Hi,
After using and shutting down my 2008 HP Pavillion computer perfectly normally it now will not start correctly and no input signal is being received by the monitor. There are no beeps from the bios to give any clues to the problem. The lights all come on when the power button is pressed, all the fans spin, disc drives will open and close (they also make a sound like they are trying to read a disc when the computer is switched on), USB ports work as it started charging my mp3 player the first time. The monitor definitely works too.
So far I've tried cleaning and re-seating everything which made no difference, I've tried running the computer on the bare minimum hardware and resetting the bios by replacing the battery and that's not helped. I tried starting it with the RAM removed and that caused the bios to beep so I don't think there is a problem with the motherboard (cpu heatsink also gets hot so cpu seems to be doing something).
The two things I think could be the problem are the power supply not giving the correct voltage or the graphics card dying (though the fan on it spins).
I've got a power supply tester on the way, does anyone else have any ideas what could be the issue?
Thanks.
