Is your PC not turning on? Yesterday we were assembling a new ASUS PC. The power supply had all the relevant components connected to it, however, when turning on the power switch, nothing happened! There was only a faint blinking from the standby power (SB PWR) switch, shown below:
We then disconnected all components that are not necessary for booting the PC from the motherboard, so we just had the basic things connected to the power. Alas, we still had the same problem.
After trawling through many tech blogs we could not find the answer to the solution..there was talk of the motherboard not receiving enough power, and that something connected to it was causing it to short circuit. However we only had the necessary things attached to the power source (motherboard, pwr switch and CPU fan) so we couldn’t see what was causing the problem.
We then noticed that the motherboard didn’t have stand off screws. The motherboard was screwed directly into the base unit, causing the screws to conduct electricity from the power source – causing the motherboard to short circuit. Applying the stand off screws to the motherboard ensures isolation from the base unit and decreases the chance of short circuiting.
A quick resolution to this problem is to check that your motherboard has stand off screws.
Wireless keyboard and mouse interference can result in lag. While working on your laptop or computer, you may find that your wireless keyboard and mouse become unresponsive, stuttery and laggy. This can be very infuriating, but here are some steps to help resolve the problem.
A common cause of wireless keyboard and mouse lagging is a result of wireless interference from USB 3.0 devices, such as external hard drives and other USB 3.0 removable media. Interference may produce the following symptoms:
- Delayed keyboard and mouse inputs
- Ignored mouse or keyboard inputs
- Decreased wireless range between the mouse/keyboard and USB wireless receiver
Reduce wireless keyboard and mouse interference
- If your PC or laptop has USB 3.0 (SS) ports, connect USB 3.0 devices in these ports. Then plug the USB 2.0 devices such as the wireless receiver in the USB 2.0 ports, giving as much distance away from the USB 3.0 device as possible. For instance, if your laptop has a USB 3.0 port on the left, plug in your external hard drive there and if there is a USB 2.0 port on the right, plug in your USB wireless keyboard and mouse receiver there.
- Ensure that your wireless keyboard and mouse receiver are positioned as close as possible to the keyboard and mouse.
- In situations where you are unable to create much distance between the USB 3.0 and USB 2.0 devices, use a USB extender cable to increase this distance.
