I'm not quite sure how long I've had this problem, as I don't often have to use Task Manager. But I've found myself unable to activate the program at all, using any of the shortcuts. I might be worrying over nothing, but I have heard this sort of thing is an under-handed and dirty trick used by some viruses and malware. I scanned my PC with AVG and Spybot-SD, with no luck. But to be honest, I'm none too sure about this sort of thing. I've also been through the 8 steps to get the ball rolling, as suggested. No luck so far though, Task Manager still won't activate. Hopefully one of you gents will be able to make something of these logs that the guide requests I post, though. If there is anything I should be doing to keep my PC safe from this sort of nonsense that I'm not doing, please don't think you're being rude by pointing out any silly mistakes I've made. You'd be doing me a grand favour. My thanks in advance.
