There are a couple things you will need to check. Start with the basics. Remove the side and check all the power connections. Check the main board power connector but also don't forget to check the front panel power switch connection. Check the Case Open connector also if equipped and active.

If your still having problems check your RAM to make sure it's the correct type. It should be PC3200 DDR SDRAM DIMM. You may need to remove the new RAM and reinstall the old stuff just to help narrow down the problem. If the computer returns to normal operation after you switch back you'll know it a RAM issue. If not then something most likely happened while you were doing the swap.

Try switching the RAM back to the new again but use one at a time. If they all check out try using one stick and testing the RAM slots one by one.

After you have down this and everything checks out enter your bios and reset it to default setting and try again. After that if you still have no luck repost back here with your results and I'll try and help troubleshoot the problem.
Hope something here helps.

Did you put in the right type of RAM? many times this will happen if the wrong type is installed or if one of the sticks is bad, OR if it's too much ram for the motherboard to handle. The older systems that run with SDRAM will only go up to 512MB.

Motherboard replace processor cpu i have an hp pavilion a820n tower with no cpu or power supply can u tell me what kind i need?


the processor to fit the mobo is a pentium 4 socket 775. the original was a 3.2G according to the HP website.
most standard 500 watt power supplies should fit.
it does concern me why there is no processor or power supply in it though.
are you sure the mobo is ok? the only reason I would think these parts have been removed is because the mobo is dead and they've been transplanted into something else.

Green light on my power supply stays lit after unplugging


Usually the light will time out after the capacitor has drained. Your machine is getting a bit old , your PSU may be the problem. If you plug it in and push the on/off button and it blinks, fans spin and shuts down, it's most likely the PSU. Look for a in-line fuse on the Motherboard, if blown, replace. Look at the motherboard closely for damaged components, capacitors, etc.

I can not find the hard drive in hp pavilion A820n


Thank you for your Service!

The hard drive will be about 4"x5.5"x1" and is almost always mounted immediately below the dvd drives in an enclosure like the one you pictured. But you're in a situation where you don't have a lot of time to get it right, and if you're problem is that you're out of space on the primary drive, you probably need to be transferring to the new drive, and you'll need a working computer to do that. My suggestion is to take it to the repair people at one of the big box stores and have them get it going for you.

HP a820n No Power-up after City Power Failure


You have a bad power supply. It is not an expensive fix. Remember HP's take HP power supplies. When ordering either look on ebay for your model or order from part supplier.

Green power supply light blinking? HP Pavilion a820n


These wires vary based on the type of the board each wire lead is labeled to coorespond with the pins on the board. You need to reference the manual for your specific motherboard. If you don't have the original get it from the vendor support site or just google it. Unless your motherboard is an odd brand it should be easy to find.
