My motherboard doesn't have firewire, and for the life of me i can't find a single expansion card that has an internal pinout that I can connect the cable for my front firewire port to. The closest I found was not low-profile compatible.and this is for the computer in my description, but on monday I'm switching out the case for a low profile hec 7K09 HTPC case.

I recently got a new power supply and video card for my computer. It has been working great but on accident one day I broke the plastic divider inside one of my usb ports so that one no longer worked and now my other usb port is not working. It will not recognize anything plugged into it and my phone can't even charge through it. It did the same thing a few days ago but it randomly started working again but now it isn't and I don't know how to get it back or make it stop. The usb ports on the back of the pc are still working though, my keyboard and mouse are plugged in through it and haven't stopped working once.

I have this motherboard. and get no audio when I plug in headphones in the front or back ports. I'm running win 7 so there aren't compatible drivers available on asus site, I tried downloading the vista x64 and installing them in compatibility mode but the device manager shows "High Definition Audio Device" so I think it's still using a generic windows driver.
Also tried these: Realtek
Sound>Playback shows Digital Audio (S/PDIF) and sound bars move while playing a mp3 or movie but still no audio. Usually speakers and headphones show up I though? I don't even see them when I choose show disabled devices. I tested usb headphones and got audio but I really need those 3.5 jacks to work.
The audio on this board is: Realtek ALC662, 6-CH High-Definition Audio CODEC
I've also reset the bios, and the mic shows up and receives data when plugged in but still no sound.

I've been hosting servers on various videogames over the year to play with my friends online, recently I tried a game which worked about a month or so ago (mount and blade: warband, I also tried a few others afterwards) but nobody could connect, I checked everything and it should have been working fine but then I looked at various port checking websites and for some reason none of the ports are open anymore.
I've tried changing the port settings, resetting the router and disabling my firewall and none of them seem to work.

Certain devices ("obsolete" flash drives, iPod) are undetected in Windows 7. There are no problems with my mouse and wireless adapter, which are USB. I have tried connecting previously undetected devices through the same ports that detect the mouse and wireless adapter, which has made me further suspect the problem being with the ports, thus possibly drivers, rather than the devices (since the devices are still undetected).
I have also tried uninstalling all USB ports in Device Manager before restarting Windows, which didn't help.
Another related concern is whether the motherboard driver(s) is(are) up-to-date. I have an Intel Desktop Board LGA775 and cannot find the proper download for an update. This may fix the problem.
Suggestions?

When i try to connect my wireless mouse to my laptop it dosnt respond at all. It says it is connected, however nothing works. Ive tried using a Flashdrive and it works fine. Ive also tried with 3 different mice with the same result. Im guessing it has to do with a driver i have recently downloaded from windows update, however, i have restored my computer as far back as i can go, and it still dosnt work.

I was away on a trip, so I let my parents use my laptop while I was gone. They say it updated, something, but afterwards froze, so they turned it off. Turns out it was several different updates, including a BIOS update. Everything else works fine except for my usb ports which no longer detect anything connected to them. The device manager gives me little yellow warning bubbles by Standard Enhanced PCI to USB Host Controller and Standard OpenHCD USB Host Controller. It says code 19 error and the config info in the registry is missing or damaged. I have tried updating the drivers, uninstalling and letting it re-install, but it hasn't worked. I'm running on a HP Pavilion dv6-3013cl Entertainment notebook, Windows 7 (64bit).

I have Logitech Performance MX mouse. It used to work fine until somebody installed other mouse on my computer. Since then mouse was randomly disconnectign and reconnecting every minute.I managed to fix that now mouse is stabile but even though all drivers are installed it is seen as HID mouse and not my Performance mouse - so i cannot for example see its level of batter load.The other problem is there is loads of extra identified USB controlers and mouses even tho i have just connected 1 mouse, 1 keyboard by other USB port + 1 external HDD. Thats just 3 USB slots total.If i put pendrive into computer, then mouse keeps disconnecting againIf i turn on 'shield scannign devices' then after puttign USB into drive i have 3 seconds to click 'not scan it' if i do that, it wont be disconnecting. Yet turning off scanning makes mouse disconnecting on putting extra pendrives.Here is what i tried so far:@ USB Driver - General Fix for@ Turning off windows shell scan [to not auto scan devices].@ Chaning ports, upgrading bios etc.@ RUnning windows 7 USB problem fixer. It is turning off

Anything that I plug into the usb ports isn't recognized on my computer. When I plug something in, my computer doesn't make the usual "bloomp" sound and nothing pops up. When I search for my usb in my computer, it's not there. My computer acts like I didn't plug anything in.

I turned off my computer for the night and the next morning when i went to turn on my computer, none of my usb 2.0 devices (mouse, wireless adapter, etc.) worked. The only thing that does work is my keyboard and its a PS/2 keyboard.

