Just received a Diamond Radeon x1650 pro and a coolmax 450 watt power supply to run it, was upgrading from an x700 pro and the stock 300 watt psu my emachines T6212 came with.
Opened up the pc case, disconnected the power, then the cables, and installed the new power supply. Tried booting the pc to make sure that everything was functioning before putting in the new graphics card, and the problems started.
The harddrive clicks, the fans spin, the light on the front of the pc goes on, but it will only boot to a screen with the Emachines company logo and 'press f2 for boot menu' and 'F10 for bios'. After going to this screen, the boot process stops. This takes about... a quarter of a second from when the power is turned on.
Sadly, neither of those two options work- that is, pressing f2 or f10 for any amount of time hasn't any effect.
I have tested the harddrive in another pc, and it's fine. When I disconnect the harddrive from the machine and boot it up, it does the same thing it would if the hard drive were connected. Given that, I assume that either the motherboard or the processor are fried- I have no way to trouble shoot either option and am open to speculation.
The most irritating part of my birthday present woes is that when I reinstalled the old power supply, the same problem persisted.
And happy new years.
