My brother has a Asus P5N-D 750I motherboard. Everything worked perfect on the rig until a few months ago, where his headset - a USB Gaming Fatality headset sound goes terrible - static etc. Sometimes his mouse (razor copperhead) suddenly freezes. Now there are quite a lot of changes on his system around the time this occurred: A) He got vista. B) He upgraded his CPU from a E7200 to a Q9550. C) He upgraded from 4gb Corsair DDR2 to 6gb, getting x2 1 gb of the same ram however apparently they sent him a lower latency model. D) He updated his bios. Now, from when he's posted around he's been given feed back that his motherboard isn't good enough to run a Q9550? Apparently he's tried bumping the USB voltages in the bios etc. Does anyone know any fix? Im certain his PSU is good enough and theres no point him buying a motherboard when its not needed.. Full spec below: Q9550 P5N-D 750i Cosair 6gb 800mhz GTX 260 (not the 216 core) DVD drive 250gb Sergate HDD Coolermaster 620w modular PSU. Antec 900 stock cooling Hanns G 22" monitor. Thank you for any feedback.
could try and pop out the cmos battery for 20 minutes.. nvidia chipsets are quirky but they work if you hold your tongue just right (as mr. natural on evga forums used to say) that will get rid of any old information stored from the old bios- the clear cmos on nvidia isn't really a full clear (don't ask, I don't know why either but many have got their boards working by popping out the battery for while)
Is it just the headset and the mouse that are USB? It could be a couple of things, It could be a bandwidth problem on the bus. You can force 1.1 devices to work on the 2.0 controller by connecting them to a 2.0 hub. The other possibility I can think of that would be more likely is that it is a problem with IRQ routing. You can either try to set the USB controllers to not use an IRQ (but this may not be possible with your board), or you can try to change the routing to prevent the USB controllers from sharing their IRQ with other devices. Also, if you are using ans sort of extension cable, try connecting directly to the hub or PC instead. USB can be sensitive to cabling issues.
If it's a socket 775 it should be fine to run on that motherboard. Try resetting everything in the BIOS. playing about the voltage won't do anything good so that needs to go back to stock. Windows doesn't like hardware changes could be something like that but I'm just taking a stab here.
