Mouse lagging - PSU too weak?

post #1 of 5
Thread Starter 
Hey there!

I got a strange problem... pretty hard to describe without fluent English speaking skills but I´ll do my best! ;-)

My mouse starts "lagging" sometimes. I move the mouse and the cursor needs 1-2 seconds to move a bit, then it stops again, moves, stops, moves,...

Things I figured out so far:

- When I once turned on my external USB-HDD the mouse instantly started lagging. It didn´t stop lagging when I turned the HDD off again and it didn´t start when I turned it on again.

- When the mouse was lagging I pulled out two USB2.0-devices that were plugged in an USB3.0-port and the mouse stopped lagging. When I put them back in the lagging did not start again!

- When the mouse was lagging I turned my speakers off and the mouse stopped lagging. When I turned them on again the mouse started lagging again.

- Sometimes the mouse just starts and also stops lagging without any special "trigger". Even a reboot cant help then!

- There may be no issues for weeks and then suddenly, out of nowhere, the problem comes up!

- Never had any problems during gaming yet!

- The problem is not related to system load! Im at 0% CPU and low HDD usage when it happens.

USB powersaving is turned off, Im not using an USB-hub, the mouse itself isnt defective, there are 6 USB-devices connected to my pc.

May my be PSU to weak to power my computer and so the USB sometimes gets to little power?

Thanks in advance for your help! :-)

P.S.: Its hard to test anything like "pull out all other USB-devices and see if the problem comes up" cause like I said: sometimes this problem doesnt show up for weeks!

First off, something to know is that USB devices are powered off the +5V standby rail (+5VSB), which is completely separate from the rest of the PSU. It's like a small PSU inside the main PSU, which delivers power even when the computer is turned off.

Your PSU is more than adequate for your system and might even handle Crossfire. However, it is *theoretically* possible that the +5VSB rail may be faulty.

However, this problem is more likely caused by the motherboard, that being the other thing to have a major affect on USB devices aside from the devices themselves.

Or it could be a driver issue. See if the problem occurs when running a Linux distribution (you can run Linux off a CD without installing it, I can help you with that if you need it).

Thanks a lot for your quick answer! :-)

If I run a Linux distribution the problem maybe wont show up for some days... but then suddenly its there!

Think I will get everything ready for using Linux and as soon as the problem is there I will boot Linux and see if its still there. Afterwards I boot Windows and see if its there.

Okay, thats the way...

Thanks again! Will do some "googling" on Linux now! Maybe Ill get back to your offer then! ;-)

I finally found the problem!

It was the wLan-Router standing between my comp and the mouse.

Thanks again for your help! :-)
