Question about HP Pavilion a1220n (A1220NED904AA) PC Desktop
I had installed two 1 GB memory sticks in my tower along with the installed 512 MB memory sticks. When I try to turn on the tower, the front panel light won't light up. In the back of my tower, a green light flashes slow in the back part. Do that mean that I need to replace the power supply?
Try removing the 512 MB memory to see if it does work with the 1GB stick only.
It's not the power supply that does have a problem. It has something with your memory stick.

That is a power failure, please try change the power supply..or test the voltage in the wall outlet if it rate 220 volts if not then power supply is the main causes. Sometimes the software's got conflict due to virus infections.
try to scan your computer with a potent antivirus maybe it help.

SOURCE: Memory upgrade didn't work
sound like either the memory is incorrect or u may need to load the default settings in the BIOS
enter the BIOS / setup screen for the motherboard and see if the system shows the 2 gig installed
see the adding memory guide below and it will explain everything

HP Support > Pavilion a1600n desktop computer > Motherboard Specifications,
Scroll down the page to the illustration, and photo of the Pavilion a1600n motherboard.
On the motherboard illustration where it states DDR2 XMM1 (64 bit ,240-pin module), and DDR2 XMM2 (64 bit ,240-pin module), is where the two 1GB ram memory modules go.
On the motherboard photo, it is the two Blue in color ram memory slots.
The 512MB ram memory modules go into the Black ram memory slots.
[DDR2 XMM3, and DDR2 XMM4]
The Blue ram memory slots are one Channel. (Channel 1)
The Black ram memory slots are the second Channel.
You want to keep LIKE ram memory modules in the same Channel.
If you are having problems with the PNY ram memory modules, tell me what the manufacturer code is on them.
(Or if you bought them off of a website, see if you can copy and paste the link in a Comment. Believe upper right of your page.
FixYa is constantly undergoing changes to improve the website, is why I indicate that)
You need low density, unbuffered ram memory, DDR2 Sdram ram memory.
[DDR2 at either 533MegaHertz, or you can also use DDR2 at 667MHz.
PC2-4200 and PC2-5300 respectively ]
Don't try out any high performance ram memory is my recommendation, because the Voltage required by the ram memory, may not meet the factory default voltages that are preset in your computer.
[Factory Voltage default setting for ram memory for your motherboard, is set at 1.8 Volts.
Some high performance DDR2 ram memory requires 2.0 Volts, 2.1 Volts, or even higher ]
