I think I've mixed them!

When I have 1 piece or higher of RAM in
  • CPU Fan keeps spinning
  • ON LED does not turn green
  • HD LED is full green
  • Ethernet Adapter has power
  • And the main problem, the monitor stays in standby (orange light)
  • NO BEEPS AT ALL!

When there is no RAM present in the computer
  • CPU Fan keeps spinning
  • ON LED is full green
  • HD LED does not turn green
  • 3 Short Beeps
  • Monitor remains in standby!
  • Ethernet Adapter has power

This has happened straight after I have *foolishly* inserted a RAM stick without first checking what type it was! After this, my computer went into this "standby" mode. I am quite qualified in Hardware, and I am a programmer, but this case is particularly new! I made sure to ground myself, with a grounding kit (belt and gloves), and I have already taken out all IDE connections to see if the status changed, which it didn't. I have tried a flea reset and have tried a BIOS reset, to no avail. I inserted the RAM carefully, making sure not to bump anything, and I have a proper Serge protector connected to my computer.

It is not the following things (I have checked up on these, tried these parts on different computers and tried different parts on my computer, to no avail):-
  • Video Card
  • PSU
  • Hard Drive(s)
  • Floppy Drive
  • CD Drive


If you got this far, thank-you, even if you don't know what is causing my dilamma! I'm glad you've read this far, and are interested in others problems!

Hi,

I have inseted RAM before without checking its type and all that happened was a BSOD.
Taking it back out solved the problem.
The three short beeps you hear are a sign of the lack of RAM.
Have you tried simply replacing it with the correct type?

Yes I have tried the original alone, I have tried probably 5 different RAM sticks in there, both SD and DDR.

Re: I think I've mixed them!

It's not physically possible to insert SDR into a DDR slot, DDR into an SDR slot, DDR2 into a DDR, SDR, RD etc...I think I've made my point. Each memory type is keyed in such a way that the locking arms wont close. What will happen though, is a small spark, some acrid smoke and a dead motherboard.

So, if you truly did use the wrong type; its because you're not trying to use sufficient force to attach RAM. You need not be so careful; turf out that anti-static nonsense and don't be scared to give this a shove and a knock. I've built, god I dunno, hundreds and Hundreds of perfectly functional PCs without one of those silly wrist bands; and dropped many a hardware component onto the floor without serious issue (hard disk excepted). I don't mean for you to treat the PC rough, but it's not made of fine bone china. This is a lesson most technicians learn eventually

I've even gone to great length to murder PC components before (both for fun and to ensure that an honest warranty claim was successful). The most fun I had was microwaving a DDR module for 10 seconds. It ran memtest for at least 48 hours without issue afterwards. ;D
