Windows 7: C drive (OS) taking more memory

C drive (OS) taking more memory

Its been 1 week i got my new gaming laptop, it had 2 partition C drive and D drive, my problem is with the C drive containing OS, i want to keep it free from any major software and memory for smooth running of my games.

MY C drive total space is 119 GB, after updates and one single game installed Diablo III, and no other heavy software it was taking 55 GB of memory, 64 GB free, suddenly since last 2 days my c drive used memory shoots off to more the 75 %. i deleted my restore point and got some 2 GB free but its still more then half of the memory.

1) I really cant figure out why and how it happened.Is the system restore point taking the space ?
2) can i make default save location of system restore files to D drive.
3) Installing software like 3D Max, CS5, Autocad 2012 in D drive will effect the running of these programs

Please anyone can guide me through this, m not a computer expert but i understand the basic of it

I'm not a computer expert, either.

First thing I'd ask that you do is provide your system specs. At the top of any page click on "User CP" and then in the left column click on "Edit System Spec". If you don't know all of the info a free tool called Speccy can help.

The next thing is to provide a screenshot of your Disk Management. This will give a better idea of how your hard drive is set up. Please make sure you maximize the Disk Managment screen before uploading the screenshot

Not trying to be critical but just to make sure we're talking about the same thing, memory isn't the same as free (or unused) disk space. If I'm understanding things, your C: partition has/had a total of 119GB of free space. The OS, Windows updates, restore points, and Diablo III were installed taking up 55GB leaving 64GB of remaining free space on C: partition. Then for no apparent reason, "c drive used memory shoots off to more the 75 %." Is that 75% of the original 119GB or 75% of the 64GB? That screenshot of Disk Management will be really helpful.

You have 16 GB of RAM.

Do you use hibernation?

If you do not, you can get rid of your hibernation file and save 16 GB of space on the SSD.

To do that:

Open an elevated command prompt.

Type "powercfg -h off" at the prompt. Hit the enter key. Close the prompt window.

You can also check and control the amount of space used by System Restore.

I don't see why you are so concerned; using HDD space will not affect performance. You can stop worrying about it. Nothing is wrong.

I'm not sure if System Restore space and hibernation file would be included in that 42.34.

You could temporarily turn off hibernation and/or reduce System Restore space to see if used space declines.

And then turn hibernation back on and revert to the original System Restore setting after the experiment.

You need your Restore Points. You should add one back immediately. If something goes wrong you will need to Restore. I add a new one each week to be sure I have one that is current.
