Why does my mouse and keyboard etc "slow down"?

Avoriaz

Hi, I have a Windows7 Acer laptop. I have used it for over three years with the supplied 500gb hard drive and a wireless Logitech mouse. It has been very satisfactory.

I recently bought a 125gb SSD (SAN brand), installed Windows7 and everything else from scratch.

It worked like a dream. It loads Windows7 and apps far faster than before.

However I am now finding that, after the laptop has been switched on for a while, the mouse is getting slower and slower to react. At first the laptop will respond instantly to any mouse press but, after some minutes, it gets slower and slower, sometimes taking several seconds to react.

It is also happening with the keyboard. Sometimes it will act normally and enter each character as I type it but it then starts stalling or freezing and then suddenly displaying the string of characters I have carried on typing.

Each character should smoothly appear as I press the key not sometimes jerkily in a string a second or two after I have pressed the keys.

I also notice it when playing backgammon. Instead of smooth movement of the pieces, they start moving jerkily.

The up, down, left and right arrow keys are also affected.

Right clicking in Firefox 23.0.1 to open up new tabs etc is also sometime slow and jerky.

The scroll wheel is also affected.

The problem goes away for a while every time I restart the laptop but it always comes back again after ten or fifteen minutes. I see no sign of any overheating.

At first I suspected the mouse but a different wireless mouse made no difference.

I then reinstalled the drivers. Again no difference.

I then put the old 500gb disk back in. The laptop returned to normal perfect operation with both the Logitech mouse and my other wireless mouse. I used it many times over several days and the problem never once occurred.

After a few days I put the SSD back in and the problem has returned.

What should be my next step in identifying and correcting this problem?

I don't think I have a virus. I have Avast anti virus, Windows Firewall on the SSD. I haven't yet installed the anti malware I have on the 500gb disk. Might a keylogger or something like that be slowing things up?

Could the SAN SSD be causing this problem? I don't see how. It loads Windows and apps very quickly and I haven't had any data issues.

Thanks

How much free disk space do you have on the SSD? How did you configure it? Is the windows software on it up to date, or is it from a DVD so it's trying to download & install lots of updates

86 gb free.

There is one volume on the disk. I didn't create any partitions.

Windows7 is fully up to date.

I installed Windows7 from the same DVD I used for the 500gb disk. I didn't "configure it" other than to choose my preferred appearance, font sizes etc.

I'm using an Acer, and they come as stock with a 3 way split partitioned hdisk, so the OP is confused?

One partition is the recovery, the 2nd is the OS, and 3rd is data.

So you have filled the C: drive, where the OS lives; need to use , as data; and setup swapfile manually to utilise the spare memory from drive

If you have a usb mem stick, use it for 'speedboost' option on windows..

OK, unless the DVD is one you created in the last few days then sorry, it's not up to date. After it has been installed on the new drive then it will download all the updates required to get it up to date.
If your DVD is a few years old then the system will need to download service pack 1 and all the updates after that. That's a few GB of data.

Next, on the configuring, I wasn't talking about Windows, but the BIOS. The hardware needs to know that it's now booting a 128GB drive, not a 500GB one.

Thanks but I am not confused.

As stated in the OP, I am not using the original disk. I have bought a new disk.

Thanks but I know all that. SP1 and all the other updates have been installed. As is normal after installation, Windows7 checks online for all updates and installs them.

My Windows7 is fully up to date.

The BIOS is showing the correct information for the SAN SSD disk.

I am not aware of any specific actions needing to be taken when installing Windows7 on a new disk on my laptop.

Windows7 should recognise that it is being installed on an SSD disk and configure itself accordingly. It would appear that it has done so.
