I have a problem with my computer and I think is related to my Adaptec
SCSI controller and my memory.

Problem description:
During a back-up or restore with Central Point CP Backupwith 2.0 for
Windows, my machine freezes or the tape drive suddenly stops. Things
started after I upgraded my memory from 16 Mb to 32 Mb. Once, I was
editing a several Mb graphics file, when the status light of DAT
streamer started blinking a few times. Also, I heard the CD-ROM player
trying to start. This happened a few times while editing this file. Alle
my other devices seem to work properly. By removing 16 Mb, the hang-ups
disappeared.

Questions:
I there an address conflict between the additional memory and the SCSI
controller causing these hang-up's? Is there a way to prevent this by
configuring Win95 or my BIOS? If not, which amount of memory will not
disturb my machine?

Software: MS Windows 95.

Hardware configuration:
Vesa local bus 486/DX266 motherboard with AMI BIOS (date 06/06/1992), 
32 Mb memory, 
Adaptec Altra Line AVA-1515 SCSI controller (IQR 11, I/O port
350h-35Fh), connected to the adapter are a HP1534A 4mm DAT tapestreamer
and a Panasonic CR504B CD-ROM drive.
Tseng Lab ET4000 1 Mb videocard, 
Multi I/O controller with floppy and hard drive adapter, two 16550 COM
ports and one LPT port (standard IRQ's and I/O ports), a 14k4 external
modem connected to COM2,
2 Western Digital Caviar hard drives (no LBA or boot patches),
Creative Soundblaster 16 ASP soundcard (IRQ 5, DMA 1 and 5, I/O port
220h and 330h -MIDI-) with a joystick connected to it, 
NE2000 compatible ethernetcard (IRQ 10, I/O port 300h).
All are 16 bit ISA cards.

Can anyone help me with this problem   :-/
