hi guys.

when switched on, my desktop (win 7 32bit) just shows a blank screen apart from the message that its running in low power mode, no boot screens, bios options etc.

if i unplug the monitor, it says that there is no connection.

i tried the monitor on another pc and its ok.
i then replaced the graphics card with the original and it still gives the same message.

when powered, the fan on the PSU is working, also the fan on the CPU (i3) is working.

any ideas on the problem?

no onboard graphics.

32bit win 7
8gig ram (was going to put 64bit os on)
radeon hd5770 (from overclockers)
corsair cx430 (from overclockers)
dvd and 500mb hd through sata connections.

the card only has dvi.
but my original card has dvi/vga and that gives the "low power mode" message on both inputs as well.

EDIT: no onboard vga/dvi/hdmi ports.

i did try another, the other card has vga/dvi ports and it says "running in lo power mode" on both ports.
