RAM wont install.

Specs: Windows XP.
I was taking out a fan because it was very loud and one of my 512mb of ddr RAM popped out. SO when i tried to put it back in 1 side goes down all the way but the other doesnt so its sticking out. After all this when i turn my computer on nothing comes up on the screen?

Are you sure you've got the right orientation? The stick will only fit in one way. If it's backwards the notch between the gold contacts won't line up with the (what's the word I'm looking for) bump (?) in the bottom of the ram slot..

If that's OK make sure neither the stick or slot are damaged.

Then try again. With the release tabs in the 'out' position, line up the stick gently in the slot until you meet resistance. The push hard on one side of the stick until it click into place and the release tab is in the closed position. Then do the same on the other side of the stick.

Now that's what I call a sticky situation

Then when i push on the other side it wont go in any further until its at like the bottom notch not the top.

Then as DAVE said, you may have turned the RAM 180 degrees. I hope you have the computer unplugged while messing with the RAM. Especially if you are installing it backward.

If you installed the ram module backwards and then booted the computer, the ram module you installed backwards, and the ram slot you had the backwards module in, were both fried instantly, and neither will ever work again.
You would probably have noticed a strong smell of burnt plastic, if your sense of smell is okay.

If you examine the ram module that was backwards, you will see that one or more contacts have been damaged and may even be missing - has / have been vaporized.
If you examine the ram slot the backwards module was in with good lighting, you may need something to magnify what you're seeing, you will see some contacts in the slot are similarly damaged or missing, and evidence that the plastic has melted in some places.
You may see black carbon deposits on either or both of the module and the ram slot.

Throw the damaged module away.
If you clean up the damaged ram slot so that it has no carbon deposits, and no melted plastic bridging the contacts in the slot, and no melted contacts touching the next one, your mboard MAY still work if you install a good ram module in another ram slot - if not, the mboard must be replaced.

( How do I know these details ? I installed a ram module backwards once, and only once, without making sure both latches latched easily, when a data cable was in the way of me seeing the whole slot. The mboard would not boot after the event, but after I cleaned up the ram slot the mboard still worked. )

Clean up the damaged ram slot.
If the computer will boot with the one good 512mb module in a good ram slot, then you MAY be able to install a larger capacity module in that slot, if that's the only other ram slot you have.

The notch on the bottom of the module must line up with the bump in the ram slot, otherwise the module is backwards and you can't get both latches at the ends of the ram slot to latch into the ends of the module, at least you can't without using a lot of force and bending the mboard, and the ram module can't go all the way down in it's slot.

We need the make model of your brand name computer , or the make and model of the mboard if this is a generic desktop computer, in order for us to be able to tell you how large a ram module you can install.
The specific model of a brand name system is shown on a label on the outside of the case somewhere, or it can often be determined by going to the brand name's web site.
For Dell computers, they have a Service Tag number - the specific model can be determined by using that on their site, or can often be determined there automatically by you downloading some software. The Service Tag number should be on a label on the outside of the case, probably on the bottom on a laptop, on the back on a desktop, and is often also shown in the bios Setup.
The model, sometimes the make, of a mboard in a generic desktop system is usually printed on the mboard's surface in obvious larger characters, often between the slots.

Otherwise, XP will work okay with 512mb of ram for most things.

Throw away the damaged module ! It's useless !
You can clean up loose carbon deposits with anything - hard carbon deposits you would have to scrape off. Use whatever you have - a small knife, small flat tip screwdriver, a nail, a small file, whatever, to pry away of file away melted plastic from touching contacts, or sever the plastic or connection between contacts, etc., etc.
If you don't have anything small enough, get something suitable, e.g. from a local "dollar" store.

NOTE ! You may have another problem !

Look at the label on the power supply. If that says it has a 250 watt capacity.....
Remove the Radeon x1600 or x1650 (AGP I assume) video card ! Connect your monitor to the onboard video port.

If your model has a 250 watt (output) capacity power supply, the same as the m1000 (see below), using that card will fry the power supply eventually !
The computer may not boot in any case if you have a 250 watt PS and have that card installed, or if it does, it won't eventually !

The Radeon x1600 or x1650 video chipset requires that your system has a 350 watt or greater PS capacity !
You could probably get away with a 300 watt PS, but a 250 watt one is not enough .

