Power Supply / Motherboard Problem

LambyCod · 10-28-2009, 07:06 AM

Hello everyone,

I am currently having a bit of a problem with my PSU / Motherboard. I was cleaning my computer today (inside of it) and put all the connections back in place but the computer will no longer start. (it could be possible i have put connectors in wrong spot? but not 100% sure really)

If I do the "paper-clip trick" with the PSU, it fires up fine and the fan goes, but if I connect the 24-pin connecter up to the motherboard (with nothing else conneted, it doesn't fire up.

Where should I start looking for the problem?
If you need any more info, please let me know

Thanks guys,

Nick

Can we get the motherboard specs?

Also, the make and model of the motherboard

Check carefully the front panel header to make sure you have the pwr sw lead in the right place. If you look on most motherboards (may take a small magnifying glass), the place for each wire(s) are printed right beside the header.

BTW, don't double post your question after you have posted the issue.

Tumbleweed36: Is that the switch that is the power button on the front of the computer?

Sorry about the double post, I wasn't sure what section was the best to post it in, so I posted it in both.

Yes that's to the power button.
I saw you stated the 24 pin did you also have the 4pin cpu power plugged in?

Hi,

I had the 24-pin connected as well as a 4pin one that is coming from the PSU, do I need to hook up all the little cables coming from the power button (Power, Reset, LEDS etc..) just to get the PSU started?

UPDATE

Okay I managed to get it all connected up, it turns on now. HOWEVER, if I turn it on with the case vertical, it cuts out after about 15 seconds the first time and then 5-10 seconds the second time.

As soon as I place it horizontal it starts up fine.

What could be causing this?

**greenbrucelee** · 10-29-2009, 12:49 AM

could be the connection is coming loose because it's not clipped in properly.

LambyCod · 10-29-2009, 01:13 AM

I checked that and didn't seem to make a differnece.

I started it up horizontal and got into the BIOS and went to monitor the CPU/System Temps, as soon I sat the case up vertical the CPU/System temperatures sky rocketed, before the CPU was hovering around 60-70 celcius but when I put case vertical it continued to go up until it got to 200 degrees celcius when it cut out.

What do you guys think?

Check the CPU heatsink is secure to the CPU.
What motherboard / CPU do you have?

LambyCod · 10-29-2009, 03:11 AM

Hey wrench97,

I am not totally sure, it is a reasonably old MSI motherboard but as for the CPU I am not 100% sure, I checked the heatsink it was secure but I noticed all the thermal paste was gone (I forgot to put more on)

So I will order some more and when it arrives try that I think?

**greenbrucelee** · 10-29-2009, 03:26 AM

you will have to clean the cpu and heatsink of the old paste and apply new paste.

when the heatsink is removed from the cpu the old paste is basically useless and if no new paste is applied overheating issues will occurr.

LambyCod · 10-29-2009, 04:47 AM

Okay, thanks greenbrucelee.
The computer is overheating even when vertical now, so pretty sure its the heatsink/cpu.

I found a deal with a local store heatsink + paste so getting a cheap deal (Only $20) for a pretty good heatsink.

I'll let ya know how it goes, might not arrive till around Mon-Tues next week though.

**greenbrucelee** · 10-29-2009, 04:50 AM

you don't really need another heatsink unless your going to overclock then a good one is needed, just some decent paste like artic silver 5 will do.

LambyCod · 10-29-2009, 05:19 AM

Arctic Silver Ceramique (2.5g) is the paste I bought, this will still be okay wont it?

**greenbrucelee** · 10-29-2009, 06:00 AM

should be ok yes.

LambyCod · 10-29-2009, 03:35 PM

Okay, thanks. Will let ya know how it all does.
