Hi

The supported Memory types for Dimension 2400 Series is PC2100 (266-MHz) or PC2700 (333-MHz) DDR SDRAM (non-ECC). Supported Memory capacities are 128, 256, or 512MB and a Max if 1GB (1024MB).

The first obvious question is does the new 512MB Memory module meet the above specification? Some Memory modules are able to steep down speed.

If it does, then first ensure the new memory module is properly installed. Take ESD (ElectroStatic Discharge) precautions or you may damage the new memory module and/or the system board.

To proceed compare the system beeps and diagnostics lights color and sequence to the Advanced Troubleshooting guide.

It is possible that the new memory is DOA (Dead On Arrival). Or there is a new fault on the system. If you have access to another compatible system, you may test the new and old memory modules. You may also swap the new and old memory modules to determine if the memory slot is at fault.

Lastly, if you remove the new memory module, does the system complete POST (Power On Self Test)?. If it does you may indeed have a DOA or incompatible part.

Can you upgrade cpu in dell 15 i5559-4682slv to i7 ?


It is almost impossible to upgrade proprietary makes like Dell and HP. The are big enough to have motherboards made for them manufactured on price point. This means that they are not built with upgrade in mind. Also the cases are made to fit their motherboard and theirs only.

Go to a computer builder and get a good case, buy a good quality motherboard and equip it with what you can afford. In two years you can upgrade as processors have moved on. Two years after that, you can swap out the motherboard, processor and memory.

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.

How to install bluetooth on my pc


Hello,
This depends on what kind of bluetooth you plan on using. Certain things like a Blu-Ray DVD Drive needs to be installed and hooked up internally in your PC, while something like Headphones or a Keyboard simply just needs a USB-based transmitter or a Bluetooth card that plugs into your computer.

Hope that helps,
