after i install new ram which seems compatible, the computer just beeps and no display

Solution
The Acer computer supports DDR3 memory only. DDR2 memory will not fit nor work with the computer.

Where did the memory from? Do you have a web link to the memory?

We need more details of the memory before we can confirm compatibility. Memory part number is preferred, if there is one on a label. And the memory part number does not start with DDR3 or DDR2. The part number might start with a C, or a K, or an H, or an F, or a T, or maybe some other letter, or maybe a number.
Sorry, but that is not the make and part number.

Usually there is a label with the manufacturers name on it as well as the module part number.

If you're having difficulty finding this information, is there an online site which has a photo and details of the modules?

Alternatively, if there is a label on the modules, can you copy all of label text and post the text details here?

Or if you have a digital camera, can you take clear photos of the modules label and maybe a clear photo of the modules memory chip as well (if not hidden under a heatspreader).

This required information is important in determining whether the modules are actually compatible or not.
 
Thanks for marking the topic as solved, but the issue is not really solved yet(?)

Do you manage to sort out the problem? If so, what was done?

If not sorted out yet, then please provide details of the memory modules. The modules may not be compatible with the system and/or with each other.
