help I'm an idiot..whats this black stuff ontop of the processor
Ok, so the mobo (nf7-s) is insulated around the mounting holes so I
can screw it directly to the mounting plate right? Ok, so there was a square of blacy rubbery stuff on the copper part of the cooler I got. I haven't had any luck getting the system to run so I took it back apart to check the processor. amd xp 333fsb Now some of what I had assumed to be thermal tape has rubbed off on the chip in the center of the processor (which I had noticed some discoloration in the ic around the main chip) is it possible the chip was already dysfunctional? is that thermal tape I am talking about? -- We are Many Mark 5:9 |

link.net... Ok, so the mobo (nf7-s) is insulated around the mounting holes so I can screw it directly to the mounting plate right? No - you have to use the hex, spacer screws. Fix them into the case and screw the motherboard into them. If any part of the motherboard is touching the backplate, then you will short the board and at best, the machine will just not boot, at worst, will smoke and go on fire! Ok, so there was a square of blacy rubbery stuff on the copper part of the cooler I got. Sounds like there was black plastic film protecting the cooler from being contaminated with dust and dirt. The protective film might have been over a thermal pad or just protecting the nice shiny heatsink surfase. Pad or no pad you should remove the protective film before subjecting it to about 50 degrees of metal-to-metal heat! Removing the black protective film should reveal the thermal conductive substance or a nice shiny heatsink surface. Sounds like you left on and have melted the protective film (onto the CPU)! Unless the CPU has overheated and been damaged, the plastic should clean off and maybe the CPU will be OK?! I haven't had any luck getting the system to run so I took it back apart to check the processor. amd xp 333fsb Now some of what I had assumed to be thermal tape has rubbed off on the chip in the center of the processor (which I had noticed some discoloration in the ic around the main chip) is it possible the chip was already dysfunctional? is that thermal tape I am talking about? Does sound like some kind of thermal compound, perhaps tape or thermal pad. I would suggest that you clean everything up, space the motherboard away from the metal (conductive) case and then install the CPU again. DO NOT run the CPU without the heatsink - it will fry within a few seconds. You might need to buy some conductive compound to use between the heatsink and the CPU. If nothing works, then you may have a faulty motherboard or CPU. Who can say if they arrived faulty or not though! |

You are making mistakes that can damage your hardware and maybe damage
you. I suggest the following may help: http://www.pcmech.com/byopc/ http://www.motherboards.org/articles...des/924_1.html -- Mac Cool |

Hell no, you MUST use spacers between the moterboard and the plate. If you dont, the board will either fail to work, or be permanently damaged.

Now youve removed it, you need to reapply with a new pad or thermal paste. Do not power without theh eatsink or *new* interface material My advice is take it to your local Pc shop, or someone who knows what theyre doing before you kill it completly. hamman |

"legion" wrote in message link.net... Ok, so the mobo (nf7-s) is insulated around the mounting holes so I can screw it directly to the mounting plate right? Absolutely NOT !! There are small brass standoffs that screw into the case. Then the motherboard is attached to the standoffs with phillips screws. If you just sit the motherboard on the floor or side of the case, you will short out the motherboard as soon as you apply power - and probably ruin other components as well. Read up on motherboard installations. Ok, so there was a square of blacy rubbery stuff on the copper part of the cooler I got.

Read up on motherboard installations. That's what I was thinking. I've got a system I built about 5 years ago ( AMD K6II 450 ) and the back of the motherboard has round soldered areas (silver circles) that are pressed down against those standoffs with no insulators on either side. It provides a ground plane. I've checked the round soldered areas with a digital voltmeter and they're common with the ground of the power supply connectors. But you do have to be careful, if you install the motherboard off center you could press a trace that's carrying a positive voltage against one of the brass stand offs and cause a short. You also will have to install plastic standoffs to help prevent flexing of the motherboard when you install video / sound cards , memory sticks etc. Just my experiences. HTH Gary Snip |

I didn't get any hex, spacer screws. so I fabricated some spacers out of leather scraps, and insulated the top and bottom of the hole where the screw goes. The mobo power light came on but nothing happened when I pressed the switch. At least before the fans would spin so I took the spacers out and tried it just screwed into the tray, and still nothing. I have everything put away for right now, untill I get my new psu and I can find some mounting hardware. I cant see anywhere the mobo might of been damaged more later |

I didn't get any hex, spacer screws. They should have come with the case (or maybe the motherboard). so I fabricated some spacers out of leather scraps, and insulated the top and bottom of the hole where the screw goes. Sounds like a fair thing to try - but if you have already shorted out the board, nothing will work?!? The mobo power light came on but nothing happened when I pressed the switch. At least before the fans would spin If the board has been screwed directly onto the metal backplate, then contacts will have been made on the underside of the motherboard that should not have been made and something will have shorted out - unlikely that it is the power supply, but maybe you have been lucky and a fuse has taken the load! so I took the spacers out and tried it just screwed into the tray, and still nothing. No, that is because you have screwed the motherboard straight onto the metal back plate - everything underneath is touching metal and shorting out! I have everything put away for right now, untill I get my new psu and I can find some mounting hardware. I cant see anywhere the mobo might of been damaged I don't suppose there is anything to see - I am not talking about noticable physical damage, more likely small bits of electronic wizardry will have been damaged. more later I'll keep my fingers crossed for you... |

HTH Gary Some cases have raised nipples (or whatever they are called) with threaded holes at each mounting point where the mobo can be screwed on directly without using the more usual brass stand-offs. If the OP just happened to have one of those, it just might be possible that he hasn't damaged his mobo yet. |

Correct!
I have the raised nipples, I did know better then to just let the neat **** along the botom of the board short out, I was just unsure about screwing to the nipples without (plastic or fiber)spacers and it was working when I did, now NOTHING! anyway i might of fubar my cpu cleaning it keep up with my antics in the new post! -- We are Many Mark 5:9 "Zotin Khuma" wrote in message m... gary wrote in message . ..
