a couple of nights ago i decided it was time to do a reformat and fresh install, it had been 4 years since i had last done that and my shutdowns/reboots were taking about 7 minutes. i reinstalled my OS- WinXP, downloaded all of the windows updates, added my programs and completed a virus scan. so far so good. fast boot up and shutdowns. no issues with internet surfing, watching movies or listening to music, burning, or uploading.
however, i began to experience odd freezes while downloading from usenet. my pc will freeze for about 15 seconds and then unfreeze for about 10 seconds, and then refreeze. and it will continue like that until i close the program down and stop downloading. once stopped i do not experience any freezing issues.
i am at a loss as to why this is happening. prior to the windows reinstall i was experiencing slow shutdown/reboots, but had no freezing issues even while downloading. i have run a scan using hd tune and it reports my hard drive being healthy. what else can i try to fix this?
