Hmm. Unusual problem for sure. It feels like a RAM issue. Aiko shouldn't cause this, unless you've selected an extraordinarily high dpi render setting, or there's a physical problem with your RAM. I use a free little app called RamIdle (use Google to find a copy). It not only monitors what spare RAM capacity I have, but also clears unneeded RAM as I go along. Dunno if you've got something similar under that censored part next to your clock. There are several apps for testing your RAM. There is a little app called Aida32 (Google again) that is brilliant for testing and identifying stuff like that. If you have two RAM chips, for instance, but one of them is failing or has the wrong clock speed, or isn't seated properly or sommat, it'll spot it. Task Manager is just a basic Windows utility, accessed from the Ctrl+Alt+Del panel (in most versions of Windows). Open it and click on Processes, then click once (sometimes twice) on the 'CPU' sub-heading. That tells you what is using your cpu. Good luck.
