Just recently my PC seems to be running like a broken poofter. I click on something, sometimes nothing happens & I have to click again & sometimes again. The Internet seems a little laggy yet when I try an online speed check my broadband speed seems fine. After boot up things are very slow to warm up & get going. It's working fine I'm sure but the whole experience seems just a little 'sticky' of late. I've tried the usual things - defrag HD, virus/trojan scans etc. There doesn't seem to be any major problems that I can see. Perfmon shows thnigs quite settled although the page file does seem to spike horribly whenever I do anything. Not sure if this is normal or not. I'm just wondering what else to try.

But this problem is weird. It's not like anything is seriously wrong. Not even noticeably wrong. It's just that you click on something & it hangs. So you click again & it's sweet. Weird problem.
