It's not good. It could cause a short circuit which potentially damages the motherboard and other components attached to it. http://www.pcstats.com/articleview.cfm?articleid=1720&page=7 Hopefully you've got away without causing any severe damage.

errr. yes!

you only put the standoffs under the holes where the screws go through to secure the mainboard.

Pretty much one in each corner, one at the half way point under the long edge, and sometimes one of two near the memory slots.

DIY computer builds can be OH so expensive if you don't know what you are doing.....:rotfl::rotfl::rotfl::rotfl:

You probably killed the MOBO when you blew the PSU to smitherines.....:beer:
Like everybody keeps saying on here, "It's easy peasy, just like putting lego together".......:j
Made my day thank's....:D#

P.S. Did you have a puff of blue smoke or a puff of grey smoke out the back of the machine when it blew up????
It makes no difference realy, I was just curious...:P

Like everyone has said, I'll try to summarise it and some basics....

Use brass stand offs always, shorts on the motherboard can cause electrical problems (possibly what you've seen) and also problems like rebooting computers

Swap the PSU for a good one (you can also test yours with a multimeter) later on

Since the PC isn't booting, I'd take everything out the case, disconnect EVERYTHING except the CPU, CPU Fan and Memory. Put the M/B on a wooden bench or a cardboard box (shoe box). Connect the monitor to onboard VGA and power it up, if you get a display with onboard VGA, there's a short somewhere or a faulty component (VGA card, IDE controller, etc). If there's no display whatsoever you have (duff mem, duff cpu, duff m/b, duff psu)

That's why it's always handy to keep spares when you fix computers for friends and family, great for testing purposes :D

EDIT - Also btw, most cases have marks for the type of motherboard stamped on the inside of the casing (i.e ATX, EATX), normally you put the brass stand offs in these and you should find they will match up, it's usually the same 1 in each corner and 2 in middle.

Good luck!

Oops, wrong thread!!

I meant to say, I bought a new motherboard, swapped the memory and processors and tried it all again. IT WORKS!!

Runs at 27 degrees C now, and is nice and quiet. Huge, doesn't fit under the desk, but it works. I'm so proud

Thank you all so much.

Well done. everyone has to start somewhere, sounds like you have learnt an awful lot during your first go :)
