    Lately my computer has been just making a solid tone when I turn it on, instead of posting, and will not boot. If I unplug from the wall for a few days then it works again for a few days. I was getting errors saying the vid card was not getting enough power. So, I swapped out the 650 PS for an Antec Blue Trupower 750w. The BIOS says the 12v is getting 11.8 volts, but PC Wizard 2010 says the 12v is only getting 1.5 volts or so. This is with the HD fan plugged in and running. Without the HD fan plugged in, PC Wiz said the 12v was getting 11 volts. Could the HD fan really be sucking that much power, and shouldn't 750watts be enough?

    I've had server power supplys completely fail because of bad connections to hard drive trays. I can't say that it is definitely the fan, but I would say if you have an extra fan laying around trying swapping the fan. Maybe even try just swapping the connector the fan is attached to (if you have another available connector coming off your PS). If some short in the fan or that specific PS connector is feeding back into the PS it can cause all sorts of problems including causing the PS to fail.

    Hope that helps.
