Computer lag/glitch? virus?
I am running win2k sp4 w/ all windows updates and 512ram with a 3.14ghz celeron chip. I just installed a new AGP ATI all in wonder 256MB graphics card to support my new wide lcd monitor. Prior to any system changes (about 2 wks ago?) I could watch .avi and .mpg files without any problems, however recently every time i attempt to watch one, the sound cuts out in awful ways and the video at times will lag for a second or two frequently. I assumed I had picked something up, as i was browsing astalavista for a serial, so i ran every check i could think of and removed some low risk spy/adware. this didnt fix my problem though. so i updated all the drivers for: the graphics card, the sound card, and i even flashed the bios to the newest update. i have uninstalled and reinstalled drivers and devices and i have used the following programs to scan all my disks: ad aware, spybot s&d, kaspersky, avg, clamwin, and i have also used CleanUp!, hijack this, and stinger. i am out of ideas.
is this a virus? i use VLC but when VLC doesnt work, i use the ati file reader which at times seems to play the files with only slight video errors, and someimes nero showtime to the same effect, but i really would like to have my computer working properly again! does anyone have any suggestions? has anyone ever had this happen before? this might belong in the software forum, but i’m not sure so i placed it here. thank you so much for your help, i appreciate it.
oh ps. i am looking into upgrading ram but it is crazy expensive… could this be a ram issue, even though it worked fine before on just 512?
thanks!
