Quick update, I've pinned down the exact issue. It's all to do with my CPU usage. The higher my cpu usage the more interference it causes. E.g. 100% CPU usage = complete black screen, no signal received at all. CPU idling, e.g. 0-20% CPU usage, interference is medium, to nothing. I've checked, and it's not the CPU fan causing this. Think it might be time to buy a new motherboard and CPU

I have no idea when the current was going when it wasnt being touched. However, the issue is fixed now, but the only last thing I can do, is reinstall my water cooler to see if it was that causing the issue. If I install it again and it's fine then we know it was the lack of washers.

Thank you for the help solving this though.

I have now fixed this interference. A couple nights ago I resat my motherboard and used some homemade cardboard washers (probably not a great idea, but they're washers at the end of the day) and I also uninstalled my H40 water cooler for the original stock cooler.

I'm guessing that the H40 was causing the issue as I'm pretty sure my washers are good for nothing. However, I plan on reinstalling my water cooler this weekend and testing it for interference again.

Is this something that could have caused the interference or is it most like the washers?

Thanks for your help.

I think I'm going to have to go dig them out of the boxes now. The family wants to watch tv right now, but can't due to my PC.

I've found out though, the interference goes, when I touch the back of my case/unplug the cable and quickly reattach it.

Definitely has to be a grounding issue here somewhere.

I thought that the washers were literally just to stop you tightened the screws to tightly.

Just got home and I have seen that I'm not using the washers on the mother board.

Is this enough of an issue to warrant me getting/finding some more to try and fix the problem?

I will check these motherboard washers when I am home.

I already have a antenna booster, as I live in the middle of nowhere ha.

I will also check the DVI cable from my graphics card and also try it with a VGA and HDMI cable to see if it's perhaps a dodgy DVI lead.

If I can't get these sorted, Ill look into getting some ferrite chokes and perhaps getting the wiring sorted.

Thanks for the advice.


Yes, I am using Freeview service as Analog has been switched off for almost 2 years where I live.

All the cables to the TV are seated correctly and the setup has not changed at all over the last years.

The computer case is always shut when I use it. Hmm, I remember taking off the paper washers (I think they may have been some sort of rubber) off my board in the old case, but I don't remember adding them when I put it into the new case. I will check this when I am home.

Will this washer thing cause this issue? If so, are these easily buyable?



(EDIT: I've just read that sometimes you should not use these washers with a motherboard. Could it be worth taking them out and trying it then?)

Thanks for the reply. I have remembered though, that I did originally keep the old PSU in place. Then after a week of interference, I replaced the PSU thinking it could be that (an upgrade was needed anyhow).

What I have discovered this week is that, the intereference is most signficant when I play games, usually Battlefield 3 or Fifa and the interference can be temporarily fixed by removing the DVI cable from the graphics card and plugging it back it. I'm guessing I could need to get another, better quality (shielded etc) cable?

I've tried removing the fans etc and this doesnt seem to sotp the interference, however, I've not tried removing them whilst gaming, which could give another lead.

Thanks for the help


Yes, you should be able to, but I didn't realise this was for C. However, I've not used that library before, so I can't really give any help/advice on it.

To shut down the computer on Windows, you can use this line. The system command works like the command prompt and will shutdown the computer silently.

system("C:\\WINDOWS\\System32\\shutdown /s");

From what I understand it is not easy to obtain and change your fan speeds without another plugin/library.

This is the code I've used before in C++ to eject the CD tray, it's not great, but can sometimes work.

#include <windows.h>

int main(int argc, char *argv[])
    mciSendString("set cdaudio door open wait", NULL, 0, 0);
    return 0;


I'm guessing this error is fixed but it is mainly to do with Joomla rather than the HTaccess. What happens is that Joomla will look for similar categories to check that it's not misspelt.

However, with your first link you include a file type at the end (.html) which forces the web server to go to a direct location and bypass Joomla. As you don't have that page on your server you will receive the 404 error.

This could be redirected to a proper 404 page by using this command in your htaccess:

ErrorDocument 404 /404.php

Change the "/404.php" to your 404.php in the root.


