IRQ & USB

I hope someone can solve this one for me. I have recently purchased a new 500mhz PC which has 5 USB ports, but no serial or parallel ports as I have come to know them. The PC often hangs, mostly during mouse movement, and it operates very slowly, even though it has 64mb ram. When I checked the IRQ settings as suggested to me by a tech friend, I discovered the following:
IRQ's
0 System timer
1 PC/AT Enhanced Keyboard (101/102-Key)
2 Programmable interrupt controller
3 (free)
4 (free)
5 (free)
6 (free)
7 (free)
8 System CMOS/real time clock
9 SCI IRQ used by ACPI bus
10 SiS 7001 PCI to USB Open Host Controller
10 ACPI IRQ Holder for PCI IRQ Steering
11 SiS 900 PCI Fast Ethernet Adapter(AMD)
11 ACPI IRQ Holder for PCI IRQ Steering
12 AMR Voice Modem
12 SiS 7018 PCI audio WDM driver
12 SiS960 Mulfunction device
12 ACPI IRQ Holder for PCI IRQ Steering
13 Numeric data processor
14 Primary IDE controller (dual fifo)
14 SiS 5513 Dual PCI IDE Controller
15 Secondary IDE controller (dual fifo)
15 SiS 5513 Dual PCI IDE Controller
Does this look correct? Also, in the system properties, I found this:
CONFLICTS/SHARING
IRQ 10 SiS 7001 PCI to USB Open Host Controller
IRQ 10 ACPI IRQ Holder for PCI IRQ Steering
IRQ 11 SiS 900 PCI Fast Ethernet Adapter(AMD)
IRQ 11 ACPI IRQ Holder for PCI IRQ Steering
IRQ 12 AMR Voice Modem
IRQ 12 SiS 7018 PCI audio WDM driver
IRQ 12 SiS960 Mulfunction device
IRQ 12 ACPI IRQ Holder for PCI IRQ Steering
IRQ 14 Primary IDE controller (dual fifo)
IRQ 14 SiS 5513 Dual PCI IDE Controller
IRQ 15 Secondary IDE controller (dual fifo)
IRQ 15 SiS 5513 Dual PCI IDE Controller
I hope someone can help me sort this out....thanks in advance.

Looks like you have three devices, including the PS/2 mouse, trying to use IRQ 12. Could you provide the make model of the motherboard (http://duxcw.com/digest/Fromshop/mb/det.htm) and a list of any expansion boards in the computer? Larry

Thanks Larry
Apparently there are no expansion slots (boards?). This particular PC is unlike any I have dealt with before....hence my confusion. Information about it can be found at http://www.biostar.com.cn/products/pc/easynow.htm
However, following is a pasted excerpt from the web-site......
"Instant Easy, Everything you need!
The Biostar-built EasyNow! personal computer is easier to set up, easier to use, and easier to upgrade than traditional PCs. You don't have to worry about complicated subjects like expansion slots, interrupts, or device address.
The board inside the system integrates IDE, LAN, Modem, HomePNA networking, sound and VGA accelerator. The total PC solution is provide without the need for expansion cards so there is no ISA, PCI, or AGP slots on the board. Also, many of the old legacy connectors have been removed.
There is no PS/2 keyboard port, serial port, parallel port, or joystick connectors, just simple, just easy! And everything you need."
The following is a description of the PC from the web-site of the company i purchased it from.....
"FishPC Silver 500Mhz plus Monitor 1 Only
AMD K6 II 500mhz Processors WITH 3DNOW!
64MG RAM
8.4GIG HARD DRIVE (NOT 8.4gig, but 4.2GIG)
V90 56K MODEM
24 x CDROM
15" SVGA COLOUR MONITOR
5x USB ports
SIS MOTHERBOARD
3D ACCELERATED SOUND
3D ACCELERATED VIDEO CARD WITH 24 Bit COLOUR
LAN / NETWORK CARD 10/100Base-TX Ethernet
3D SURROUND COLOUR SPEAKERS
USB KEYBOARD, MOUSE
WINDOWS 98"
I am unable to access the BIOS in the manner that I am familiar with (press DEL during boot-up). Instead, there is a file on the install cd called awdflash.exe, but I am yet to work out how to apply it. This is like learning about computers all over again....well, almost!
I hope this is enough info for you.
Thanks

Made by BIOSTAR… AMD Easynow reference platform (http://www.amd.com/products/cpg/easynow/index.html). No PS/2 mouse… It uses a USB mouse and keyboard... Awdflash.exe is used to upgrade the BIOS. The SiS960 Mulfunction device is the SiS Southbridge chip, a principle chip and the thing that controls USB, I/O, etc. It could be defective or there could be a driver problem. I can find no information or support for it. You might want to try selecting that device in the Device Manager and clicking the refresh button. It may ask for the media with the driver and I would presume that it would be on the CD (you may have to hunt for the directory containing it). Other than that, it’s not so Easynow because I can find absolutely no technical info on the computer, chipset, etc. and you, I am sorry to say, are going to have to contact the people from whence it came.
