I have an AOpen PC and the signal to the monitor went out. I tested the monitor with another PC and is worked fine. I  replaced the vedio card but I still get a message on the monitor that says no signal. Before I take it in to best buy for a diognostic check I thought I would ask here to see if anyone had any ideas.

sounds like the video card, when you put in a video card you have to move the monitor plug from the default mainboard plug to the new video socket have you done this. Lots have been caught out with this when they spend lots of time trying to solve a problem.
Otherwise if it is the video card then put the monitor back to the mainboard onboard video socket if it has one.
What video card are you installing as many high teck ones require special installing to work properly.

I installed a Raderon 9600 se I bought from crucial.com
I took out the old card and put in the new one. I guess I just expected it to work. It did come with a driver CD but how do you intall it if there is nothing on the monitor but a "no signal" message?

What do you mean by moving the new card to a new socket? Do you not simple replace the new card into the socket where the old one was?

ok yur monitor is plugged into the back of your tower I know this maybe a bit daft but some folks do forget to move it, if you had an onboard video card the monitor plugs into the back of the tower to this, but when you install a Radeon video card or nvidia etc you have to move the monitor plug to the radeon card etc, sorry if i led you wrong. Just covering all tracks the simplest first.
I have seen lots of problems installing these cards and many others because the directx ran into trouble with windowsxp, as you dont even see your monitor on display then this is what came mind first.

Ok The correct proceedure to install these cards is usually on a newly formatted hd yep its true,
could you please let me know what the old card was first? You have to uninstall the old card remove all traces and I mean all traces or these cards wont work...  The Radeon>>Install the cd drivers first with this  then plug it in where the other card was and in that order then plug the monitor into it.
You have to have the latest catalyst drivers too.

Download this latest driver first.

I thank you all very much for your ideas but I decided to take it in to Best Buy.
The old card was a FOCE PA300 /Plus. At least this is what is says on the card. There is a good chance that there was nothing wrong with the old card to begin with.

Here is the series of events that led to the no signal message on the monitor.

Both the computer and the monitor are AOpen home made by some computer mad man down the street.
It started as an intermittent problem. When I would boot up the computer, the monitor would turn on, but then suddenly turn off before the complete boot up process.
After rebooting a few times the monitor would eventually stay on and I wouldn’t have anymore problems until the next time I tried to boot it up. Since I’m not the kind of person to leave the PC on all night the problem would occur everyday.

The number of times you would have to boot the computer before the monitor would stay on became more and more. Soon the monitor wouldn’t stay on at all unless you would let the computer just run for an hour or so and then reboot. It seemed as if something needed to be warmed up before the monitor would stay on.

I hooked up several other computers to the same monitor and had no problems what so ever. It would turn on right after the computer started up and stay on.

Soon it got to the point where I am today, which is that the AOpen tower will not turn on the monitor no matter how long I leave it running or number of times I reboot.  The monitor simple says, “NO SIGNAL”

Since I already ruled out the monitor being bad, I decided to replace the video card. Unfortunately it didn’t fix the problem. I took it to Best Buy and am waiting to hear back from them.  I’ll let you know what the out come is.

Tplayer

sounds good Tplayer
What is the difference between the other machines and yours??
do you have a network card remove it and see if that solves it, move the video card to a different slot. Any beeps??
other option reset cmos as it could be a bios glitch,

Load these two onto a floppy to run.Most diagnostic utilities function best when the system is booted from floppy without memory managers loaded. Check the docs within each archive for details.

Ok this is the verdict.
Best Buy is telling me that the mother board and the processor are bad. They are saying it would be more cost effective to buy a new computer than to fix the AOpen. On the other hand I think I can replace these components myself. I’m sure I can find the board easy enough but when they are referring to the processor is that the hard drive???

If so what are your recommendations assuming their findings are correct?

well a processor is  the cpu Central Processsing Unit, replacing a mainboard you have to format the hd run a fresh install, replacing the cpu same steps has to fit the mainboard specs,
The problem is unless you computer savvy you will have to get a tower that will fit the correct mainboard and a processor speed to match the mainboard a video card to match cpu, ram sticks  power pack etc.
Thats a major fitting job. Once yu have to change these two components it is really a new pc.. However its all fun learning. There is the easy way out. :)
 As you don't really know what a cpu is i'd say your probably better off buying the bits and pieces and get someone to assemble and fit it for you. Parts are always a lot cheaper online. You'll also learn a lot about genuine parts as computers sold as packages are not always the best buys as the cpmponenets can be OEM
 If you want a pc for games you'll need a fast processor, I personally prefer amd athlon as they are fast.
Take your time and look around..

  OEM
 
(pronounced as separate letters) Short for original equipment manufacturer, which is a misleading term for a company that has a special relationship with computer producers. OEMs buy computers in bulk and customize them for a particular application. They then sell the customized computer under their own name. The term is really a misnomer because OEMs are not the original manufacturers -- they are the customizers. And they don't carry much warranty..

I will just replace the board with one just like it. It's a AOpen AK73 Pro. I'm bidding on one on Ebay. When I get the PC back from Ebay I'll see what kind of processor it has and replace that with the same one as well.
Formatting the hard drive should be easy I've done it many. many times.
Thanks, I'll keep you posted.
