Hi all, Yesterday my neighbour bought a new pc which has a A7N8X-X motherboard. http://usa.asus.com/products/mb/socketa/a7n8x-x/overview.htm He also has a ATI Radeon 9800 SE video card and 512 Mb DDR Ram. He is using the onboard audio. He called me over because he said that the sound was "jerky" so I checked it out and both the sound and video was jerky indeed...and as well the mouse was not very responsive. I went to the ATI website and downloaded the latest Catalyst Drivers and installed them. Upon rebooting his system instantly improved in all of the above areas. Today he told me that it ran fine for about an hour and then the problem returned. When he reboots it's fine again for about 1 hour. I'm going over tonight to take a look at it again but I thought I'd throw this info out to see if this may sound like anything obvious to you guys. Any suggestions based on what I've told you? Thanks Gary

Hi Gary. Maybe it's a heat issue. After an hour of operation the heat buildup from the video card and other components may be building up causing the problem. Open the case and run the computer with the case cover off. See if it will go for more than an hour without problems. If it turns out to be a heat problem, install an extra fan or two. Take care, Linda

Gary, did you delete the old drivers before installing the new? That's important, you probably did but I'd thought I would mention it. Also make sure you are running DirectX9. I also strongly suggest that you disable the Windows fast-Search indexer;I have actually seen that thing interfere with video and games when it kicks in to do it's update thing. And it does it at least once a minute.

Hi, I suspect you have a memory leakage problem A running program is not releasing memory back to Windows and you are slowly running out of resources. It will not be a heat issue as a quick reboot would not reduce the amount of heat inside the box. Solutions 1 Try changing your Hardware Acceleration slide left one position and see if that works. http://mirror.ati.com/support/faq/winxp/winxpconfigadjusthardwareaccelslider.html 2 Stop each running task one by one until you find out which one is casuing the problem. I had a similar problem with a four hour 20 minute time some years ago. This was caused by a conflict between two running programs . Each company blamed the other. It took Dell and Microsoft 3 months and some 33 different things before it was traced. Solution was to leave a tick box ticked out. hth Ceri

Before opening PC.....make sure there is no sticker in the back of it. If the sticker is broken the warranty is VOID! I am saying this because you said this is a brand new manchine. Robert
