Cursor Jumps all over screen

I don't know what I did but I haven't had an issue since last postings. I believe I might of uninstalled then installed..can't remember. I might of run malware,anti virus programs too. Plus other stuff off the web after Googleing about it.

I have an HP TouchSmart 520 PC that is having a problem with the cursor jumping all over the place while I am either typing or browsing, or doing nothing at all. Or it will minimise open windows/programs to the taskbar, open the clock in the bottom right hand corner or disappear to the right of the screen. It does this with both a wireless and wired mouse, and when there is no mouse connected at all. I have attempted to update all of the drivers, using driverupdate and even driver genius, but it still happens.
As this is not a laptop, there is no touchpad to accidently touch.

Any ideas?

Is anyone reading this post? Thought I would have had a reply by now! Same problem still existing, giving me the shits.

I've had the same problem for ages. EXTREMELY frustrating. And actually costing me money. I play a bit of online poker, and on one of the well known sites, when you are playing in a hand there is a tick box option to 'fast fold to any bet'. On occasions when i am about to take a big pot, but just before the other guy comes in with a final bet, guess where the cursor jumps to? Bam, the cursor has hit that button and 'folded' for me automatically, tossing away a winning hand, and a bunch of cash that should have been mine, in the process.

Sometimes the cursor seems to jump pretty randomly, sometimes it seems to be particularly 'drawn' to such tick boxes (total randmomness would mean it would hit these far less frequently than it does). I also get the same stuff everyone else has described re web browsing, word processing, etc. Frequently if i'm trying to read a web page, the cursor will jump to bottom right of vertical scroll bar and 'hit' it fast multiple times so i get zoomed way down to the bottom of the page. I manually scroll it back up and *try* to start reading again, and it just repeats.

Seems to be very little rhyme nor reason to when it misbehaves, however. Writing this just now, for example, it's doing nothing. I bought my laptop (a dell XPS L702X running windows 7 64bit) around April 2012, and for a good while this problem did not exist. It seemed to just start gradually, can't remember quite when exactly. When the free macafee anti-virus that came with the machine ran out, i uninstalled it and downloaded free avast instead. That seemed to stop it, or lessen it for a while for some reason, but gradually it has returned again.

I don't do a lot of 'work' - typing etc - on this laptop at present, so have kind of ignored the problem, but now it's starting to cost me money on poker tables, i have GOT to find a solution to this before i pull all of my hair out in sheer fury and frustration. As others have said, i am sure it is not a touchpad sensitivity issue, as my cursor can jump about when i'm not even touching the laptop. Unless there is any crap that has got in there and is somehow affecting it internally. But i'm not very techy, and would be pretty nervous about trying to open my machine up and clean it out, as someone else suggested. Likewise not to sure exactly how to go about trying to implement some of the suggested solutions on here, but i will have a go and post back on any findings/progress.

You managed to find a fix yet, oopsmx? Maybe this thread has kinda died a death now...

Sorry, rather a long and rambling post, haha.

Many thanks for your response, Andrew. However, that option already is unchecked. This is just random cursor jumping, as described throughout this thread - although, as I already stated, it does seem not to be entirely random, as the cursor can seem to be particularly 'attracted' to buttons etc when it jumps.

Also, I don't have a mouse, I use the touch pad. That is probably the first thing I'm going to try, to get a mouse and disable the touchpad - though again, others elsewhere on this thread have said that that has not necessarily fixed it. But I will try it and repost. (On which note, any advice on best brand/models of wireless mice appreciated - though maybe I should enquire about that in a new thread...)

Had to completely reinstall my Samsung RV510 this year with W7HP-64bit SP1 DVD and had exactly this manifest keyboard problem. eg Random leaping cursor movement etc -

Z3r010 - thank you - upon reading your comment about touchpad drivers went to Samsung site and found at Drivers section WINDOWS 7(32BIT,64BIT), 87.91 MB, ZIP, MULTI LANGUAGE VERSION : 1.1.0.0 18 AUG, 2010 at NP-RV510I (NP-RV510-A05UK) | Support | SAMSUNG UK. Reboot and OK.

NB don't even use the touchpad on this box - use USB mouse - Have recently seen this solution logged on others sites as well.

Often one must install the OEM touchpad software even to use a notebook mouse. This is because there is a setting to disable the touchpad which will then appear on a tab in the Control Panel>Mouse for your specific touchpad maker to prevent the phenom of "palm drag" that causes the cursor to jump around.

Otherwise without a notebook mouse palm drag is also resolved by turning down the touchpad sensitivity until it stops as Rich discussed 3 years earlier.
