Ok so i've got a very odd problem which is baffling me. I'll just post what I've posted on tech help forums.
I have a very strange problem which I've no idea how to solve. I turned on my PC yesterday to find that my USB mouse wouldn't let me left-click as it thinks it's constantly pressed already. Moving the pointer around the desktop shows the blue selection box as if I'm clicking and dragging even when I'm not. It then randomly creates a new selection box as if the left button was unpressed for a moment.
I checked the connection and tried it in 2 other USB ports and had the same problem so i uninstalled the drivers and rebooted but this didn't solve the problem.
So next i took out the mouse thinking it must be broke (even though it's only a few months old) and put in an old mouse with a serial connection only to find that this is having almost the same issue also. The difference is this one doesn't think it's left button is in-pressed always. It acts normally then randomly every few seconds it acts like it's just been clicked.
I did a virus scan and found one, got rid of it but this didn't help the problem (and I've no guarantee this virus was even related to the mouse problem) and i did a system restore. NOTHING HAS WORKED.
My biggest annoyance is i literally don't know what could be causing this. I use my computer daily to earn a living so please someone help as i need to fix this ASAP!
