Remove the sticks and put them back again, make sure you hear the "click", the click means that the sticks are where they should be in possion,¨

Btw, you bought sticks that are suported by your Mobo i asume?

Installed 2 GB of Ram (both 3200 1 GB chips). PC would not boot coorectly with 2 GB installed (errors galore). However PC runs fine with only one 1GB installed. Running XP ?


Both ram sticks must be identical to work together. A different manufacturer of one can cause all kinds of problems. Did you go to 'setup' to make sure the machine recognized the second stick? The cure is likely to be purchasing another stick identical to the other new stick. Hope this helps!

I found some info on a forum, it says the 1 long and 2 short beeps is a problem with the graphics chip. You may need a replacement motherboard.

HP Pavilion a384x PC, 8 beeps, doesn't boot up


This beep code indicates a possible motherboard fault.
Some components may not be making proper electrical connection.
Open the desktop and remove the cable connectors and components one at a time and insert them on back on the motherboard.
Also remove the various PCI cards etc. and insert them back into the various slots.
If it still doesn't boot up or cannot go into the BIOS configuration, then it is a faulty motherboard. The hard drive should be OK but you won't know for sure until you test it by connect it to an USB hard drive adapter and plug it into a working computer's USB port.

Computer will not boot. was making some loud noise before it stopped working


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.

hmmm...that's not good. works fine with no battery. I suspect your motherboard may be taking a vacation from working soon.