Yes, all the internet in the house is wired to the modem, which connects to the telephone line. The TV and modem are about 5m away from each other, but I don't believe this is the problem as I have unplugged the modem whilst receiving the interference with no joy.

The PSU is brand new, so I'm hoping this is not an issue. Is there any way to test what could be causing the interference, eg the fan or PSU, or is it just a case of unplugging everything and plugging stuff back in one by one?

Thanks for the help.

I am experiencing a weird problem with my computer. When I turn on my computer, it interferes with my TV downstairs and it won't receive any signal on a handful of channels (ITV, ITV2 and a couple other channels)dunwe. This issue has only happened when I moved my computer into a new computer case, with a new PSU and computer fans.

This problem is most noticeable when I am playing any computer game (I can't view any of the selected channels at all), which leads me to believe it's related to perhaps the GPU fan causing interference. Whilst playing, I have tried unplugging all my inputs which makes no difference at all, the tv still won't receive any signal.

I am using a TV aerial which is kept in the Loft and the TV is kept downstairs. I have tried using different plugs, cables, power wires and even a new monitor cable. My internet connection is by ethernet and we have no WIFI in the house.

One last thing, I hear a very quiet high pitch sound coming from my PSU, I'm guessing this sound is normal, but I am not 100% sure.

This will apply the css to any submit buttons that use the class "btn" rather than just links that use the clas btn.

Ok, I changed the WAN port on the Belkin to

I then tried trace routing the however, it quickly finds my pc's local IP but then it cannot find

I do not have an option on my Belkin to ping/traceroute.



No worries mate, I hope your feeling better :)

I have checked the wires and they all connected and the lights are lit.

Whilst pinging, I can ping the local port, the router, the WAN port but not the home hub,


After I changed the DNS settings the router's internet light now lights up and says it is connected on the router's settings page. However my computer can still not connect to the internet as it cannot ping the Home Hub and on the network device it says IPv4 - No Internet Access.

The Ethernet cable is connect to the WAN port on the router.

The settings that the router currently has are:
IP -
DHCP - Enabled
SubnetMask -
Wan IP -
Default Gateway -
DNS Address -
NAT - Enabled.

My pc's connection says
IP -
Subnet Mask -
Default Gateway -
DHCP Server -
DNS Servers -,

I'm pretty sure I've made a silly mistake here somewhere!

Cheers mate.


Thanks for the great explanation, it fully described the problem well.

First I tried the first solution that would not enable file sharing. I gave the Belkin it's default IP of and kept the BT Home Hub at - both are on a different subnet. I then made sure DHCP was enabled on both and I connected the Ethernet the WAN port and to the Hub's lan port.

When I connected to the Belkin, it only assigned me an IP being 192.168.2.X. When I checked, I could see that it was not connecting to the hub.

So I went into my Belkin Home Page to look at the settings and I noticed this:

WAN MAC address
Connection Type
Subnet mask
Wan IP
Default gateway
DNS Address

If I read your previous comment correctly the gateway should be I also believe these settings mean that the hub isnt correctly connected to the Belkin. I have checked the ports I plugged the Ethernet into on the Belkin in the "Connection to Modem" port and into a LAN on the HUB.

When I try disabling the NAT and DHCP, I have to assign an IP manually as it will still not connect to the Hub. I have tried connecting to both the WAN and the LAN port on the Belkin with no luck.

Thanks for the last reply, I appreciated the in-depth explanation



I have tried using the Belkin by disabling the DHCP and setting the IP to (Hub's IP is This still wouldn't assign my computer an IP.

Im not sure how to turn off the routers capabilites - I thought this just referred to turning off the DHCP?

Currently I have a BT Home Hub 2.0 downstairs which is connected via Ethernet upstairs to a Belkin G Plus Mimo Router. However, when I connect to the router from my pc, it cannot connect to the internet nor see the BT Home Hub.

I have changed the IP settings on the Belkin router however I can still cannot connect to the Hub. I have also tried using crossover cables, normal cables and different network cards.

The default IP for the Home Hub is: with a subnet
I have changed the IP to the Belkin router to: and kept a subnet of and turned off DHCP Server. I have then connect the two with an Ethernet cable in the router's lan ports.

Does anyone know how I can setup the Belkin so my pc can see the BT Home Hub and connect to the internet.
