USB And PS/2 Devices Seen By BIOS But Not By Windows
Jan 1, 2011
I am able to get into the BIOS with both USB and PS/2 devices (Keyboards, etc.) but one I boot into Windows I am completely unable to log on. Keyboard does not work, and neither does the mouse. They both light up, but I am unable to get other things to activate (caps lock key, etc.) and key presses do not work. This is with either USB keyboards and mice, PS/2 keyboards and mice, or a mix of the two (or all four attached at once!). Going into safe mode does not work -- once again, anything USB-based or PS/2-based ceases to function once windows boots, and therefore I am unable to log on in order to diagnose the issue.
I have re-set my BIOS to the default settings, and have removed anything which may provide my system with additional IRQ's -- including both serial ports and my LPT port (yes, this is an older machine). I have gone into the recovery console, and things *DO* work there, strangely enough. I do have mouse and keyboard support, but bringing the machine back to a previous state (system restore) does nothing to correct the issue. As well, the first few attempts provided me with an 0x800700B7 error message (very strange!) when the restore attempt failed. I got past this issue by choosing a restore point a few days in the past.
Once in the recovery console, I notice that it seems to be strangely deficient in tools that I would actually like to use. I am unable to bring up the MMC (and thereby the hardware devices applet), nor am I able to employ gpedit.msc in order to disable the login (boot straight into Windows). Essentially, it seems that my only tools are the command line, and about the only thing that I have found that can be launched from the command line - regedit. I am running a personal copy of Windows 7 Professional, with all of the latest updates and patches. I have MSE (the newer version) installed and have also installed malwarebytes anti-malware. Nothing found to date.

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 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.

I've got an Acer Model As5742 Laptop with an i5 480M processor and 8 GB of good Ram. I'm running Win 7 Pro 64 Bit. It's only about 5 months old and this started about a month ago. I have no other problems. IE: Blue Screens or Lockups or anything, just the Bios clock changes to a random date and time after every restart. I replaced the Bios battery twice and it only effects the chore of having to reset the time in Windows every time I boot.
I'm going to send it to Acer to be repaired within a week or two, but maybe it's not a bad timing mechanism in the motherboard and one of you people have a correct solution to it. Which will save me the trouble of sending it in for a motherboard replacement.
I do have all the drivers and bios updates installed. Oh yes I've ran about 15 different virus Etc. Malware scans with several different products and they all come back clean. I ran System File Checker SFC /scannow from the command prompt several times that also comes back OK.

I have a five-month old HP Compaq Presario Laptop, which has been working fairly decently (I've had a few virus scares, and my Norton quarrentined something a twenty days ago). On HP's advice, I just updated the BIOS on my laptop. It's currently stuck at Verifying New Bios Image, and it's at 100% - It's been stuck that way for a half-hour plus.

My Samsung series 3 laptop has been sending out popup messages telling me I need a bios update, I go to the Samsung software update site and this bios update has been failing, I have made several calls and chats to techs at Samsung who tell me to do what I have already done, they tell to ask for tier 2 tech, who can go in my computer and fix it , When I finally got a tier 2 tech, they told me the same thing, I told him what I had been told about him and what he could do, He said, is it working , I said yes, but settings on computer change on their own,like wifi turns itself on and that concerns me. Anyway, He said that it didn't need a bios update,even the Samsung website said this computer needed a bios update. I posted this on hardware,firmware concerns, and they told me to post here, I was going to go to a site ,that had a download that checked drivers,

i have an old windows xp pc that my son uses for chat and homework for printing. the problem i,ve now got is he and a friend of his has formatted the pc and installed windows 7.i do know that some of the devices do not have windows 7 drivers because i once checked when he asked me could he have win 7 on it. i didnt bother to upgrade the pc as there was no need.the problem he now has is that everything works but there is nothing on the monitor. it says no input. i have researched on google and the answer i get is because there is no win 7 driver for the nVidia GeForce FX5200.

I've lost all my usb drivers and windows will not connect or recognize any usb device when I install it. Here's the message I get from device manager:Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39). I've tried everything possible to correct the situation even reloading the intel chipset from Asus web site. Windows no longer will detect a flash drive or external usb drive. I'm at the end of my rope and I don't envy the thoughts of a reinstall. Is there a way to reinstall the usb drivers?Any one can point me in a direction.

