When a new PC blurts start-up issues, a good place to start is the power supply. Check if your computer machine is getting power. To do so, see if there is a fan activity at the rear of the power supply. If the fan is not working then the power supply isn’t working. First, check the wall socket and power strip to make sure that the power is actually being supplied to the computer. If there is power to the outlet, confirm that the input/output lever in the back is set to input. Then confirm that the voltage is set to 110V (USA) or 220V (in other countries). If you have a voltmeter, you might want to consider testing the power supply.
If the power supply is right and fit for your PC then check if the CPU is installed properly. Proper computer installation is important for the functioning of your computer. You can also go over the IDE cables and the thin wires running from the power and reset switches to the motherboard. While the IDE cables are keyed, it is quite possible to get those case wires backwards or completely. Also, ensure that an errant screw did not fall behind the motherboard during the install. This could blow the motherboard or cause the system to go to ground.
Improper installation of the motherboard or CPU can cause instant failure. Sometimes it requires efforts to get the heat sink seated properly on the CPU. The CPU itself should slide effortlessly into place and lock without any problems with the lever. If you require resistance when installing the CPU, make sure the CPU’s pins are properly aligned to the socket on the motherboard. Apply the correct amount of thermal grease or tape as recommended by the manufacturer, then install the heat sink. The heat sink should rest flatly on top of the CPU.
However, if your PC starts but you get nothing on the screen, the culprit may then be the video card. First, confirm the video cable is secured to the video card's output. If the motherboard has built in video, and you’re using a PCI-E or AGP card, ensure that the cable is secured to the correct port. Also, check for bent pins on the connector and confirm the monitor works and the brightness controls are set correctly. As for the motherboard, refer to the manual about each of the connections to the case. A common problem area are the standoffs between the case and motherboard, and the connection of the thin wires from the power and reset switches to the motherboard.
When there is a hardware issue with the CPU, you will often receive a BIOS beep code . You should determine the BIOS residing on the motherboard by physically looking for the BIOS chip on the motherboard. Look for something like AMI-BIOS, AWARD BIOS or PHOENIX. This will often lead you quickly to the source of the hardware problem.
Thus, while these new computer installations can be frustrating, try looking at the problem with a fresh mind. Take a step back and think before you could do more damage. If that also doesn't help, then you can seek technical troubleshooting support from certified technicians who can look into the matter and give instant resolutions. They can help set-up and install your PC, re-configure your operating system, resolve security issues and do much more.
