If you want to get more detailed specs, Speccy is a good program to use to show you exactly what's in your computer.

EDIT: Just noticed that you said no internet on the machine. You can go into Device Manager to get a slightly better idea of what is in your machine.

You wont be able to use more than 3gb ram with that 32 bit os. You will need a 64 bit OS.

The Q6600 uses DDR2.

I've never heard of DDM.

Additionally, yes, you'll need to upgrade to a 64bit OS to use more than 3.5GB.

If you want to upgrade your RAM, the best way to check the DDR type is to remove your current RAM and check the labels on it. It's likely DDR2 or DDR3 depending on how old the computer is.

Look up a video on how to install and remove the RAM. Try to remember which slots the RAM sticks were in before you remove it too. Depending on your motherboard, it might matter.

If you don't want to open your computer just yet, you can also download a program called CPU-Z and check this page for the information you're looking for:

Buy RAM sticks that are the same DDR level as you currently have, and have about the same frequency. If you use CPU-Z to figure out the frequency, you have to multiply the frequency by two to get the real frequency (533Mhz * 2 = 1066Mhz). So in the above case, you'd want to buy DDR3 RAM with a frequency of ~1066Mhz.

Ok, thanks for the comments so quickly.
So what I'm getting here is I need to upgrade to 64-bit. Maybe because I'm stupid but now I have more questions.

Is it possible to upgrade to 64-bit without having to buy a new PC?
How would I do this?
What would I need to buy?

Thanks again anyone.

You would need to buy a 64bit version of Windows. You can install it on your current PC. As with any install of an OS, you'll lose any data on the drive you install Windows on.

Interesting.
Would this include programs, and important stuff the computer needs to actually run?

EDIT; Had another question.
Where would I be able to buy a Windows 7 Home Premium/Professional OS install disc from?

Windows comes with everything that is needed for the computer to run. You'll be left with a bare-bones system and have to start from scratch. This means re-downloading all the programs you once had. If you have any important documents (perhaps stuff from school you need) store them on Dropbox or something before you proceed with the install.

You should be able to buy Windows from any online retail store that sells computer stuff (Newegg, Amazon, PCOutlet has it 13 dollars off right now if I recall correctly). Alternatively, Best Buy should still be selling copies. I'd recommend Windows 7, but you could go with Windows 8 if you'd like. Windows 10 will come as a free upgrade when it comes out to current owners of either Windows 7 or 8, so buying Windows Vista again at 64 bit would be less than ideal.

Alright, thanks that calms a lot of nerves.
Two new questions now.

1. What do I buy, a Installation disc or a product key? (I don't know the difference)
2. Is £20-30+ a good price for an installation disc or product key?
3. (Not a question but a statement, I think.) I've looked a little around eBay and I found a legit looking installation disc for around £30. I need to know if this is actually legit and if the price is good or not.

Thanks again

EDIT: If anyone could find/know a good page where someone/some retailer is selling Windows 7 (Online or not) that'll be great. (Professional is the best one I think. I bet that is just up to personal opinion)

1. If you buy an installation disc, you get the product key as well, but if you buy a product key, you'll need to get the system .iso disc file from Microsoft and install using this
2. Not sure.
3. I don't think people are selling fake discs, I know people are selling cracked Windows as legit one though

The disc (or flash drive if you go this route) itself is necessary for the installation. It contains the files required for the actual installation of Windows. The product key is usually printed on the box itself. You have to manually enter it during the installation of Windows.

If you had an installation disc, you could buy a product key. However, I wouldn't trust purchasing a product key off eBay. The product key is checked once you get an internet connection on your machine. If its invalid or already taken, you're going to run into more problems.

I'm not too experienced with doing things this way so I'll refrain from any more comment on that subject.

Ok, I know what I need to do now.
I just need to find a installation disc that I know I can use and is cheap so, if anyone wants to help.
Thenks :3

DDM afaik isn't anything unique, it's just a strange way of saying RAM and it might be a format to the ram specifically.

Professional is all you'll ever need, since ultimate is stupid and enterprise is not really worth the price for consumers. If you REALLY want encryption, there are software solutions to it that are just more economical. The other features of enterprise and ultimate aren't useful for you.

Pirate windows7 and get windows 10 for free

I found this,
http://www.amazon.co.uk/Windows-Professional-Refurbisched-Hologramm-Servicepack/dp/B00N9VE9CC/ref=sr_1_2?s=software&ie=UTF8&qid=1431888424&sr=1-2&keywords=windows+7+64+bit

Is this good or not?

haha

Holy crap 12 years old and like this? Damn i'm impressed

Ok, first things first:
What made you think you need more RAM?
I don't want to rain on your parade but that pc is 7 or 8 years old. There's a lot more to CPUs than cores and clockrate, but I won't go into that. What I'm trying to say is 3GB is perfectly adequate for that CPU, you'd have trouble running anything that'd need more than 3GB. Even today most games won't even need 4GB. TF2's from 2007 aswell and won't even use 1GB, rather around 600MB.

If you actually need more RAM then the next thing is to find what you currently have.
You'll also want to know what motherboard you got.
You can use CPU-Z for both.
http://www.cpuid.com/downloads/cpu-z/cpu-z_1.72-en.exe
Just download it, put it on a USB-Stick and the install it on that pc.

You want the motherboard and memory tabs. Check in the SPD tab how many slots you have and how many are in use.
And please take screenshots, don't take photos of the screen.

The problem is that the Q6600 can use either DDR2 or DDR3. It depends on what your motherboard is capable of. DDR2 is obsolete and hard to find these days. You can't mix them, so if you mobo can handle DDR3 it'd be best to replace it. Same if all slots are full, you'd have to replace the memory since you can't add any more.

Wow thanks! :)

How?
Also, why?

Microsoft will allow everyone to upgrade to win10, but you aren't going to get a legal version of OS, if you have a pirated OS.

“With Windows 10, although non-Genuine PCs may be able to upgrade to Windows 10, the upgrade will not change the genuine state of the license. Non-Genuine Windows is not published by Microsoft. It is not properly licensed, or supported by Microsoft or a trusted partner. If a device was considered non-genuine or mis-licensed prior to the upgrade, that device will continue to be considered non-genuine or mis-licensed after the upgrade.” says Microsoft.

I don't even want to Pirate it anyways. Good statements doe
