My last PC-silencing project failed badly yesterday.
At Sunday I had fully working PC, but today it won´t even
boot up! The project started to replacing Enermax 350W PSU
with Q-Technology Ultra Quiet 300W and also replacing
ordinary cables with rounded IDE cables + new Papst Case fan!
The first problem that there weren't enough molex connector
with new PSU... what the heck! Ok, I left one HD without
power conncctor (was it mistake!)and after all was installed
tried to boot up PC!!! You should have seen my face!!
The power was up leds blinked and fans were rolling, but
no booting and the monitor screen was dark. Tried and tried
it again, but with no luck. Then I tried to put old
Enermax PSU back to PC to recover situation. I think
all were connected properly, but no boot up only
PC speaker; beep,beep beep...
What went wrong? Isn't Ultra quiet 300W enough for my PC?
I have Athlon XP2000+/512 DDR 266 RAM, EPox 8K7A+ mobo(AMD760),
3 HD; 60 Gb Seagate Barracuda IV, 20,4 Gb older Seagate Barracuda
7200 rpm and 17 Gb Seagate Medalist 5400 rpm (boot up disk),
Matrox Millenium G200 16 MB AGP, SW1000XG soundcard!
 
The Addition!

I checked juat now from Epox site that Post Led Code C1 is memory error;
inserted wrong, compatilibity problem and memory can be bad.
In fact, I installed yesterday second 512 MB ddr RAM chip and I think
I installed it properly, but maybe still somethin was wrong? I even took out
new RAM and left the only old one ( which was working properly) but
same beep and post code C1 still !
 
Mace, it is really important here that you change back everything to how it was to try and find the fault. So firstly put old PS back and remove extra memory stick. If it still doesn't work pull Mobo out of case and place it on insulating foam. Connect just PS and video card. Now switch on mobo each time by shorting the two power on pins. Swap out every component until you find culprit. (You will need another mobo for test purposes here).
 
Good advice!

Yes,
Yesterday I actually removed extra memory stick, still beeping
and same pst code C1-memory fault. Would rounded IDE cables be
problem, just have to check it today with original cables; same combination
that worked at Sunday. Have to check AGP card too, because there was no
oicture at all yesterday!
 
To begin with just forget connecting any IDE cables. It is unlikely that would be the problem. Concentrate on mobo, PS, memory and AGP video card. Swap out PS (done), memory (done), AGP video (yet to do), then mobo itself. Looks like either video or mobo at fault but maybe you need another stick of memory (earth yourself with an earthing strap whilst you touch it.) Another idea! Try resetting the bios by shorting out the appropriate jumper. Also removing/reinserting the processor sometimes resets the mobo.
 
Huh... it was peace of cake at last!

Ok'
I am little bit relieved now, cos it wasn't so serious after all.
Memory stick wasn't pushed properly to bottom, althought it looked alright.
You must use so heavy force with sticks and you're afraid of bending
mobo too much! But I'm happy that now it works.
 
I always change only ONE peice of hardware at a time to avoid problems like this.
