laptop drives are usually 2.5", you've linked a 3.5" one

That's a 3.5 inch hard drive, you need a 2.5 inch hard drive like this:

You can upgrade you laptop's RAM, it will just take laptop SO-DIMM modules, instead of desktop DIMM modules. Check to see how many sockets it has before ordering anything. However, you probably won't need more than 4gb of RAM unless you're doing extensive CAD work or heavy Video and Photo editing

Okay, thanks for the help. I'm looking to upgrade the capacity. So would this also be a viable option?

Edit: nvm, Above drive looks good.

And about the ram, would adding 2gb be over the top. My computer uses a ton of ram at the moment for simple things like watching twitch, and playing dota. Is that normal, or not?

You posted the same link as the original post. :p

How much RAM do you currently have?

lol thats another 3.5" look at the name of the product "SATA 6.0Gb/s 3.5"". The 3.5" means it's 3.5 inches which will likely not fit into your port.

Yeah ,sorry. I accidentally copy-pasted the same link as before. Edited out. Thanks for telling me.

4.00 Gb (3.75 usable)

Eh, 4 is probably fine. I guess you could go with 8 but keep in mind that laptop RAM is different than desktop RAM (it's smaller in physical size). Typically, there's a panel underneath the laptop that lets you access the RAM easily. Check it out if you're considering upgrading and go from there.

I wouldn't really worry about how Windows utilizes memory on your computer. It does fancy stuff to make sure things are smooth.

.

One last question. I looked up my computer, and its says that the max amount of memory can be 8gb. Currently it has 4. It also says that there are two memory slots available. Does this mean that its currently only using one, or both? Or does it mean that I will have to purchase two new 4gb sticks to get 8gb?

It's probably using 2 sticks of 2GB right now. If you order 2x 4GB, you'll need to get rid of the other 2.

Thanks for the help everyone. Hopefully my computer can last a a couple more days until the end of the quarter, if not I'm screwed.

protip: buy a cheap USB drive today and backup your really important stuff so you don't lose it if your computer dies.

do you have 64-bit version of Windows? If not, you can't benefit from more than 4GB of RAM

Yeah, seriously start backing shit up if you think it's going to fail.

Yes I do. I was looking on new egg and found a 4 gb stick. Its ddr2. I just wanted to upgrade by 2 gb, so If I replace one of my 2 gb with the 4 gb, that should work right?

Would this 4gb stick work in my computer?

My computer currently has DDR2-800/PC2-6400.

Sorry, really my last question.

Yeah, that should work just fine. The only thing you need to scope out for is 200-pin DDR2 SO-DIMM.

Don't buy another RAM stick, you can't use more than 4GB.
You said it showed "4.00 Gb (3.75 usable)" and the screenshot looked like you are using windows XP.
The only version of Windows XP that can use more than 4GB is the "Windows XP Professional x64 Edition" and I haven't seen that on any laptop yet.

EDIT: Checked again is it Windows 7? The harddisk error looks like Win7 with the good old 98 looks.
Nonetheless check if your OS is 64 bit, otherwise you can't use more than 4GB RAM, regardless of how much is installed.

I thought it might have been XP at first, but it looks like he is using Windows 7 from the Windows logos. But yeah, if you're using 32-bit, you can't go past 4 GB.

Sorry for the late response. Just to let you know, it is in fact windows 7 64bit OS. I like to use win 98 theme cause I feel it increases performance.

Then it should be fine. I hope that you don't run into any issue with two different stick (rare but possible).
