Hi, I bought recommended Crucial ram lately, I got the ram today and I tried installing it, after putting the sticks in my monitor displayed "No Video Input", I then tried each stick individually, which gave me the same results. Strangely enough after I put my original ram in, the pc booted up normally. I have an ASUS M4A785TD-M EVO motherboard, running AMD Athlon II X4 630 on Windows 7 64-bit, the ram i bought was 2x4GB crucial 1333mhz unbuffered
