CPU Usage

Sorry for another CPU post, but I've reviewed other comments and I have addressed most issues. My CPU usages maxes on viewing videos, regardless if I'm viewing them from the internet or my hard drive (not a bandwidth issue). The video becomes very jerky although the sound is smooth. It correlates very well with 100% CPU usage. Task Manager indicates that the only significant CPU user is whatever I'm using to view the video at the time. I've also had some trouble with Skype and some of the games my son plays on the internet. My question is whether increasing my RAM to 1 GB (max possible) will decrease my CPU usage. RAM usage doesn't really appear to be an issue according to what's indicated in task manager. Thanks.

Task Manager's HELP says ---
CPU Usage
In Task Manager, the percentage of time that a process used the CPU since the last update. On the Task Manager Process tab, the column heading is CPU.

Regarding any RAM you have ----
Computer Speed and Performance May Decrease

When you open, then close programs,
programs may not free up RAM memory.
That is called "Memory Leak".
Restarting computer will clear out its RAM memory.

To have more RAM available at startup,
You can do Start, then RUN, then type
Then uncheck items in the Startup tab.

To find out what each Startup(or Process) item
does or means, and any recommendation as to if you should close the process:
Task List Programs
The Process Library

You don't mention the very item that is most likely to cause video problems and that is the graphics card. A good graphics card will do a lot of the video processing itself. A crap one will off-load the processing to the CPU.

RAM and bandwidth will have little effect if the data just canno tbe processed quick enough.

Chuck and Stuart,
Thanks for your replies. I'm familiar with the issues about start-up processes. I routinely check for this and disable processes that aren't necessary. Memory leak is something I was aware of but hadn't thought of for this occasion. It's a possibility since I don't shut down my PC often. I'll test it tonight. Regarding video cards, I am not knowledgeable about them. I don't want to spend money for a high end gaming card since I don't do that. What is the criteria to use for these cards? (can you define crap?)I'm not at my home but I'd guess that my desktop has a pretty basic card. The PC is about 5 years old.

You don't need a particularly high end card to display videos properly. Your machine has an integrated video card which takes some of the main memory for its own use. Try allocating more memory to the video.

I have a Radeon 9250 with 256 Mbs of its own memory and a 400 Mhz internal clock. Old by todays standards but more than adequate for my needs. With a 1.6 Mhz CPU and 768 Mbs RAM and it displays videos with no problem.

Download and run SIW. That will show you exactly what video you have.
