Installed RAM And Now Desktop Won't Turn On

*sigh* As many of you know, I'm dumb at computers. So please bear with me. Recently I went to crucial.com and let it scan my desktop and I ordered a RAM upgrade according to their recommendations. It showed I had 512 MB in one slot, and an empty slot that could hold 512 MB as well. So I ordered 512 MB.

The part number was "CT522914" and the description was "Upgrade for a HP - Compaq Pavilion 753n System 512 MB 184-PIN UNBUFF DIMM 64MX64 DDR PC2700 Pb-Free"

I turn off comp outlet, unplug the back stuff, ground myself and try to put it in as best I can. It's a little hard because there are some unmovable wires, so I have to slide the RAM in. I turned on computer. It did not show up when I pressed F# (I forgot which I pressed) nor when I checked Properties on My Comp. I tried a few more times, all unsuccessful.

My step dad tries while I'm away, he grounds himself, etc. And he removed the old RAM and tried to switch places. Now whenever we turned on comp it made a beeping noise, so I googled it and it said RAM wasn't in place well. So I myself fix it and it seems to be okay. But now computer doesn't turn on.

I switch things back to the exact same way they are before I installed new RAM, and it's still not turning on.

As far as I know, all the wires inside and on the back of the machine are exactly the way they were before I started, and the RAM is in the old setup at the beginning of this video.

This is a picture of the back of my comp, everything is plugged in but the ethernet cable (since I use it for my labtop):



Anyone have suggestions on how I get my Desktop to turn back on F4 irl.

Recheck all the wires and stuff and make sure the computer is plugged in. I've had a time where the problem was sitting right in front of my face and I couldn't figure out why the hardware wasn't working >.<.

When you say that the wires are immovable, did you actually try disconnecting them? I'm not going to go so far as to say disect your computer, but it helps if you have a clear view of what you're doing. It also lets you use the white clips that help secure the RAM in place.

It's very likely that your motherboard is unable to detect the RAM that you put in, or you did not put it in properly. Again, the white clips help. I think the beeping noise means that the POST test has failed, and RAM not being installed is one way to fail it. (I'm at a college computer that has no sound)

Maybe the hardware is faulty, as it is an old computer. Not likely though. Remedying for this should be a LAST resort!

Maybe Fiel could do a better job than I can, but these were the things that shot through my head.

try clearing CMOS

During the video, as you were installing the RAM, remember that satisfying click you heard when one of the RAM locks clicked into place? You should hear that click for both sides of the RAM. Do not turn on the computer until you hear both clicks. Failure to do so is bad, bad news.

The problem with RAM is that if it's not seated correctly, you could either fry the RAM terminals or fry the motherboard terminals which could cause your motherboard to not detect any RAM at all. Check the gold plating on the bottom of each RAM stick and see if there's any blackness or scarring that would happen due to high voltages. This is what happens due to bad RAM seating. The other option is much worse - the motherboard is fried and now the motherboard can't detect any RAM whatsoever. Given that you were unable to POST (power on self-test), it's definitely the detection of the new RAM that you added.

It looks like your Dad was able to get it to POST and got a beep code - that's a very good sign which means your motherboard is likely not fried. You have 2 memory sticks and two slots to put it in. That leaves 6 possible memory configurations:

RAM Slot 1	RAM Slot 2
Stick 1	Nothing
Nothing	Stick 1
Stick 2	Nothing
Nothing	Stick 2
Stick 1	Stick2
Stick 2	Stick 1

Try them all.

To continue with what X->L said, go here:

It's just moving around a jumper which is not too hard to do. Usually these jumpers are located at the bottom of the motherboard below and to the right of the PCI slots (or sometimes just directly under them)

Okay sec I will check all of this and record as I actually do it this time.

Edit: Er actually please expect an update Saturday night. I have to prepare for Chem Lab tomorrow morning. F4.

Edit 2: Alright sorry for the delay, I moved the RAM around kind of. After looking at the new RAM I ordered, two teeth on the bottom look messed up. So I took it out completely.

My old RAM stick is making the beeping noise, whether it's in slot one or two, and comp is still not turning on. Here is a video of the sound and what the new RAM looks like with the messed up gold teeth:

(Video is having a hard time for me. If it's not working then Go to this link please.)

Should I do the X->L thing? Or something else? Or is all hope lost?

RAM with blackened/scarred gold plating = good as dead. No mobo is ever going to detect it.

Might as well toss it.

As for the old RAM, I'd advise you to check the gold platings as well. Also, use a flashlight to look at the RAM seats to determine if there's any scarring there. If there is, might as well order a whole new computer. If there isn't, take it as a lesson learned and order new RAM from Crucial.

As far as the beeps, it's probably just angry with you about the RAM. Check your RAM, dude.

My old RAM stick gold thingies are fine, but I will let you know if the RAM memory thing is messed up. Honestly when I was turning it on the first day I installed it I smelled some like burning. Bad sign F4.