I am running an HP Compaq 8510w with Windows 7 Enteprise. When I first got the laptop the USB ports didn't recognise devices when they were plugged in, and the laptop would just hang when shutting down (on the Windows Shutting Down screen), so I decided to reinstall the OS as there was a lot of unnecessary applications installed.
I've been using the laptop since the rebuild and all has been good, until the past week or so when the same two problems have materialised again - when I attach a PSP, or a printer via USB, they are not recognised. And when I shut the laptop down, it hangs on the Shutting Down screen.
What checks can I run to see what the cause of this might be? I've not really installed a load of software on here, and I can't think of anything specific that I may have done that would cause this...

There are several problems with HP Mini netbook. First among them is that programs keep freezing. It seems to start up normally, but shortly after you launch any program (even explorer or the control panel), it hangs. This means among other things that I can't get into Device Manager to look at things like drivers because I can't get there before the freeze sets in. When it happens I can still get to the toolbar and use the start menu and so on, but if I try to launch any other programs, nothing happens. Also I can't force the shutdown of the "hung" programs.
I figured this sounded like a Class A virus situation, so I tried to download some tools like AVG. The Freeze got me, using both IE and Chrome. I tried loading up my USB Thumbdrive (full of troubleshooting tools). The HP won't admit that it even exists, and the access light on the stick never blinks. An external USB HDD available, so I hooked it up. Again, not even rejected, just ignored. The HP will recognize an external DVD drive, but refuses to let me write anything to a black disc. In fact when I try the drive disappears altogether.

I have a Del 1600N Multi function printer that has been in use (successfully) for about two years on my home network. The printer has a built in NIC and is connected via a dedicated 10BaseT line to my network. This printer was working just FINE until I decided to use it as a fax. Some how during that process I must have cleared the network configuration and it stopped being visible on my network. After some investigation into this I was able to get it back on the network my manually assigning it an IP address. Using the supplied installation DVD, I was able to install the printer onto my two desktop computers (running XP Pro 32 bit) and it works just as well as before.
The problem occurs with my wife's Dell laptop. Before the great "fax fiasco" (as I like to call my stupid attempt to use this printer as a fax machine), the laptop was able to find and print to this printer with very little problems. Now, not so much! When I went to re-install this printer the first time I made sure that the Dell Printer software was uninstalled (via Control Panel--Uninstall Programs). The first attempt seemed to be going fine. The software detected the printer on the network and it looked like a successful install. However, the test page did not print out! I checked in the "Printer Properties" to make sure that the printer was on line and sure enough, it was.
But there was a troubleshooting alert that told me the document didn't print. After several hours of messing with it, I decided to uninstall and try again. The second time went much like the first. Then I reasoned that the drivers may be the problem. So I looked on Dell's web site and found the Windows 7 drivers for this printer. I uninstalled the old drivers, downloaded the new ones and then installed. As before it found the printer. But during the install it flashed a message saying that it could not find a file (which was weird).
When I hit "continue" it proceeds and looks like it finishes. The network printer monitoring icon appears in the system tray and I can see the 'scanner" portion of this Multifunction Printer. But still, it won't print to it. And in addition, the printer now refuses to show up in the "Printer and Devices Window"! What am I doing wrong? I've heard that Windows 7 has problems with old printers. But this printer was working perfectly before this! What steps do I need to do to totally remove the old printer drivers and start from scratch? Is there a way to get this printer to be able to work with my wife's Dell Laptop?

