Becoming sensitive to video judder or problem with new computer?

I recently purchased a Dell XPS 8300 which i'm fairly satisfied with. But i've begun to notice a small barely noticeable judder (video only not audio) every few seconds when watching videos (especially noticeably in 23.976fps videos and hdtv rips). After doing quite a bit of research i've learned that the judder is natural and part of the film to video process and that watching on a 60hz can make it a bit more noticeable. I'm starting to wonder if i've just become more sensitive to the judder overtime, but at the same time if this is a problem i want to get it taken care of while my warranty is valid. At the moment i've somewhat alleviated the judder with Sharks Codec's and ReClock. Also when running games, listening to music or most everything else the computer seems to work fine. Also i've made sure all my drivers are up to date and run all dell's self tests (everything came-back good).

Also another issue another i've been having is my mouse cursor seems to randomly lag for around a 1/2 second to a second randomly. I originally thought this might be related to the video issue and that the computer might be lagging, but as i said earlier the audio never seems to stutter.Any advice on how to proceed would be much appreciated .

I don't use any anti virus software, as i rarely go to dangerous sites. So windows firewall is usually enough to keep me protected. Also after start up i use Game Booster 3 which closes most non essential programs and lowers the priority of others.

 

:eek Big mistake! Having a firewall IN NO WAY eliminates the need for an anti-malware solution.

If this computer connects to the Internet, you need an anti-malware solution.
If this computer simply connects to a network that has Internet access, you need an anti-malware solution.
If this computer receives, or is used to read email, you need an anti-malware solution.
If this computer is used for on-line banking, or shopping, you need an anti-malware solution.​

I assure you, you are NOT more clever than the badguys.

Remember, the USER is always the weakest link, and failure to use an anti-malware is a major failure in the practice of safe computing! Get one now! I use and recommend Microsoft Security Essentials (MSE). Ensure it is fully running then run a "Full" scan as your first scan. This may take some time, but have patience and let it run. After the initial full, with real-time protection enabled, you can run quick scans after that.

After the initial full scan with MSE, I recommend you download and installMalwarebytes's Anti-Malware (MBAM) and run a "full" scan with that. Keep MBAM handy for occasional supplemental scanning.

Rarely? Usually? That's like saying I don't stop at stop signs because there rarely is another car coming and my brakes usually work! rolleyes

You have 64-bit Windows 7. By FAR the most sophisticated operating system yet. An OS fully capable of managing resources in the most efficient manner without having yet another program loaded, and consuming more resources, trying to tell it what to do. I recommend you dump Game Booster 3 and if you have too many programs loaded at startup, it is better to change their options so they don't run at start up.

 

Thanks for the responses . I downloaded and ran MSE/MBAM and everything came-back clean. I have also loaded up the computer in safe mode and the video still seems a bit juddery. I then tested the computer while playing Modern Warfare 3 for a few hours and the video seemed to judder while playing it. I'm beginning to wonder if the monitor might be the issue as the problems has persisted through two video cards and its only the video the lags/judders and never the audio. My monitor also randomly clicks/pops for around the first half-hour or so when its turned on, not really sure if this is normal though....


Also i'm note sure if it relevant or not but my PSU is 460 Watt.

 

I doubt the monitor is the problem but that is easy to test - try a different monitor.

400w is the minimum recommended PSU so you should be fine there - assuming it is working properly. Swapping in a known good PSU of adequate power is the best way to verify that.

According to the specs on that Dell, it supports Dual-Channel memory but you are reporting 6Gb. I assume it came with 4Gb and you added 2Gb. When? And how is that two configured (2 x 1Gb or 1 x 2Gb)? And did the video stutter before adding RAM?

Low free disk space can affect Page File performance which can cause video stuttering.

The monitor clicking and popping - do they sound like electrical pops, or pops due to expansion and contraction as the monitor materials (matter) warms up?

 

Actually the PC came with 6GB and i believe its configured 2x2GB and 2x1GB. The hard drive(s) have 348GB free space left. As for the monitor sound it could very well be its just the from it warming up. But i'm still going to buy a dvi/vga adapter and hook up one of my older monitors just to rule the monitor out.

 

I'm having a new issues that randomly occurs though i don't know if it has anything to do with juddering. After the bios and initial windows logo loading screen sometimes the screen becomes a black and pixelated . It then loads to the welcome screen while still being pixelated and then either loads to my desktop normally or just goes to a solid black screen which results in me having to reboot. The is seems to happen about once every five reboots/restarts.

 

Not sure that would be a conclusive test. If this is happening with a digital signal now, you should test it with digital on another monitor. A stutter free analog does not prove the digital side is good.

Your new problem may or may not be related. If this computer were on my bench, I would swap in a known good PSU to be sure all these problems are not power related.
