I have a HP Pavillion a1430n computer.

I upgraded the supplied 300w power supply and also purchased 2GB of GSkill memory from New Egg.

Was able to swap out the old parts for the new with relative ease, but when I turned on the power to my Computer, all I heard were the fans whirring at high speed in the case and a faint "beeeeep" sound repeating about once every 4-5 seconds. Nothing on my LCD monitor.

I opened the case to confirm that the CPU fan and case fans were indeed working, indicating that they were receiving power. The beeping appeared to be coming from somewhere in the motherboard.

Shut it down and tried again....same thing. To check, I unhooked the new PSU and reconnected the old PSU. Same and the strange beep, but no display. Took out the new memory and installed the old. Same situation.

So, new PSU and new memory, new PSU and old memory, old PSU and new memory and old PSU and old memory produce the same spinning, power lights on in front of case, a dull beeep every 5 seconds and nothing on my monitor.

Any suggestions as to what is happening. Here are the parts I purchased and installed:

The beeping sound is the motherboard saying something is not right. Often they have codes to let you know what the problem is - you would have to check the motherboard manual out to decode the beeps.

As you have tried every combination of memory and PSU, and all give the same results, I don't think any of these are the actual issue. The chances are that in the process of changing components something has come loose. Make sure that every cable in the system is securely connected, also make sure all the PCI/AGP/PCI-e/RAM etc. cards are also securely seated in their slots - best to remove each one by one and reinsert making sure that they are secure. Make sure you haven't missed a power connector to something - some motherboards have 2 power connectors! Also the hard drive, optical (CD/DVD) drives, floppy drive (if fitted) and possibly the graphics card should all be connected via a PSU power connector. Make sure all the fans have their wires securely connected to the right place - in particular the CPU fan should probably be connected to the motherboard.

Try all this and let us know how you get on.
