Question about HP Pavilion A1050y (PU131AV) PC Desktop
I just had the same problem to deal with. My computer automatically turned on, and just when you thought it was gonna work, there was a single, loud beep. I immediately unplugged the computer. Make sure all the cords and chips are properly and securely connected. My problem was that my memory cards were loose. Maybe that'll help.

Test your PSU or replace it if your power supply units fan is not working your PSU is faulty
One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive
Test all leads that attach to your hard drive including electrical extensions,IDE,SATA
the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure connection and are not faulty or just replace them they could be faulty
make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error
even something as small as a faulty electrical extension or fan lead can cause you problems
computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly
motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail
check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working
also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in
check you CPU make sure its securely seated and has thermal grease
hope this helps
