My HiGrade computer has writen 99999999999999999 on boot up since I received it. If for instance I opened an Excel file after boot up the computer automatically starts writing 999999999 and doesnt stop until I press a key. If I then close the Excel file the problem ceases. The 99999999999s are also written if say I want to log on to my AOL internet connection. The 9999999999999 appear (as asterisks) where the cursor appears for me to type in my password. The computer also makes a ticking noise on boot up when it is waiting for me to take an action. I use my computer without any problems after I have stopped the 9999999999999 writing.
I'm amazed at the response and so quick - never used a helproom before but this is brilliant.I am using Microsoft Millenium on my computer. Have tested to see if the 9 is sticking but it is OK. Am trying the plug - unplug keyboard solution. Why dint I thnk of that.
