Hi Tigistunet
are there any bleeps on startup? try checking that the card in in securely, remove and replace should be sufficient, if no joy then I think that your graphics card is most likely at fault, this will stop the pc from booting and prevent the mouse and keyboard from being powered up. Unfortunately it could be almost anything but I would start with the graphics card. Hope this helps.

Hi Tony.

Here's a great YouTube video showing you how to do this (assuming you're using Windows 7). You'll need a Windows 7 CD to do the install, or other media.

First go into device manager and check to make sure the audio driver is present. If it is, try uninstalling the driver and re-installing it. Also, I have to ask the obvious.....are the speakers plugged into the right outlet, plugged in and are they not muted? Also go into control panel and select the proper output in your audio settings.

Since Windows 7 all drivers can be downloaded from Microsoft. You only can install Microsoft certified drivers on a windows 7 or 8 machine.
When connecting an Android system to your computer it should see the computer needs a driver and a program and should hint you it want to download something.
When you have an older operating system, I think you need to contact the maker of the Android device and ask them not only for a driver, but also for software that will work on that version of Windows.

Three great free programs will solve your problems on cookies. The first is CCLEANER, second one is SuperAntiVirus from superantivirus.com and another good one is Malwarebytes.

These are great programs and free to use. The CCLEANER program will also help clean the trash from your registry too, There is a tab on the left side to clean and fix the registry. I have been a very happy user of all three of these great programs and then purchased the full version which is even better. Try them out! Regards, Dennis

Native Resolution 1280 x 1024 for the monitor. If your Video card has any other resolution there is a mismatch.
Update the drivers for your Video card and see if you can get the native resolution from the PC, on the Monitor, reset all the settings to Factory defaults.

The drivers, made for older windows versions, won't work on a Windows 7 or up machine. Not even in compatibility mode. Microsoft needed to make Windows more secure, so only allows drivers in there modern operating systems when they have a Microsoft certificate. For a certificate the manufactures must use Microsoft protocols, ask Microsoft for certification, and pay for the tests Microsoft does, to check the software is working correct. So no manufacturer will ask for certification of drivers for hardware they no longer sell.

Long story, but unless you can write your driver yourself, or you can find an universal camera driver (not sure something like that exists) you won't be able to use the camera. Nobody does tell you, after you update your OS you also have to buy new hardware to.

It may be because you have a newer version of Internet Explorer already installed. Internet Explorer comes pre-installed on every Windows PC, and is usually updated regularly as part of the Windows update. I believe the current version is IE 11.

Chances are the music files are not in a format that your car stereo recognizes. Check the booklet that came with the stereo and look for acceptable file formats. (Something that says .mp3 or . something.). If it still doesn't work, the pen drive itself may need to be formatted for the car stereo to be able to recognize it. (Maybe FAT32 instead of NTSF). The information should be either in the book or on the manufacturers webiste.

Good luck!

Oops! Well, it may not be such a bad problem. This is what Microsoft has to say about it:
Reinstall Internet Explorer in Windows 8.1 and Windows 8 Because Internet Explorer is now a Windows feature in Windows 8.1 and Windows 8, you can't uninstall it. However, you can turn it off. To do this, follow the steps in the "Turn off Internet Explorer" section in Install or uninstall Internet Explorer (http://windows.microsoft.com/en-in/internet-explorer/install-ie) .

After you turn off Internet Explorer and then restart your computer, Internet Explorer will be removed from your computer.

You can also turn the Internet Explorer Windows feature back on to reinstall it on your computer.

Translation: Why can't I change my screen resolution? (English).

You video adaptor limits the resolution you can choose. If you right click on the desktop you can pick the graphic settings you want and it will give you 15 seconds to see what it looks like, before it restores to what it is already.