Your power supply must have at least the minimum capacity required to support a system with the graphics card you are using installed, or the max graphics card you might install in the future.
(Onboard video - video built into the mboard - IS NOT A CARD ! )
If that info is not in the ad for the video card, you can go to the video card maker's web site and look up the specs for the model - often under system requirements - the minimum PS wattage, and, more important, the minimum amperage the PS must supply at 12v is stated. If you don't find that, any card with the same video chipset including any letters after the model number has very similar minimum PS requirements. Some power supplies have two or more +12v ratings - in that case, add those ratings to determine the total +12v current capacity.

If you're a gamer...
In most if not all cases, the max capacity rating of the PS is an intermittent rating. It's recommended that you do not load your PS to any more that 80% of that rating if you are going to be using something that puts a constant load on it, such as playing a recent game for hours on end. In that case, you multiply the min capacity stated for the system with the particular video chipset on the card by 1.25 to find the min. capacity of the PS you should get.

If you need to get a PS with more capacity, you can usually replace it with any decent standard sized standard ATX PS.

If you want to be able to install any possible video card, a minimum 600 ot 650 watt power supply will handle any current high end video card.

Standard (PS/2) power supply size - 86mm high, 150mm wide, 140mm deep, or 3 3/8" h x 5 7/8" w x 5 1/2" d , or very close to that, though the depth can be more or less for some PSs.

Don't buy an el-cheapo PS.

Are you in the UK or the US, or where ?

Have you gotten the mboard to boot yet ?

Is your mboard the same as the one for the m1000 ?

What's the HP System number on the HP label on the outside of your computer case ?

The computer will often still work when the PS capacity is less than the minimum recommended to support the video chipset, but in your case there is too much difference between 230 and 350 watts, and it's loaded to 100% of it's capacity all the time or most of the time the computer is running , especially when you're doing something that definitely puts more load on the system such as playing a recent or fairly recent game high end game, and eventually the PS is damaged and WILL malfunction. When a PS malfunctions, or especially when it fails completely, it can damage anything connected to the computer, most often the mboard - the computer may not boot even after you have replaced the PS.
It's best to replace an inadequate capacity PS BEFORE you have major problems.

"Im in Canada."

So am I, in Alberta.
Most people who post on this site in the US, UK, Canada, Australia, or New Zealand, probably in that order.

"how do i tell if the mboard has booted?"

Remove the x1600 or X1650 card, connect your monitor to the onboard video port, if you haven't already done so, to eliminate the possibilty the PS no longer has enough "poop" to boot the computer with that card installed - in that case, it should boot if that isn't present.
I'm assuming your mboard has onboard video because the one for the m1000 model does.

If you have cleaned up the damaged ram slot thoroughly, and have installed the undamaged 512mb module in the other ram slot properly, if the mboard will not boot, the mboard's probably fried.

If you're not sure which 512mb module is damaged, compare the two of them side by side, on each side of the module - it will be obvious which one is not right.

The only other things you could try are these -

Make sure you have a speaker or speakers or the equivalent connected to the mboard so you can hear mboard beeps (see your mboard manual if you need to). (If you haven't messed with that wiring, you heard beeps previously, it's already connected.)
Remove the AC power to the case/power supply.
Remove all the ram.
Restore AC power.
Try to boot.
If nothing else is wrong, you will get no video but you will hear a pattern of beeps that indicate no ram is installed, or a ram problem.
E.g. for an Award bios or a bios based on one, that's often a beep of about a half second, silence for a half second, a beep of about a half second, silence for a half second, continuously.

If you hear no beeps, the mboard is probably fried.

If you DO hear beeps, then both ram modules were damaged.
You could try installing a different know good DDR ram module.

There is a definite possibilty your PS is fried, not because you installed the ram module backwards, but because it's inadequate when the x1600 or x1650 card is installed and has been damaged.

Try connecting a working PS from another computer you have, or a friend has. It doesn't have to be in the case - prop it up beside the case so you can connect the wiring.
If the Radeon card is not installed one that has a 250 watt capacity will do.
If the Radeon card IS installed it should have a capacity of at least 300 watts, or more; if it's 300, don't run the computer for a long time with it connected.

Did you get the mboard to work ?

" ....becasue the ps was too low would that lead to fps lag and lower fps" ?

If you mean in something such as games, higher end games often place the greatest load on the system and if the PS can't supply enough current @12v that could certainly produce those problems.

By the way, many 'hits" on the web recommend a minimum 400 watt PS when you have a Radeon x1600 or x1650.

A minimum 512mb of ram with XP, 1gb or more recommended for a Radeon x!600 or x1650.

Many higher end games have a higher minimum recommended amount of ram, often more than 1gb.

Things that slow down Windows would also slow the max frame rate.
