Computer was working fine and I was moving the ethernet cable from one port to another and when I reattached it the computer just switched off...and on restart was beeping constantly.
I took out the battery on the mobo (to reset it) and it will restart fine and seems to be booting up (by sound of it anyways) but there is no video output. I have tested it with an older (known working) card but still nothing.
It also will not turn off by holding the power button and the only way I can power it off is by switching the off switch on the rear on the PSU.
should also say that I have cleared the CMOS, tried another VGA card, tried powering on with just basics installed and tried another monitor...always the same problem arrghh
