Can't see the letters on the keyboard

by PD Malcom on 1/29/2014

Having a bunch of problems setting up computer and downloading Windows 8.1. Still don't have speakers working. The biggest problem is the keyboard has letters/numbers that are just barely visible. Not being an expert typist makes it impossible to read keyboard except in direct bright light. Still trying to figure out if this is normal or I have a bad keyboard.

ASUS M51 Desktop PC equipped with the latest 4th generation Intel® Core™ processors and NVIDIA® GeForce® GTX graphics for smooth multitasking and high-performance gaming. M51 desktops also feature ASUS Smart Cooling technology for cooler and quieter operation, and ASUS Power Pack — a removable UPS (Uninterruptible Power Supply) that can also be used as a portable battery recharger for smartphones and tablets. In addition, the M51 is its first desktop PC to feature ASUS SonicMaster audio technology for enhanced sound quality.

Horsepower at Your Command

Fulfill all your imagination for a desktop

Next-generation processor
The latest 4th generation Intel® Core™ processors deliver new levels of multi-tasking performance to make light tasks of even the most demanding tasks, from playing 4k UltraHD video, editing high-resolution photos to playing the latest games at their maximum quality settings — and everything in between.

The Force Shield Experience

Leading in satisfaction with reliability
ASUS computers reflect a tradition of the finest quality, innovation and longevity. Based on the PCWorld USA 2012 reader survey of tech satisfaction, reliability, and service, users ranked ASUS as a leading choice for desktop PCs, citing high satisfaction with their value, connectivity, ease of use and reliability. The survey also found ASUS desktop PCs were one of the most likely to be recommended to others.

ASUS Power Pack
ASUS Power Pack is a mobile charge station that can charge devices on the go. When plugged into the desktop, it acts as an emergency power supply keeping the desktop powered for 25 seconds if there is a sudden power loss. If a power cut last longer than 25 seconds, it will enter hibernate mode automatically so that no important data is lost.

Engineered to be cool and quiet
The exclusive ASUS Smart Cooling System reduces dust accumulation, lowers operating temperatures by up to 11.4?2, and adjusts CPU fan speeds according to its current load for stable, reliable operation.

The best motherboards in the world
ASUS desktop PCs are built on the best motherboards available — and we should know, because we make them. We’ve sold 465 million motherboards since we first started making them over 24 years ago and our models won over 1,000 awards in 2012 alone.

Factory-tested for perfection
ASUS desktop PCs are subjected to a series of rigorous tests to ensure they meet our exacting standards — and exceed those used by other manufacturers. So you can rest assured that your new computer can cope with everything from extreme temperatures and humidity levels, to the demands of being shipped around the world.
