If you do not see the COM or LPT port number in Device Manager see this FAQ for PCI/PCIe expansion cards: -us/faq/pci-pcie-cannot-boot-os-or-detect-windows\\n\\tor this FAQ for USB devices: -us/faq/usb-cannot-detect-windows
To find the correct driver for the hardware installed in you computer sometimes it will be neccessary to discover what the hardware manufacturer name is. The illustration below shows an example of how we can use device manager to discover that the audio card manufacturer is Conexant.
Once this is complete, reboot your system and enter into your system BIOS (check with your manual on how to do so). This varies by system however commonly you will find a listing for integrated devices. Enter into this option and locate either onboard video or display boot priority and select auto or PCI-e / PCI / AGP depending on the type of card you have purchased. once complete save your settings (typically F10 then Y for yes) then shut your PC down completely.
@Judy M: 1. Create first the LENOVO recovery disks (for backup reasons) and then 2. Boot from the Win7 install disk and start the Windows installation. 3.Delete all the partitions on the disk. 4. Select the \"Unpartitioned\" space to install Windows. 3. When asked DO NOT enter a serial number and finish the installation.From Windows: After installing all the drivers needed for your system, try to \"Activate Windows\" automatically (enter the Serial number and activate) and if you have problems with automatic activation: Click Start and in the Search box, type: \"slui.exe 4\" (without quotes). Select your country and click the \"Phone Activation\" option and activate Windows by phone.
@Abhishek: Press F8 to enter to Advanced options menu and select to boot to \"Last Known Good Configuration\" or Select \"Disable driver signature\" and then from Windows disable the driver signature completely (Solution 2 on this post).
If you see a driver called risdxc64.sys in callstack of SYSTEM that causes the high CPU usage, update the Ricoh PCIe SDXC/MMC Host Controller driver or disable the SD card reader in device manager if no driver update fixes it.
Another way that you control audio recording and playback is by choosing your audio input and output drivers. If you only have one sound card you don't normally need to worry about this. There are two places you can configure your audio drivers - in the RealBand program, and in the Windows control panel (assuming you are using MME; ASIO is only configured within the recording program and ASIO driver control panel):
Windows XP and earlier operating systems: Whenever you launch the Windows sound card mixer, it always opens showing the mixer panel for the currently selected audio driver in the Windows Control Panel.
If you get an error message when you try to open the sound card mixer or nothing happens when you try to open it, this means that the selected audio driver doesn't have an associated Record or Play Control window. In this case, the audio device will usually have a separate control/mixer console that you can access from the Control Panel. You will need to check with your sound card documentation if you are not sure where to find it.
For recording or playing live from an external MIDI synth, one solution is to use a MIDI Output Driver with no noticeable latency. This could be the built-in MIDI synth on your computer's internal sound card, or your external MIDI keyboard or sound module. If you prefer the sound quality of the soft synth, you can record using a no-latency driver, and switch back to the soft synth for playback when you have finished recording. You may not have a hardware synth MIDI device to use, in fact most new computers that you purchase come with only the GS Wavetable and no dedicated \"sound card\".
The Microsoft GS Wavetable is a software synthesizer included with Windows. The sounds are somewhat similar to the Roland VSC, but they are lower quality sounds, and there are fewer of them. The latency of the GS Wavetable varies between different computers with Windows XP - it is usually about 120 ms. On Windows Vista and 7, the latency is higher, about 210 ms. As far as we are aware, there is no way to reduce the latency on any particular computer. Unfortunately, many new computers don't include a sound card with a built-in MIDI synthesizer, so choosing a \"no-latency\" MIDI output driver for recording may not be an option. In many cases the GS Wavetable is the only MIDI output driver choice, aside from purchasing a dedicated sound card, using an external synth/sound module for output, or using a DXi/VSTi synth (see below).
