Although desktop keyboards can be quickly and cheaply replaced, this is not the case for laptop computers where the keyboard is integrated into the computer itself. Established keyboard testing utility KeyboardTest has been used to test and check for faulty keyboards by PC enthusiasts and production line environments in batch mode testing since Features Both the down stroke and the up stroke are highlighted in different colors.
To solve this, you can edit the registry to enable it by adding a EnableLinkedConnections value :. Can I test two network cards on the same system connected to each other? Two network cards on the same system connected directly with a network cable can be tested by the standard network test however care must be taken when setting the test up to have it work as expected.
First connect the two network cards directly with a network cable and assign each network card a static IP, e. Next open the network test settings, BurnInTest users the entered IP addresses and assigns them to a network card based on the order as seen by the operating system, they cannot be assumed to be in name or IP order.
To check what order BurnInTest see the cards in select the Advanced network test option and then click the Advanced test options button. This will display the list of available network cards, see the picture below for an example and note that network card with the Select the "All available physical ethernet ports" option and for the first address to be tested enter the IP address that was not the first entry shown by the advanced network test, in this case Now when the test runs it will find the first network card, Common causes for a system crash are device driver and hardware problems.
When a system crashes it will display a diagnostic screen Blue Screen Of Death or restart, depending on your systems configuration. If a BSOD is displayed it may display helpful information, such as the name of the device driver that crashed. Otherwise, you can use this diagnostic information to search the Internet for possible solutions to your problem. Excessive heat can cause a system to fail over time, so monitoring the temperature while stress testing the system can help identify this.
Problems can occur if your computer runs out of system resources because there is some process or driver that does not release memory, handles, semaphores, etc. After a long period of uptime Windows runs out of resources and dies a terrible death. What can you do about this? Identify the offending software, if you can, and disable it.
This can even be a bug in the Operating system however. Computer can have a Random Crash. What do we mean by this? Many things can bring down a computer. Typical things would be a spike on the power line, a strong burst of Electromagnetic interference e. If your system is running at its limits due to overclocking or your components are running at the top of their temperature range, small external influences can push your system over the edge, resulting in a terrible death.
If you believe in Chaos theory and most scientists now do , then you also must believe that computers will just crash unexpected from time to time, how often would depend on the design tolerances built into your hardware.
Timing issue. Classic examples of this are Hardware or Software Interrupts occurring in a critical section of code. What can you do about these types of bugs? Almost nothing as a user. They have plagued software since the first line of code was written they are very difficult problems to find and are almost never picked up during software testing.
Problems can occur in Drivers, the operating system, your hardware, everywhere. As everyone is always on a tight deadline, endurance testing often does not make it into a software developer's test plan. What follows is some hints on how to go about finding the cause of a particular system instability.
We do not want to try and explain the steps involved in each of these processes, they are just some points that may warrant future investigation. After receiving quite a few reports of this issue on the Intel Haswell iGPU we have investigated further. In addition to the reasons shown above, we have found in our testing that this issue is caused by the Intel graphics card device driver timing out and recovering.
This occurs with the driver We could not reproduce the problem with driver For reference, the following is a description of the problem when using driver The System and Application event logs should be checked around the time of the event. To view the events, open Event Viewer, expand "Windows Logs" and select "Application", look for "Desktop Window Manager" and "Windows Error Reporting" events around the time the 3D test was interrupted event occurred see example from our test lab below.
Then select "System" events and look for "Display" Warning events e. Problems with 2D and 3D testing on Windows server and Windows server? In Windows and server, and. NET server all video card acceleration is turned off by default. It seems that Microsoft's position is that this acceleration is not required for typical server functionality, to fix this:.
From the General tab, click Advanced, then select the Troubleshoot tab. Move the "Hardware acceleration" pointer to Full. BurnInTest crashes at the start of testing. This might result in a hardware reset, an invalid page fault or a partial crash with a window being empty black. If BurnInTest creates a detailed minidump debug file, please email it to us, e. The most common reason for a fault like this is a problem with the 3D test which uses DirectX 9.
There are several video card drivers that do not support hardware accelerated DirectX correctly or have bugs under particular versions of Windows.
This can result in a system crash and sometime strange rubbish appearing on the screen. What you should do is:. Several hardware manufacturers produce video cards which have very poor software support for 3D graphics DirectX. This is especially the case for the cheaper, bottom of the range video cards.
Poor drivers can result in strange visual artifacts appearing on the screen, poor 3D performance and system crashes. The old saying of, "you get what you pay for", seems especially true for video cards, Beware. Temperature monitoring of my USB drive only works sometimes.
When this occurs, the BurnInTest temperature graph will show no results for the USB drive temperature from the point in time that this problem occurs.
I have an ATI Radeon video card and after running for a while the system hangs. Try newer driver versions and if this does not work, try older ones. BurnInTest crashes with rubbish on the screen or a black screen when the monitor power save feature turns on after X minutes of running.
Some video cards' device drivers seem to have a bug that causes this crash when the monitor goes into power save mode. If you disable the monitor power save feature from the Power Management window in the Windows Control panel this resolves the problem. The main offender seems to be the Maxtrox G video card. We have had only 1 report of this problem, so it does not seem to be very common.
If you are testing serial ports at a high speed, together with USB ports, it should be noted that some chip sets have been reported to have limitations while under load high load. Contact your manufacturer regarding these types of limitations. I get an error with the parallel port test, "Error loading parallel port device driver".
This problem can occur when you are running BurnInTest Professional from a networked drive. In the search results, find and click System Restore. Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image. If this Step 2 fails as well, please proceed to the Step 3 below. In the Windows Update dialog box, click " Check for Updates " or similar button depending on your Windows version If updates are available for download, click " Install Updates ". After the update is completed, restart your PC. Click the appropriate "Download Now" button and download your Windows file version.

This does not apply to customers from outside of Australia. For hardware items, the customer will be considered the importer and PassMark will not be liable for VAT.
California sales tax will be collected for orders billed or shipped to California. This only applies to hardware items and is calculated at checkout. No other tax or duty is collected by PassMark, but depending on your country and state, local taxes, duties or fees may apply. You are responsible for all non-Australian taxes and duties imposed by your government and any costs associated with paying these taxes.
If you select the FedEx shipping option, PassMark will however pay the "Fuel surcharge" that FedEx is currently adding to their shipping rates. Please also see the following notes about customs restrictions which may prevent a package from entering a country. What if the package is rejected by customs in my country? Some countries have strict import restrictions or may require a customs broker in certain situations.
Any packages rejected by customs and returned to the shipper, and any additional shipping costs necessary such as the need to resend the package will be at the cost of the customer. Note that PassMark cannot have a comprehensive and up-to-date knowledge of all import laws around the world.
So please check the custom laws of your country and arrange for any special handling requirements before your purchase if this is necessary. What is an advancement fee? Many countries have no duty or taxes related to imports, especially for low value items. Hence, this does not apply to most orders. But when couriers, such as FedEx, ship packages across international borders, they sometimes pay in advance the local government fees, duties, and taxes that you owe.
When they deliver the package to you, they collect the money that they have already paid to the government on your behalf. In addition, they sometimes collect an advancement fee for the service they provide by paying your charges in advance. These advancement fees go to the courier, not to the government or PassMark. You are responsible pay them, along with any taxes, duties, and fees charged by your government, at the time your package is delivered.
