My computer tends to freez for a few seconds. It just happens. It also freezes on boot. It hangs on "pleas wait" for 30-60 seconds. Also, when I get to my desktop, it also freezes. That happens on boot every time, and it freeezes randomly while running (weather I'm gaming, watching a movie, browsing...) This started to happen when I got a new PSU. The PSU is OK, but the old one could have damadged the capacitors, although I can't see any that are blowed. Any help?
