Question

PC slows down and games start to lag

My PC games like fifa 11, nba 2k11, assassin's creed start lagging today. It only started lagging after the match started (no lagging before menu screen) . It is not my pc spec that cause the lagging because I played these games for a whole month without lagging. I also noticed that my computer is a little bit slower than usual. I think the last thing I did is my assassin's creed crash and i pressed the power off button. The first around 8 times I played it, it didn't crash but after that it always crashes after 30-40 minutes i play. So I don't know what to do and press power off button, then wait for a while then press on again. And there is some new problem occur. When I'm watching video using chrome, sometimes it lag or just got no sound when the video is playing. Is it because of the graphic card or virus? I already scan with avira, malwarebyte and spybot. There is no virus according to them.

Clarification Request
Try a test

I note you are using Spybot Search & Destroy.

Try uninstalling that, (disable the TeaTimer background scanner first), and see if anything improves. We find that, with today's anti-virus scanners. some combinations of anti-spyware become toxic. I know you said this only started recently, but this would be my first test.

Is Assassin's Creed a game that needs an internet connection? if so, and if the lagging started today, try later. It could be a problem with AC's servers.

Hi Mark, already uninstall it, nothing changes. My friend just drop by to check my pc out. He say he confirm that its the graphic card which cause the problem. He say my pc has switchable graphic cards (intel and nvidia). It is now running on intel graphic card but we both don't know how to change it back to nvidia. Can you help me?

Time to check the laptop's manual.

The last time I looked, that model's "switch" was automatic. If if did use the intel the speed from my experience was so slow you would not call it lag but much worse.

Just last week my gamer friend was complaining about lag. It took a moment to find out that the antivirus was performing a disk scan so there it was. A nice easy reason. After a few hours the scan was done and it worked fine.

However I find many computer owners are turning into simple users. That is, they don't want to know how their machines works. My gamer friend is on the verge of that problem. I fear they'll soon have to move to some PS3 or Xbox.

We already did check the manual.It does not say anything about graphic cards.Is there a standard way to do it for all laptop?

Remember I don't see a link to this product or manual.

For now, for most machines it's automatic. Without links it's tough to see if it's documented otherwise.

Had The Same Problem

I had the same problem as you and I found the solution actually yesterday. I was using the crappy Intel graphics card and didn't know how to switch it until I just started fiddling around on my computer.
So this is what I did:

Right-click on your desktop and click Configure Switchable Graphics.
I don't know if this is like this for everyone, but then when a window pops up theres 2 different buttons, the Power Saving GPU (Intel graphics) or the High performance GPU (for me is ATI Radeon, for you is probably nvidia). Click on the high performance one and it should work.

The thing is I don't think everyone will have the same thing, like I don't know if everyone has Configure switchable graphics on the desktop. So if this doesn't work sorry, just keep searching on the computer.

There is no ''configure switchable graphics" for ASUS. Is there such programme with the same function but different name?

(NT) Do you have a link to the product manual?

what do you mean by link?

internet link? or??

The only area of control I found was

"Power4Gate" which on a stock machine is the Fn+Spacebar combo.

This manual did little else to explain the operations in detail but if I were to look, that's where it might be.

Thanks for the manual but they should have done better than that!

There is nothing about graphic card in power4gear. In my opinion, there is 2 possibilities. Nvidia graphic card is not recognized here, only intel graphic card it is using. ( I tried right-click game shortcut> run with graphic processor> high-performance nvidia processor(default) /integrated graphic ,the two graphic are both laggy in games) But Everything is superb last month, I can play every game smoothly in high graphic. So something must have happened. Another possibility is something went wrong with nvidia card.

Ask the maker

For diagnostics. Dell for instance learned years ago to issue such to cut down unneeded repairs.

After all this we see poor user documentation with possible solutions being to reload the machine to the factory install or have the machine serviced.

Nothing, nowhere shows this model giving GPU controls to the user which is the way it must be if you want a machine that is sold and must not have the users calling in for support.