Synopsis: PSU died, replaced PSU with different model, system boots to bios successfully but does not recognize any devices in SATA ports, nor do those devices appear to be getting power. Now can't even get to BIOS, entire PC flicks on and off repeatedly as soon as I turn the PSU on regardless of whether I hit the power button on the front of the computer.
System Specifications
Original PSU that died: SeaSonic M12II 750 SS-750AM 750w PSU
CPU: Intel Core i5-3570K Ivy Bridge 3.4GHz
GPUs: ASUS 670 non-top version, SLI (2x)
MOBO: ASRock Z77 extreme 6
RAM: Mushkin Enhanced Blackline 8GB (2 x 4GB) SDRAM DDR3 2133
Optical drive: Sony AD-7280S-0B 24x SATA Internal DVD+/-RW Drive
SSD: SanDisk Extreme 240GB SATA 6.0 Gb-s 2.5-Inch (OS is installed here)
Storage drive: Western Digital Caviar Black 1 TB SATA III (This was not connected when power supply died)
Detailed explanation:About a week ago my PSU (Seasonic 750w) died randomly while the computer was left running in sleep . I RMA'd the dead seasonic. In the mean time I happened to come accross an extremely good deal on a new PSU, so I bought it (Thermaltake smart m850w PSU) to have a backup and to get my machine working again. I hooked up the new PSU to GPUs, CPU, fans, ATX power connector, and to all of the SATA devices, (the SSD, the HDD, and the Optical drive). I made sure to connect the data cables to the SATA devices in the same configuration they were in when working properly. The computer boots successfully to the ASROCK BIOS, all fans spinning. However, I get the error code "A6" on "dr debug" (the led display on the mobo). The manual says this means "SCSI detect". I have no idea what that means.
I was able to load the UEFI, and bios recognized all components except for any of the SATA devices--(SSD, the HDD, and optical drive not recognized). The RAM, GPUs, processor, and fans were detected. At this point I was stuck in BIOS because I couldn't boot off anything.I did not have the HDD connected when the PSU failed, but now the BIOS won't read that either. I don't think any of the SATA devices are actually receiving power. Again, the UEFI showed that there were no SATA devices connected to any port, when in reality they clearly were connected both by power and data cable. Then things get really strange. I unhooked all of the SATA devices except the HDD (the one that wasn't hooked up when the original PSU died). I plug the AC into the PSU, then turn on PSU (not the power switch for the computer, the switch on the PSU). The computer starts flicking on and off in this weird rhythmic pulsating pattern "click...click...click...click..." with about a 1/2 second between each click. Each time the power flicks on, the LEDs come on and the fans spin briefly. The strangest part is that I don't need to hit the power button on the front of the case for this to happen, it just starts as soon as the PSU is turned on. In fact, I can't get the computer to turn on at all--the switch on the front of the computer appears to be dead.
1. Unplug the power cables from everything and re-seated them.
2. Reseated the data cables to the optical drive and the SSD on the drive end, not on the MOBO side as they are covered by my GPUs and I would have to take them out in order to do that.
3. Tried hooking up a SATA power cable from my old modular PSU and using that in the new PSU in an attempt to power the optical drive (didn't work, I know, bad idea--I learned you aren't supposed to do this shortly after I tried it)
4. Setting all preferences to default in the UEFI.
5. Disconnecting the power cables from one or both of the GPUs.
I think that this is either a problem with (1) the motherboard, (2) the new PSU, (3) all 3 SATA devices (unlikely). The fact that I can't even get into Bios anymore tells me that this may be a MOBO or PSU issue.My main question is how to procede from here? I suppose I can wait for my Seasonic to come back from RMA--perhaps that will clear up the issue. I just can't shake the feeling that this is a MOBO issue though. I am worried that if I keep screwing around with it I may end up frying my CPU and GPUs. I can eat the cost of a MOBO or PSU if necessary, but I can't afford to buy a new processor and two new 670s.

I recently updated my Windows 7 Ultimate with Service Pack 1 through Windows Update and after the reboot my Bluetooth devices don�t work. I have two Dell mice and a Dell keyboard and they no longer function.I deleted the devices and added them back and while they were discovered and did attach they don�t function. Additionally, detailed information on the devices is no longer present.One of my mice was a Dell Travel Mouse and before it showed up as an icon that looked just like my mouse not it shows up as a generic mouse.
In trying to troubleshoot this i disabled the internal Bluetooth and plugged in a Belkin Bluetooth Dongle and it behaves the same way. However as this was an external device it has a flashing light showing when it is receiving a transmission and when I moved the mouse the light would flash so the signal is getting to the computer however nothing is happening on screen. This dongle works perfect on my other Dell D620 Laptop with Windows 7 and no service pack.

A few days ago I installed a USB 3.0 card (to be precise, this one: 2-Port USB 3.0 SuperSpeed PCI-E Controller Card - Free Shipping - DealExtreme). It uses the very common NEC PD720200 USB 3.0 controller. I installed the required drivers for Windows 7, and the card worked fine for the first day or so. but not since. Whenever I plug in a USB 3.0 external hard drive, I get a false "This device can perform faster..." message, as if I had plugged the drive in a USB 2.0 port.
The external drive I am using is a Western Digital MyBook Essential 1130. It is definitely a USB 3.0 drive, and came with the required USB 3.0 cable. While the USB 3.0 card was working, I got full-speed transfers to the limit of the hard drive's ability, about 90-100 MB/s. Now I can only get USB 2.0 speeds (33-34 MB/s). Windows insists I have the drive plugged into a USB 2.0 port even though it is plugged directly into the USB 3.0 card.
Things I tried so far: -rebooting and complete power cycle. No difference. -plugging the drive into one port or the other. Also no difference. -Looked in Device manager.The controller is recognized as a USB 3.0 device is using the proper NEC drivers.
Other info that may be important:
-No overclocking settings in use.
-I made sure the cable was plugged in all the way. It's in as far as it can go, but the ports will still only act like USB 2.0 ports.
I might as well throw the card away if it is only going to act as a USB 2.0 device.

I have been unable to connect to anything on my wired network, for about the last week. I don't remember making any changes however, I just became unable to connect.I having done a little troubleshooting.1. I can connect to the shares of my Windows Home Server if I use the IP address. The name does not resolve.2. Flushed DNS and restarting DNS server. Flushing DNS works on one client, to allow browsing by the name & restarting DNS works on the other. However neither works after a restart.3. Only my Wifi clients are experiencing this issue. My wired clients, desktops, PS3, Xbox 360, and Boxee can connect perfectly.This issue is not limited to my server. I can't connect to shares on my desktop, nor print to my wired printer.Some network background:I have DSL through CenturyLink and have a Linksys E2000 router.
