Hi there.
I'm rebuilding an HP Pavilion system where the CPU/APU had gotten a bent pin. I just received a new APU from NewEgg, an AMD A4-3300 FM1-socket APU, and I'm fairly certain it's working. The computer had been taken apart after the bent pin, but I recently decided to recommission it. I don't remember the model number of the Pavilion system and the label has been worn off the front panel.
First, here's the specifications of the build:
I tested with an external video card (AMD Radeon HD 5450 I had lying around), using the VGA port, and also a different monitor, to make sure it wasn't a display problem, but there is still no picture on either monitors. Both monitors work on my netbook.
I think I correctly reset the BIOS settings. I first used the CMOS jumper settings, as per http://h10025.www1.hp.com/ewfrf/wc/document?cc=us&lc=en&docname=c02966470 (under "Clearing the CMOS settings") then followed another method of removing the RAM, removing the CMOS battery and waiting 10 minutes, and plugging it all back in. The system still does no POST, but unless I'm missing something, the BIOS would seem to be reset, and that is hopefully not the issue.
I tried taking the motherboard and the power supply out of the case, lying it on a wooden desk, and hooking it up. I turned it on by shorting the power on front panel pins with a flat head screwdriver, and the same issues came up. No POST, no video.
I then tried to switch around the RAM slots used. The HP boards diagram at the link above labels the two slots as XMM1 and XMM2. XMM1 slot exhibits the no POST no video issue. When I plugged the RAM into the XMM2 slot, I got 5 beeps, followed by a pause, 5 times, accompanied by a yellow/orange blinking power button light following the pattern of the beeps. Googling this pattern returns results suggesting its a memory error.
I removed the memory again, cleaning all dust from its contacts; it was a little dusty and a single hair had become lodged in one spot. After cleaning, I still had no luck. Perhaps someone could suggest a method for cleaning out the RAM slots themselves? Would carefully hovering a low-power vacuum hose over the slot, making no contact with it, to suck up any dirt work, or would that damage it?
The other confusing part is, is the memory error due to the RAM not being in the XMM1, or would it work in XMM2 but the memory module itself is bad?
I don't have another desktop computer to be able to test the RAM module, and I doubt I'll be able to any time soon. All my friends have laptops, but perhaps I'll have to take the plunge and have a computer shop test the memory.
One other thing to note is that when the RAM is in XMM1 slot, it is a tiny bit loose on the bottom and can be wiggled about ever so slightly. Not sure if perhaps this is a possible culprit for the slot not working.
After countless hours of Googling and testing things, I've hit a bit of a wall. I'd be highly appreciative of any help that could be provided.
Thank you for your time,

First, here's the specifications of the build:
- HP AAHD2-HY (Holly) motherboard
- 1 x Kingston KVR1333D3N9/4G 4gb memory module
- HP 300w power supply (model number: D10-300N1A)
- AMD A4-3300 APU (2.5ghz) with AMD Radeon HD 6410D graphics
- no CD ROM, no hard drive
