Error code=2147023174"/ "System Restore is not able to protect your computer"/ "Error using COM/OLE occurs"/ "Error- Out of memory". I cannot open Windows Media Player. I cannot sign into MSN PREMIUM even though DSL is functional and connected. Multiple desktop shortcuts will not open. Extremely slow boot with error message: "Windows cannot open file: file 4.exe…."
