Hi, (I apologize for my bad englisch) I wanted to upgrade my CPU so I bought a i5-3470, when I put it on the motherboard I only get 4 short beep sounds. I thought that the new CPU had issues so I put the old one back and now I have a constant beep with this one, it is a i5-2310. The motherboard is from a Acer AX3960 computer and some other components that I have are the power supply 650W from GameMax, GTX 760 from Zotac, 1 Tb Seagate HDD, 10 Gb ram (4 Gb Hyperx and 6Gb Kingstone, all are DDR3 1333Hz). So far I tried putting the new CPU on the motherboard and reset the CMOS by removing the battery, re-plug the RAM one by one, re-plug the Gpu and the Hard drive but nothing works. The old CPU that previously worked without any problems now doesn´t work either, I also tried to solve the problem with the same steps as before but it didn´t work. Does anybody know how to fix it? The computer turns on but I don´t get any image, so I can´t make changes in the BIOS.
