I have a Dell dimesion 4300 here and I cant get it to post. This computer belongs to my Aunt and she brought it here for me to take a look at since I am the only "computer guy" she knows. Anyway she said one day it stopped working, I asked her what happened and she said one day it just would not turn on. Well I have it here and went through the usual, I disconnected all the drives and left only the hard drive, video and RAM, still no post no beeps nothing. Next I tried it with no RAM and got some error beeps, tried the RAM in a different slot and nothing. Next i tried swapping power supplys and still nothing. I am thinking well it must be either the video card, motherboard, and CPU or maybe memory. Im not sure where to go from here im kinda stumped and I dont own any intel/P4 stuff so I cant try to swap those out, I have my Geforce3 video card BUT im not going to stick it in there and risk screwing up my $200 card. There are four lights ont the back of the computer right above the keyboard/mouse ports that are flashing green and orange I have to assume its some sort of error codes but I cant find any info on the Dell website, I cant even figure out who made this motherboard for Dell, hell I cant even find a clear CMOS jumper on this board. Well my first experience with a P4 hasnt been fun, any help or sugestions is appreciated thanks.