I just recently installed windows 7 home premiuim on my windows vista home premieum computer. When my computer booted up with windows 7, everything worked perfectly and had no problems. 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've been having a major problem with for over several months. I've recently started to make music and I'm interested in using some of the MIDI capabilities on several of the instruments I have, mainly drum machines and synthesizers. The problem is Windows 7 is not detecting these MIDI to USB interface devices and instruments I have.I've tried using three interface devices so far with no luck what-so-ever. I've tried different two types of MIDI to USB cables, these are generally small, and they both work because I tested them on my friends Macbook and they were 100% functional.So, I decided maybe I should get a better piece of recording equipment, thinking there would be better platform support, so I purchased a Focusrite Saffire 6 USB, low and behold, I had the same problem!The MIDI to USB cables and the Focusrite interface detect the MIDI IN coming from the MIDI OUT port of the instrument, however Windows is not reading the converted MIDI information running through the USB cable into the computer.Here's a list of the solutions I've tried.Updating my chipset drivers. Uninstalling and re-installing chipset drivers. Un-installing and re-installing my sound drivers. Using the latest USB drivers (and even beta drivers) and utilities provided by the interface products. Trying different USB ports assuming it was a power issue. Uninstalling and re-installing the product drivers, rolling back to older drivers as well. Updating Windows. Tested under two different DAWS; CuBase and Sony ACID. I also tried different stand-alone soft-synths, they didn't detect the MIDI devices either. I've tried a few obscure MIDI drivers I dug up from a few places, but to no avail, I un-installed them. I've tried sacrificing 3 goats to Microsoft, that didn't work either. I'm convinced that this is a Windows / Hardware compatibility issue. I'm tempted to get a Mac product so I don't have to worry about this time pilfering fiasco. If anyone would like to take a stab at this I would be very grateful.Here's my system specs:

I have a computer on which the usb devices stop working/receiving power once windows has loaded (they work up untill windows finishes loading). I installed windows on a different disk everything else remained the same, now the mouse and kb work. Is there a known fix for this? If not is it possible somehow to transfer the user settings from one disk to another, so i get the same settings on the new drive perhaps (mind you, no mouse or kb support on one of those windows)?I have tried a lot of windows disk fix things, none of them have any effect, very strange, have never seen this before. Usually i get pretty much everything fixed using google, but this one.

I was using my laptop fine for a few month now. I let a friend use it for a week and he "somehow" got a virus . I wasn't too stressed as i didn't have any personal information or anything important on it. So i reinstalled Windows using my flash drive, the iso from the Windows 7 Professional 64bit CD i had, and the Windows USB-DVD tool downloaded from Microsoft. I changed the boot priorities in BIOS to my USB drive, went through the installation setup and formatted all the partitions on my HDD and installed windows 7 professional 64bit. It loads up and for the most part works fine.First off my resolution will not go above 1024 x 768. Even though previously it was a lot higher, can't remember exact resolution, but was higher than that. Next, when i go to device manager, the following are listed under Other Devices with Yellow Exclamation points by them; Ethernet Controler, Network Controller, PCI Simple Communications Controller, and SM Bus Controller. I've Googled, searched these forums, and tried each solution out there. But to no avail.I purchased the laptop from Best Buy but i do not have any kind of recovery CD's.
Basically i think windows is not properly recognizing the hardware i have installed. Because the laptop screen can go to a higher resolution, but windows won't recognize it properly. Even Windows Aero isn't working properly, and the computer is marketed as a gaming laptop, so i know it has the graphical power.Feel free to explain in detail as i'm pretty good with computers but this problem has me stumped. And for a person that will not stop until something is fixed, its driving me crazy.I'm doing this off another laptop i have that has access to the internet (obviously). So if there are any programs i need to download i have the ability to do so.

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...

I have an Iogear bluetooth dongle that until a couple of weeks ago was working fine. I use it to connect to a bluetooth keyboard. I went on a trip and took the keyboard with me, where I paired it with my iPad. When I came back, the bluetooth could no longer find the keyboard, or any other bluetooth device for that matter.I've gone through all of the usual troubleshooting steps, including making sure it is set to run automatically, making sure the device drivers are updated, removing and reinstalling the device drivers, making sure the bluetooth settings are correct as far as set to find devices etc. with no luck.It does appear to be working as far as the device goes. There is a blue light on the dongle that blinks when I click to find a bluetooth device. When I put the bluetooth on the computer into discover mode, my phone is able to find the bluetooth radio, but it cannot connect with it. All of this, and the fact that it worked fine before, leads me to believe it may be a problem with my computer. I ran antivirus software, and although it found a couple of malware programs, nothing changed.

