After downloading Iolo Technologies 'System Mechanic' V11. (Previously ran Sys. Mech. V10) I cleaned up the Registry, updated drivers, de-fragmented memory and hard disks. Everything appeared to run successfully. No errors or warnings from System Mech.
Attempted to use my printer (Epson SX215) after. Immediately froze the system i.e. locked out unable to do anything. Checked printer driver and tried load of driver from Epson site. Reported I had latest driver. Used Control Panel and 'System' icon to check drivers. Reported drivers running O K.
Iolo Tech. suggested running 'SafetyNet'function to roll back Registry and driver updates. Did this; no change in symptoms. Used digital camera as additional device to check USB ports. Same result i.e. sys locked up when camera activated to upload pictures.
Should also explain stupid brain failure and not previously dealing with a Windows (XP) startup warning after using Sys. Mech V10 some time ago to remove unused startup programs ?? if my memory is correct). Warning msg. at startup as follows (verbatim as warning msg. appears): keyhook.exe - Entry Point Not Found The procedure entry point [email protected]@@[email protected]@[email protected] could not be located in the dynamic link librarySiSBase.dll.
This msg still appears on screen at startup time when startup has completed.
Have used Sys. Mech. to see what it reported as I wrote this topic, to see what it said. Reported registry errors, fragmented memory and disk files. Also disk errors so did a repair on 'C' and my other 'F' hard drive. Said it found no errors.
Have run out of brain cells to attempt fix myself.
Is this likely to need a full 'Windows Repair' job or less drastic fix e.g. repair of USB interface ports driver(s)/ other?
