Got a real brain buster for you all. I recently completed building my first computer (spec's to follow). The problem I am having is that it will lock up at various time through out the day. It will lockup anywhere from 1 to 5 or 6 time a day. While surfing, playing games, even at the desktop. I have uninstalled my anti-virus software (Inoculate-it PE), updated to the latest video drivers (both Elsa and nVidia reference), updated my VIA drivers (4-1), replaced the stock cpu cooler with a Global Win WBK38 Super (my cpu temp according to mobo utility is from 44 C to 56 C). I am not running a screensaver or any power saving settings, it is set to be on all the time. I am also running MS Internet Connection Sharing software to network 2 other computers thru a hub. This computer is the server for my network. The following is a report showing my IRQ settings: Hardware IRQ Settings >>> ----------------------------------------------------------------------------------------------- 0: System timer 1: Standard 101/102-Key or Microsoft Natural Keyboard 2: Programmable interrupt controller 3: Communications Port (COM2) 4: Communications Port (COM1) 5: Creative SB16 Emulation Status: This device has been disabled. 6: Standard Floppy Disk Controller 7: ECP Printer Port (LPT1) 8: System CMOS/real time clock 9: ACPI IRQ Holder for PCI IRQ Steering 9: NetSurf 10/100M LAN Card 10: ACPI IRQ Holder for PCI IRQ Steering 10: Creative SB Live! series 10: VIA Tech 3038 PCI to USB Universal Host Controller 10: VIA Tech 3038 PCI to USB Universal Host Controller 11: ACPI IRQ Holder for PCI IRQ Steering 11: NVIDIA GeForce2 MX 11: Realtek RTL8029(AS) PCI Ethernet NIC 11: SCI IRQ used by ACPI bus 12: Microsoft PS/2 Port Mouse 13: Numeric data processor 14: Primary IDE controller (dual fifo) 14: VIA Bus Master PCI IDE Controller 15: Secondary IDE controller (dual fifo) 15: VIA Bus Master PCI IDE Controller I am at my wits end trying to figure this out. Any help would be greatly appreciated.
