Help! Changed Power Supply, no display on monitor after!

[21Jumper]

Hello Everyone. So we just moved and in the process of setting up my BYO in our new room, I fried the power supply. I know because I smelled something burnt and well, I couldn't turn the thing on after.

So I buy a new one, an Ultra Xfinity 600w. I put it in, connect the necessary plugs to where they should go and I'm able to turn the thing on. With the case open, I can see my CPU fan is on, the led on my NIC is lit, the fan on my GeForce TI200 video card is on, the led by the RAM is also lit and I can open/close my DVD-ROM drive. I can also hear the HDs churning.

But even after all this, my monitor is saying it's not getting any signal. I'm connecting to it via DVI. I haven't tried using the VGA port yet since I can't find my adapter.

Any thoughts on what I'm doing wrong here? Thanks in advance.

Sounds like your power supply may have killed your motherboard when it blew up. The only thing you can try is to clear your CMOS and if that doesn't work, then try removing the CMOS battery for 10minutes and try again.

If you still get nothing, then i'd assume your board is toast.

Thanks for the reply. If that were the case, wouldn't everything connected to the motherboard NOT be working then? But as I stated, RAM LEDs, CPU fan, exhaust/intake fans, GPU fans, and DVD ROM drive are all working. Are those independent from the Mobo's power?

Another thing that I forgot to mention, my keyboard/mouse receiver is connected to the ps2 and usb port on the mobo but those don't power up. Is this another indicator that it's really toast?

I'll try the CMOS battery tip though.

No, fans can turn on even if the motherboard is fried. I agree with daveybrat, it sounds like your motherboard is fried.

Oh crap. Ok, last question. Since it's a foregone conclusion that I'm going to have to get a brand new motherboard, would I still be able to use the CPU on it (P4 2.6) or would it just be better to buy a mobo/cpu bundle at this point?

If you can find a mobo for a P4, it will be expensive. The problem with getting a new combo is whether or not your ram will work. and graphics for that matter. Prepare yourself for the fact that the mobo wasn't the only thing else that is dead. PSU's dying is bad. They almost always take a few things with them.

Yeah I figured as much. I only have DDR for RAM and AGP for graphics and I've been browsing around and it seems like almost everything that's out only has DDR2 and PCI-E.

My videocard was old anyway (GeForce TI200) so I was looking to upgrade, but not like this.

not as expensive as i thought

That should tie you over until you are truly ready to upgrade.

Whoa, not bad. Still have to buy a new CPU though, right? Because I think the one I have is a different socket. And this is microATX. Stupid question #2 - would it fit in the case I have now? Since the ECS mobo I had was an ATX.

It was my first build so I'm not as experienced as some around here.

that is the 775 version of the board i linked to earlier. They are out at newegg, but you can pick one up from fry's or somewhere like that. they are cheap, and surprisingly i have had no problems with ECS. Sounds nuts I know.

Server boards are the biggest and require some of the bigger cases
ATX is the next size. Its pretty standard. Most towers are designed for ATX
Micro ATX is slightly shorter and fits in all ATX (maybe not ALL) cases no problem. when you take you dead board out look for holes on the case that weren't being used and see if it has an M next to it. it should line up anyways though.
BTX is newer and has different sizes and is stupid.
Mini ITX is really small sometimes 6x6 inches and is great for carputers

and thus ends the lesson
