Read the FAQs and did some research on the site.
Here's my deal HP s3120n (slim line, small case home computer) never inside till today. athlon 64x2 4200+ processor, 2gb, 320gb hd motherboard onboard graphics http://www.hp.com/hpinfo/newsroom/pr...ine_s3120n.pdf 2 days ago it was sluggish to start. Turned on, got to starting up, then blank screen for 2 or 3 minutes, then eventually started. yesterday, wouldn't start. turned on and off multiple times, no start. no power to keyboard, monitor in sleep. no significant hard drive activity. Today, opened her up, 1 year old, about 14 mo so out of warranty. very clean inside, no significant dust or anything like that. Pulled ram out, cleaned, replaced. Turn on computer, blue light up top lights, fan runs on cpu, the usb ports have power. hard drive starts to spin, but doesn't seem to cycle at all. I get no power to keyboard, nothing happens when i hit it, etc. disconnected hard drive, and dvd, start up, same thing, fan spins on the cpu, nothing to keyboard, etc. capacitors look fine. |

Sounds like a blown PSU, yeah, even if things power on, knackered ones do that.

Just swap it out mate, the symptoms you describe suggest PSU and being the cheapest part it's the first thing to do anyway.
I wouldn't power it on anymore, don't want to take the motherboard down too if the PSU is dodgy. |

I believe this model was manufactured with a 160W PSU, which is very likely underpowered.

Also, as this is a slimline model, I dont think a standard "off the shelf" PSU will fit in the case. Check out the dimensions and also have a good look at the motherboard connector, as some of the HPs have non standard connectors. You may find your only option is to get hold of a genuine HP unit. Someone reported thet this unit will fit, but dont take my word for it, check it out thoroughly, before parting with any cash. My System: Home Build

going to try a power supply then. i took my old computer apart to see if i could check it but it has a different plug for the mother board, 20 pin, versus the 24 pin on my new one.
The one at issue seems to only have a 24 pin connector to the mother board and 2 controllers 1 for hard drive and 1 for dvd drive. I assume most power supplies will have at least this as long as I buy a 24 or 20+4 pin controller right? thanks for the help, i'll report back when i get it and get it installed. I'm going to try to go with a higher power unit, as the stock one is 150w. Are there any brands to preferentially buy or to avoid. thanks Joe Joe |

Searching around found this website to check the power supply.
Now i couldn't start my computer, only turn it on, fan on cpu runs, hard drive spins, ligths come on, but that's it. No cycling of the hard drive, etc. So probably not a real test, as it's very little load. http://www.driverheaven.net/guides/testingPSU/ anyway it runs 3.3, 5, and 12 volts as it should. As i understand could still be the power supply right? or is it more likely something else like motherboard or cpu? thanks Joe |

If the PC didn't/wont power up, then the test is a bit meaningless really ..... it only helps if you can run the test at full load, as this is when "iffy" PSUs will break down.

Regarding the new PSU .... check the physical dimensions and fixings with your existing unit, as being a slimline case (as mentioned earlier), it's likely that a standard unit will be to big or you will end up having to cut your case/drill new fixing holes to get it to fit.
If the mobo connector is not standard, you may be able to source an adaptor, by searching on ebay. |
