From: mraloof on 27 Dec 2006 14:38 I decided to switch out my power supply (450W) with a new Rosewill RP550S-2MK (550V) (link:http://rosewill.com/product/product.aspx?productId=378). The Rosewill comes with no manuals at all and I figured I'd just connect the components that need power and connect the motherboard (A-Bit IC7-G Intel Pentium 4 link:http://abit-usa.com/products/mb/products.php?categories=1&model=4) with whatever plugs fit. I made a mistake though. The Rosewill comes with a 20/24 pin power plug for the motherboard and I actually ended up plugging in the extra four pin plug into the motherboard's ATX 12V socket thinking that's what it was for. The machine wouldn't start when it was connected this way though so I kept trying to figure out what was wrong. Eventually, I realized the PSU had come with a separate 4pin cable for the ATX 12V socket. I plugged that in and unplugged the extra 4pin plug and the machine finally powered on. Joy. I headed back to my desk, plugged everything in (USB, keyboard, mouse, monitor, LAN cable, etc.) and powered it on. Everything seemed to start up just fine but it was shortlived. My monitor stays stuck in what seems to be a power-save mode now and I can't get it to display anything. I tried a different monitor and got the same problem. The machine is whirring away, all fans are on, hard drive's making it's noise and seems to be working but I can't get any output on the display. The video card's fan is on (it's an ATI All-In-Wonder 9800 AGP) also. I ended up trying my old power supply and it now yields the same results. Everything seems to turn on but my monitor's stay in a power-save mode of sorts. Does anyone have any ideas as to what could be wrong? Is it possible I somehow hosed the motherboard when I had it incorrectly connected to the power supply? Any ideas or pointers on what I could try or look into would be greatly appreciated. Thanks in advance!
From: Peter on 27 Dec 2006 16:06 the 20 24 pin is for the main connector depending on what mobo plug u have . The stand alone 4 pin is for the seperate processor plug on the mobo idont know what the pin outs but u can find them online. maybe u dint plug your video card in right or you need to reset the cmos removing the power and resetting. gl <mraloof(a)gmail.com> wrote in message news:1167248314.687787.5300(a)79g2000cws.googlegroups.com... >I decided to switch out my power supply (450W) with a new Rosewill > RP550S-2MK (550V) > (link:http://rosewill.com/product/product.aspx?productId=378).

From: aloof on 27 Dec 2006 20:14 Hmm, that's a downer assuming you're not kidding (I don't think you are). Can you help me understand what action you think did it though so I at least learn something out of this experience? Was it just trying to start it with the 4pin connector in the wrong connector? Thanks all...

Also, one more question. Is it safe for me to just focus on replacing the motherboard and try to salvage everything else (memory, video card, drives, etc.)? I ask for two reasons: not sure if you think this fried my processor as well and I can't figure out how to verify that with the equipment I have and, second, I'm not sure how easy it is to get a replacement motherboard that works with all the other parts I have as it's all a few years old now. Thanks again. On Dec 27, 5:14 pm, "aloof" <mral...(a)gmail.com> wrote: > Hmm, that's a downer assuming you're not kidding (I don't think you > are).
