One way to help determine this would be to do a selective startup in safe mode. compguystechweb.com isc-unlimited.com boot freezes sure.org.ru Symptom 7-11. The system fails to boot, freezes during boot, or freezes during operation for no apparent reason. This is the classic sign of a hardware conflict. A PC is designed with a limited number of resources (i.e. memory, I/O addresses, interrupt (IRQ) lines, DMA channels, and so on). For the PC to function properly, each device added to the system must use its OWN unique resources. For example, no two devices can use the same IRQ, DMA, or I/O resources. When such an overlap of resources occurs, the PC can easily malfunction and freeze. Unfortunately, it is virtually impossible to predict when the malfunction will occur, so a conflict can manifest itself early (any time during the boot process), or later on (after DOS is loaded) while an application is running. Resolving a conflict is not difficult, but it requires patience and attention to detail. Examine the upgrade and its adapter board and check the IRQ, DMA, and I/O address settings of other boards in the system. Make sure that the upgrade hardware is set to use resources that are NOT in use by other devices already in the system. For example, some motherboards offer built-in video controller circuits. Before another video adapter can be added to the system, the motherboard video adapter must be disabled - usually with a single motherboard jumper. Some sophisticated adapter boards (especially high-end video adapters and video capture boards) require the use of extra memory space. If memory exclusions are needed, be sure that the appropriate entries are made in CONFIG.SYS and AUTOEXEC.BAT files. If memory exclusions are not followed, multiple devices may attempt to use the same memory space and result in a conflict.
