So I found 2 memory cards I had on my old computer and decided to instal them on my new computer
I opend it and tried but seems they don't fit
I removed the already instaled memory(im not even sure it's the memory) and then put it back again
But now ehen ever I start the computer it does nothing here's what happens:
1-the screen stops showing anything like there is no computer attached.
2-the light lights and never stop(the one that tells us when the computer is processing something).
3-no respons at all the cd driver doesn't open the num luck doesn't light NOTHING.
Please try to tell me what to do :confused:
Oh and I can't lose my E driver because I have my back up there:(
Thanks a lot

Lexmol,

First rule of do it yourself creed is "If you don't know what you are doing, ASK!" :)

RAM is not a universal size. That's why it is not always swappable. Also the speed of the memory changes between models and different speeds do not play well together.

Please replace the boards you took out. One may contain the PC CPU or ROM BIOS.

Without the ROM (Read only memory) BIOS (Basic Input Output System) your PC will be a vegetable.

Suggest you start back at your original hardware set up.

First check your power supply. If it has a red switch to change voltage, make sure it is on the correct setting for your country.

Before opening the computer case have some Electrostatic Protection. Either a wrist strap or a mat. And they must be connected to a ESP bonding point. This is a special plug (UK) that goes in to an electrical socket or earth connection. You can buy this at Maplin or any other computer hardware peripherals store.

Check the power cable to your cd drive is connected.
With the original memory take it out and re-seat it. Memory modules only go in one way round. Then turn the computer on.

If your cd drive drawer does not open. Disconnect everything from the psu (computers power supply) but keep the cd power cable connected and turn on. If the cd drawer opens continue below. If it does not open connect only the hard drive and listen to see if it spins up. If it does your cd drive has failed. If it does not you have a faulty power supply. Replace the psu and proceed but note when a psu fails it usually kills something else at point of failure.

If it still fails to run/boot:
Remove all extra cards from motherboard like graphics card. And try boot.

If the boot sequence gets further after this then one of the removed cards is at fault.
Replace them one at a time booting the computer each time to see which one causes the fail. Then replace the failed card.

If the boot sequence never got further when all cards were removed. Either the motherboard, cpu or memory modules are at fault.

If you want to proceed to fix this I would replace the cheapest part first. Usually the memory modules. Remember static electricity can damage all these parts so use electrostatic protection.

Usually when it comes to motherboard or cpu failure it is more economical to buy a new computer. But if you want to continue, replace one at a time - cpu then motherboard.

:) I know I will never open a computer again :)
But you see I didn't put any of the new memorys they didn't fit and I didn't take out the memory that already existed I removed it and then put it back again so it's the same
But maybe just maybe its not fully instald although I put it more than once ill probaply take it to someone who under stants it :)
Thanks again

Lexmo,

You may have killed the system dead. Did you were a ground strap connected to the frame of the PC when handling the cards?

You can release a static electric charge from your hands into the cards just by touching them. That static electric charge has been known to fry chips.

:O
I didn't wear anything on my hands but comon can that kill the chips?!
Holly...
Ill sell my memorys to fix the computer :)

First of all, you need to know what exactly you removed. "Memory" is not the proper name of any computer part, I assume you are talking about RAM. As said above this is not universal (your RAM chip may not work in another computer). If you intend to do this yourself, check and make sure you installed the RAM back exactly where it went before and it's in correctly (it only fits one way) and also that it is in there tightly, it should click when it's all the way in.

If that doesn't work, maybe you removed something else and not the RAM. The best idea is to take this to a computer shop and have them look at it.
