I'm running a cheapish home built PC with Ubuntu on it as my main work box. A week ago when I booted it up the monitor wouldn't come out of standby (blank screen with flashing 'power on' light.) I'm coming to the conclusion that it's a motherboard problem but before I shell out on a new one I wanted to check if there's something else it could be.
Monitor and VGA cable work fine when plugged into another PC.
As soon as I unplug the video cable from the PC the 'A cable may be disconnected' warning pops up, so the monitor knows there is something on the other end when it's plugged in.
I've tried a new graphics card and still get exactly the same problem.
None of the on screen monitor adjustment settings appear when I push the monitor buttons.
Cannot get into the BIOS, or if I can that doesn't show on the display either.
I've not added any new hardware etc to the PC recently.
Everything is seated properly, the CPU and chassis fans all work, there is a green light on the mobo and the Ethernet cable socket lights up and flashes.
So I'm assuming it's a motherboard, which I don't have a spare of. Any other ideas before I go buy one?
The motherboard is an Asus A8N SLI AMD Socket 939, I'm not even sure they make Socket 939 boards any more ???
Thanks
It's definitely a motherboard. I can pull all the RAM and not get a beep or a whistle from the mobo in complaint. Does anyone know where I can get a Socket 939 board? Thanks. Or maybe a mobo + CPU combo that takes DDR RAM, of hich i have 4 x 512 mdules. I suspect I'm going to have to go for a new mobo CPU 'and' DDR3 RAM though.
Probably Ebay is your best bet, if you can get one new I would of thought it would be really expensive.
It is, £70 from Never-heard-of-us PC's. I might just bite the bullet and by a new box.
