Evo d310 memory problems?

I recently got a hp evo d310 and added 128 mb more RAM to go along with the 256 that was already in there, when i turned it on nothing appeared on the monitor and it beeped at me after doing so, i then removed the extra RAM and tryed to start it with only the RAM that it came with, but again the computer gave me one short beep followed by two long beeps, also with this the fans spin up then stop then sping up agian and stay on, and the key board blinks the num-lock light blinks on and off, i have already tried taking out the CMOS battery and clearing the CMOS, as well as adding new RAM just in case the original got fried, but no matter what i try it only beeps at me and nothing goes to the monitor. If anyone could help me out it would be greatly appreciated because i dont know if i fried the CPU, or what is wrong. Thank you

Depending on your boards type beep codes, one short, then 2 short beeps normally indicates a check sum error. This is when your board does'nt like the speed/size or make of your memory. Removing the battery probably hasn't cleared your cmos,look for JBAT1 terminal on your motherboard and place the jumper over pins 2-3 for a few seconds and then back to 1-2. Try to boot again with your original memory. With some boards you have to have equal amounts of memory in the slots (e.g 2 x 256mb or 2 x 128mb) and some memory may not be compatible with your board. If you get up and running go to this site to check memory upgrade options.

I had the 1 or 2 beeps , problem also when i installed memory.

I fixed it by taking out the memory and pushing it back in. It wasn't pushed in all the way. It has to make a click sound when you push it into position. After pushing it in all the way, into the slot, and it made a click sound, the levers on each side of it went down and clicked it into place.. then my computer started right up normally.

I had this problem and when reading through the solutions, I decided to unplug the power supply. In my case, one of the wires connecting to the power supply got chopped in two when the cover had been removed.... so check your wires also.

Well you can unplug your computer crack open the case unplug the power supply from the board and then plug it back up. turn it on and see what happens. If this doesn't clear it up unplug the hard drive and fire it up with it unplugged. turn it off and plug your drive back up and fire it up again. reboot it several times after each one of these tests. Take the memory out and fire it up a couple of times then replace the memory and fire it up again. Often times doing these simple procedures restores your settings and makes her work again.

Http:// For the Compaq Presario 5440 Maximum Memory: 384MB Standard Memory: 64MB removable Slots: 3 (3 banks of 1) USB Support: 1.x Compliant Q: What memory goes into my computer, and will a faster speed be backward-compatible? A: SDRAM memory with support for SDRAM, PC133 speeds. Because SDR memory is backward-compatible, you can safely upgrade your system with any of the guaranteed-compatible SDR speeds listed below. Q: How much memory can my computer handle? A: 384MB. Adding the maximum amount of memory will improve performance and help extend the useful life of your system as you run increasingly demanding software applications in the future. Q: Do I have to install matching pairs? A: No. No, you can install modules one at a time, and you can mix different densities of modules in your computer. But if your computer supports dual-channel memory configurations, you should install in identical pairs (preferably in kits) for optimal performance. Q: Does my computer support dual-channel memory? A: No. Your system does not support dual channel. Q: Does my computer support ECC memory? A: No. Your system does not support ECC. Because ECC and non-ECC modules should not be mixed within a system, install the same type of modules that are already in your system. Q: Will my system recognize the maximum upgrade? A: Possibly How much memory your Windows OS will recognize depends on which version of Windows you are running. 32-bit versions of Windows will see (and utilize) only 3GB or 3.5GB. To utilize more memory, install a 64-bit version of your OS. More information about OS memory maximums can be found at

I want my Laptop Dell Latitude C800 physical memory upgraded to 128 mb to 256 mb I myself already installed 256 mb Ram but it still showing 128 mb of memory...can I get help in this regard ?

I assume you installed another 128Mb of RAM to give you a total of 256Mb.
It is most likely the 2nd RAM module is not compatible with the other RAM module. Try using the same make.
Purchase and install a single RAM module 256Mb or 512Mb these are not expensive.

Upgrading memory on my Compaq Evo N400C notepad

What are the ram limits on a compaq presario 5000a. I put 256 ram in the compaq and it only reads 128. Why?

You can install up to 3 sticks of 512 mb of memory. Did you add a 256 stick to the already-existing 128? You need to put DDR266/PC2100 memory. To troubleshoot, remove the 128 stick and put your 256 in and see if it is recognized. You will know right away from the bios screen. Memory needs to be the same type.
