A while back this problem started, but lately it seems to be getting worse and worse. I feel like I should probably ask about it now before it gets more out of hand.

My mouse cursor has been glitchy. I mean, really glitchy. I've done a Google search on "jittery mouse pointer" and such, but I haven't found any really useful information (much of it involved video drivers and refresh rate issues).

I believe this problem is completely separate from anything having to do with video. As far as I can tell, there's something wrong with either my computer or my mouse socket (sorry for the bad terminology).

During the course of perfectly normal use, like surfing the web, using editing software and gaming, it's as if the computer receives false messages from the mouse and interprets these messages as either movements or clicks.

To explain it simply, I find that the cursor is frequently jumping, freezing, or clicking apparently of its own free will. I'll explain the three things it does below: 1) I'll be moving it around and then it will stop completely--sometimes it's just for a few seconds, but other times I have to fiddle with the mouse plug or refresh the computer (put it into standby then wake it back up). 2) It clicks "on its own." Again, I'm not sure how this happens, but it does. I can just be moving the cursor around, and then suddenly it's clicked, selected something, or pressed a button by itself (occasionally at the worst possible moment). 3) After a certain period of normal operation it jumps around the screen randomly, sometimes after a moment of freezing. In more rare circumstances, I move the mouse and my cursor will actually begin to fly all the way across the screen repeatedly, clicking on things at will (it's grown especially fond of opening and closing the Start menu over and over again). Imagine the cursor moving so fast that it goes instantaneously from one edge of the screen to the other. Now imagine that happening maybe 20 times a second (NO exaggeration) and you've pretty much got the picture.

So I hope I didn't go too long-winded. I wanted to be as thorough as possible, since it seems to be an odd case and I wanted to make sure I gave you the most detailed symptoms I could. But it would be greatly appreciated if somebody had a solution or treatment for this problem, since it's already going out of control (during the course of typing this message I've had to copy my text three times just because the mouse has been pressing the "back" button and nearly deleting my entries on websites). As soon as this issue has been resolved, the better.

NOTE: I've tried plugging in a ball mouse and using it. The same glitches still occur. This is what leads me to believe it is not a mouse problem.

Sorry for the double-post, but Filefront does not allow edits past 30 minutes.

So your mouse is acting up, and it's not the mouse itself...

Some information about your computer would help. Is this a pre-built system or custom setup, what version of Windows and are you using a USB or PS/2 mouse?

Basic aspects of my computer:

-Some sort of Athlon AMD processor (2.2 GHz) -2 GB DDR RAM -nVidia GeForce 7600 (512 MB) -about 200 GB hard drive -19" monitor, 1280x1024 max res. and 72 Hz max refresh rate -Bought this system from a retailer, but the video card and RAM I bought and installed myself.

I'm almost certain the mouse is PS/2. In case it matters at all, it's of the "nSpire" brand and is a laser mouse with a cord.

Hmm. That looks like a pretty solid build. What version of Windows is that on (XP, Vista, etc. , 32 or 64 bit)?

If you're not sure if it's USB or PS/2, here's a couple of pictures to give you an idea. Look at the plug that it goes into.

PS/2 looks like this:

USB looks like this:

Did this mouse issue just start happening at random, or did it start after you changed anything significant (installed new hardware or software)?

I'm running Windows XP, and since I'm pretty sure the 64-bit versions get labeled "x64" or something, I think it's 32-bit.

Yep, that's exactly what my socket looks like. I have a PS/2 mouse.

Well, the only two pieces of hardware I've really installed in this computer are the RAM and video card...I know that the mouse starting having trouble before I installed the RAM (which I did about a week and a half ago). I also know that it happened long after I put in the new video card. As for software, I have no idea. I wouldn't have known to pay attention for that at the time, and by this time I can't even recall when the mouse issues began.

I've been reading the magazine Popular Science for a while now, and just recently I learned from it that a laser/optical mouse operates by repeatedly reading the shadows it casts across the surface grain of whatever it's moving across. I also just read on some site that monochromatic mousepads (particularly black ones) work the best.

Now, my mouse pad is far from monochromatic; it's a picture of a dog and it has many lines on it of varying colors. The mouse started having problems long after I got this mousepad, but perhaps something like this could be the problem? Could it even be something as simple as a dirty mousepad? That wouldn't even come close to explaining the errant clicking, but maybe it's something to consider.

The surface that your mouse is tracking on could affect how it performs, it's true.

Try rolling the mouse over a few different surfaces. A monochromatic mouse pad, or even just a solid color notebook cover, to name a few. See if it has any effect on the mouse's movement.

Hmm. Well, I took the pad away and I'm running the mouse across the surface of my computer desk, which is wood and has very prominent grain. The mouse movement is extremely improved...the cursor doesn't halt as much/at all anymore. It does still jump around, but I've developed a theory that the jumping and errant clicking are due to the mouse and the halting was attributed to a bad/dirty mousepad.

That could be the case. I've never heard of the "nSpire" brand, which leads me to think they're something of an off-brand. If you want a really good, inexpensive optical mouse, try the Microsoft IntelliMouse Explorer 3.0. It's wired, optical, and has 5 buttons. I used it for years before I bought my Logitech G9, and it's still in mint condition.

All right, thanks for the recommendation. I just thought of another symptom, though. It's something small, but it might mean something: sometimes when the mouse freezes, the three "num lock," "caps lock," and "scroll lock" lights all turn on and then off simultaneously. After they do this, the cursor can move again (perhaps after jumping a short distance). After the three lights come off, "num lock" is off (I normally have it on).

Might that mean anything?
