled
- Power button action: Shut down
- PCI Express Link State Power Management: Off
- CPU Minimum state: 10%, Maximum state: 95% (I have to use 95% because of CPU overheating at 100% usage- but it's not the problem), Cooling policy: Active
- Turn off display after: 15 mins
- Multimedia-> When sharing media: Prevent idling to sleep, When playing video: Optimize video quality
- IE -> JavaScript Timer Frequency: Maximum Performance.

So I guess Power Options aren't bad.

This is the first time ever I have these drops, many other problems happened with W7 but never so weird and so mysterious...

OK, I think I finally have found the solution! This was the malfunction of nVidia programmes. I went to the Event viewer and saw that something like nvstream causes errors. So I went to msconfig (START and type msconfig), then tab Services and unchecked NVIDIA Streamer Service. Applied, restarted and voila! No drops! I hope I will help someone in the future with this thread.

Good job!!
I wonder why it only caused a problem after inactivity.
