What is Microsoft Windows XP Mode?
Windows XP Mode is an optional feature of Windows 7 Professional, Enterprise and Ultimate editions and provides additional application compatibility. It allows you to install and run many of your productivity applications for Windows XP directly from your Windows 7-based PC. It utilizes virtualization technology, such as Windows Virtual PC, to provide a virtual Windows XP environment for Windows 7.

What is Microsoft Windows Virtual PC?
Windows Virtual PC is the latest Microsoft virtualization technology designed for Windows 7. It is the runtime engine for Windows XP Mode to provide a virtual Windows environment for Windows 7. With Windows Virtual PC, Windows XP Mode applications can be seen and accessed from a Windows 7-based PC.

What are the Requirements for Windows 7 Virtual PC and XP Mode?
  • The CPU needs to support Hardware Virtualization Technology and is enabled. Intel names its Virtulization Technology - "Intel VT". AMD names "AMD-V"
  • 2GB memory or higher recommended
  • 15GB hard disk space per virtual Windows environment
  • Supported host Operating System:
    • Windows 7 Home Basic
    • Windows 7 Home Premium
    • Windows 7 Professional
    • Windows 7 Ultimate
    • Windows 7 Enterprise
    • Note: Windows XP Mode is only available in Windows 7 Professional, Ultimate and Enterprise Editions
  • Supported guest operating systems:
    • Windows XP Professional Service Pack 3
    • Windows Vista Ultimate and Enterprise edition
    • Winodws 7 Ultimate and Enterprise

I installed a new video card. I turn on the power, and there is no video!
This problem could be due to the improper installation of the video card. The video card needs to sit into the PCI-express or AGP slot "naturally" so that every gold finger on the card can connect to right pin inside of the AGP or PCI-Express slot. The distance between two of the gold fingers on the AGP or PCI-Express card is extremely small. If the motherboard was not installed properly inside of the computer case, and the video card was forced into the AGP or PCI-Express slot, the gold fingers may not be correctly contacting the AGP or PCI-Express connectors. To fix this, you may need to adjust the motherboard's position inside of the case by slightly loosening the screws. You could also try removing the motherboard from the case entirely. You can test the system outside of the case on the motherboard's box. This will eliminate the guess work, while ensuring that the motherboard is not grounding out on anything inside of the case. Next, try reinstalling the card by using less force while ensuring that that card is properly aligned with the video card slot. Do not try and install the card by inserting the card at an angle (one corner first, followed by the next). The card should be perpendicular to the motherboard, so that both sides of the card will be inserted into the AGP or PCI-Express slot at the same time. Be gentle.

I installed a new video card. My PC keeps on freezing, locks up, and/or re-boot!
  • Verify if you installed the latest drivers for your motherboard which enable AGP functionality for the motherboard chipset. These drivers may be referred to using any of the following names
    • AGP Driver
    • AGP Miniport
    • AGP VXD Driver
    • Chipset Driver
    • GART Driver
    • VGART
  • Verify if you installed the latest drivers for the video card and/or the sound card. If you need to reinstall a new driver, please follow the instructions closely. We suggest you remove the old driver before installing the new one.
    You should also check your game's website for the latest patch files for the new video card.
  • Verify the new video card is not sharing an IRQ with another device. If it is, you may need to change the IRQ setting.
  • Your computer may be overheating. You may need to open the case and aim a regular fan inside. If this corrects the problem, purchase a second case fan.
  • Verify that your system has a minimum power supply of 300 Watts. We suggest you install 350 Watts.

After installing a Kingston HyperX DDR400 CL2(2-2-2) DIMM module, (for example: KHX3200/256 ,KHX3200/512, KHX3200K2/1G, KHX3200K2/512) into a system with an Intel i865PE, i865G and i875 chipset, the system will not boot or function correctly.
The default SPD timings on the HyperX KHX3200/xxx modules are too aggressive for the motherboard. There are two possible resolutions:
  • For Expert System Users:
    Enter the BIOS setup screen for your PC or motherboard and check whether you can change the memory timings. If you can change the memory timings, you need to change the following parameter:
    1. RAS-to-CAS (also called RAS-to-CAS Delay or tRCD) to 3
    2. You will also need to increase the voltage to the memory to 2.75V.
    If your BIOS setup does not allow you to change memory timings, then please use the solution below.

  • For Non-Expert Users:
    Please use Kingston's HyperX DDR400 CL2(2-3-2) DIMM modules, for example, KHX3200A/256, KHX3200A/512, KHX3200AK2/1G, and KHX3200AK2/512 memory modules instead. Their timings are verified by Kingston engineers to be compatible with i865 or i875 motherboards.

I installed a new AMD CPU and CPU cooler onto my motherboard. The motherboard runs for a few seconds, then shuts itself down!
The problem is your CPU overheating. You need to apply thermal compound, or a thermal pad, to the top of the CPU before the cooler is installed. This will help transfer heat from the processor to the cooler. If you do not use thermal compound, any slight misalignment of the cooler, or even the presence of dust, will prevent heat from being efficiently transferred away from the processor. If thermal compound is not used, you also risk frying your CPU. When applying thermal compound try not to overdue it. Too much thermal compound could cause your CPU to appear to be defective.

My motherboard does not recognize the IDE devices.
This typically caused by physical configuration problem.

1. Incorrect cable connections
  • Using Ultra ATA 80-conductor cable
    Please make sure that the Master or Single drive is on the black end connector. Connect any Slave device present to the grey middle connector. Finally, the blue end connector should be connected to the motherboard or EIDE controller card.
  • Using a standard 40-conductor IDE cable
    Please connect the Master device to one end, the Slave to the middle and the other end to the motherboard.
In all cases, make sure that the red stripe on the IDE cable is aligned with pin-1 on the motherboard and pin- 1 on the drive.

2. Incorrect jumper setting
The most common incorrect jumper setting used is for a drive that is alone on the data cable. Keep in mind that the concept of Master/Slave applies to a given EIDE channel. If there are two drives on the data cable, one must be Master and one designated as Slave. If the drive is the only device on the cable, it should be jumpered as a Single drive, NOT a Master.

An EIDE device is detected by the BIOS but not by Windows 2000/XP. The drive is not listed in Device Manager or Windows Explorer.
A setting for the IDE channel in Device Manager may be responsible. Make sure that the IDE channel Device Type is not set to None in Device Manager for the drive location of the missing drive.

To resolve this, open "Device Manager".
1. Under IDE ATA/ATAPI controllers, double-click either Primary IDE Channel or Secondary IDE Channel, depending on where the missing drive is connected.
2. Click the Advanced Settings tab.
3. Locate either Device 0 or Device 1 (0 is the master device and 1 is the slave).
4. Check the drop down box labeled Device Type: and make sure it is set to Auto Detection instead of None.
5. Click OK, close Device Manager, and restart the system.

My mouse moves slowly. I hear crackling sounds from the sound card after I installed a new video card.
Verify the new video card is not sharing an IRQ with another device. If it is, try moving your sound card, or other PCI card, to another PCI slot.
