Hi

I've just tried to plug in a slave disc drive to my computer. I unplugged the fan that i've got so i could get inside the tower easier. Now when i've plugged it back in, the monitor won't turn on, it comes up with no input signal. I can get the fan to work again, the power comes on and the cd drive works but the monitor just won't work! I don't understand why as i've tried every combination of red/yellow/black wire into the fan's wire and it just won't work again now. ANY IDEAS? I'm ready to throw this out of this window, it's been one thing after another with this lately!

Try to reseat the video card. It may be that simple. It could have been bumped when you were inside the case and just needs to be reseated. If you have a spare card try swaping to see if it works.

Hi Championless,

What fan are you speaking about here? Is it just a fan fitted to one of the case panels?
If so it doesn't matter whether it is running or not as far as booting the system goes. In that case your problem lies elsewhere.

You have integrated graphics so its not a card seating problem, it could be a memory seating problem though. Try unplugging and replugging your memory stick(s).

Is the new hard drive still in the system? If so remove it, there may be a conflict with the original hard drive. When you say the CD drive "works" what do you mean?

It's not the video card coz it's on board, i've checked the cables and memory and that hasn't fixed it. It did actually turn on once or twice but then froze when it got to boot from the hard drive, but the hard drive was working alright before i started this...

Since this happened after you were inside the case and you have integrated video its quite possible that you have damaged the video chip with static electricity if you inadvertantly touched it. Were you grounded to the case while you were inside there?

If you can, try a video card in one of the slots. According to the ASRock webpage for that mobo you have a choice of either AGP or PCI to put a card in.

My point is that I think the on board video chip is fried. You need to buy a video card. Luckily you can get either a PCI or AGP card and carry on. Your on board video was 64MB so you can find a fairly cheap replacement or you can upgrade to 128MB.

Please do NOT use a 3.3V AGP card on the AGP slot of this motherboard!
It may cause permanent damage! For the voltage information of your
graphics card, please check with the graphics card vendors.


You can get the mobo manual here. Page 17 shows the fan connectors.

You can also try another monitor to eliminate that as the problem.
