OK, brand new laptop.. Sold the desktop to get it. Anyhow, every now and then, a line appears across the screen near the top, like a flicker. Sometimes it happens in the middle. What would cause this? Should I be concerned? Driver issue?

Here is a video of problem. Near the end you will see what I am talking about, at the top of the screen. I have installed different drivers. I'll see if that helps.

Could be a bad GPU. If new drivers don't fix it, send it back.

have you enabled/forced vsync?

Well the new drivers are instalkled. I'm still getting some flickering. I turned off a few startup programs dealing with the video card using MSCONFIG, restarted, and so far there are no issues.

Also tried running Ubuntu. No issues while using Linux.

If the GPU is bad that means the CPU is bad since the GPU is built into the CPU.

UPDATE: Took off the back off the notebook. Made sure all of the screws are tight. Turns out a few on the CPU were not. Re-seated the RAM and hard drive. Made sure the display connector wasn't lose. so far, no issues. I'm still worried that it flickered in the first place.

I doubt the GPU is built into the CPU ...The GPU is more then likely built onto the Motherboard separately from the CPU ..

 

I would take it back ... I have doubts it's your GPU or drivers... Is it only at the top of the window or the Monitor?

 

If you move the window top to the bottom does it still do it? or is it still at the top of the monitor ?

if it is following the Window the I would say yes it's your GPU.

or

I say it's not the GPU or drivers cause, I would think if it was, it wouldn't just be at the top of a window..

I think it is your monitor if it is only at the top of it.  aka bad pixels

 

just I thought...

It's an AMD E-450 processor. The GPU is built into the CPU. See here under notes:

http://www.cpu-world.com/CPUs/Bobcat/AMD-E%20Series%20E-450.html

It just happens at the top, sometimes in the middle or near the bottom. However since peeking inside the screen hasn't given me any trouble.

well then I would take it back and get one with the CPU and GPU are on the mother board separately not all rolled into the CPU   or replace it...

it sounds like the GPU-CPU is bad.. and it's a bad Ideal that they would put the two together...

 

sorry I can't help have no Ideal

I had/have a similar issue with a HP Pavilion dv6 (it looks like we have similar models; your monitor bumpers are in the same place at least), but I only get it on the desktop and in Google Chrome, and sometimes in VSExpress.  I can play games for hours without any graphics artifacts, but if it's just displaying the desktop, I get this flickering multi-colored one pixel thick line that jumps around in the top half of the display.

I didn't crack the unit open or anything (it's still under warranty), but after several system/driver updates and reboots, I haven't had the problem in a week now.  Oddly enough, it seems to have gone away because I actually shut the computer down earlier this week.  I don't know what fixed it (I did the same stuff I've been doing for a month now).  I still have a month on warranty, so I'm watching out for it.  I'd just hate to have to replace the unit after downloading 100 GB of games and software...I do not have the quickest internet connection.

You took the back off Kona?  I hope no one can tell and it does not void your warranty.

Yep, take it back, it may be an intermittent problem. Then the warranty will have just expired when it becomes a full blown problem, that's "Sod's Law"!

You will also have peace of mind, you won't have to wonder when its gonna act up again, it will!

It has a panel that can be removed so one can add or revome RAM or the hard drive. Most units have this panel. What makes this notebook unique is that one can also see the CPU and CPU fan while the panel is off and look at those if need be.

@DC: Most new processors have the GPU built in. That's the way things are headed.

@Quicksilver: It will have to wait to be taken back, as Fry's is 60 or so miles away and I have an empty gas tank till payday.

See if you can capture it with something like Jing.  If it shows up on the video, then it's a video card-related issue.  If not, it's a monitor-related issue.

I already captured the problem and posted a video. What would posting a screenshot using Jing accomplish? Is there a program out there that will just test the GPU? That way I can put stress on the GPU to see if I can reproduce the problem. I doubt it's the LCD monitor itself.

Using Jing, it will capture what the video card is telling the monitor to display.  If it shows up in that video, then that means the video card is telling it to flicker.  If the issue is with the monitor, then the flicker won't show up, because Jing isn't capturing what the monitor is showing, only the video card.  The method you used to take the video can't distinguish between the two.

Well I can't get that machine to flicker right now so what do you suggest?
