Take all the memory out, start up, hear the beeps.

Put the new memory back in, make sure its the right way and well in place, try staring up again.

I have a Acer Verton E430 Desktop. Suddenly upon restart after the initial beep and Acer splash screen returns to restart with one short beep and process continues on and on.. Advise how to solve.

One short beep can be DRAM refresh failure.
  1. Remove RAM memory, Graphics card, other Plug-in cards, and Drive cables from your mainboard.
    Only CPU + Fan + Power cable are installed on the mainboard.
  2. Power on the PC, and listen to the beeps:
    • no beeps => Power supply, CPU, mainboard or BIOS is most likely defective.
    • some beeps => remember the beeps and next step.
  3. Power off the PC, and insert the RAM memory.
  4. Power on the PC, and listen to the beeps:
    • no beeps => RAM incorrectly installed.
    • same beeps as before => RAM is most likely defective.
    • beeps have changed => next step.
  5. Power off the PC, and insert the Graphics card.
  6. Power on the PC:
    • some beeps => Graphics card is most likely defective.
    • blank screen =>Graphics card is most likely defective.

Installing new motherboard, processor, mem, and video adapter. Powers on but no post.

If the beep is a very high pitched tone, turn off the computer. Your CPU is overheating. The thermal paste may not be spread correctly on the CPU or the heat sink isn't properly installed.

Otherwise, it's probably a memory error. This machine takes 2 GB of memory as 2 single GB memory sticks. Try booting the machine with only one DIMM installed. Try each stick individually before getting replacement memory.

I hope this helps.

Hmm well the post beeps tell me it is memory issue. Actually it tell me it is a video memory issue but since most laptops use the main ram for video I am thinking memory. Since it is used and probably shipped to you I would just try reseating that. Looks like you did and the fact that you are loosing the time and date tell me the CMOS battery might be going bad of just disloged. Normally this battery is under the ram module. Try taking that out and putting it back in. If that does not work I would take it to a place that can install a new memory module for you and test it.
I do not think that is was any software you installed.
Hope this helps.

Unsuccessful memory upgrade

I work on GX 620 dells alot. I work on them for a school district.

They have alot of issues. Particularly with memory issues, try reseating the memory or trying a different memory slot. You shouldnt have to under clock it. Just run it as normal.

If it beeps on start up, then its probably a memory problem. The dell website has online support and will give you a list of dell beep codes

you can type in your dell service tag number located on the back, or just picking out the model.

Try using just using the new memory stick by itself without the old ones.

If your computer came with a disk ( it should) It either Blue or Black, if its black, boot from cd and it will load a test program, try using that to check that the memory is good. If its blue then its older and just lets you re-install windows.

If its looping, where it gives you a black screen with options to boot in safe mode but restarts no matter what option you pick.

Load the windows cd like your going to re-install, Boot from cd ( F12 ) on boot, pick boot cd drive and when it loads, pick ( R) for repair and when it goes to command prompt, type in. ( chkdsk C: /p ) exactly like that

it will run a repair. When done, type EXIT and hit enter.

When it restarts, remove the disk and see if it gives you the option again to pick how to start windows.

Pick ( star windows normally ) see if this works.

If the repair works then it wasnt the memory as much as it was just Dells Crappy hardware configuration.

Let me know what happens and i can try to help you further.

It could be a bad memory stick that you happened to get.

Good luck.

Hello kabousven,

Could you be more specific with the screen of death? Can you read any specific errors?

Also will you list all of the other hardware installed? Screen of death during XP installation can mean that certain drivers are required,but not there.

Also, what is the model and make of your motherboard, and when you plug in your video card to the other slot, how many beeps do you hear? 2,3, fast or slow?
