Windows 7 Pixelated Screen Problem

JB441 · Oct 27, 2009

Hey everyone, I have an interesting problem.

I am not sure if it is a hardware or software, so please move to the appropriate forum if necessary.

A while back, I downloaded the Windows 7 RC 7100 build and did a fresh install from XP. Everything worked fine except for when I would log on or off, or I would use certain popups through control panel or anything, my entire monitor would have black squares pop up like it was pixelated or shattered. I thought it was a RC problem.

I recently just bought and installed a Windows 7 Home 64 bit OEM and it is doing the same thing. I've attatched a picture of what it looks like when I run a pop up through my control panel (In this case, the windows computer assesment thing). The screen does the same thing when I log on or off still. I have a Nvidia GeForce 7600 GS AGP and yes, I have updated the driver for Win7 64bit. Any help would be great!!!

Thanks!

JB

Quick question: when you downloaded the latest drivers, did you use Windows Update or did you download them directly from the manufacturer's site?

Downloaded from the manufacture's (nVidia) website. Windows update never found a new driver for my video card.

Try something real quick: go into Device Manager, right click on your video card, and select "uninstall".
Reboot your computer, and let Windows automatically install the drivers. Let us know how it works out!

Ok, so after I uninstalled it and it restarted, the log on and off screen looked normal. But after windows installed the driver NVIDIA GeFroce 7600 GS (Microsoft Corporation WDDM), I restarted it and the log on screen went back to being pixelated and looking shattered.

hmm... that's funny. Try this: uninstall all drivers, and immediately run the installer package you downloaded from nVidia.

It actually did not let me install it because I did not have a current driver installed. So I reverted back to what windows installed, then installed the nVidia one and it is still doing the same thing and actually now, when the desktop loads, the screen goes black, then back to normal.

Funny... I don't know what to tell you, other than that I am sorry it is happening.

JB441 · Oct 27, 2009

Could it have anything to do with Direct X or any other kind of graphics things?

Jonathan_King · Oct 27, 2009

I am the wrong person to ask. My best guess has to do with the drivers.

JB441 · Oct 29, 2009

Well, I just installed FSX and apparently it has to disable AERO and the Win7 colors change to basic and whatnot and my whole screen goes shattered and I can't even read anything while in the game/program. Any further thoughts??

Have you got anyone who can test your graphics card on their machine?
Your card could be fried.

Wierd i have tried windows 7 on the same graphics card as you have..
The only thing is what i did when i installed W7 was rushed to the nvidia website and downloaded the latest series 7000 drivers.

The only problem i was experiencing was a verry slow FPS since 7 didnt really supported my videocard i guess. So if you want to play games with it your out of luck

I have not tried this card on another machine yet, I'll have to do that.

And yes, there is a new drive for this card for Windows 7, unfortunatly, my computer still does the same thing. And when I updated to that new driver, the computer would start, show the desktop, then flash a black screen for a second or two and then the dektop would reappear.

Well, I have figured out it is a driver problem for sure. I tried 182.5. It works except for 2 problems. It first off-sets my screen so I have to adjust the monitor to center the screen, then when I try to start flight simulator x, it has a pop up stating that it cannot run due to shader effects and video card requirements and then it is forced to exit.

Right now, I am on 178.24 and it has the same problems as before, but the screen position does turn back to normal. So we at least narrowed it down to a driver problem. It's funny how microsoft says this video card is compatible with windows 7 and that I do not need to download a driver. O well, I guess I just have to keep searching unless someone else can chime in.

Also, FYI, I have the AGP graphics card, NOT PCI, I've been reading that makes a big difference with the drivers.

I also have the exact same problem, with almost the same graphics card, namely geforce 7600 GT AGP instead of the GS version. I am running windows 7 RC.

I have the same problem, with Windows 7 only, never with an older OS. The screen looks shattered (as if the same garbage gets repeated on the screen) and the computer hangs... Did you come up with any solution?

I have GeForce 6150 integrated on the MB. Tried every driver I could...never fixedit..

Do the cards work with another system? Could be damaged hardware.

OK I solved it!! Has nothing to do with the driver. Even works with an old driver. What I did is I dropped the CPU multiplier from x11 to x10 and the problem never happened again!! So I have my CPU at 2000MHz instead of 2200MHz.

You think that makes sense? WRONG!! Read the following:
Configuration that had the problem:
CPU core clock 200MHz, multipiler x11, CPU freq 2200MHz, CPU FSB 200MHz, Hypertransport CPU 1000MHz, Hypertransport MCP 800MHz.

Dropped multiplier to x10 and fixed it. Then I overclocked the core clock to 220MHz and everything continues to work NORMALLY. So the new working configuration:
CPU core clock 220MHz, multipiler x10, CPU freq 2200MHz, CPU FSB 220MHz, Hypertransport CPU 1100MHz, Hypertransport MCP 880MHz.

1 day working fine with no crash and no shattered screen!!
Just to remind you that the problem occured only with Windows 7 and never with another OS.
