be having the issue well over a week. Is Windows 7 . . . - x86 (32-bit) or x64 ?
64 bit - the original installed OS on the system?
Vista home premium - an OEM or full retail version?
OEM then installed win 7 retail - What is the age of system (hardware)?
3 years - What is the age of OS installation (have you re-installed the OS?) 2 years
