i have 4 gb dominator 1066 ddr2 ram... if u would just guide me in a step by step manner it would be really appreciated
Since you have 4GB RAM, I think it's a good idea to still leave the pagefile (virtual memory) since you could be using more RAM in some cases.
To turn off hibernation and reclaim about 4GB from your HDD/SDD, press 'Start' and then 'all programs' -> 'accessories' -> right click on the 'Command Prompt' -> click 'Run as Admin'. You'll see a command prompt box with admin. Type in "powercfg -h off", then you'll see that hibernation has been turned off and you should have about 4GB extra space now.
To disable debug information logs, click "Start" -> type in "advanced system" and you'll see "View advanced System Properties" in the list appear. Click that. Click "Settings" under Startup and Recovery. Under "Write debugging information, choose (none) so it doesn't write debug information in case the system crashes.
In the same window, go to "System Protection" tab, and click "Configure". Then choose "Turn off system protection".
