BleepingComputer.com: No Input Signal Problem

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!


My computer has the following specs :-

CPU: AMD SEMPERON 2400+ 333Mhz FSB
HARD DISC 80 GIG 7200 RPM
Motherboard : Asrock K7S41-GX333FSB & 400DDR
Memory : 1GB DDR Memory
Video Card : REAL 256 INTEGRATED 3D GRAPHICS GPU
DVD-RW : YES
Floppy : 1.44MB Floppy Drive
Network Card : 10/100 Fast Ethernet Network Controller
USB : 4X REAR USB, 2X FRONT USB PORTS
Sound Card : 5.1 3D audio processing unit (APU)
Case : ice box zorro gamer ATX Case w/450 WATT PS and Front USB Ports
Keyboard / Mouse : Ezkey Silver/black 10 Hot Key Button Mouse & Labtec Internet Keyboard
Speakers : Made by Trust
Operating System : Windows XP Pro with SP2
Monitor: Digimate L-1715 17" TFT Monitor

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.

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.

I don't have a spare video card to put in and the one thats there is on board. Do you have any other ideas?

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.

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.

Just a thought but have you removed the Slave disk drive? and tried it without that?

Thanks, but i've somehow managed to solve it, i tried plugging everything in again and for some reason it works now.
