Hey lads, well today I decided to clean out my PC of all the dust, etc. I took the heat sink off, cleaned that, put it back in, same with the graphics card, installed a new fan, installed more USB ports. But... Now when I turn my pc on, I get no signal from my monitor, it just stays on Stand-by. Everything is plugged in correctly, I've double checked that, I tried booting with out the new fan and new USB Ports but had the same problem, if anyone has a sollution I'd be extreamly greatful.
This isn't on my new system, this is on my old system, which I am meant to be selling tomorrow.

Thanks in advance.
 
When you say you put the heatsink back in, did you reapply thermal compound and clean the old stuff off?

Do you have another gfx to check? I'd take out and reseat all RAM sticks and gfx card again too.
 
You haven't knocked a cable out have you? The 8 pin aux power connect to the motherboard?

Are you getting beeps from it? Does it sound like it's going through the normal boot process?

You didn't pull the cable out the back of the monitor did you?

Sorry I can't think of anything spectacular to fix it, just the obvious things.

I didn't clean off the old thermal compound, I didn't think that would make much difference, should I of cleaned it off and reapplied, would that make my monitor come off from standby?

I don't have another graphics card to check, but the graphics card seems to be working alright, it's powering up ok, and everything seems to be booting up fine, I'm just really stuck as to why my monitor won't come on when powering up. But thanks anyway guys, I'll try googling about this problem.
 
Re-seat the graphics card then, see if that helps. (As in take it out, then re-install it)

Make sure power is going to it if it requires it.

Did you take the cpu out at all last time? If you did, re-seat that as well.

does your grpahics card have a second dvi port or anything? Could try the monitor in one of them as well.

See if she does anything after the above....Is it not POSTing then? As in, no beeps when you turn the system on?
 
PCI-E (if applicable) to the GFX card?
GFX card in the correct slot (PCI-E slot 1 not slot 2 - V IMPORTANT)
DVI Cable in the correct port on GFX Card?
Monitor on correct input mode?
8 pin / 4 pin power into motherboard?
Molex plugged into board (gives more power to the PCI-E bus)
Try taking the RAM out and checking the traces for dust, same for the RAM slots.
 
everything is in th correct place, I didn't take out the cpu, only the heatsink. I'm going to try a different monitor, see if that's the problem, although it seemed fine before, I've taken the ram out, cleaned it off etc and that's not helped, I'm going to take off the heat sink again and see if the CPU is in properly.

I've been told to reset my bios, but I'm not 100% on how to do that, so I'll ask my friend who's a PC whizz to do that, as I don't want to do something I'm not sure on
 
If you are using a non-SSD hard drive, put your hand on it to see if you can feel any vibration / mechanical movement. If it is spinning up it points to something other than BIOS.

Huh? The HD will spin up as long as it has power. It's got nothing to do with the BIOS at all.

I'd definitely try resetting the CMOS (BIOS). Tell us which motherboard it is and we can show you how to do it.

It's a possible cause. However, reapplying will definitely help, as the thermal bond won't be as good now, and may cause overheating.
