PC Stuttering mouse/audio/video lag

Yeah i checked the registry and that was indeed set to 1 so thats all good. I can't convert the file into a txt file now, it just creates a 0KB empty txt file, something strange is going on? I can take a screenshot of the entire summary page instead?

The error I receive is xperf: warning: applying restriction of access for trace processing.

But it thinks it has executed properly?

You need to run that last xperf command in an elevated command prompt also :)

You can also take multiple screenshots of the summary page also if you wish.

The biggest offender on that chart is nvstor.sys.

This is a sys file related to the functionality of the NVIDIA® nForce 570-SLIc chipset that is on your motherboard. (ergo the heart of your computer)

There are two ways we can deal with this problem:-

One, would be to procure updated drivers for the motherboard, and update the chipset drivers to see whether the issue would resolve itself.

Two, try moving your boot drive to the 1st SATA port on your board (If it isn't already there)

(and three, which is the one everybody dreads to hear... replace the motherboard as it may be going faulty...you did mention is only started happening very very recently...with no added devices or driver changes to your system right?)

To validate my hypothesis for option 3, try rebooting your system in Safe Mode and see whether the issue still occurs... if it does.. I'm sorry but it's the most viable option.

Its fixed Only trouble is, I am too lazy to open my pc up twice, so it could either be the amount of dust I removed from around the HD and front intake fan, the fact I swapped it from SATA 1 to SATA 2 or just disconnecting and reconnecting the cables. Ran a quick check using that xperf thing you told me about and DPC only reached 4% max during 1 minute, with the highest reading coming from USBPORT and nvstor about halfway down the list. Could have been overheating, as I only read GPU and CPU temps which both have their own fan. Thanks a bunch for helping me track it down to the HD, I'm one happy guy now +++rep.

Wow.. so a simple SATA port swap settled it?
Thats great news!

Thanks for the feedback, I was wondering where you've been!
