Single Ethernet connected device receiving asinine amounts of latency.

[Alex Michel]

For a while i've been having problems on a single machine receiving spikes of latency in all programs going up to the thousands in ms.


Here are some details:

The duration and frequency doesn't seem to follow a pattern.

I've scanned for malware with plenty of different antiviruses (i only had 1 installed at a time when scanning).

Scanned for rootkits.

Updated my drivers as well as the motherboard chipset.

Turned the firewall off.

Uninstalled every antivirus.

Closed all ports that were open on this machine.

Machine is running windows 8.

Is there a way i can track the source of the latency? Is it possible to identify an application interfering or hidden malware behavior? I've used an AMD computer that had a program which slowed the internet and limited bandwidth and my my problems disappeared when i uninstalled it so im wondering if there are more programs like that. I can provide my router info if it is needed although this problem only happens on this machine and regardless of whether im using a wifi or wired connection.

One last detail to mention is that i haven't updated windows in a while. Nor have i upgraded to windows 8.1.




Edit: I have also tried these steps :
Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

Reset IPv4 TCP/IP stack to installation defaults. netsh int ipv4 reset reset.log

Reset IPv6 TCP/IP stack to installation defaults. netsh int ipv6 reset reset.log


as well as flushing the DNS, disabling SSTP-service, disabling some network device finding services (for printers etc), and used AdwCleaner.

Have you tried other known working Ethernet cables?

Unplug the machine and open it up. Check that all internal cables, plugs, chips, and jumpers are all fully in place and firmly connected. Nothing loose, crooked, crimped, kinked, etc.. Clean out dust, dirt, and debris. Ensure that there is nothing interfering with air flow and cooling.

Use Task Manager, Performance Monitor, and Resource Monitor to look for some app, process, or service taking a disproportionate amount of some resource.

Open the tool window (one at a time) and watch for a while. Let the system stabilize. Then slide the window to the side and begin working as usual.

See what, if anything, changes when the spikes/lag appear. Just be constant and methodical. Make changes only one at a time and do give the computer some time between changes.

I have tried different ethernet cables, cleaning, re plugging the cables, and monitoring with resource manager.

There doesn't seem to be anything in the resource manager that is obviously causing it. Neither my upload and download rates come close to taking up a lot of bandwidth. I do notice that there are many different chrome and svhost processes sending and receiving small amounts of data. Using cports i also noticed there are a bunch of "unknown" processes on ports 80 and 443.

Look at Task Manager and Performance Monitor.

Also take a look at what is being started via Task Manager and startups.
