DSP builder jammed

Following is my machine spec:

AMD Athlon(tm) 64x2 Dual

Core Processor 5600+

2.80 GHz, 1.00GB of Ram

Physical Address Extension

and also following is the software that i installed:

Matlab 2006a

Quartus II 7.2sp3

Quartus II Dsp Builder 7.2sp3

i wonder could it be the version of those software are not compatible to each other or perhaps not compatible to my machine spec?

I have used DSP Builder without problems in Matlab r2007b. it's the only way i see, cause your machine has just the necessary resources.

so you are using the Quartus II 7.2sp3 and DSP Builder II 7.2sp3 as well?

i do believe is the matlab not compatible. so if it possible if i use matlab 2007a? i think i only have installer for 2006a and 2007a.

by the way, if i were to change my matlab, can i just uninstall the old one and install the new one. will this give any problem?

DSP Builder 7.2 is compatible with MATLAB 2006a. Your problem is unlikely to be due to your MATLAB version.

so what should i do?? could it be my window or other setting??

When your system becomes jammed, are there any processes using CPU time?

(Press Ctrl+Alt-Del and select Task Manager, click on the processes tab and click twice on the CPU heading so it sorts tasks by CPU usage.)

Are any processes apart System Idle Process using much processor time?
