Video Problem

[Dell Christopher]

HP Pavilion Elite e9240f desktop computer
Windows 7 Home Premium (64 bit)
ATI Radeon HD4650 video card

Everything was fine until I booted up this morning. Now, all I get is a
blinking cursor in the lower left corner of a black screen and white lines
running back and forth along the very bottom of the screen. Here is what
I've tried so far:

* F8 and F11 (System Recovery) - same result
* unscrewed the caps for the integrated VGA and DVI inputs, and tried those
instead - same result
* removed ATI Radeon video card and tried another standalone video card -
same result

This is really perplexing and I can't think of anything else to try. Does
anyone have any other ideas? All input is appreciated.

Thanks!

I'd try using a trusted monitor lead, and then another monitor. If you
haven't got them, try using your monitor and lead on another PC to
eliminate them from your bin list.

Can you boot to the Bios screen?

Can you boot to the Bios screen?

That would rule out a blown monitor.

That would rule out a blown monitor.

That's what I was thinking, especially if it were a CRT monitor. The OP
mentioned DVI and few CRT monitors had a digital signal input; however,
the IBM P260, a CRT monitor, had a DVI input. It didn't use any digital
info, just analog via DVI-A (DVI analog only). If it were a CRT
monitor, having all the lines squashed together in one place means there
is a vertical scan problem so the deflection yoke or the circuits to it
(e.g., bad capacitor, flyback diode) are defective.

http://www.repairfaq.org/REPAIR/F_monfaq6.html#MONFAQ_013

In any case, the symptom described looks to be a problem with the
monitor. Adjusting the vertical sync rate (on the monitor) beyond the
capability of the logic could also result in lack of vertical scanning.
The OP didn't say if the problem exists at a cold boot when the BIOS
screen is displayed (which doesn't involve any OS or any drivers
installed in it) or only after Windows has loaded (which could be the
result of tweaking the display qualities to outside the specs the
monitor can handle).

That would rule out a blown monitor.

Doesn't the blinking cursor also rule out a blown monitor?

It's a video problem.
OK, you tried system recovery and changed your video card. The latter is the
most important. I would think it's Windows or your Mobo.
Try to reinstall Windows and try to save your personal files beforehand on a
USB drive. Recover them afterwards.
Otherwise, try another Mobo.

Can you boot to the Bios screen?

I think trying to enter the BIOS screen is a good test, because it
allows video display quality to be checked without loading an OS.
Even if the result isn't a high resolution test, and isn't very
colorful.

At the same time, you can check the storage page in the BIOS,
and verify that the disk drive (disk drive name) is showing up.

Being a curious kinda guy, I might be tempted to pull the
other card showing in this picture. It could be a TV tuner card.
Pulling stuff out of the computer, is all part of a "simplify
and retest" strategy.

Many thanks for the responses. I failed to mention that I have also tried 3
separate monitors.

Also, I do see the light blue HP splash screen with the various F key
options at the bottom when I power up the computer. But, whether I hit F8
or F11, it still goes to that black screen with the stuff at the bottom.
So, even though I have backed up my data, I don't have the option of simply
doing the System Recovery.

As an outside chance, have you tried a different keyboard?

If it's not responding to the Motherboard's check for a keyboard at
boot, that could give the symptoms you describe.

Since it also sounds to me like a BIOS problem, I'd verify it by using a
live CD or DVD of some operating system (any OS), or a backup program
recovery boot disk (any backup program), to see if that disk boots OK.

If it does, it points to a problem with the boot hard drive. If it
doesn't, then maybe my guess about the BIOS is correct.

What happens when you press F10 when you start the computer? Can you get
to the BIOS screen?

 

[Dell Christopher]

I haven't tried BIOS yet but, if I can get into system set-up, should I just
have it load "system defaults"? Or is there any other setting I should
check?

You could go into the health screen, if it has one, and check what it
thinks the voltages are.

 

[Dell Christopher]

OK, I was able to boot into system set-up. I tried to have it load
defaults, but that didn't work either.

Any other suggestions on what to check for in set-up? Thanks!

By "system set-up", do you mean the BIOS setup?

If "yes", and if the BIOS screens looked OK, then your monitor and
graphics system are apparently working.

By "that didn't work", do you mean you still get the funny screen when
Windows tries to boot?

If "yes", then I suspect a hard-drive failure or a hard-drive controller
failure.

In my HP laptop BIOS there is an option to run a diagnostic to check the
HD. I assume there is one in your HP desktop BIOS.. If so, try running
it.

One other thing you could do is try to boot from a linux live CD. Or
better still, if you can download UBCD (http://www.ultimatebootcd.com/)
boot from that and run the diagnostics on it. If you can boot from
either CD, it suggests, as Gene has noted, HD failure.

If that is the case, do you have a system image that you could restore
to a replacement HD?

 

[Don Phillipson]

Doesn't the blinking cursor also rule out a blown monitor?

Probably not. The first test for a monitor is whether (connected
or not) it can display its own adjustment menu (responding to its
own controls.)

I should have thought of this earlier. Here is a link to a 19 second video
of the computer booting up:
