Just change the IRQ setting to a non conflicting IRQ address.

To do this,

Start Device Manager:

  1. Click Start, point to Settings, and then click Control Panel.
  2. Double-click System, and then click the Device Manager tab.
loadTOCNode(2, 'moreinformation');
  • If there is a problem with a device, it is listed in the hardware tree under Computer. Also, the problem device has a symbol that indicates the type of problem:
    • A black exclamation point (!) on a yellow field indicates the device is in a problem state. Note that a device that is in a problem state can be functioning.
    • A problem code explaining the problem is displayed for the device.
    • A red "X" indicates a disabled device. A disabled device is a device that is physically present in the computer and is consuming resources, but does not have a protected-mode driver loaded.
    • A blue "i" on a white field on a device resource in Computer properties indicates that the Use Automatic Settings feature is not selected for the device and that the resource was manually selected. Note that this does not indicate a problem or disabled state.


    NOTE: Some sound cards and video adapters do not report all of the resources they are using to Windows. This can cause Device Manager to show only one device in conflict, or no conflicts at all. This can be verified by disabling the sound card, or by using the standard VGA video driver to see if the conflict is resolved. Note that this is a known problem with S3 video adapters and 16-bit Sound Blaster sound cards, or those sound cards that are using Sound Blaster emulation for Sound Blaster compatibility.

  • When you select a specific device in Device Manager and then click the Properties button, you see a property sheet. The property sheet has a General tab.

    Some devices may have other tabs besides the General tab. Not all property sheets have the same tabs; some devices may have a Resource tab, Driver tab, and Settings tab, or some combination of these.

    At the top of the property sheet, there is a description of the device. When you click the Resource tab, the window in the middle of the tab indicates which resource types are available for the selected device.

    The list box at the bottom contains a Conflicting Device list. This list indicates a conflict with an error code.
  • Use Automatic Settings check box. If Windows successfully detects a device, this check box is selected, and the device should function correctly. However, if the resource settings are based on Basic Configuration <n> (where <n> is any number from 0 to 9), it may be necessary to change the configuration by selecting a different basic configuration from the list. If the particular configuration you want for the device is not listed as a basic configuration, it may be possible to click the Change Settings button to manually adjust the resource values. For example, to edit the Input/Output Range setting:

    1. Click the Use Automatic Settings check box to clear it.
    2. Click Change Setting.
    3. Click the appropriate I/O range for the device.
loadTOCNode(2, 'moreinformation');
  • If you click My Computer and then click Properties, you see a property sheet with a View Resources and a Reserve Resources tab.

    The Reserve Resources tab excludes a resource from use by Windows.

    The View Resources tab displays the resources that are allocated by Windows or inherited from a Plug and Play BIOS or PCI bus computer.
  • To disable a device in Device Manager, in Properties, on the General tab, clear to select the Disable in this hardware profile check box

Hi and welcome to FixYa,

Your posted problem may be addressed in a couple of methods:

  • ensure that your motherboard is ACPI compliant and if it is, ACPI enabled;
  • re-flash or update motherboard BIOS;
  • ensure that in the CMOS/BIOS settings & configurations, none of the IRQs are reserved;
  • clean the entire motherboard with particular attention to the PCI slots and devices installed in them;
  • a pencil eraser would be ideal to clean the little gold pins of the add-on cards/devices;
  • replace the Lithium CMOS battery.
Pls postback updates. Good luck and thank you for using FixYa.

HP TSGH-IR02 Remote Control how to install


This document pertains to HP Media Center computers with Windows XP, Media Center Edition.Use this document when the remote control does not work correctly with the Media Center software.Troubleshooting the remote controlUse the following items to troubleshoot when the remote control does not respond or when the remote control does not work properly. For example, when a key is pressed the selection moves all the way to the top or bottom of a list, or moves a selection many different places instead of the item you were trying to select.Before attempting these steps, make sure that PC has been updated with all of the latest Windows updates. Many updates for Media Center, like Update Rollup 1 for eHome Infrared Receiver, can be downloaded easily through the Windows Update software Tool.
Make sure that the batteries for the remote control are installed correctly and charged.Make sure that the front of the remote sensor is unobstructed, within a 45-degree range, and is less than 26 feet (8 meters) away. Disconnect all devices that use a USB connection except to the receiver, keyboard, and mouse. Restart the PC, and then try the remote again.If a pressed button repeats itself (sticks), unplug the IR receiver from its USB connection, wait one minute, and plug in the IR receiver. If the pressed buttons continue to repeat, alter the lighting conditions in the room or move the location of the IR receiver. Other remotes and HP Media Center PCs within range can also cause this issue.Try pressing the Enter key on the remote after changing a channel.If the remote control works when using the media center software, but does not work when changing the television channels, re-configure the Media Center software settings for the cable set-top box or satellite receiver
Point the remote control towards the IR receiver and press a button. A faint red light should appear on the IR receiver. If the light appears, then the problem is probably in the software that is using the remote control (most likely the configuration of the Media Center software). Close the software, restart the computer, and then re-open the software to solve this issue.

Troubleshooting the IR receiverThe IR receiver is the small device that receives the signals sent by the remote control. Use the following steps to test and reset the IR receiver.Disconnect the IR receiver from its USB port on the computer, maximize the Media Center window if it is open, and then reconnect the IR receiver. Test again.Point the remote control towards the IR receiver and press a button. A faint red light should appear on the IR receiver. If the light appears, then the problem is probably in the software that is using the IR receiver (most likely the Media Center software). Close the software, restart the computer, and then re-open the software to solve this issue.Click Start , right-click My Computer , and then select Properties .Click the Hardware tab and then click the Device Manager button.Click the plus sign next to Universal Serial Bus Controllers.If the eHome Infrared Receiver is listed under Universal Serial Bus controllers, Windows is properly detecting the IR receiver. If eHome Infrared Receiver is not in the list, or there is an exclamation mark or a question mark on the device, perform the following until eHome Infrared Receiver appears correct in Device manager:Unplug the end of the USB cable on the IR receiver from the computer and plug it into the same USB port.Plug the end of the USB cable on the IR receiver into the front USB port on the computer.Disconnect all other USB devices, leave the IR receiver plugged in, and then restart the computer. Plug in other USB devices after the IR receiver shows up in device manager.Figure 1: IR receiver listing in Device Manager









12_26_2011_1_30_40_am.gif
Testing the remote controlUse the following steps to check the responsiveness of the remote control:
  1. Open the Media Center software by double-clicking the Media Center icon the desktop or by pressing the green Start button on the remote control.
  2. Click Settings , and then click General .
  3. Click Check Your Remote , and then click Next .
  4. Press the numbers on your remote control. The corresponding numbers on the numbers on the screen should glow when each button is pressed. A faint red light should also glow inside the IR receiver each time a button on the remote pressed.
  5. Click My control is working properly , and then click Next . Do not click I am having problems with my remote control as this will not do anything.
  6. Click Finish after you are done.

My computer has a RAMDDR2 but would not start up,can u help me diagnose and troubleshoot?


First make sure you haven't installed too much memory. The computer uses DDR 2 memory but what is the maximum amount it can use. If it can only support 2mb and you have 4 installed the computer will read that as an error during boot up. Second, disconnect the Keyboard and as the computer is booting access the BIOS. disable the stop on all errors setting so it can get past not sensing the keyboard and see if that boots. If the computer boots after that the problem is a fault in your keyboard like a stuck key which will give you the constant beep. If you see the spalsh or BIOS screens then the problem is not the Video Card. If you don't get those screens double check and make sure the Video card is properly installed with nothing installed in a slot directly below it as this sometimes causes conflicts.

My hp laptop keeps on crashing when im using it, it brings a blue screen, wat cd be the problem


could be a number of things both software or hardware. Look for any diagnostic features that the vendor of the laptop provided. Try running those to see if it finds anything. The last problems i encountered had to do with bad memory. I had a laptop that constantly crashed. It even crashed by closing the CD drive quickly which would cause an abrupt blue screen at that very moment. It was pretty clear it was hardware, so i shut the machine off and removed the two memory modules, and then reinserted only one of them, and then started the machine back up. It worked fine. It would work fine with one or the other memory module installed, but as soon as both were in together, the system would become unstable again. I had another laptop with similar memory in it, so i borrowed its memory, and installed into the questionable system. The machine behaved perfectly from then and would not crash. I then found some memory cheap on craigslist and went and picked it up. Got home & installed it, and that machine has been running great now for months. Now, you're problem won't necessarily be the same, but when it comes to laptops, if it is hardware, its usually something you can influence by moving the machine around, and opening and closing doors/ bays/ CD drives whatever you have. If you find that you can influence the machine's behavior this way, its likely something loose, or something shorting. This is the problem with laptops. Lots of closely packed together things that can end up coming apart or together in the wrong ways. You may find it easier to just take the thing to a service outfit and let them deal with it, as this can get pretty ugly, and pretty time consuming to resolve. There's a mountain of software troubleshooting that can be done as well, but its so extensive. Too much to cover for me right now!
Good luck!

6. After all you fill-up click OK Button.
Note: Make sure that the IP Address you fill-up in your network connection are not the same with the other computer to avoid conflict. Just copy the configuration on the computer like: Subnet Mask, Default Gateway, Preferred DNS Server and Alternate DNS Server. Only the IP Address are unique to the other computer. Example; 192.168.0.5 that is the IP Address of last computer are connected in the network. The IP Address you able to use is 192.168.0.6, only the last digit of the IP Address your going to change.

Can i sync a handspring?


Recent version's of the HOTSYNC app have a provision for IR transfers (older versions may not though). So you should check the HOTSYNC app on the Visor and see if it already has IR transfer abilities. If it does: Use the downarrow to specify the IR transfer on the Visor. Setup HOTSYNC on the computer to accept IR transfers. Line up the ports and tap the HOTSYNC button on the Visor's display. If it doesn't: You may be outta luck. Downloading an updated version of the HOTSYNC app (or some other utility) won't help because you'll need to Sync in order to get the app on the Visor.
