Hi,
You can check the hard drive and the RAM to make sure that they are connected properly. Remove the panels in the back that cover the hard drive and RAM with a small Phillips-head screwdriver. Press the components firmly into their connections. This step is not recommended due to damage in customer device risk.
Check your computer’s temperature. Overheating can lead to your hardware malfunctioning. One of the most common components to overheat is the graphics card. In BIOS post test the computer shows on black screen at start up the temperature conditions of computer box. To check it customer can restart the computer and on first screen top right or left corner will show the information of temperature. If it is more than 40 celcius then it is more likely to crash the computer. Reseat the computer in a more cooler place i.e top of the table and away from the wall for venting purpose. The malfunction of processor fan can also be the reason.
Test your RAM. A common culprit in system crashes is a bad stick of RAM. When RAM fails, it causes the system to become unstable. Open the box unplug it from the Slot Remove the RAM clean it for carbon and dust particles and plug it back on make sure when you plug it back you hear the click sound.
Test your hard drive. Run the “chkdsk” function on your hard drive to scan for errors and fix potential problems. A failing hard drive can cause Blue Screens due to corrupted files. To run chkdsk, open command prompt and type CHKDSK entre.
Good Luck