RealBand supports either ASIO or MME audio drivers. One of the main advantages to using ASIO in RealBand is that it allows you to play live from an external MIDI keyboard through a DXi synth with little latency. When using MME drivers with a DXi synth (such as the Roland VSC-DXi or ForteDXi), live playing is routed through the MIDI output driver rather than DXi synth. This is desirable because the latency of your MIDI output driver could be less than that of the DXi synth. However as discussed above, it may not be great if the only 'MIDI output driver' you have is the GS Wavetable. Manufacturers of dedicated sound cards usually have ASIO drivers available. If the manufacturer of your sound card doesn't have an ASIO driver, OR if you are having trouble using a specific ASIO driver, the free ASIO4ALL driver is a great substitute and works very well with most systems.
If you have a sound card or audio interface that has more than one input port, you can record from each port on a separate track. You can record as many tracks simultaneously as your hardware supports. To set this up in RealBand, go to Options Preferences Audio Drivers. If you are using the ASIO diver type, select each input port that you want to use by control-clicking. If you are using the MME driver type, select each input driver that you want to use, and make sure that Microsoft Sound Mapper is not selected. To record, you simply need to select a single track - RealBand will use as many tracks as it needs to. Note that each Input port is a stereo pair, with a left and right channel. If you select 4 Input Ports, then you would be actually getting 8 input channels, since each audio port has both a left and right channel. This would use up 8 mono-audio tracks.
You might be using a software synthesizer MIDI output driver such as the Roland VSC or Microsoft GS Wavetable (check this in Options Preferences MIDI MIDI Devices). Software Synthesizers usually have noticeable latency because the sound is processed by your computer's CPU before being sent to your sound card. This means that there is a delay between when RealBand sends the MIDI data and when you hear it played. You should consider using a DXi synth, such as the VSC-DXi, by checking the box 're-route MIDI playback to default DXi synth' - this would likely solve the problem.
In RealBand, if you have \"Microsoft Sound Mapper\" selected as your audio driver, RealBand will use whatever is configured in the Windows Control Panel. If you have a driver *other* than the Microsoft Sound Mapper selected, RealBand will use that specific driver. Make sure you don't have the Sound Mapper selected in addition to another driver. To correct this problem, you will most likely need to use a single sound card for audio playback.
In the audio drivers menu, (Options Preferences Audio Drivers) check to see that Microsoft Sound Mapper is not highlighted in addition to your sound card drivers. Only your Sound card drivers should be highlighted, unless you only want to use the default audio driver selected in the Windows Control Panel.
You must be using an ASIO driver for \"DXi/VSTi play-thru\" to work, because this feature requires a low latency driver. In RealBand, you can set this up by going to Options Preferences Audio, and selecting ASIO as the Audio Driver Type. This requires that you have ASIO drivers for your sound card installed on your computer. If you aren't sure, you should check with the sound card's documentation or manufacturer.
If you get the error even if the MIDI Mapper is not selected, there is most likely a problem with the way your sound card is installed. We recommend reinstalling your sound card using the latest drivers available from the manufacturer. Check the manufacturer's website for driver updates.
The two most frequent causes of this problem are (1) you have outdated, buggy, or incorrect sound card drivers installed on your computer, and/or (2) the latency is set too low in the sound card's ASIO control panel.
The first thing you should do is go to your sound card manufacturer's website and download the latest drivers available for your sound card. For some sound cards, you may have the option of downloading more than one different type of driver. If you are not sure which is the best to download, you may want to contact the sound card manufacturer.
Next, go into Options Preferences Audio and click on the [ASIO Driver's Control Panel] button. This should launch your sound card's control panel where you should see a latency setting. The setting may be referred to as \"buffer size\". Note: some cards require that ASIO not be in use when you change the latency setting. In these cases, you will need to either close RealBand, or select the MME driver type temporarily, then open the sound card's control panel from outside of RealBand. You may have an icon in your task bar to launch the control panel, or you may be able to access it from the Windows Control Panel. In any case, increase the latency setting until you don't experience any playback or recording problems.
How low you will be able to set the latency depends on how powerful your computer is, the quality of the sound card drivers, and what steps you have taken to optimize digital audio performance on your computer. There is a list of a number of things you can do to improve audio performance on your computer in FAQ topic 87. 153554b96e
