Hp pavilion 513n power up problem

When power is turned on it stays on for a few seconds and goes off. The cpu fan and case fan does the same. The power indicator on the front panel likewise. Help me trouble shoot this problem I suspect maybe the power supply, how can I test this unit?

I have an Hp pavilion slimline s3100n pc and after a while, it just shuts off with no warning whatsoever. When I try to turn it back on, it just shuts right back off. It's like I have to wait for it to...


Verify your fans are for the CPU and case are moving. You can remove the Pc cover and turn on the Pc. Watch the cooling fan on top of your CPU heat sink, it should begin spinning when you turn on your PC. If it doesn't then with the PC unplugged, make sure the connector for the fan is seated properly. From behind the PC you should be able to feel the Power Supply cooling fan moving air. Either of these could cause your PC to over heat and shut down.

My HP Pavilion turned off the other day and now won't stay on. It starts going through the boot up and then turns off before it gets to MS Welcome screen.


It could be overheating. If you are comfortable with opening up the case do this. Unplug the computer and place the it where you can work around it. Remove the knurled screw from the back of the left side panel. It's the one with the grill holes. Using canned compressed air blow the dust off of the cpu fan, back case fan, and the grill holes. Also blow out the power supply vent holes inside and the fan on the back. Hold the fans blades from spinning to prevent ruining the bearings. It could be a bad memery stick. Remove any cards and the memory sticks. Reinstall one stick, hookup the keyboard and display cable and power on the computer. If still nothing swap the ram sticks.

CPU fan turns for a few seconds and stops, pc will not turn on. Have tried a good PSU, same issue. Removed all connection to motherboard apart from 20 pin, 4 pin power + cpu fan and PW switch: same issue.


1. First of all Remove dust from your CPU fan and try again if issue has been not resolve

2. Second test your SMPS by the help of Green & Red wire. In case fan is turning properly it mines your SMPS is ok

3. Third & last kindly replace your SMPS For the same.

Hp pavilion 513n tries to start up then turns off


This is a case where something that is getting switched on during start-up is causing the power supply to fail... probably due to a short. How ever I believe the short is in the power supply

This is an older HP model ( I have a 530N) with teh same problem. I bought a new power supply and installed it.

My mom has a Pavilion 513n desktop. At boot up it


you're receiving a "No POST" issue. It could be any base component in your system. Strip it down to the bare basics. Power supply, motherboard, RAM, CPU, fans. HDD. Then start removing those components until you receive an error message. You'll be able to figure out which part needs replacing from that.

On my laptop the vent fan starts then stop and the power goes out


These machines have a terrible overheating problem! You will have to clean the fan opening and, put sylicon grease on the heat pipe and, heatsink that covers the cpu
