It may be your memory sticks/cards. I had that problem and took it to the shop and all they did was move the memory sticks down 1 slot. the 1st slot was bad. This will take some detail of removing the skins on the desktop. Hope this helps.Dave

try to unplug it fromt he back of your pc and open the side of your case and unplug the 2 or 3 onnectors going fromthe power supply and wait 10 or so minutes amnd plug them back in and see if that changes it if it powers back on that meant it has shut off either due to a short circuit and the system killed power to protect the system from damage or the system has overheated

That link is a video of how to take apart yor case. It is very thorough, primarily, it just shows that the side of the case is held on with a couplw of screws, looking at the tower from the front, it's the left panel that you want to remove, not the left, the right one will give you access to what yo are interested in doing.Make sure the plug is removed not just turned off. There is residual voltage that still runs into the main board from the power supply, and try to use a very light computer vacum or one of those swiffer dusters work well. If you poke around with the vacum be careful that you don't **** off the jumpers, you won't relise it untill you turn it on. You can use compressed air that is sold in computer stores or most large electronics stores like Best Buy, Don't forget to get the power supply in thr upper corner of the case, it also has fans in it that collect dust. When you re assemble it, make sure you get the panel in the groove at the bottom, and the clips at the top, and good luck

This video shows you how to restore the BIOS in your computer:

You can follow the steps in this video to troubleshoot your battery:

1. Central Pin: In many laptop power supply connectors, especially those using the barrel-type connector, there's a central pin that carries the voltage (typically around 19 volts for most laptops) to power the device.
2. Voltage and Polarity: It's crucial to ensure that the voltage supplied by the power adapter matches the requirements of your laptop. Most laptops operate on 19 volts, but there are exceptions, so always double-check the specifications of your laptop and the power supply.
3. Polarity: Additionally, the polarity of the connector is important. The central pin typically carries positive voltage, while the outer sleeve of the connector is the ground (negative). Reversing polarity can damage your laptop, so make sure the connector is inserted correctly.
4. Safety: Always use the power adapter that came with your laptop or a compatible replacement from a reputable manufacturer. Using an incorrect or incompatible power adapter can not only damage your laptop but also pose safety hazards such as overheating or electrical fires.
5. Replacement: If you need to replace your laptop's power adapter, ensure that the new adapter provides the correct voltage, polarity, and wattage for your laptop model. It's often safer to purchase adapters from the laptop manufacturer or certified third-party suppliers to guarantee compatibility and safety.
