now as a last resort I'm posting the minidump files for help. My system crashes whenever I'm watching videos online with firefox.

HELP please!

Ok I just scattered in some of those results

I'd suggeest updating all your Drivers
And using Ethernet instead of USB for network (you will need to uninstall the drivers too

oh wow! i remember. I started getting bsods when i plugged in a usb wireless card for internet. and i kept getting them even after removing it.
so the drivers are still causing the problem eh?

Well that was one of the many Bugchecks you supplied
And I'd say one of the biggest issues (if not the actual issue)

It's either that or Trend (PC-Cillin) Or both !

thanks! i'll pay attn to trend pccillin too. but the USB one is the significant change that STARTED the bsods. trend pccillin was installed in order to control the bsods but I'll keep an eye on it too.

THANKS!!!

arrgh

ACH. I got two more BSODs last night! I'm beginning to think it's my Vista Media Center that's problematic. here are the two new minidumps.

and when I restarted, I got this
SiWinAcc.sys
was either corrupted or missing, but when i chose "start with last known good", the system booted no problem and I'm using the system now.

The only constant throughout all these problems has been that I've been watching live tv via vista media center when the BSOD occurs.

Your attached 22 Bytes !!! file, does not contain any Minidump file (for 22 Bytes I'm not surprised)

im sorry. 7zip is the bane of my existence!

Inside the 2 MiniDumps:

ehrecvr.exe: process info for Media Center Receiver Service
ehshell.exe: process belonging to the Microsoft Media Center

Hmm

Possibly download the latest Windows Media Player
It could also be faulty Ram, you could try Memtest on your Ram for that
