I'll be surprised if anyone has an idea of this problem.

So i bought this new intel dual core computer. Everything is new except the LCD monitor. Sometimes my monitor goes blank for a second and then come up. I figured this was because of the loosen power cord. So whenever i tried to tighten that up and when the display returned the mouse would stop working. Everything is fine.. keyboard.. and all. System is working well. No errors on eventvwr. The mouse would not even work if i reboot the system. So i have to plug the usb back in. WTH Power cord has anything to do with mouse? I changed the cable.. and used the converter for mouse to plug it in PS2. Monitor doesn't go blank as the cable is tightly fit. if i try to plug back in mouse doesn't freeze now.

So could it be the VGA cable?
Motherboard? (It's brand new)

and yes i changed the mouse before too.. that mouse did not freeze but the arrow was lagging and moving slowly.

You've got me confused on this... you are not clear as to how you are plugging in the mouse to begin with.

I'm guessing that you are using a USB mouse and that the problem occurs when your screen flickers/refreshes. When the screen snaps back in and displays output, the mouse pointer stops responding on screen and you are unable to recover the mouse functionality.

Is it an optical (laser) mouse or a mechanical mouse?
Are you plugging mouse into USB ports on the monitor or are you plugging into USB ports on the tower / motherboard?
Does the mouse only function properly when you use the PS/2 dongle rather than plug the mouse into the USB ports?

PS/2 is really not the preferred connection to use nowadays, but if that is the only way that you can keep the mouse functioning normally, i guess that is the way to go. I've seen more instances of mouse function ceasing or even keyboard function ceasing when connected via PS/2.

If your monitor has USB ports on it i could see that might spike power through the monitor or perhaps be unable to push out enough power and cause a USB mouse to cease functioning. Dell monitors equipped with USB ports tend to be glitchy when you plug in a USB flash drive or other USB device on the monitor.

Ninja, Thanks for replying and i'm sorry english is not my first language. I will try to be more specific. When the screen goes blank by itself. Then there's no problem. But if i adjust the power cord myself.. (Put back in) Then the mouse stops working.

To answer your questions:

It's an Optical Mouse
USB ports on the motherboard

As i have said.. Mouse works well on usb ports as well. It's just when i try to tighten the power cable.. the mouse stops working. But if you do that while the mouse is connected to PS/2 then there's no problem.

Sure i have changed the cable which is tight enough and i wont need to do it by myself anymore. BUT I just wanted to know what are the causes of that problem?

I guess I'm not understanding why you do anything with the power cable...and what power cable might that be (from where to where)?

Thanks.

It's definitely an odd problem.

But i think with the monitor's power cable secured tightly, you have probably resolved this one.

Have you set the resolution and refresh rate for the monitor?

I don't think you need to set refresh rate for LCDs. I have it on 60. But it doesn't matter.

Resolution to: 1024x768

Ninja, But the problem is not normal right? And really doesn't make any sense. I would be happy if i know the cause and solve it. Do you think it could be VGA cable? Because of EMI?
