I've got a Thinkpad T43 that has been acting up recently and I can't figure out what the hell is going on. It all started when I tried to watch a video that I downloaded from my camera. I've watched several videos in their native whore bastard format (MPEG-2) without issue. This time though, it was choppy and stalled in a few spots. It was like it ran out of memory or something. So, I checked the performance of the computer using the Ctrl + Alt + Del keys and swapping tabs and the top graph spikes irradically (I dont remember this happening). Is that normal? So, I went out and bought some RAM today PC2-5300 1GBX2 and installed. Worked fine, recognized by windows, yada yada yada... I was hoping that I would have my problem fixed... Nope. It is better, but not nearly as smooth as it used to be. Keep in mind I've already used AVG free Virus, and Spyware checkers along with Spybot and AdAware to test my system for misc shit. Nothing comes up except a couple tracking cookies in AVG Spyware... and it fixes them. Also, I have McAffy VirusScan that runs all the time.. My system stats are: Intel Centrino 1.86GHz 2GB RAM 40 GB HDD in 2 partitions (C:System = 20GB, Data=20GB) - C: has 11 free GB and D: has 9 free GB OS is XP pro I dont know of any programs that I've installed lately to instigate this problem.. I haven't installed anything in a while, and it hasn't been happening that long. Also, I ran a Disk Check and it took almost TWO HOURS to run its course. I scanned after a restart so it scanned before the OS kicked in. Is that normal? Thanks for the help in advance.
