That's pretty light weight and if you've done your research you know about how Electrolytic capacitors work. In short, they work a little better after warmup.
I'd take this up with its maker as the rather low PSU can stress other parts and age them quickly. That is the motherboard's own power system has to work harder and the aging is going to take its toll. This was not a good build in my opinion and its maker/designer should be held accountable.
So I had this windows 7 computer half a year, when I decided to switch to windows 8. Immediately after I switched to windows 8 the computer crashed when I started it. After it crashes it restarts, and everything works fine. I upgraded my computer with more RAM and the computer didn't crash. But the second time I started it, it crashed again. In the event viewer you can see the error.
It is critical, has the ID 41 and the source is "Kernel-Power".
