My attach iss not working in my e-mailI pressed something and now it won't load

test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your ((motherboard to your hard drive)) Ide/Sata make sure they have a secure connections and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?

even something as small as an electrical extension or a faulty fan lead can cause this problem

a computer needs all of the data and electrical current to travel through every working device and to have an end for a computer to be able work properly
make sure your graphics card is securely seated with no dust in its socket
Restart your computer
During the boot process you will see on the screen to press a certain key to enter setup
Press and hold that key during the boot up process to enter BIOS you can load failsafe defaults or load optimized defaults ,press escape then press f10 to save to cmos to restart
hope this helps you
