so im looking for a new computer for my sister and we found a nice windows vist for
175 $ works very nice but my sister likes to watch videos and stuff so we just wanted to see if it worked on the vista. We went to fox.com and tryed to watch a video it wanted us to install a plug in (move medio player) so we could watch it and we did... then when it started loading the video, somthing popped up and said the plug in was doing somthing illegal and BLAH blah and then it shut down... we disabled the firewall and it still did it yet when i do it on the computer i am typing on right now it works fine on the only difference is its WIN 2k not vista


does anyone know how to fix this problem??
    PLEASE help

thanks in advanceblah blah error message won't help to help you. Post exact error message, plug-in name, and computer specs.uh OK sorry for that part... lol i don't have the computer at my house atm because he haven't got it yet so im not sure what the exact message was but it was like "error this plug in is doing something illegal and we suggests you shut it down" then a box pops up and says "fire fox is closing down" with a little loading bar then firefox closes out
we tryed it with abc.com and some other site but it does the same thing

the info for the computer is...

AMD Sempron 3200 + CPU
512 MB DDR2-533
80 GB Hard Drive
10/100 fast ethernet network
56k modem
DVD/CD RW combo
6 usb 2.0 ports
Windows Vista Bacic
Open PCI-Ex16 slot
Couple of things I'd do.
Since it's used computer, I'd reformat it, and reinstall Windows.
Secondly, 512MB of RAM won't work well with Vista. You either upgrade it to 2GB of RAM, if you want to stick with Vista, or install different kind of Windows, preferably Windows 2000. If you want to put XP on it, you want to have 1GB of RAM. Other specs look OK.Ok thank you for the info, now we are sure we wont buy it... tehe 
we will just keep looking.
