When the AC cord is plugged in, the Green light on the PSU stays on, does this mean the PSU is good? I tried disconnecting all peripherals, still would not power on, how can i tell for sure whether it's the PSU or mobo please?

Generally a solid light on the PSU means the unit is optimal. A blinking light means a fatal short.

 

Are you hearing anything running inside the case? Fans? Drives? Any beeping?

Is there a switch on the back of the PSU? If so, then you need to flip it. If not, then I would suggest opening the case and doing a visual inspection of all components.

 

Refer to this page : http://www.badcaps.net/pages.php?vid=5 for help on identifying bad caps on the motherboard.

 

 

Try removing all the memory sticks (RAM) and power on; then try one stick, then a different one, then two, etc. Until you get a beep or something.

 

Try unplugging the hard drive and power on.

 

If you're still not able to power on the system then install the hard drive on a second system and see if your data is OK. If it is then I would try replacing the PSU. If that doesn't work it is probably the motherboard.

I tried a lot of troubleshooting steps I had found on the net before posting here so now it's either the PSU or Mobo but I would need to purchase a PSU first and if it should turn out that's not the problem then that's money wasted.

PSUs are cheaper than mobos....

 

According to this page: http://h20000.www2.hp.com/bizsupport/TechSupport/Document.jsp?objectID=c01661171&lang=en&cc=us&taskId=130&contentType=SupportFAQ&prodSeriesId=3824206

 

You should be able to get by with a 350W PSU. Being that it's a slimline I'm PRETTY SURE you have a Micro ATX PSU. Check out this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817170015

I throw a lot of power supplies at those HP slimlines.  They are not Micro ATX either.

 

One warning, most of the replacement PSUs you get have straight SATA power plugs.  If you have the slimline with the expansion bay on the bottom, it will interfere with the plug and be about impossible to install.  Choices: Get a PSU with the right angle already there,get a 90 degree adapter, or leave the bay out if it is not being used.

 

Such a pain in the butt design.
