So i've been having a lot of problems with my pc. all of a sudden when i turned it off and back on afte rmoving cables i recieved no display. at first it was hard to find otu what the problem was since my antec 900 case doesn't have a speaker for the beeps. i got a new vid card, evga 9800gtx. it worked for a little bit, then stopped. i changed the mb battery, worked a little. i sent the mboard in rma. i just got it back. it plugged in everything and it doesn't work! i took the ram out, cleaned it. plugged in a comp speaker from another tower, put one stick of ram in. the computer was stuck at the post screen. i reboot and i went to bios and changed a few settings. and then the computer was fine. i could use my computer. then i put the other stick of ram in. and then no display and no beeps. i took it out and then it worked. i thought it was one bad memory stick. i swapped them, didn't work. and then i tried the workign one and then it started to not work. i took both ram out and then i got those beeps meaning there is no ram in the mboard. so i'm not too sure if it's the ram that is bad and if i should get new ones or not.
