Hi, My PC jsut switched off in the middle of me working, now when I hit the power button, the Power light comes on, the fan started to work, and the Keyboard lights flash as normal.
However, the monitor never comes on and nothing else happens. It does not even start to boot.
Does anyone have any ideas as to the problem ? The Power Supply seems to be working but just not booting. It does not seem to start the Hard Disk.
Could the Motherbaord of blown ? or the Hard disk totally shafted ?
Any thoughts/ideas most welcomed.
Thanks in advance.

Most systems check the video card before they begin the boot sequence. If your machine has no display at all, and no boot - I would target this area first.
You didn't mention, but I'll ask anyway - are you getting any beep codes at initial startup ? And, is this an integrated graphics board or a PCI/AGP card ?
If PCI or AGP, make sure that the card is good -try it in another machine. If it checks out, try reseating the card in your machine - make sure all of the contacts are clean and lined up correctly.
If still no display, try another card (that you know is good). If it doesn't work, I would blame the slot in the mobo. - I have seen videocards go bad and damage the slot they were in.
What kind of video card do you have - and what mobo is it in?
Try this and let me know how you fare.

Thanks for the response. The Video in a TNT NVDIO 32 MB thing.
I've taken all the other cards out, except the video one. I'lll give that a go
I'll let you know how I get on.

Here is the latest...
Pulled out all the cards. So just motherboard and Hard disk are powered up.
Turn the PC on, Keyboard and power lights go on... then nothing..
No beeps or anything.
Tried this with another PSU and still the same.
I suspect the Mother board has gone awol.... just hope the hard disk is still ok !!!
Any more thoughts most welcome

The Bios on the motherboard may be at fault, try clearing the cmos via the jumper or remove the cmos battery for a few minutes with the power cord removed, this should set your cmos back to default settings. If this doesn't work suspect the motherboard itself is faulty.

I had a problem pretty similar to this, except I never actually managed to get the PC to ever boot up - I didnt get any bleeps or anytihng.
In the end it turned out to b a dodgy motherboard, so I replaced it and then everything worked!
