hardware question
Should there be two things using the same IRQ?
I have NEC PCI to USB Open Host Controller and Radeon 9700 Pro both on (PCI)19. I also have NVIDIA(R) nForce(TM) Audio Codec Interface and Standard OpenHCD USB Host Controller both on (PCI)21. Will this cause problems? The reason i ask is this.. I had a razer diamondback mouse that would disconnect from usb, and connect again by itself, constantly. so, i'd be playing a game, and my mouse all the sudden dies completely, for a few seconds until it connects itself again. it only seems to happen when i'm playing games so far. i thought it was the hardware(razer mouse), but now i have an old logitech usb mouse hooked up and it's doing it too. I have reformatted and reinstalled windows fresh. It didn't fix the problem. Could the IRQ thing be the problem? Or, is my USB hardware failing on me? I haven't had problems with any other USB item other than my mouse. the damn mouse... it's crippling as far as playing games. |

However, it is not a good idea for the video card to share an IRQ. If you must share, then get the card to share an IRQ with a device seldom in use or with low usage. Your current arraignment where the USB mouse shares with the video card and the audio card also shares an IRQ is about the worst you could do. Your mileage will vary and will be best with WinXP but I strongly suggest changing card slots or reserving IRQs in the BIOS. What will be possible for you will depend on your motherboard and BIOS. |

It would be ideal for everything to be on its own IRQ, but in cases like this where onboard devices are sharing there is often nothing that can be done about it. In any case it should not cause problems like this. Much more likely that you have a bad mouse.. could be the cable is broken internally. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from Home Page: http://www.roberthancock.com/ |

The most unsolvable problem i have had yet with a computer since 1997. It feels good to have it taken care of... Thanks for all the help!! It was an IRQ problem i assume, because i had a USB card in there, and just switched PCI slots. I also disabled serial ports and one other thing i believe. I was having problems with both the logitech and the razer mouse. So far, after a whole night of gaming, i have had problems with neither, and so i have my Razer on here again. |
