So i have virgin media and would have 2 PC's and the xbox connected via ethernet. I got a new PC and now we have 3 PC's connected via ethernet and the xbox wireless.

for the sake of the description, lets call them computer A,B and C.

Computer A is my girlfriends computer
Computer B is the Old one
Computer C is the new one

I have set up computer C next to Computer A, both connected to the router via ethernet. Computer C runs smoothly however, Computer A seems to be effected somehow. The file windows and general computer usage seem sluggish now and internet takes a little while to load up.

In games Computer A expieriences latency and Lag, however, Computer C has none of these issues.

Computer B has never been next to any of the other computers and has never caused problems like this.

I have tried on Computer A:
Virus Scan
Defragment
Delete Un needed programs
CCleaner
Driver Updates
Windows Updates

But still problems. The HDD has 700gb spare so its not a space issue.

Does anyone know what i can do to solve this problem? or any kind of diagnostics to run?

Many Thanks
Cain

I do not think this will do anything for the issue. Unless the OP has >100mbit internet connection (or a 10mbit switch in the router) then the 100mbit connection between the computers and the router will have more bandwidth than the internet connection.

Also a network connection would have no impact on opening my computer and moving around on the local hard drives.

Sounds more to me like the HDD on A is acting up. It could be that you physically bumped/moved it and caused damage, could be coincidence, could be that A was doing this before (slow start) and wasn't very obvious until a new/fast PC C was put beside it.

Could also be the OS install, windows does get a lot of crud in it and over time loses performance. A fomat c: and clean windows install could fix it.

Alternatively (and the option I recommend) - get an SSD for A, disconnect the other HDD's (for now), and install a clean copy of windows to it. Once you have a virus scanner and such installed in windows, reconnect the original HDD and make sure the PC boots off the SSD (in case the issue was a virus on the HDD).

How long ago was that and what all has she installed on it? (you don't need to answer this)

Your old PC may have had a few major games/apps installed on it and been used only with those games/apps, while her PC has installed (possibly removed) a number of various applications including a daily background changer, half a dozen chat applications, and this/that/and the other thing. Just because the OS was installed the same time as one on another computer - doesn't mean that her usage was the same as yours or that the problem was caused by those applications.

If you don't want to buy an SSD to try this - an old hard drive would work to test this out too.
