CPU Usage 100%

[Greg VN]

Here lately my computer has become a pain to try to work in MC. Every step in the operation manager (open & close, select toolpath, backplot, etc) there is a long delay 10 seconds or more from one thing to the next.When I just open MC the task manager shows 100% usage. I notice that if I go to screen configure or the operation manager it drops down to 2 or 3%. I don't seem to have any problems in Auto Cad.

This computer came with a 40G hard drive. I added a 200G several years ago when the 40G started to get full and it was working good for a long time. About a month ago I removed the 40G because it was locking up and installed the operating system on the 200G. It worked good for a while until this problem came into play. With Hyper-threading on the usage is around 48-53%. With it off it is around 100%. The long pauses are the same either way.

I have been trying to avoid getting a new computer and have been fighting this one for a long time.

 

Anybody have any suggestions of what I might need to do to fix this?

 

Thanks

You might do a search.

 

Mastercam 9 allocates 100% but it is not actually using it if I remember correctly. This was talked about long ago though. The 100% computer usage SHOULD have nothing to do with your issues.

 

How big is the file/model?

I remember having issues like this with (at that time) large models or files with lots of toolpaths.

version 9 will always show 100% cpu usage.

Try running Ramsaver and see if that helps. The 100% is showing up because MC is doing whats called polling. It's checking to see if the mouse,keyboard,video card etc. are still there and ready. It's a DOS legacy thing. Other than that I would run defragmenter regularly to maintain optimal performance.

I defragged yesterday and when I ran analyze it said it did not need defragging but I did it anyway. I had this slow issue for a while and I thought that it was because of the large files that I was working in. It still has the same problem in small files.

 

Thanks for the input.

I had this same problem, however I was getting processing issues on everything, not just mastercam. Is your computer accessing the hardrive for long periods of time?

Defragging, deep hardware scans etc. showed no problems, and I was just about ready to get a new hard drive before I backed up, reinstalled windows and everything was fine. I guess just some core was corrupt in sectors and while looked fine, had trouble initializing some read/write

I decided to get a new Dell and just placed a order. The new one is not the fastest and baddest out there but it should be better than what I have been fighting with.

Thanks for the help.
