It all started some days ago, well, after I removed some Windows Services accidentally, but then I renabled all I needed again. Very often, while using the computer, the bottom bar the taskbar freezes completely. I mean, I cannot click the start button, nor the tabs of any program. I can however, switch programs using Alt+Tab and open task manager. if I kill explorer.exe, then open it again everything seems fine (but usually it takes a lot for the taskbar to return). The taskbar freezes normally for 10-15 minutes, and that's horrible. I have run a scan with all the softwares in my sig, but found nothing... Normally my PC is a bit slow (30GB out of 80GB HDD remaining), but this has NEVER happened before... I wonder if anyone could help?
