Help me please

Hi, I just installed Win 7 on my PC, and I have an Saphire Ati Radeon X1550 series graphics card, I'm experimenting some problems when I run a 3D aplication like a video game for example. The problem is present when I run visualizations on WMP or in the winamp.

The problem manifest itself from the following way:

When I'm playing a videogame: The screen starts to blink and to twinkle, the the figures start to randomly change and some kind of black stripes randomly appear all over the screen, the the screen stays in black and the sound stays wedged and then the OS get into a crash.

When I'm on the Windows's Desktop or using winamp or WMP: The screen puts black and comes back again, an alert message appears specifying that The Video controller has stopped from working but that has been reactivated.

I have determinatted that this issue coul be some graphic card's driver malfunction. So if someone can help me suggesting me the drivers and applications that I have to download and where DL them I'll be very glad.

Thanks so much

mmm that would be possible till monday, because i'mon my work, and I don't have the info in here, besides I don't have internet connection in my house, but I'll check it out and post it on monday.

thx so much

The device specification of my video drivers says that it works correctly, but, as always, when there is any problem, your device manager won't show the real status of your hardware. But, I got sick of trying solutions, I've downloaded drivers for win 7 from many websites and the problem persists...

I had this problem for the longest time when my 8800GT 1gb became a year old.
I tryed EVERYTHINGG.. it mostly happened with counter strike source at first, then began to happen with every game I played. The error is random and never consistent, you get a sound loop with a crash for 20seconds-2mins depending on the severity of the crash.
I did everything in the world to try and fix this, formatted, got windows 7 (Problem was worse with XP) replaced my hard drive thinking there was something wrong with that, but no nothing worked, even updating or downgrading the drivers didnt work. Ultimately at the end I found out that the graphic card had a problem within itself and it did indeed malfunction. I just RMA'd the part through EVGA (Thank goodness for their life time warranty.) So what I recommend is you try doing the following, borrow a video card from a friend and run your game for hours to test it (Even leave it on and just stay idle if you have to.) if at anytime you see the error, then you know its not the graphic card and it could be something else. Even memory issues can cause this problem, but I was able to isolate that it was my graphic card using this method.

Worst come scenario (Which is the most obvious and probable.) is that you buy a new graphic card. I would say its time to upgrade anyways :)

Another possible problem I forgot to mention, and its a relatively simple fix this may or may not work but it should be the first thing you do for trouble shooting. Flash your bios to the latest update, some motherboards have problems with newer PCI-E x16 graphic cards with their large 1gb GPU and/or their power outputs so the MB drivers need to be updated. This method actually fixed my brothers problem when he had this issue with his ASUS P5k-e and 8800gt 1gb. If it helps any, this problem is pretty common with ASUS motherboards for some odd reason, so a driver fix may help. Give it a shot, if that doesnt work try the method I mentioned above.

I had a 220GT that did that playing games. At one point I could hear the fan buzzing and realized it was overheating. I ended up replacing it. The new one has been working fine now for months. I don't think its a driver problem sounds more like a hardware failure.

Ok thanks so much for your helping and opinions... but I know this definetively is not a hardware problem, because I uninstalled the ATI drivers and installd the mainboard integrated graphics adapter and the problem was the same... this is happening since the day I installed Windows Seven... I had the mighty and powerfull Windows XP and everything was working good, but that day I installed W 7 everything turned black for my PC... I even tried with RAM memory of a friend of mine and the problem persisted... so.. bye bye win 7 nice 2 meet ya but... I will come back to XP really when Microsoft realeases the 1st or 2nd service pack I'll try again Win 7... meanwhile I will bet on the compatibility of win XP.

Thanks Guys
=)
