Problem with power

I just changed my old Power Supply from a Mustang 350w to a Fortron 400w and from a crappy heatsink to a new Volcano 12 Extreme. After installing, I plugged everything in to boot my computer, and the new heatsink worked perfectly (as well as the speed adjuster that it comes with), but the Power LED that usually comes on didn't come on, and my screen was blank. My PS2 mouse and PS2 keyboard wouldn't respond (and they should normally, right? even if the monitor's blank and not showing anything, I should be able to plug in my keyboard and tap CAPSLOCK and see the green lights come on and I should be able to see the red light under my optical mouse on, right?)

Afterwards, just to make sure it wasn't the power supply, I plugged everything from my old power supply back in like it used to be, powered it on, and got the exact same problem, so it must be something I messed up on in the whole process.

Also, on a minor note: I pryed off the back panel (metal part of the case in the back that is around where you plug in the ps2 mouse and ps2 keyboard and the sound and usb devices and sound devices) and I was somewhat rough with it, but the most damage I think that would have done would be making my PS2 devices inoperable, but I might be wrong.

Could it be that I didn't install the new heatsink and stuff correctly? I looked at guides for using thermal compound correctly and my stuff looked fine. I used 70% isopropyl rubbing alcohol and a cotton pad to remove the compound. I messed up a few times when I was installing the heatsink so I had to remove what thermal compound was there once, I don't know if that's much of a problem either.

my system is the following:
amd 2800+ athlon xp barton
soyo kt600 dragon plus
1024 (2x512) mb corsair value ram pc3200 (but it's running as though it's pc2700)
120gb western digital hard drive
fic radeon 9600 pro 128mb
fortron 400w power supply (used to be mustang 350w as noted in post)
volcano 12 heatsink and www.arctic-cooling.com's "Silicone Paste" (used to be crappy thermaltake heatsink with the thermal paste that comes with the motherboard)

thanks a ton for reading, feel free to ask any questions about my computer and I'll try my best to answer them

is there a fan lead going to the fan plug on the m/b? some m/bs won't start up if there is no signal there

bump: my cpu fan is now not working at all anymore. I took it off the CPU FAN 1 dipswitch and put it on CPU FAN 2 to see if it did anything, and it stopped working, and I had to grab tweezers and pliers and a bunch of junk to get it off CPU FAN 2 because it was stuck, and now that I finally got it back on CPU FAN 1 it's not working. I'm about to shoot myself guys :|

Either I just messed it up badly by trying to pull it off over and over, or when I switched power supplies and stuff earlier I forgot something and didn't notice that the CPU Fan stopped working, which I truly hope is the case.

Please help me guys, I'm at a loss for ideas and I really don't want to have to spend more money on new parts :(

EDIT:

I messed around a little and now the CPU fan is working fine again. Disregard this post :D

but is the machine working yet? can you get into the bios?

also can you put a link up to exactly what you got for the hsf and fan speed control unit?

just want to know exactly what products you have. also have you tried unplugging the machine for 5mins, and while the machine is unplugged clear the cmos and then reconnect the power and try that? also if you turn on the monitor, i am assuming the led on the monitor tells you that there is no signal, like blinking or turning amber. if when the monitor is on and alerting you that there is no signal and then you turn on your computer does the monitor led ever change?

" just want to know exactly what products you have. "

they're posted earlier in this thread, unless there's something specific you see that I haven't mentioned, in which case you should let me know what that is.

"also have you tried unplugging the machine for 5mins, and while the machine is plugged in clear the cmos and then reconnect the power and try that? also if you turn on the monitor, i am assuming the led on the monitor tells you that there is no signal, like blinking or turning amber. if when the monitor is on and alerting you that there is no signal and then you turn on your computer does the monitor led ever change?"

I tried clearing the CMOS, it didn't do anything. For my monitor, it just stays blank. No signal or anything :

What worries me is that my PS2 keyboard/mouse aren't lighting up or responding...hopefully I didn't mess anything up in there.

Any other ideas as to what could be going wrong?

can you put it all back the way it was, with the old psu and hsf, and take out anything you added? maybe that will eliminate something that is new....
