no video for me.

[mortique]

alright, this has me stumped. i have a 17" flat panel monitor. it works fine on my laptop as a second display, and it used to work fine on my old homemade PC...

i just pulled the pc back out of the closet to put it to some greater use, but i decided to upgrade the CPU and mainboard. after installing the new items and replacing all the other components, i get no video signal when i turn the system on....

i have tried this monitor with 4 different mobo/vid card combinations but apparntly it hates PCs. still works fine on the mac...

i am working with a AMD Semperon 2200, biostar mobo, ATI all in wonder radeon, and a creative audigy card. anybody have any suggestions? could it be something incredibly stupid i overlooked?

Your LCD monitor works okay with your laptop. The laptop is a MAC? What's the resolution of your MAC laptop? Can your LCD display show up the sync frequencies? Jot these numbers down.
Now your desktop. Does it work with a CRT monitor? Again can you check the sync frequencies?
Your LCD may not work the frequencies throuwn out by the video cards on your PC. You don't even see the BIOS screens? Do you hear the PC booting, as if there was one monitor connected?

 

[mortique]

yes, the LCD works fine with my mac laptop, 1280x1024 resolution at 60hz. i don't know if it works on a crt as i don't have one available to test it. i did try another LCD with the same result...

no Bios screen, but it does sound like it is booting up....

what is the sync frequency? how would i find out the sync frequencies?

 

[mortique]

alright, i tested a CRT monitor on it and it appears the monitor is put to sleep as soon as the computer starts up...

You'll have to boot up in safe mode, and change your power settings.

Hmm, so even a monitor doesn't work. If you don't even see the BIOS screens, it looks like something's wrong with the video card.Sleep modes are usually driven by the presence (or not) of one of the sync signals. If an outputs has fried, the rest of the video card may work and your PC boot as normal. An oscilloscope would tell the story, but do you have an old video card catching dust in a box, even an old PCI one. You could give it a try in your system instead of the actual one?

i tried my other vid card, it didn't work either. both are AGP cards though...

 

[felixc]

It's getting challenging.

Do you have any other slotted card on your mobo? This afternoon I tought of your problem, as inserting a Firewire card on a PCI slot made the AGP video card fail on an Asus mobo. But it only was that the case was not properly aligned and the mobo was not letting the video card seat completely inside of the AGP connector.

Maybe a weird configuration problem. Have you tried removing the battery, to reset the CMOS RAM?

 

[mortique]

the only other card is the sound card, Creative Audigy Platinum. the card had worked fine before with my ATI vid card on an ASUS board. but that same configuration didn't work in the first place, so that's why i bought the new mobo and cpu (well, not the only reason, but it gave me justification .

haven't tried the battery thing yet, but i will give it shot tomorrow...

 

[felixc]

So you never got any video card to work with this mobo/CPU?

 

[felixc]

So you never got any video card to work with this mobo/CPU so far?

Oops the server failed, sorry!

 

[mortique]

no, not yet, i haven't been able to mess around with it cos i broke my hand. this has become a complex series of misfortunate events...

broke my hand"

Learned long time ago - no matter frustrated you get, hitting the monitor is not the cure! <grin>
