Can't run multiple apps

by pwiecek / September 15, 2007 1:53 AM PDT

When I have multiple apps open in Windows XP and try to open another, I get a message that the app can't open another window.

I'm Running:

AMD Athlon 64 X2 Dual
Core Processor 4400+
2.21 GHz, 3 GB Ram
Physical Address Extension

MS Windows XP Pro
Ver 2002

I have just recently reinstalled, but I have several utility programs running.

Any suggestions?

How many multiple apps?
by MarkFlax Forum moderator / September 15, 2007 2:13 AM PDT

You say you have multiple applications running then try to open another. How many apps, and what type?

What is the exact message, with any error code?

What prevents you from closing down some of the running applications then trying the one you want to open again?

You mention 3GB RAM and Physical Address Extension, but isn't PAE enabled to allow 32-bit Windows systems to use more than 4 GB of physical memory. I know there are other uses, but that's the primary reason isn't it? If so, enabling PAE for 3GB of memory seems a contradiction.

Also I understand, (but I am not sure), that 64-bit versions of Windows do not support PAE however I have to confess that I get confused with 32/64 bit processors and 32/64-bit Windows. So take that with a pinch of salt.

The only reason I have PAE is that it was there when I inatalled windows. I have no Idea why (or even if) I need it.

...but I can't reproduce the problem anymore. I was running Poser 7 and Photoshop 7 (This combo has worked in the past). I would get a mesage from whichever was the last to open. I also got problems from wordpad.

I reloaded the chipset driver (the Video driver had already been updated). I also reseated the videocard. (Mostly because I was trying to identify the exact model to verify I had the right drivers.

After reassembling the computer it works.

I am getting a boot message that my fan speed is too slow.

Thanks again for the help. I will post again if I start getting the messages back.

Problem is back again.

Well, my problem has returned. The system information is the same as above.

When I try to open multiple applications, I cant open more that 6 or 7 windows at a time. It happens most often when poser or photoshop 7 or both are open.

Unfortunately, I'm only getting an error sound without an error message.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
