Skype causing stuttering/instability?

This is my second incredibly weird question this week, but I'd be really grateful for any help anyone can offer. I've been experiencing some very strange instabilities on my system recently. Mostly it's been sporadic stuttering/slowdown - to the point where moving the mouse across the screen takes ten times as long as it should. This is an overclocked 4670k with 16GB of RAM so slowdown when the most intensive thing running is Firefox simply should not be happening. I've discovered that this only happens when Skype is running.

I have refreshed Windows, reinstalled Skype, set it to below normal priority in task manager, and still, when it is running, there is a chance that the computer will slow down to a crawl; ending the skype process fixes the problem immediately.

This has only been a problem with the system overclocked; returning to stock speeds and voltages seems to fix the issue, although I can't be 100% sure since it is, like I said, sporadic. I'm running an otherwise very stable 4.1GHz at 1.85V, with the ring clock at 3.8GHz. I can run Assassin's Creed IV with no issues but Skype kills my stability, which to me makes absolutely no sense. Anyone have any theories?

go into skype tools under privacy settings disable select browser cookis and the microsoft ads then clear skype cookies


the problem though is your voltage way too high i believe you are only supposed to go to 1.3v or 1.35v max when overclocking on haswell
someone correct me if im wrong

I've run IBT and AIDA64. I've heard Prime95 can do bad things with Haswell's adaptive voltage, I'm sure there's disagreement over whether that's really an issue but I don't want to chance it when there are other options out there. Anyway, every test comes back fine.

No problems in the last couple of days except with Skype itself, but I'm going to reserve judgment for another few days since the problem was intermittent (occurring anywhere from twice a day to once in three days) before.

I have had so many issues with Skype that I now refuse to reinstall it much to my friends dismay. The first time I tried installing it all flash videos stopped working even after reinstalling the flash player. After rolling back to an pre skype restore point everything was fine again. A few months later I tried again, this time my system would randomly become unresponsive and/or sluggish.

I say down with Skype!

i personally have had issues with skype causing stuttering issues and those are the fixes i have found that affect the whole system performance unfortantely i havent found a fix for the program itself. you could try a older build of the program

Had a similar issue today, but wasn't as serious - I was actually able to start task manager and kill skype rather than having to hit the reset button as I was having to do before.

I used to use Trillian as my Skype client and only start up the Skype application itself if I was doing a video chat. Sadly, it seems that when Microsoft integrated Skype with Live Messenger and Microsoft accounts, the API Trillian had been using stopped working, and Trillian is (understandably) refusing to resume development until Microsoft stops changing how Skype operates every few months.

If anyone knows of a third-party Skype client that currently works, do tell.

No, I was thinking of a client that uses the Skype network/api. I actually got Trillian to work in the end so I guess we can consider this thread closed. Thanks for trying to help everyone.
