Amazing problem!
I have win2000 professional on PC.Since the m/c starts booting -restarting in between my work,so I have formated my PC and put win 98 operating system.Actual problem starts from here.

Now my Photoshop dosn't work.Means it get shut down after giving error message in between ,some time after 10-15 minutes some time I can work for 2-3 hrs.

I have tried everything....reformated PC,Put different version 6/7 from different differen set ups(CD),then put only Photoshop and removed other graphic software,Upgraded my Ram,every possible thing I did.

But the problem remains unsolved.Only change I observed is when I have upgraded my ram to 192MB,I could use PHotoshop 4-5 hrs continueously and I need not have to restart my PC as I used to do earlier.

What could be the problem & what could be the solution??

Please help!!!

What is the error message?

How much RAM on the system?

How big is your Vitual Memory?

What CPU?

I have 192MB Ram.

My processor is Pentium III

The error is - Illigal operation and programme will be shutdown.
(Some what like this)

I am using this system for last 4 yrs with same configurations, rather earlier I have 128MB ram, but I have never faced such problem.

With same configuration I have used PHotoshop on Win2000 & Win 98 also.Now I have Win98 on my PC.

What is your Virtual Memory setting?

I can see were you are coming from, photoshop uses a lot of memory resouces.

http://www.flawebdeb.com/photoshop.htm Some good reading and tips.

How Photoshop Uses Memory
When an image is opened in Photoshop, the program requires about 50MB of memory plus an amount roughly equal to the file size of the image. For example, to open a 100MB file in Photoshop, you will need a little over 150MB available memory.

Any tasks you perform in Photoshop increase the amount of memory required by the program. Rotating an image consumes about three times the amount of memory that opening a file does – rotating a 100MB file requires over 300MB of memory! Most other tasks require less memory, but features like the History Palette add to the total.

Photoshop can use your computer’s hard disk as temporary memory space when you run out of real, or physical memory. This is called using the scratch disk. A scratch disk is a convenient way to bridge the gap when the amount of memory Photoshop needs is greater than the amount of memory you have installed. The problem with this approach is that even the fastest hard disks are very slow compared to Random Access Memory, or RAM.

RAM can store and retrieve information about six to twelve thousand times faster than accessing the same information on a hard disk. When Photoshop has to use the scratch disk, tasks take much longer to complete. This means that even a faster processor or new computer provides very little benefit over an older system, unless you’ve got enough memory to handle complex imaging tasks.

I created a simple test to illustrate how vital it is to have enough RAM for Photoshop. The results (which you can see in the chart below) are quite dramatic, and show that for a particular operation, Photoshop may need over 800% more time to perform a task once free memory is used up and the scratch disk is used.

I have checked my virtual memory settings.

I have not done any memory settings .The otion I have selected is le windows will automatically set the virtual memory settings.

Also I have chaeked the resourses used by clicking performance tab...it shows 85% resourses are been used..

Are they sufficient...does the above things signifies anything
