Troubleshooting advice needed for "No Signal" on monitor screen
I went to turn on my computer today which usually boots straight up only to see "No Signal" on the monitor screen.
I tried a second monitor, same problem. At this point I considered the Video card may be faulty but thought it best to get more information on the correct procedure to follow to correct this fault.
I can hear the hard drive start up and all other system hardware appears to get power.I would be very grateful for further trouble shooting advice.

Hi PeteJThomas
Thanks, I already removed the card from the slot wiped the contacts then re-seated it, even lightly sprayed CO contact cleaner then wiped again but nothing.

Do you have any other slots you can try the card in? It's rare (as in I've never seen it myself) but vaguely possible the problem is there. If it's a PCI-E slot and you have another, you could try your card in there too...
It definitely sounds like the card itself, but worth checking I suppose before you spend any money. Does the graphics card itself appear to power up? Does it have a cooling fan / any visible LEDs which come on etc?

Hi PeteJThomas,
The board has other PCI slots but I only have the one AGP video card and there is only one AGP slot on the board. The card is a Radeon 9550 and only has a fixed, smallish heat sink on one side and no LED indicators or fans. Its approximately three and a half years old. I agree with you about checking before buying a new card , but I think there is a good chance it is not working.

Yup, well unless you have another PC laying around somewhere you can test the card in, I'm not sure that there's much more you can do without swapping out the card. There's a possibility that other components are the cause, but I'd start with the card personally...
Let us know once you've tried a new one?

Hi PeteJThomas,
Many thanks, I plan to get a new card, and even if thats not the cause , its good to have a spare.
I will let the forum know as soon as I have a result.

Check video card for Sacon FZ series caps.
If you have them the card is a junker.

So far, I havent noticed any bulging caps on the board or the card but will go over them again and will post my findings.

Hi
just an update on my problem. Was able to test the AGP card on another machine and it works quite OK.
Went over the motherboard carefully and could see no burst or bulging capacitors. Changed the RAM with known good RAM , tried RAM in both RAM slots. Still getting the "No Signal" on the monitor.I am thinking its the motherboard that has a problem.

I guess I should have noted those caps I mentioned -have- been found on that specific series of Asus boards.
There are many other problem caps just not reported [yet?] on those boards.

Cable was swapped with another, same thing happened. No response from monitor when PC is switched on but other components are recieving power ok eg: drive spins CD drawer accepts CD and spins up etc but nothing on screen. No alternative graphic adapter at all ie: no onboard graphics.
Unfortuneatly I dont have another card and will go out tomorrow to get one as the stores are closed for the day where I live.