Here's what you need to do for both 32 bit and 64 bit Windows 7 systems:
- Download the 'Windows Mobile Device Center' ( current version is 6.1 ) which you can download it from url...this works for both Vista and Windows 7. I've tried it on both.
- Install the downloaded software but it may not look like it worked on Windows 7 PCs. Vista automatically configures the settings on the bluetooth devices but for those who have Windows 7, here are the things you should do:
- Go to 'Device Manager' from 'Control Panel' -Or- just right-click on Computer Icon and choose 'Properties' and then click on 'Device Manager'.
- You'll see an 'Unknown Device' named 'Bluetooth Peripheral Device'
- Right-Click it and click on "Update Driver Software" -Or- anyway you find it easy to bring up the Update driver window.
- Click "Browse My Computer for Driver Software" button.
- Click "Let Me Pick from a List of Device Drivers on my computer".
- Select 'Bluetooth Radio' from the list if it asked you to select and then in the next window, it will show a list of drivers with Company Names in one list and Drivers in another. In the Company List choose 'Microsoft Corporation', not only Microsoft.
- From the drivers list there may be one or more drivers with the name "Windows Mobile-Based Device Support" with different driver versions. Select one or the latest.
- Ignore any warnings and keep pressing next and then Finish at last. If all goes well, the last screen will show the message that device driver is successfully installed.
Now, after manually updating the driver for your bluetooth device, in 'Device Manager' when you click on 'Bluetooth Radios', it should display one more item which will say 'Windows Mobile-based device support'.There are few more things that you want to pay attention to. If you have already added the device in your 'bluetooth device list' that didn't work, then remove the device and add it again. After you add it, you might need to restart the computer if it gave you a connection problem error message. Every PCs that had Windows 7 and Vista worked after installing this software and I hope it will work for you too.

I recently upgraded my Acer Aspire One AOD150 Netbook to Windows 7 (32Bit) Home Premium with a clean install, everything works fine except for Bluetooth. I have installed latest drivers from the Acer site but to no avail. According to the Acer Hardware detection utility I have a Broadcomm Bluetooth card.
The Netbook OS was originally Win XP with a Logitech V470 Bluetooth mouse which worked perfectly, I could also discover and user phones and other bluetooth devices.
I have checked to make sure the Bluetooth services are started, and also checked to make sure that Power Saving on the mouse is not enabled (this caused loss of device problems with my new Windows 7 (64bit0 PC - so I disabled it on the Netbook as well)
It seems that no Bluetooth devices can be discovered, I have checked that the Bluetooth is switched on and tried discovering other mice, phones and computers but the system resolutely fails to see any Bluetooth devices at all!

I completely formatted my computer to Windows 7 Ultimate 64 bit from Windows 7 Home Edition x64, I put in the correct product key and then when I attempted to connect to the internet I couldn't because I don't have the correct drivers.Back when I used to use Windows XP I put a little CD in and then installed the drivers from Device Manager but now with Windows 7, I put the CD in and I can't install the drivers. They show up with a tiny symbol with a yellow exclamation mark on it (it was like this too back when I used XP, but I had no problems then,).
The uninstalled drivers are these:

I have a sort of file/media server setup on one of my boxes as I need a few programs running on it that can't be run on anything else (Well XP, but I'd rather have 7 running on the system).Well the problem is that none of my other computers can access it other then my main rig and another laptop which are both running Windows 7.My Macbook and Android can't connect to the Server.When I restart the Server, the Macbook and Android can connect to it for 30 minutes or so. As long as it's always running, it'll stay connected such as when I'm streaming a movie, but if it's inactive it'll cut the connection and will be unable to reconnect.If my Macbook can't connect, my Android device can't and vice versa. I don't want to have to restart the Server every time I have to reconnect so any help? I've tried changing the Local Security Policies, changed the network settings to not use 128bit encryption, but nothing is working.On the Server it just has Windows Firewall and Microsoft Security Essentials.
