4GB ram installed but only 1 gb usable ???

Mmm now the Dell has DDR2 and I am just wondering too that it might be better to have 1x4GB stick instead of the two?

Now the chipset in the machine is suppsedly able to run 64bit http://www.intel.com/Assets/PDF/datasheet/316273.pdf the CPU https://ark.intel.com/products/31728...Hz-800-MHz-FSB also can support 64bit so I am guessing someone has installed a 32bit system on it as I find it hard to believe that the maker would have set it up with a 32bit system

Now do you have a sticker on the bottom of that machine with the OS on it? because it might be a 64bit on it and if you can still read the code then you could reinstall it with a 64bit system using a 64bit ISO.

As stated 3 GB is hardware reserved, to your graphics.

You posted the snip just fine.

Go Advanced is not an icon, it`s right next to "Post Quick Reply". With Post Quick Reply there`s no paperclip icon to attach a pic, so just use the Go Advanced from now on :)

Mate I think things have got a bit confused as I think the OP is referring to the refurbished Dell that I linked some stuff to we shall have to wait to hear from him which it is because that Dell unless I am terribly mistaken (or confused) only supports 4GB RAM and DDR2 at that

OK, then maybe this is it, and if so then you`re right at 4 GB max

According to the Dell article it is a Vista or XP machne and has a 2.0 GHz cpu, I wouldn't waste any time with it.

The OP will have to confirm the cpu. (Please do this for us)

From the Dell article

Intel® Core™
2 Duo processors 800 MHz Front Side Bus & 2MB Smart L2 Cache: T7250 (2.0GHz) and
Intel® Core™
2 Duo processors 800 MHz Front Side Bus & 4MB Smart L2 Cache T7500 (2.2GHz), T7700 (2.4GHz), T7800 (2.6GHz)


The best thing he could do is install a Samsung 850 Evo 120/250 GB SSD and Windows 7 Home Premium 32 bit, get rid of Ultimate, you don`t need it.

The COA will tell you which Operating System came installed on the PC.

And if the refurbisher installed Ultimate, they had better put a COA with an Ultimate Activation key on it.

Home Basic is probably the best edition for your computer.

It's your friendly simple Lay Back bear again.

1. As asked before; we need the exact specs of the computer to give proper guidance.

2. 3073mb of Hardware Reserve is way to high.
That is normally cause by a ram problem of some kind.

Example:
A. Wrong ram
B. Mismatched ram
3. Ram not installed correctly. Recommend using the methods of installing ram in the motherboard manual.
4. Possibly bad ram module slots on motherboard. This is seldom the problem but can be.

Note:
The system in my specs has Hardware Reserve of 61mb.

I presume you have things set as this picture from my computer. Is that correct?
