Unusual amount of Ram being used.Help please

I have a 4gb of ram that runs windows 7 (64 bit) Dell laptop. Now my problem is that my Ram is being used up when i'm doing nothing. I noticed it a yesterday. So i disabled alot of start up programs and restarted my pc. And to see that about roughly 1.25 gb of ram was used after the boot. Nothing was running. I find this a lot of ram to be used up when nothing big is running. When i open google chrome (only have about 3 extensions running) and it would go up to about 1.45 - 1.75 gb of ram. Again nothing else is running just chrome. I ran a virus scan , a malware bytes scan and even a combofix scan. None of the scans found anything wrong.

I can't even seem to play my game. I get about 20 fps on it and drops to about 7. Before i would have around 45-60 fps. So i'm wondering why this is happening. Am i infected by a virus? This problem occured about maybe 2 days ago, i don't think i downloaded anything that would have done this.

Any help would be greatly appreciated.

This is absolutely normal. You are probably used to the old XP nums - but those days are over. Windows 7 does an excellent job managing RAM. Just let it do the job.

Disabling useless startups was a good move though.

Here is my Resource Monitor for comparison. I have only 1 IE tab (the forum) running.

See the problem is when i'm not running any programs the ram being used is very high. Like right now its 2170 mb being used just when i have chrome up.

Chrome isn't the lightweight little browser it was when first released. It's every bit as memory hungry as firefox now.

That's OK. Chrome is known as a big RAM user. You worry too much. Use the IE.
