Error Reporting is simply Windows letting you know that it is having a problem with a program, or a program's compatibility with your hardware. What you can do (as a minor fix) is to disable the System Restore, and do a Windows update. (www.windowsupdate.microsoft.com, and tell it to scan your computer.) Also, you will need to go to your PC manufacturer's support website (i.e. www.gateway.com/support) and download all driver updates and install them. Do you have a/n current, updated antivirus program on your PC? If not, you will need to buy one (Do NOT buy anything from Symantec/Norton... it's a lousy program.) If you need a free antivirus, you can download AVG antivirus (www.free.grisoft.com/doc/1)
As a last resort, ( and a bit extreme) you may have to format and reinstall your hard disk, but from what I see it hasn't gotten that far yet.
Hope this helps.
