Can someone please help with seemingly unsolvable latency?

[Alex Michel]

I've been having problems with latency causing me to reach ping times averaging around the 5 thousands in some programs. It ONLY happens on ONE computer which is wired via Ethernet.


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.

This is what it looks like when i'm seeing 6 thousand-ish ping times https://imgur.com/a/HPfBE




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.




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 before 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.

In this case, is it possible for you to do a clean install of windows? This seems to be more like a corrupt Windows with a rogue app than anything else. Identifying such apps will be arduous and a clean windows install will likely be much easier. Please back up your data in OS drive before you attempt this. Also, by clean install I mean a clean install. No upgrades, no resets, nothing else. You will be surprised to know how many issues get resolved just by doing this.

You can always try updating the drivers and/or trying a different ethernet cable before resorting to more extreme measures.
