Question about HP Compaq dc7700 PC Desktop
Hi all, my desktop pc will not start up. There is power to the unit but when i push the start button the green light comes on then immediately goes off. All three fans in unit spin for a few seconds then stop The bottom light, red, then comes on and flashes and alarms with 2 beeps every 3 seconds. These beeps/flashes continue in lots of two 5 times then the beep stops but the light keeps flashing in the same sequence. I have removed the cover and blown the dust from the internals concentrating on the heatsync but still no joy.

This issue might happen due to RAM.
To resolve this issue:
Turn of the power supply for your desktop.
Please remove the side case on your tower(CPU).
find the RAM slot and remove the RAM from the Slot.
Clean the RAM terminals with the help of cloth or Eraser.
After cleaning place the RAM on RAM slot.
Now try to turn ON the PC desktop. If it is working thats fine or else you need to replace another RAM to check.
Please refer the below figure to find the RAM Slot and the lock to remove the RAM.
