Video stutters but audio OK 2

[MrPB]

Hello,

I re-installed Windows 7 a couple of weeks ago, but just noticed this problem: Video stops then starts, then stops (stutters), but the Audio keeps playing. This is true for local video (hard drive) and streaming video (YouTube) no matter what file format. I notice that different videos takle longer to start stuttering than others and stutter at a different frequency: Some start immediately and some take a minute or longer before they start to stutter.

I have installed all of the Windows updates and have turned on auto update. I have the latest nVidia driver for the GPU and the latest BIOS and monitor drivers. I'v also installed codecs from

and the latest flash player. None of this helped, so I'm starting to think this may be a hardware issue. Any suggestions on further troubleshooting?

Here are my specs:

Well.... I'd try VLC media player to rule out/in the hardware aspect, then personally I wouldn't go back to WMP, but at least you'd know if hardware could be the issue.

Did you load the latest drivers for the intel rapid storage? audio device? chipset of the MB? network chip? Not the ones windows loads, and not the ones from the motherboard site, those are always downlevel.

Excellent point and for sure do that first. Check device manager for any obvious problems (exclamation points/question marks). If no obvious problems, updates are still a good idea.

Tried downloading VLC - no fix.

No obvious problems in device manager, so I downloaded the latest drivers for the SSD, motherboard chipset and network controller - one at a time, checking for the problem after each one. It turned out to be the network controller driver! It doesn't make sense to me, but the problem is fixed...

Now, I can get some work done. Thanks all for your suggestions and Special Thanks to rclarke250 for the fix.

Glad you got it sorted, nice job.

Don't know why I bothered to ask the Microsoft Community folks - they never really help. I should have come here first and saved myself a few days of agony. Thanks again!
