hi This morning when i switched the pc on it started to open and then just as it reached the stage of loading you settings it froze and i had to switch off and when i restart nothing happens i have tried this a few times. This happened in may and i changed the power supply and it has been working ok.Is this power supply problem again? Last one was a new one. Is there any way to check power supply? and help advise will be appreciated. Thanking in advance
