Click the Windows "Start" button or press the "Windows" key. The "Start" menu opens. Type "Cursor blink" in the "Search programs and file" text box. A list opens. Click "Change Cursor Blink Rate."

The hard drive has issues, or the window files are corrupt. I suggest a computer repair store to retrieve files and test hardware.

Use another computer and go to this WEB site for assistance.

Remove the battery and open the case. Look inside the computer with a flashlight to see if any of the capacitors are busted or leaking from corrosion. The capacitors look like little battery towers, but they are not as tall as the AA or AAA batteries.

If the capacitors are bad, your computer goes bunkers.

Bring your mouse cursor down to the bottom right of the monitor screen. Click on the blue circle with the white arrow in it to reveal your system tray icons. Right-click on the Volume icon. Looks like a speaker. Click on Adjust Volume Properties.

This can happen when there is two problems.. One the computer might have been affected by virus.. Or the other thing might be the OS corrupted.. Try to get into safe mode and check if the system is working fine.. If it works well there try to do a system restore to a place wr it was working well.. If in safe mode also it doesnt work well then go ahead and reinstall the OS...

hold down the menu button for 20 seconds until the lock symbol turns into an unlock symbol.

You will find under window graphic controls you can no longer Print screen like when we used the LPT-1 ports.
so a work around is to copy and paste to word, word pad, publisher, almost anything that has a cursor blinking.

any way here goes, select (highlight) the area you want to print and if you want the whole page under edit click on select all....then put you arrow (cursor) on the blue part, right click and choose copy.
then open word, word pad and right click again and choose paste. then send that page to the ole printer...and viola...you done did dodit....
Hope this works for you my friend, good luck, please leave rating. thank you kindly
