Dell Inspiron 1721; Vista; Service Pack 1 regularly updated; AMD Athlon 64X2 Dual Core Processor, 1.9 GHz; 3 GB RAM; 250 GB HDD with 137 GB free space. Using AVG paid subscription with current updates; SuperAntiSpyware paid subscription with current updates; SpywareBlaster, also updated regularly; and Ad-Aware Plus, also updated. SuperAntiSpyware found a trojan last week, but said it fixed it, so that's probably not a problem.
It has been fine until today except that the playback on sound and video that are on the HDD or onlie have been hanging up for some reason that I haven't figured out and a notice every day or so that the network controller has stopped working, but Windows can't fix it - - it always starts up again right away. Today, as music was playing, the computer hung up and began beeping loudly with the music skipping sort of like a bad CD would - - but the music was on the HDD not a CD. Then the blue screen - - and that hung up - - and I had to turn off the unit manually. It has seemed a bit slower today than usual, but that's the only other sign of trouble before the crash.
Any suggestions or advice? The computer is still under warranty, but just thought to check if it might be something simple I could fix before calling Dell and shipping it off. The only thing different today is that I installed itunes and Quicktime yesterday. Nothing else has changed recently. Before going to sleep, I am going to uninstall itunes and delete the hundreds of music files in copied and converted from my mp3 files yesterday, using up A LOT of space.
Thanks!
