L702x All games playing in slow motion

I have an L702x, core i-7, 3D, gt555m, 12gb, SSD, etc. Anyway, lately this started happening randomly. All the games I play are in slow motion. I'm getting high frame rate, but from the very beginning the motion is slowed down about 400%. And the audio is really weird. It's not like I'm lagging and the PC can't handle it. I'm running Win7 SP1 with all the latest updates. My CPU temps go as high as 50-70* C. GPU 50-59*. I just did a clean install with the latest nVidia drivers released 8/9/11. I've tried closing all running apps but it doesn't make a difference. Steam games and Battlefield 2 are a couple it's affecting. Sometimes I reboot and it's fixed. Other times it takes until the next day. I'm an IT manager and this has me stumped.

 

I powered the laptop off, unplugged the battery, held the power button in for 20 seconds, then powered it back on. This fixed it. Now games aren't in sssssllllooowwww motion. Hopefully this helps someone else.

 

It sounds like maybe the Nvidia GPU isn't switching on for some reason, maybe? Or perhaps some background process was eating up CPU resources temporarily which rebooting killed?

 

But I have the 3D screen, so Optimus shouldn't even be in play. The games are running at high FPS, it's not laggy at all, just everything is super slow mo. I think it's some kind of hardware glitch that required a full power reset. I had rebooted probably a dozen times before that to no avail. I keep my laptop powered on 24/7.

 

Many laptops throttle GPU performance to extremely low levels (especially Dell) to save battery life if you don't use the recommended wattage or if it gets unplugged. I can tell you my Vostro 1500's 8600M GT is throttled to the lowest levels if I use a 65 watt adapter or run it on battery (I found out by when my AC adapter plug got loose when playing MW2).

 

But again, throttling GPU performance should lead to reduced FPS. I assume to OP has something constantly showing the fps on-screen to know that it is allegedly NOT an fps issue. In which case this is odd.

 

Yep, FPS is on screen. I can turn at a normal rate, but walking and jumping is really slow. It's really odd. Since completely powering off the system was the only solution, I think it might be some sort of GPU hardware glitch.
