Hi guys I have been having problems with my computer all day. here are my specs Gigabyte b85m-ds3h Intel Xeon e3-1231v3 Gtx 1070 16gb (2x8) g skill ram adata ssd wd blue hdd evga 500w psu
I've been trying to troubleshoot for almost 12 hours on my day off My computer this morning would not boot when i turned it on. no power or anything. I found out my evga 1070 would make my buddy's computer act the same way. So i took it back and got an asus strix 1070. Now when I plugged that in, the computer beeps once, and stays on but there is no signal to any monitor i hook it up to. I have no on board graphics to change bios settings. I have changed the psu with a brand new 550w antec, replaced the motherboard with an identical brand new one, booted with only one ram stick in all slots, reset cmos battery, made sure all cables are plugged in and i still have no clue i am so lost and im out of ideas any help would be much appreciated, thank you
