Okay I know you guys are tired of all the drama as i am with all these different pcs. First thing first, power supply with the msi was all ready going bad found out when i pulled it to put in an acer. So i need some reccomendations on the best but least expensive 650w psus. SECOND: the dell has been retired. THIRD: i am now using an ACER Aspire ASE360-UA421M pc. Will be updating my pc specs shortly. The mobo is a FC51GM with a Manchester 4200+ athlon 64 X2cpu, 939 socket. On board graphics is Nvidia GeForce 6100 and currently has 512mb x2 hyundai ram. The mobo has 4 sata connectors and 2 dual IDE connectors and currently has a sata segate 250gig hdd with and IDE dvd/rw on primary Ide 0. Now the questions. I have 2x 512mb micron ram with the same specs as the installed ram which is pc3200 @ 200Mhz.Can I use these with the installed ram and which one should be in slots 1 & 2?? next question, the person to whom i gave all my pc parts to said that if the ati x700gpu would work in the acer that he would give it back to me. Will it work and should i use it or stay with the onboard gpu. Third and last. I have pulled my 320 and 500 gig western digital hdds out of the dell, that are only data and has my music and games on them. Since i have never had a pc with a sata hdd as the master how would i go about installing these and where would the jumper pins go. I was told something about having to go into advance bios setting and doing something with the scsi (something or another). Just as soon as I get all the hardware installed and configured i will update my pc stats. Local pc shop said they can get me a biostar mobo with amd 7750BE cpu for $90.00
