You're going to be pulling that board, to do the repair.

If that is double-sided tape they've used, you'll need a
bit of that as well. So the repair will actually be an
ugly job, not a nice neat one.


Maybe I'll just take the motherboard out and take it to the computer store
to let them install new fans. But at the computer store I use, I once
asked the guy if he'd put the processor on the motherboard with some
arctic silver for me. He pulled out a screwdriver to scrape the thermal
pad off the heatsink and that's when I told him I'd just do it myself. I
didn't see how he could use a screwdriver on a heatsink without scarring
the surface. That was the Abit KT7A-RAID I built back around 2000 or so.

[...]
And no matter how you do it, the clearances there are rather tight.
You have to make sure the fans don't jam on the backplate, or
on the heatsink on the other side of the fan.

[...]
Um, Good Luck,


Haha... Thanks. It'd be a shame to say this motherboard is "dead" just
because of a little $5.00 fan.

Well, I took out the motherboard and did manage to remove the two
heatsinks and the "heat bar" to get to the fan, which I did remove. But
before I even got that far, I noticed one capacitor by the PCIe slot that
was bulging a little and leaking some black stuff. Just to make sure, I
took the board to a computer repair shop and he verified that the
capacitor was bad. I asked if he could solder on a new one; he said it
could be done, but there would be no guarantee that the result would work.
So I re-installed an older Abit NF7 motherboard that I was using before.

I'm now starting a new thread with a different kind of problem: The
GeForce FX 5600 XT graphics card I'm using shows on the web that it will
pump out a 1920 x 1080 display, but the options panel doesn't have a
setting higher than 1600 x 1024.

On digital outputs such as DVI or HDMI, some early cards
didn't fully meet spec on clock speed. The clock can go
up to 165MHz on a compliant first-generation port. Some
of the "defective" designs, only meet eye opening at
135MHz.

In this picture, the DVI is only compliant at 141MHz.
And by the way, 141MHz is just the clock signal - there
are ten data bits serially, per clock bit, so the data
stream is 1410 Mbit/sec in that case. It's actually
pretty fast. (It's non-compliant,when the "colored" part
touches the deep blue "fixed template", on a normalized
waveform.)

http://www.tomshardware.co.uk/the-tf...w-1128-18.html

In order to hide their shame, the driver writers put in
resolution restrictions, so you won't see the side-effects
of non-compliant DVI or HDMI ports. In one case, the driver
writer even did the math wrong, and blocked something like
1440x900 as well. By preventing users from selecting high
resolutions on digital output ports, it prevents the
users from seeing "colored snow" mixed with their image info.

Now, a VGA port, the driver writer shouldn't have coded
a restriction in there. And 1920 or higher could well be
possible in that case. Of course, not all monitors have VGA
as an option, so there's no workaround if you don't have
VGA. You could perhaps, buy a VGA to DVI converter, but for
the price, you could also buy a new video card. Preferably,
a card at least one generation later than the "defective" ones.

This monitor has an input that LOOKS like a VGA input, but it's labeled
"D-SUB". And really, man, this PC is S-L-O-W. It amazes me now that I
could ever have enjoyed using it before. The graphics card only has 128
megabytes of video memory. I can't wait to get some new hardware, but
having this is better than having nothing at all...sort of. It won't even
play Farmville 2 worth a diddily damn.

The fan on the graphics card made a horrible, wavering whining noise. I
checked and it was spinning, but not very fast. I could actually make out
the fan blades spinning, but then it speeded up and isn't making noise
anymore. If I try to run at 1920 x 1080 through the VGA port, I might
just finish this card off. I only have a couple of other video cards. One
is a GeForce FX 5200, and the other is a GeForce 2 Ultra. Unfortunately I
gave my old GeForce 6800GT to a friend, thinking I'd never need it again.
How wrong I was! I'd LOVE to have that card back right now because it
would run fine in this system. It was what I was using before I built the
one that died.

Web research shows this monitor does have a VGA input, so I guess that's
what the "D-SUB" actually is. I don't know why it's labeled that way. I'm
tired enough of this non-preferred resolution and weird appearance of
fonts that I'm willing to try VGA to see if I can get there without frying
the video card. It's supposed to do up to 2550 x something at 100 Hz,
which is pretty amazing, but I only need 60 Hz for this monitor. Maybe
that'll help keep the burners down.

Okay! I'm now running with the VGA cable and 1920 x 1080! It looks a lot
better like this than it did running subresolution with the DVI cable. I'm
happy with this until my video card fries or I get a new rig.

Thanks for all the help. You've been very patient.

I doubt this thing will run Final Fantasy XI at 1920 x 1080 at a decent
frame rate, but the game itself is limited to 30FPS, so maybe it'll be
okay. In areas of high density traffic from other players, even with my
GeForce 7950 GTOC, the frame rate would sometimes drop to 5FPS, but it's
still fun.

Good lord! I was using Google Chrome for about five minutes and it
suddenly crashed with a message:

"Woah! Google Chrome as crashed. Relaunched now?"

And when I relaunch, I immediately get the same message. :\

Every time I try something new with this system, something goes wrong.
/sigh Cause and effect?

There are some suggestions here. I take it one of the suggestions, moves
some registry stuff out of the way.

http://support.google.com/chrome/bin...&answer=142063

But what I'd be searching for is "Hardware Acceleration" settings.

Adobe Flash has a hardware acceleration setting. There is a dialog
that opens in the middle of a Flash movie window, that includes a
tick box for hardware acceleration.

Browsers have also taken to hardware acceleration.

But with your hardware (and mine), our cards don't have a lot to
offer. Our programmable shaders standard is probably too old for
that sort of thing. Video cards have had 2D acceleration (bitblt)
for a long time. I don't know if they bother with that or not,
as it's hardly worth it. Video cards have had IDCT for some
forms of movie decoding, but that isn't a "general purpose" form
of acceleration. I can't imagine what construct would be dying
with the hardware acceleration.

When the browser session starts, you want to tell it to *not* load
the last windows. Where you were surfing, the source code
tipped over your browser. So you'd want to start a fresh session,
and see if the browser will stay up with just a blank page
in view. If your home page is "Youtube", then that might immediately
fire up Adobe Flash, and test Flash hardware acceleration.

Maybe the browser has a "Safe Mode" or load without plugins ?
At least for one session, before you turn it all back on again
and re-test.

Anyway, that's where I'd head. At least, until you indicate that
something unrelated to video seems to be crashing. If Wordpad
was crashing, you'd be looking at CPU or RAM perhaps, as much as
anything else. But with browsers, there are a few forms of
hardware acceleration. Either in plugins, or in the main
body of the browser code. Older browser code, doesn't use hardware
acceleration, and in a way, you can blame the work Adobe Flash did,
for attracting others to take that route. The thing is, the code
they write for that, doesn't seem to be quite the same quality
as code for 3D games. It's almost like they don't have a big
enough testing group, to make sure it all works.

After I let Chrome rest for a while, I was magically able to relaunch it
normally. So far it hasn't happened again, but since that was the first
time I ever saw that message (and the first time I had ever used this
monitor with a VGA cable), of course, all my flags flew out.

Thanks again!
