Windows 7: app windows not refreshing

When I drag/move Win Explorer window it leaves a trail of black rectangles until dragging stops.
Is also happening with portable text reader Metapad.

"Printscreen" does not capture problem.

Would appreciate any help, thank you

It could be the monitor going bad. Any other problems in full screen mode? Like games or youtube?
You could try a simple diagnostic test for video...

Go into Mouse Properties and look if you have Display Pointer Trails checked.

Thank you andrew129260 for your response.

How would I do a "simple diagnostic test for video" ?

Hi Layback Bear

Mouse pointer settings are:-
[ ] Enable pointe shadow
[ ] Display pointer trails
[x] Disable internal pointing device when external USB pointing device is attached
- was "False" now "True"
- screenupdating has got worse.
----
Am using a wireless mouse + keyboard
[ ] Disable internal pointing device when external USB pointing device is attached
- disconnected both -- only using laptop keyboard and mouse-pad
- problem persists
-----
Screen updating is lagging. ie, when I drag any small window over another the "other" is slow to refresh.
I think it is getting worse.
Toshiba is 14 months old. I didn't take it out of the box until 8 months ago.

Would appreciate any help.

You didn't answer my questions....

1.) Any other problems in full screen mode?
Like games or youtube?

2.) Google How to Test a Video Graphics Card | eHow

Here is one article with some tools you can try. You can also try using Toshiba website to see if they have a diagnostic tool for their brand. Even though this is asus, you could use their video tests, wouldn't harm anything:

If any weird lines appear, or your computer restarts, you have a problem.

• No gamers -- Toshiba is a business PC. For web browsing, emails and SMS send/receive only.
  And a regular user of sevenforums.com
• All users are prehistoric. Past use-by-date.
• youtube in full screen and normal is OK.
• Most data is allocated to an external HDD
• Both cold boot and reboot are perfect -- no video problems that I can see

Toshiba was a factory rebuild -- one dead pixel from day one.
Laptop has been getting slow start and shutdown/reboot in about the last 6 weeks.
Defragged system files (MyDefrag) -- took two hours !!
I have been too busy to even think of defrag
Ran out of patience to defrag the little bit of data in "C:\"
Reboot

... problem fixed.
===========
EDIT 1-Oct-2013 18:06 hrs (local time)
TOO EARLY to celebrate -- not fixed
===========
I will follow up both your "video test" suggestions, because I am on a mission ... to manage my own PCs.
Will report back here with results tomorrow.

I do appreciate your support, thank you

Result:= OK no problems detected

I have googled for Toshiba graphics card tester, but all finds were pre Win-7 -- too old.
One find was way over my head, for serious gamers. It envolved downloading a game.

I treat my PCs like a mistress, keep her happy without pushing my luck


Have discovered "Metapad" I have been using since 1999 and its later incarnations might be the culprit.
Metapad is portable but I have file associations directed to "Metapad 3.5 LE"
For about 3 years Metapad 3.6 was beta. Just discovered it is now elevated to a "go-er"
Ran Metapad 3.6 last night (as portable) ran a treat, until I ran 3.5 LE.
3.5 and 3.6 share same registry key. Am about to remove 3.5 and clean the registry etc, and start with a clean slate.

Look after my girlfriend while I am away !

This Toshiba laptop is starting to concern me
Fan is running most of the time. Dual core temperatures are reading as approx 40° C when the PC is idle.
CPU temp hits app 60°C during active YouTube streams.

I have noticed some portable programs (located on the laptops C drive) are leaving a trail of white or black filled rectangle as the program's-window is dragged.
1. Metapad 3.5 LE
2. System Spec 3.06

Occasionally Win-Explorer leaves the same "trail" ... lagging screen refresh ... but not all the time

I have installed "CoreTemp" app and set the "alarm" temperature as 60° C
With very little knowledge ... is my 60°C alarm setting too low? Am I being paranoid ?

The screen refresh lag is really a worry, because if this Toshiba laptop falls over I don't have any other internet access.

I have found some tutorials How to clean a Toshiba Satellite ... with one particular ...
How to Clean Dusty Fan in a Toshiba Satellite Laptop (Part 1)
... a mammoth job to strip down the Toshiba Satellite, just to clean the fan and CPU(?)
Like removing the engine of a car to empty the ash-tray.

Would appreciate any help

You could look at something basic that might be putting a strain on your computer making things lag.

msconfig/Start up.
Give us a a picture please.
