im running Windows XP Pro SP1...I have an agp tnt2 32mb, a d-link nic card, sounblaster sound card, an elitegroup mobo with athlon 1ghz, 392mb sdram....i had no problems with freezing until i installed a pci all in wonder 128 16mb...then i would have freezing after about 15 minutes when using that card, or when i was using my agp card i would have random freezing. I use Snapstream for capturing, and would have constant freezing when that was recording, or any or kind of caputring software such as Win VCr and a few others. I then bought a wintv pci card and reformated. I still have the same problems...not quite as often but often though. When snapstream is used i get freezing, or if im doing something that might cause the cpu to work, such as rendering mpg files, some certian games also cause my machine to freeze. I also get random freezes when doing the normal Pc stuff like surfing, listening to music, etc. is there anyone else that can relate to my problem and if so, is there anyway to correct this. I'm not running any antivirus in the background. I have all the latest drivers for my hardware. When I check the event viewer, I notice the acpi and service control manager errors around when the time i get the freezing. if there is anyone else that is sharing this problem you know how annoying and frustrating this is...thanks..
