Blank Monitor Problem

By s-rochon ·
Hey everyone, I just recently bought a computer and everything was working fine with, perfectly fine up until I moved the location of the computer from my upper floor to my lower floor. I plug everything in in the exact same way but when I start it up there is no power signal for the monitor, but it has power. If I shut the monitor on a satifying and glowing green light turns on and ACER appears on screen and then it is replaced by the words No Signal and the pretty green light by a depressing orange one. then the screen turns completely blank. the computer and all it's components seem to be running fine.

I've tried opening up the computer and changing the video card and unplugging and plugging every cord back in but to no avail.

I'm really stumped especially since everything was working so perfectly before.

Here are a few things you might like to know:
My monitor is a ACER AL1**6W and my current videocard is nvidia 8800 320mb

If there is anything else you need to know just ask.

Thanks in advance.

Monitor issues

by Travler92 In reply to Blank Monitor Problem

Check that the card is seated correctly. Also check the pins on the cable have not been bent or pushed back.
Try another monitor or card if you have one.

Good luck

Thanks for the advice.

The card is seated fine, and all the pins look fine, although looks can be deceiving. I have tried another video card and it produced the same effect. So as useless (sorry to say that) as your advice was, thank you
and thanks for the luck to.

Along with the first poster

by The Scummy One In reply to Blank Monitor Problem

make sure that the monitor is plugged into the right video card, if there is a built-in card make sure that it is not the one that is plugged in.

On the monitor, check the cable connections as something may be loose (data cable).

Checked.

Video card is right, cable connections are fine (as far as I can tell) I've unplugged and re-plugged them about one thousand times. Thanks anyhow though.

Check CMOS battery

by mjd420nova In reply to Blank Monitor Problem

I've seen some very strange things happen when moving units from one location to another. The CMOS battery may have failed and this puts the BIOS into default and it might not recognize the video card. Try booting into the BIOS and see what the video is set for. I think ACEr uses the DEL key on boot up to enter the BIOS. Give that a whirl.

Thanks for the advice, that's something I haven't tried. I'll try it as soon as I can and tell you how that works out.

Problem

I tried booting while holding DEL and then I tried with a few other keys but I never get any image on screen. I'm at a loss of what to try next.

Check memory.

by Mayhem1969 In reply to Blank Monitor Problem

Make sure you did not knock your memory loose while moving. You may also want to check your other connections, power supply, hdd, etc. It could also be a bad video card, swap it with another if you can.

Looks fine from here.

by s-rochon In reply to Check memory.

Well I thank you for the advice I'm afraid it is quite useless. Let me just tell everyone that I've checked, double-checked and did those both again that every cable wire and cards are connected properly. I'm really drawing a blank as to what the problem is. And I have tried another video card, same problem.
