| Ok Lately I've noticed a significant decrease in my computers performance (i.e I used to be able to watch Divx movies on the highest quality settings, but now they are extremly choppy at even the lowest setting)so I opened up task manager and found that the cpu monitor had two different graphs; a red one and a green one. Im pretty sure that the red graph means that something is wrong, but I dont know what! I searched technet but I havent been able to find anything yet so I was wondering if someone here could tell me what that red graph means! thanks. | |

The red one tells you privileged processor time which roughly means the operating system kernel. You should always expect to see som red activity. Use performance monitor for a more detailed view at processor activity.

| Thanks! I just found out that I had the 'show kernel times' option checked...hehe. well now I just have to find out why those divx movies are playing so badly... | |

| How much memory does your pc have. sounds like something is hogging the memory or cpu. Go to Task Mgr and see what prog is hogging processing time.

| I have 512 mb of ram. I was checked task manager wile I had a divx running and windows media player was using about 97-98 percent of the cpu. I still cant figure this problem out! | |

| Try defrag'ing the disk. Sounds like the disk is working harder to find the next sector while reading.
Just a thought.
btw, in my experience, NTFS defrags almost as quickly as FAT. | |

| Disk defragmentation does not add much to the CPU usage. In fact, a fragmented disk and a disk intentisve application will make the processor spend more time waiting for the disk to finish its operations thereby decreasing CPU load.

| Try to unload some of the unnecessary process.I would also re-assign the priority of other system process`s. This is a good way to tune your system. | |

| I beg to differ here. While your statement if somewhat correct, if a disk is severly fragmented, it can only be hindered as it locates available sectors in which to write (or read) the data.
And as the question was geared towards watching DIVX films, this to me sounds like a data throughput issue as the disk cannot keep up.
Just my 0.02

| try terminating some services not in use.

Good! Makes for educational discussion.

That's true. A fragmented disk will (generally):
1) Delay process execution since we have to wait longer for the disk to do its things
2) Add a minute amount to the total CPU processing needed, because the disk driver will have to issue more transfer requests.
3) Increase processor idle time as a direct result of 1)

I noted frockenshnit mention that 97-98% of CPU time was spent in one single process, one that is crucial to the playing of the films. I therefore conclude that this is the bottleneck, not disk waiting. The proper follow-up would be to find out excactly why this happens.
To comment on slapyomomas post: since that much of CPU time is spent on a relevant process, terminating other services is not likely to make a significant difference.
