Ok, so I have had the machine in my sig for around 2 years or so, but recently something is happening that I can't correct. When I hit the power on button on the front of my case, the fans power up but the machine fails to boot. It will stay like this ,...with all fans running until I hit the small reset button on the front of the case (sometimes takes several attempts) then the Bios splash screen appears and the system boots into Windows as it should. I have cleared the CMOS (battery removal, removal of main power cables - power down for 30 minutes) but it still does it. Anyone got any advice as to what I can check? It is getting rather annoying now.... help appreciated. Cheers in advance.
