Hi I'm not really to into hardware of a computer. But I'll try to make this clear as I can.

I own a stock Hp a810n Pavilion.

My Northbridge Headsink fell off and the thermal paste is pretty used.
My question is basically. If this happens would that be cause for my psu to rapidly blink?

I checked everything unplugged all power connections and I know my psu is good. once I plug everything in it blinks. I took out my ram and it still blinks (incase the ram was misplaced in there).

Thanks for anyhelp Will check this quite frequently for any questions. For exact mother board specs here is a url.

Asus K8S-LA (Salmon) I believe >__>
Thanks

You need to put the heatsink back on. Buy some thermal paste cleaner and some thermal paste. Clean the old thermal paste off, put some new stuff on and re-attach the heatsink.
It may unfortunately be too late and the northbridge may be dead.

What's blinking on your power supply? The LED on the back of it?

YEah the blinking light on the LED it flashes.

Good article with pics:

Well I'm asking, if the headsink falls off will that cause the led light to blink or do I have another problem!!!

Does the comp load the o/s? If not, then you have a problem.

The blinking light on a psu I haven't ever heard about - look at the manufacturer's site about that.

No nothing comes on The psu blinking light usually means a problem with the psu or ram or memory. Or some kind of issue where it can't boot. I just need to know if I want a knew motherboard or just try to fix the headsink incase my headsink is bad what do I do buy a new one? And yes the LED in back blinks rapidly no ticking sound and when I unplug everything it is a steady green then when I plug everything in with no ram(flashing rapidly)

Yes CCT I went through all of that I know its my mobo. I just need to know if headsink falling off would cause the psu. Or if I should just buy a new mobo. Because the thing is I found the clips to the headsink and know that that fell off but I don't know if I have other problems too.

If the northbridge burned out and shorted out then the psu may be damaged also. I have NO way of knowing. If you replace the mobo and the psu is bad then you may blow the new mobo. If the psu is replaced and the mobo is bad that may damage the psu.

Them's the facts, Jack!

You decide how much risk you want to take.

Haha Oh I know the psu isn't bad. I know 100% psu is working When I unplug everything. it is a solid light. I just wanted to know is my northbridge burned out would it cause the light to blink but I guess no one knows XDD just because if its a mobo and not just the nb. then I'd rather go for a new pc etc.

Yes, if the Northbridge overheats and shorts out, the power supply with go into a overcurrent/overvolatge shutdown noted by the flashing LED... In other words the motherboard is toast and it will have to be replaced

So thats it then if my northbridge headsink fell off its probably fried? (northbridge it self)
