Hi again Paul,
I want to make a quick update about display problem with my old
monitor:

It occured again for sometimes, when the screen went away i slapped
powerful on the monitor lol and screen came back! This method
brought display back 2 times with my slap to the monitor.

I hope it's not an coincidence, i just determined this for 2 times
with my slap to the monitor. I think VGA card is innocent.

Update about AGP warning LED situation:

The AGP LED lits intermittently / irregularly sometimes in a day, but
i can boot up fine and play 3D games, the light isn't stable and isn't
steady. Lights intermittently with my 4 year-old graphic card which
works fine.

Should i concern?

We know that something is not working right.

You have two choices. Have a professional shop take it apart
and try to repair it.

Or continue to use it as it is.

If you don't want to waste money on the machine, continue to
use it. It is apparent from your description, that "AGP warn"
cannot turn off your power supply, for some reason, so having
the LED go on and off, doesn't seem to mean anything at all.

As you've already noted, the LED is on when the AGP slot has
no card in it. And it isn't supposed to do that. The LED
should remain off, if no AGP card is present. The transistor
circuit is supposed to check, by some means, that a card
is present, before the LED can be enabled. That is what
it is supposed to do.

Hi Paul,
I contacted the distribitor and they claimed that the motherboard is
too old to repair, they can't repair. Haven't tested newly, but
sometimes AGP led was lighting on last test for some days ago.
Currently the AGP card is inserted and works well, boots and plays 3D
and at the same time sometimes but not always AGP Led lits
intermittently with no sense.

Additionatly, in last tests which were a few days ago, if there was no
card in the slot, the LED was lighting then i surprised as well and
pressed power button, no boot up, no fan no action. It was doing its
job even there was no card installed

Since then, the AGP card is inserted and works, sometimes but not
always if i touch, poke the card slightly LED goes and goes off for an
instant (a few seconds), sometimes it comes without my hand touch by
itself.

However, in previous messages i mentioned a burn-smoke coming from AGP
card or near place AGP slot, maybe this small was an indication of a
burned AGP warning circuit as some symptoms may refer that.

I hope you aggree and analyzed my symptoms?

However, thanks for your care, it would be good to receive your e-mail
or you can mail me at:

kimiraikkonen85.RemoveThis@gmail.com that i can learn yours

Regards.

Paul,
The latest situation:

About AGP LED problem: Sometimes the AGP warning LED doensn't light
for a long time, sometimes it lits by itself without touching the
card, and this light is usually intermittent and not so bright.

And.. touching this card usually is not the reason, because usually it
lits by itself. But although this, there's no error message or problem
during 3d or graphic operation that card was my existing card for many
years has a full compatability with +1.5V. And this intermittent LED
sometimes goes off if i plug out power cord and re-plug it etc...

About monitor problem: The screen frequently goes off and comes back
usually after i slap ad punch it sometimes screen comes less than
5 seconds sometimes i need to punch the monitor, i don't there's a
relationship between my 10 year old CRT monitor and this AGP led
problem.

Shaun, meanwhile, the only cleaner equipment i have is a Philips
contact spray but don't think it'll make things better.

However i want to ask about my AGP LED, besides my old monitors self
problem:

Is there a hardware danger indication while this light is lighting
intermittently / irregularly? Paul has said it's worthless at the
moment and just an annoyance, still you agree?

I hope you help.

Thanks.

Additionaly, i have a suspicion. With having no relationship between
monitor problem and AGP led problem, (while having monitor problem
before AGP led issue), i thought it was because my AGP card and
decided to plug out and examine the card. If i remember correct, i
haven't plugged power cord of pc (or didn't switch off PSU) afterwards
AGP led problem began to arise. Just i wanted to notice.

Can all that irregular / intermittent and "fake" AGP LED warning light
problems become because of removing AGP card without plugging power
cord?

Thanks!

Doesn't anyone spray CO cleaner liberally into the slot that's giving
trouble these days, then check the card contacts, clean with a new eraser if
needed and maybe do a few insertion cycles? I find that usually fixes
AGP/PCIe problems (and a lot of RAM problems too). They're prone to getting
dust creep into the slot as they're often getting a lot of turbulence from
the CPU fan.

See my previous post. I find that often dirty contacts can cause all sorts
of problems. Spray CO cleaner liberally into the slot (power cord removed!)
until it runs out. It can't hurt to try, just cost a few bucks for the CO
cleaner.

It is good to keep these discussions in the newsgroup rather than go to
email. I've been following this topic with interest and would be very
disappointed if it were to go private now. You never know when a similar
situation could arise for someone else and what's read here could help them
resolve it.

Hi again,
Had no answer regarding to my some previous posts but i want to update
the situation which is weird:

AGP warning LED is staying steady ON with my existing Geforce4 MX 440
card(15V), the system can boot fine can play 3D games.

I'm not sure why AGP Warning LED is on for my 4 year-old existing VGA
card and my mobo P4B533 can boot fine with that LED is stayed steady
ON. It seems the LED's circuit is not working and LED is lying cause
i've used the same VGA card for many years with no AGP LED error.

So is there a real danger regarding to mobo or especially VGA card
although AGP warning LED is fake?

Thanks for ideas.
