Will not start up


hi , Reuben

I would suggest you try safe mode.
Safe mode is a troubleshooting option for Windows that starts your computer in a limited state. Only the basic files and drivers necessary to run Windows are started. The words "Safe Mode" appear in the corners of the display to identify which Windows mode you are using. If an existing problem does not reappear when you start in safe mode, you can eliminate the default settings and basic device drivers as possible causes.
If you don't know the cause of the problem, you can use the process of elimination to help you find the problem. Try starting all of the programs you commonly use, including the programs in your Startup folder, one by one, to see if a program might be the cause of the problem.
Follow the steps to boot the computer in safe mode with networking:
1. Restart your computer if it is powered on.
2. Tap the F8 key after your computer initially powers on.
3. Once you see the Advanced Boot Options menu you can stop tapping.
4. Use the up/down arrow keys to highlight your selection.
5. Select Safe Mode with Networking and press Enter.
6. You should see drivers loading, and then please wait.
7. You should then be at the Welcome Screen.
8. Logon to your computer using an account with Administrator privileges.

Are 2002 Aztec computers compatible


I am assuming you are discussing the 2002 Pontiac Aztec, the early crossover with the rather distinctive look. I would assume that since they were made by the same manufacturer and they used the same parts that their computers should be compatible. I can't say so for certain as you haven't provided much information, but, unless one of the Aztec owner swapped out the original computer and replaced it with an updated device, the computers should be compatible.

If you are thinking of trying to swap computer chips, I would advise you to wait and let a professional do it at an independent shop. The reason I suggest this is simple, unless you know how to access the computer chip correctly, you risk accidentally ruining it. If you handle the replacement chip incorrectly it is entirely possible that for a stray static charge to ruin the chip by blowing out a trace. Also, if you damaged the socket from which the original chip was removed then it is possible that you will not be able to reinsert the new device without bending any leads on the bottom. If the leads are damaged, then the new computer won't work.

Even if the new computer chip and the original chip were already installed in installable cases (the way most desktop computer chips are installed), it is possible that when you removed the computer, you might have damaged the receiving socket which means that when you go to insert the new computer carrier it won't work correctly because a few or many of the pins on the bottom of the board won't sit correctly.

How to enable bluetooth


Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

Screeen is upside down


If you have a Windows OS, press and hold the ALT and CTRL (control) keys and then press the Up arrow. (If that doesn't work, try holding the Alt and CTRL keys and pressing the left (or right) arrow key twice.) If that fails, right click on the desktop (Windows+D will minimize all programs), anywhere with no running programs or icons. Then select the Screen Resolution option. Look for the line Orientation; use the drop down menu to select the correct orientation. Click Apply and then confirm the setting change if a confirmation window pops up. (This works in Windows 7 and 8.) For older Windows versions on laptops, you may need to select Graphics Properties (or a similar line) and then repeat this. The Windows screen rotation option is dependent on your video card. With some models, you'll need to open the graphics card properties to undo the rotation. You should see a line for the graphics adapter when you right click on the Display.

For Macintosh OS, make sure that the System Preferences is closed. Then open it by pressing Option/alt + CMD . Select the line Display. Find the button labeled Rotation: Standard then choose the correct screen orientation.

I hope this helps.
