......and have no malware apparant on my pc. The user who helped me out, Essexboy, has advised me to post in this thread as the problem appears to be hardware and not any kind of malware.
brief summary of what has happened:
* I cannot click the active window in whatever program i am running. I can see the window and everything looks normal but i cannot click on it at all. It happens on every program i run and at random times. i temporalily solve it by presseing Ctrl+Alt+Del and closing the task manager window
* PC just crashes for no apparant reason at startup and at times, during normal use. It is then a struggle to reset the pc to start-up fully again and requires several attempts to startup.
* Variuos hijackThis and spyware searches have been carried out ( see original post for details ) and no malware is apparant on my PC
Any help here will be greatly appreciated
