I'm running Windows XP SP3 and am having problems with different Windows or Office programs displaying the "Not Responding" message. Excel, Word, Outlook email, and must recently, My Computer and a 3rd party application from Cerner Corporation (Pharmacy app). Task Manager will not kill the apps and eventually taskbar and all Desktop icons disappear.
Usually, I can get into Task Manager to close all other programs except those that are not responding and restart. Other times, either I cannot get to Task Manager or get BSOD during shutdown and have to power off the PC to reboot.
Most recently today, I got an UNS.exe -Application error message.. Instruction at "0x7c809823" referenced memory at "0x01299648". The memory could not be "written".
Is this a hard disc error meaning that my hard disc needs to be replaced or there other remedies?
Thanks
