Performance Issues on WIN7 Computer

[NoActualName]

Hello, I came here in the hopes that someone may help me determine a potential fix for the problem which I am currently having from my desktop computer; or some diagnostic program I can use in order to determine the underlying issue which I am experiencing.

To briefly explain, I am experience stuttering which has random intervals. This occurs during video streaming, gaming, as well as when there's nothing going on; whenever I'm on the desktop. As you can imagine, this is extremely irritating.

I have scanned the system for any potential of viruses, malware, spyware and have come up with nothing. I have fragmented my hard drive, and it should be noted that the hard drive is new and freshly installed with windows 7. I have ran the disk checking utility program, and it came up with no issues. I have updated my graphics card as well.

I had my computer sent off to the repair shop to install Windows 7 after having a new hard drive installed; and once I had it returned to me, it came with this stuttering problem. Is there anything I can do other than send it back to the repair shop?

Hi and welcome to SevenForums,
Please make sure your system spec's page is correct,
Your not showing a antivirus program :/
Does that mean you've been streaming videos and playing games without one :shock:

Sending it back should be done if a warrantee was given did they install the video card ?
Again warrantee

I've been using AntiMalwareBytes.

And I think you misunderstood, this isn't a recently bought PC; it's one I had for about four years, I've just received it back from the repair shop which installed Windows 7 on my newly installed hard drive.

Thanks please still use the link above my signature to fill in your system spec's for the machine,
If you have onboard graphic's remove the card and test the stuttering,
Also while you have the panel off check the connection to the hdd and power and motherboard to see if they are loose,
Cheers.

Run this program and see whether there are any red bars. If yes, take a snip of the picture and post it here. That should be run when the problem occurs.

DPC Latency Checker

Here you go; it seems to occur randomly. Red bars seem to appear even though I am not actively doing anything.

Edit; as suggested by the program, I individually checked each device via disabling and enabling 'em whilst monitoring for any spikes. And I have come to the conclusion that it is my network adapter that is causing these spikes and have noticed that there was no audio or video stutter when it is disabled for, as far as I observed, five minutes.

Now the underlying problem is that I do not know what to do from here, as when disabled, this cuts of my internet and thus cannot proceed to my daily activities of watching videos and otherwise surfing the web. What can I do to remedy this, if it helps, the network adapter is called "802.11n Wireless LAN Card".

You probably have a generic Lan driver. Look on your manufacturers website whether they have a driver for the Lan card of your model PC. Then install that. But at least we narrowed it down.

I've went ahead to ASUS main site and searched for drivers for my model number and found drivers for LAN, and so as per your suggestion I went ahead and installed that. Rebooted, and went to device managers and it isn't there. I then went to install the wireless one, and same result, reboot, and it's not there. I don't know whether it's something I'm doing wrong, but yea, I can't seem to install another network adapter.

See picture.

Just a point, Malwarebytes is not an antivirus program. You should install one.

I have attempted to do as you had suggested, although it did not work. I right clicked on the 802.11n, went to properties and then to driver, I then browsed my computer for what I had downloaded and it just said that "The best driver software for your device is already installed."

I've also attempted to update it via the "Let me pick from a list of device drivers on my computer" option, and I've managed to bluescreened after various options taken from the Asus category.

That is strange. I wonder whether something is wrong with the hardware.

1. Download and run the Process Explorer: Process Explorer

2. See whether there are any interrupts - especially DPCs (deferred procedure calls). You see more details when you right click on the process and go to Properties.
