Can not copy anything and screen freezes
                                                
                                                
                                                
                                                
                                            
                                                                                
	I am not able to copy anything, also not able to take a screenshot. Screen freezes and system got to hang for a long time.
	But if I log in as different user I can do whatever I want.
	My account has all administrative privileges.
	Please tell me if anyone has this problem before. I got the reason why windows was not copying anything.. Cause I had changed ram setting msconfig. So system has sufficient RAM to boot and play thing but was not able to do any memory related task, like Prt Scr, copy.
