Computer Constantly Stuttering Possibly Due To Malfunctioning Usb Port.

Hey guys,

My computer started stuttering a while ago after I moved it to another room. The stutter happens everywhere, on the desktop, watching a movie, browsing the web, games and its constant, sometimes I get lucky and there is less stuttering and sometimes there is a lot but it never goes away.

at first I thought it could be malware so I scanned my computer with malware bytes, superantispyware and spybot S&D. I did find some malware and I cleaned it up but the stutter is still there.

I suspect that the cause of the stutter is actually a broken USB port. I accidentally messed it up one time by pushing in a USB the wrong way and now the port doesn't look so good, the port still works but I have to keep whatever I plug in at a steep upward angle for the computer to recognize the USB, if that makes sense.

Usually I have my keyboard plugged in there and the other day the keyboard suddenly stopped working and there would be a lot of stutter (almost like the computer is trying to connect with the keyboard again) for a few moments making the computer unusable and then the computer would suddenly recognize the keyboard again and the stutter would go back to normal. This happened several times in a row until the keyboard started working normally and the stutter went back to normal and I could use the computer again.

So that is why I suspect the USB port to be the cause of the problem.

Even if I don't have anything plugged in to the USB port the computer still stutters anyways.

How do I fix this?

 

There are several things we need to know:
1. What is the exact Operating System? (We always need to know that for any help)
2. Is it a laptop, tablet or desktop system?
3. How many USB ports do you have?
4. Re Malware: You can't be sure that your system is clean except by running ALL the required steps in the MajorGeeks Read & Run Me First Guide and when finished attach the scan log text documents to a new thread in the Specialist Malware Forum (not here) when a trained expert will advise you further.
5. To check if there are any corrupt System Files, and repair them, run the System File Checker:
https://support.microsoft.com/en-gb...er-tool-to-repair-missing-or-corrupted-system

6. If you need to replace that USB port there are many guides and video tutorials online to do that.

 

I see that you have now given the answers requested above, in your new Specialist Malware Forum thread instead of this one.

If when the trained malware expert replies, and you get to the end where there is no malware, you will still need to run point 5 in the post above, in fact you can do that right now while you wait.
Subsequently, you will have to repair/replace that broken USB port or not ever use it.

 

Hello,

Sorry for not mentioning this originally.

I have a desktop computer
Windows 7 64bit,
Intel core I7- 4770 CPU
GTX 780
16GB of ram

the broken USB port is at the front of the computer on the right side. there are 2 USB ports there and I think there are 8 more at the back of the computer.

I did a system file check and it found corrupt files and fixed them. Ive uploaded the log for that here.

Ive also done all the malware scans and posted the logs in the malware section.

 

That's great - it rules our system files.
Just wait for the feedback on Malware and if the problem persists even after all malware cleared, sounds like a USB port repair.

 

Definitely go through the malware removal process first.

If that happened to me, the first thing I'd do is open the case and make sure all the plugs were tight and everything was well seated. I'd also check that the RAM was properly seated. It could be that moving it has loosened something.

Another thing I'd check is the outlet it is plugged into. (I have a tester I use to check wiring). Perhaps there is something wrong with that particular outlet.
If possible, run a heavy duty extension cord from where the computer is located to where it was originally plugged (if you don't have a tester). If the computer doesn't stutter, then you know the power source isn't reliable.

If you have it plugged into a surge protector, remove it for the moment and plug it in directly in the wall. If the stuttering stops, get a new surge protector.

 

One thing I forgot to mention in reply to your post below, Windows Side Bar gadgets in Windows 7. Many of them were corrupt in the SFC scan. But more importantly they were got rid of by Microsoft in Windows in 8 and above as they are a HAVEN for Malware.
If my system, I would remove all sidebar gadgets and, if possible in Windows 7 (I don't remember as it's so long ago I used Win 7) I would uninstall them.
IoBit Uninstaller FREE in its 'Windows Apps' settings is excellent for removing them cleanly.

 

I opened the case for a look. Everything looked OK as far as I can tell. Like everything looked like it was plugged in pretty good, but Idk I'm not that good with hardware.

I've also changed the outlet where I plug in the computer nothing really changed though. I don't have a power surge protector.

I also uninstalled all the sidebar gadgets.

Nothing seems to make it go away lol

but I have noticed that sometimes if I mess around with the settings on a software it might make that software stutter a lot less. For example I remember messing around a lot with VLC a while back because I couldn't watch a movie from the constant stuttering. I don't remember exactly what setting I changed, but there was one thing I did change and then suddenly all the stuttering was gone on VLC and I could watch a movie normally. its still like that now but other programs like GOM, and windows media player, and streaming YouTube videos still stutter.

also I think I turned off windows Aero, and changed my desktop theme to windows XP and that got rid of most of the stuttering on the desktop. Before that the mouse would stutter a lot on the desktop but now it doesn't do that anymore.

for some reason chrome and Firefox stutter when I'm browsing but Opera doesn't.

and different games have stutter differently too and it seems unrelated to how graphically intensive the game is. an Old game might stutter more than a newer one for example. for Some games the stutter is barely noticeable but some others can be unplayable.

 

Let's wait until the Malware forum thread is 100% complete and finished.
It can then be looked at as a software issue, or maybe you will be looking at a RESET of Windows.

 

Hey guys,

My computer is now malware free.

However I still have some stuttering. There is a lot less of it though so using the computer is much more bearable. During the malware removal I unplugged all the USB's at the front of the computer and moved them to the back. So Idk if that is what made the computer less or if it was the malware removal.
