As the subject says my P.C. wont boot.....I plug in the motherboard (its a desktop)..It lights up and whirrs..
I plug in the moniter and the light at the back flickers....It does briefly say theres no signal...but then nothing

Probably not the same...but my PC would not boot up for a few days the other week....or so I thought!....just a black screen, no signal etc...had to keep clicking the tower button and eventually it would turn on.
Anyway, guess what, it turned out to be the monitor and NOT the PC!
I bought a new one (27") and all working fine.
Have you a spare monitor you could try out first?

I find the best place to start is with a Hiren's disc. Once I have that loaded I can check the HD using the tools it has and generally sort things out.
Loose connectors can cause problems.
A graphics card on its last legs can work intermittently. If you get an image with Hiren's then that should eliminate that.
The no signal may be misleading to be honest. It disappearing can indicate that the graphics card is sending somehting but only by trying out something like Hiren's can you be sure.

Happened to me, so I removed the hard drive and gave away the left overs to freecycle. I plugged in my new spare keyboard into the lappy, then plugged in my original monitor to the lappy, which now works just like a stand alone PC, with the convenience of a normal keyboard and monitor.
Oh yes, and I bought a hard drive docking station, this plugged into the USB sockets so I could recover all my photos etc. Cool aye?
Pete.
PS and its our 59th wedding anniversary today.

Fans turning means nothing, it doesn't even mean the PSU is working correctly - but it probably is OK, here's what I usually do (assuming it's not the monitor as Lynnrose suggested, that's quite rare) ... 1) Reset the BIOS via the jumper on the motherboard, that has worked quite a few times for me, and as it's a 2 second job, I usually try that first unless there's beep errors that suggest it's something else. Not all boards have the reset jumpers though, but if they do they'll be near the round CMOS battery 2) Nothing on screen just means it's failed one of it's start-up checks, which could be anything and probably nothing to do with graphics, but I usually check that next anyway. If it's a board with on-board graphics and an external graphics card, then remove the card and try the on-board graphics instead. If you have a spare card, try that next. If it's just on-board graphics and no external graphics, you could try to borrow a graphics card to test it - but, that is a last resort usually because on-board graphics very rarely die in my experience 3) And maybe this should be 2, because it's far more common for the RAM to be a problem in cases like this. Most people should have at least 2 sticks of RAM installed, so try each one on it's own first to see which one has become faulty or died. It is uncommon for both to have gone, so one should get it booting, if that was the problem in the first place. If you have a spare stick , always worth trying that too - just in case 4) PSU, as I said before, just because the fans are moving, doesn't mean sufficient power is being generated to start the PC. A fan only takes a few volts to get it moving, the CPU a whole lot more. It's quite difficult to swap PSU's if you've never done it before, but it's pretty straightforward if you look at it logically. Most people won't have a spare PSU knocking around, so unless you can borrow one from a techie friend, you'll either have to buy one, or just hope it's not that 5) Motherboard and/or CPU. Very rare for the CPU to be faulty, unless you've tried overclocking or the CPU fan has stopped working and it's fried itself. But motherboards going down is a lot more common than it should be. Changing the board is obviously not for the novice, because you're basically building the whole PC. Can be quite expensive, but it's the least likely of the possible faults, so hopefully one of the previous steps has worked ..... and congratulations Pete to both of you  ) |

Thanks mikkh, yes and I can remember reset bios by remove battery the round battery, then putting it back in again. That was a long time ago when we had 486s I think it was.

If it tells you there is no signal, the monitor must be working. Although one of the plugs on the cable to the computer could be loose. If its a HDMI cable, just moving something can disturb a cable a bit. No screws like the D type and even them can be loose. Being quick and easy I would try and reset the BIOS first, that will often be the trouble. If not that, the module in number one slot of the memory next. Pull them all out and try any one except the one that was there, number one is nearest the CPU. If it works test them all before putting more than one in. If that dont work try a couple of hard clouts with a 2 pound hammer.
