So i was trying to replace my Intel Dual core 1.8 ghz really old with the Pentium E5300 2.6 Ghz. http://www.newegg.com/Product/Product.aspx?Item=N82E168... Once i replace it with the Pentium it boots up everything lights up. it runs but the display has no respond. No signal no nothing. Then i put back the Dual core then the monitor works. The spec for my optiplex 745 is 300 watts-350 watts 2gb ram intergrated graphic. So maybe it's my watts?
