Emachines EL1850 had the cpu Celeron single core which sucked for gaming because it slowed down or even froze on its graphics,Ive bought a socket 775 Intel DUAL CORE Duo 2(3.00ghz) CPU upgrade chip from Ebay as a performance upgrade to replace that worthless Celeron, but need to know how to install the dual core using the CMOS reset procedure because the ACER support website said my machine is too old for support Of course its old, im not spending an additional $300 to buy newer machine! Less than $150 was spent for the 480 Watt power supply which was $30 Ha! and only $25 for an Asus PCIexpress graphics card having 1 gig with both the analog VGA and flatscreen DVI ports. That Intel dualcore Duo 2 (3.00 ghz) was only $25 on Ebay, proves you dont have to spend like $300 for a machine when upgrade the thing yourself. All I want to know is how to set the CMOS to yank out that Celeron crappy CPU to install the better Intel dualcore Duo 2... getting parts on a budget isnt so difficult people, its the proper installation that is the problem, wouldnt want to *fry* all that effort in 1 shot now do we ?
