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 :)

Tried How to Test a Video Graphics Card | eHow
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.
