A few troubles.

post #1 of 5
Thread Starter 
I bought a GeForce 7900GS OC, and 1gig of Kinston PC5300 memory, and got both of them today. I screwed around with the memory until it would load the logo screen of turning on, and then put in the Graphics card. When I put in the card, it would get to the loading screen, and the only thing I could do was enter the BIOS. I did that and configured it a bit, but then it restarted and froze at the logo screen. (An e for eMachines, showing "Hit F2 for Setup" & "Hit F10 for Boot Options"). I double checked everything, and realized that my PSU was only 300W, and 15A on the 12V rails, and the requirements were 350W with 22A on 12v. So I figured, Ok, I have to buy a better PSU then.

So I took out my graphics card, and then hooked up the VGA cord to the regular mobo hookup. I turned on the computer, but the screen was all scrambled. I couldn't figure out why it was doing this, but I took out the 1gig of memory and replaced it with the other 512 stick I had. (The standard for the computer was 2x 512mb). How can I fix either of these problems, and what PSU would you recommend? (Probably a 450W I assume)

Sorry for the long read, and thanks for the help. I'll check back later to discuss.

Edit: The system uses Windows Vista Home Premium as an OS, and BFG is the manufacturer of the graphics card. (Kingston is for the Memory, as stated above)

Awake, here's the PSU that I have: http://www.newegg.com/Product/Produc...82E16817151034

Seasonic makes quality power supplies. Excellent efficiency. There are others out there that are just as good too.

So if I understand you correctly, you can't get past POST? (power on self test)

Yeah, it'll freeze at POST. Occasionally it'll flash, and the screen will go black, but that's where it stops completely.

Edit: Is it possible to get a PSU under 100? I see most of the 450W ones are, but most of them don't run at the rating I need. So I guess I'm gonna need a 500W, which I can do, if I need to. Also, is it better to get the Dual 12v, or not?

Awake, from what I heard and read, it sounds like one 12v rail with high amps is better then two or even three 12v rails. A lot of those power supplies seem to be up in the 600watt and up range. I'm not sure if you need that much but you never know, you may want SLI down the road . A 500watt should be fine for you, even a 400watt will work. Just as long as the +12v rail/rails are at least 28-30amps combined. If you ever do SLI I recommend something higher then 500watts.

What brand 7900GS do you have? Do you another pci-e card to test with? Did you plug in the 6-pin molex power connecter? It very well might be your psu causing these issues.
