Stuttering Video

Hi, first post on these forums and really looking for some help here.

Basically my problem is that after a certain amount of time (1-2 hours maybe), my computer's video starts to stutter. I'll be watching a video and every half second to second the video will pause for a split second and then resume. From what I can see, audio is complete unaffected. The youtube audio works just fine even while the video stutters and playing music files is also fine. Additionally, even as I'm typing this post out, I can tell that the letters I am typing will pause as I'm typing them then appear, same with backspacing.

Here are some computer specs if they are necessary:
-Windows 7
-Toshiba Qosmio x505
-Intel i7 Q740 @ 1.73GHz (8 CPUs)
-Memory 6144MB RAM
-Graphics card: NVIDIA GeForce GTX 460M approx total memory: 4048MB

Not sure what else would be necessary, but ask for anything and hopefully I can provide it. Also I'm not that great with computers, so if you need anything else please tell me how I would be able to access that for you as well.

Thanks! Hope you guys can help me out.

One day bump, hope this is okay :S

Video of the best way to present your self and you have to try to manage your best video for your music. You have to also use some best video for affected to the music and try to download some best video for related to the best music.

Okay, thanks for the tip about bumping. I'm not sure if I understand your comment garcarstive, could you clarify?

The one thing I can think of is to check to sure neither the CPU or the Video Card is overheating. That would be because the CPU will slow down as it starts running hot to prevent disastrous overheating. If it gets really hot the computer will just shut off to prevent damage.

I have seen a CPU that had a blocked by dust heatsink cause video playback stuttering. As soon as I pulled the side off of the computer and couldn't even see the heatsink fins I knew the solution.

Good Luck
