When I try to resume my computer from standby the fans spin up to 100% and the drives spin up as well but all the peripherals are dead. The power light doesn't come on either. The have to hold the power button to turn it off. Occasionally it will do this on a cold boot too. It began doing this intermittently about a month ago but now it does it every time.

Oh sorry, forgot to say I tested the voltages on the PSU while it was in that state and everything seemed fine. The OS is Kubuntu but I tested it with a live cd of an older version of Ubuntu and it does the same thing. The computer is an LX6810 (specs)
