The number 1 slot is usually the one closest to the processor.

Make sure the ram is in the #1 slot on the motherboard, if not sure, keep trying till the computer can see the ram and starts up for you.

I just replaced the power supply to my hp a3500w and now it will turn on but all it does is beep. It doesnt recognize the moniter, keyboard or mouse. What else do I need to check? I tried disconnecting...

Hi kelden !

Usually when a computer fails to start, and all it does is making repetitive beeps, it means that something is wrong with the RAM memory.
Try to take off the RAM modules, clean the contacts, and put it back again firmly.

Best of luck,

I need to add memory module to my Dell desktop computer. I bought a 256MB Memory Module from Dell but it did not come with any instructions.

ok. which model ram you purchased. For installation of ram there is no instructions. Open cpu and put the ram in empty ram slot. Put in right direction because if you try to put in wrong direction it wont set because that small cutting in ram is help to set proper way. try it otherwise call any technician for help.

How do i put back together my windows xp honme edition compaq presario sr1420uk pc any help would be appreciated.i took all the parts out of my pc and dont know how to put it back together again

It's the reverse process you used to take it apart...the last part you took out is the first part you put back in and the first part you took out will be the last you put back.....If you can't get it back together, put it in a box and ship it to me. I fix problems like this all the time.....

I replaced the original two 250MB RAM with 4x1GB RAM and the backlight is now blinking but no power! It is an HP a820n pavilion desktop.

Did you put in the right type of RAM? many times this will happen if the wrong type is installed or if one of the sticks is bad, OR if it's too much ram for the motherboard to handle. The older systems that run with SDRAM will only go up to 512MB.

Just opened my laptop to clean the fan , when i put it back together again it powers up for 5 seconds then powers off again , please help.

Seems like your Ram or CPU Chip is either out or wasn't seated in its slot properly. You may want to open it back up and check for any mistakes.

I took a computer apart after it was beeeping and so i could check the mother board to make sure it was not burnt up and when i put it back togher now the montor and keyboard and mouse will not light up or...

So the beeping stopped?

Generally the beeping is coded with long and short beeps to tell you what is wrong. Often it signals a problem with the RAM but you need to look at the mother board manual to find out what it means.

It sounds like it does nothing at all now.

There are many easy mistakes you can make when putting a computer back together. It depends on how far you pulled it apart. Unless you are very observant when dismantling it you may have put a plug back on the wrong way around or something or missed a power cable somewhere.
You may have to take it to someone who knows where things go. It does not need to be a shop maybe you have a friend who knows about this stuff. Most of the common components in PC's all have the same rules about how they go together..

On the other hand it may have a broken component the beeps were telling you that after all.

I need to know if I put it back together right

If you pulled it apart and put it back together but now it won't work properly, try checking your IDE cables to the hard drive/cd-rom, make sure they aren't connected backwards. Otherwise just carefully look over the entire board, be sure that the processor, heat sink and fan assembly are all intact and connected properly, do the same with the RAM, power connection, any expansion cards.

HP Pavilion a800n wont boot up

it is possible you "Fried" the processor or something else. all it takes is a small static charge to kill those delicate circuits. dont wanna be all doom and gloom. i would strongly suggest you take this to a pro that can test all the hardware and find out. hopefully it's just a problem with your power supply. please let me know
