Hi All

I need some tips on how to fix my PC. the problem is whenever i turn my computer on my monitor keep saying "no signal" but the system is on. i mean fan is running and everything looks running also. but monitor keep saying "no signal error" can somebody recommend where should i start.
Thanks for your help!!

You'd know if the machine had booted by reason of the HDD activity. It should show activity for a couple of minutes during boot and then die down.

My guess is that it isn't booting although I would have expected at least the boot screeb to have shown.

So, at first sight, it seems like your PC is buggered (assuming you've checked your VGA or DVI cable).

Let us know more detail please.

try to unplug and then plug again your monitor's cable into your vga maybe this is the problem that your cable cracked

well i tried on two different monitors and it did the same thing.

i have checked my VGA and its working fine.

Do you try your video card in another computer?Is same result?

Are you using onboard video or an addin card? Does the card work on other pcs? Does the monitor work on other pcs?

You don't say very much. if your machine won't boot, how have you checked your VGA?

So, when you try and boot, what happens? Does your disk run for a minute or two? Do the keyboard lights flash on during boot? Is there anything on the screen during the BIOS bootup phase?

If there's nothing displayd at the power on par (BIOS Stage, Power On Self Test), and if as you say VGA is OK (how do you know), then the PC simply isn't booting.

When booting the only things needed to prove it's working are the Boot ROM (which reads CMOS settings), the CPU to enable instructions issued by the Boot ROM to execute, supporting motherboard circuitry to deliver display characters to the VGA which must also work. If RAM is bad, the PC will beep under BIOS control. I don't think there's a beep if VGA isn't working - BIOS doesn't care. When the POST is complete, the BIOS goes to disk to bring in more instructions (Boot Loader) in order to get Windows going.

SO we need more infor to diagnose your problem - what's happening along the narrative I've just provided?

i have tried those monitors on my laptop and they works fine. so i m guess nothing wrong with the monitors. I have both video card on board and add on so whenever i plug that in either one same problem.

So, what about the other stuff I've said?

On the very little you've told us, and assuming there is no POST screen display, I'd diagnose your PC as electronically dead or damaged.
