When my computer wasn't sending out signal to my monitor I thought it was the graphics card fault as it wasn't working. Then I replaced another graphics card but still I couldn't find any solution.
My PSU makes this weird noise like zzzzz when it is working with the motherboard. When it is working alone it sounds good and gives all the expected voltages because I measured all the cables using a multimeter.
So, I'm thinking that my CPU could be faulty or the motherboard. I'm really confused :??:  . Please help!

When you turn the PC on, do the fans that are connected to the motherboard spin?

I then think your motherboard should be fine...

The zzzzz sound you try to describe is weird. Your PSU shouldn't be making any sounds.

Does your motherboard produce any unusual beeps?

I know the problem is weird too :(  I'm really confused and don't know what is causing this :pfff: .
The motherboard doesn't have a speaker to make that beep sound.

What if some part of the motherboard is damaged?

Well... Not having that speaker is going to make things a lot more complicated... Because generally, when the motherboard is limited by something, the beeping will tell you what the problem is. Without that, we have no choice but to guess... See if you can get a speaker from somewhere.

ok...I bought a motherboard speaker but the speaker was faulty (shorted) so, I disconnected it from its 4 pin connector and I connected the 4 pin connector to another speaker. Then, I connected the speaker to the motherboard and powered up the system. All I could hear from the speaker was a continuous noise like a ground noise.

I also connected an external speaker to the motherboard's 3.5 mm audio output. when I power the system it gives boom sound then nothing after that. There is no windows start-up sound.

TP-Link wireless internet card PCIEX1 is also connected but not working because the card has a green LED which indicates the status of the card and that LED it is not showing its light so, I'm guessing it could be a motherboard or PSU issue? Which one do you think is more likely to be the problem here?

Yeah... CIT is a very low quality PSU. Considering the weird noises, lack of motherboard beeps and your fans actually spinning, the main suspect is the PSU as of now. Whether or not it's the PSU, you should replace it immediately. There are reviews out there that say that this power supply killed their motherboard. You don't want to rely on such a power supply.

As a reference, use this PSU tier list, and note how CIT is under the worst tier:
http://www.tomshardware.com/answers/id-1804779/power-su...

Start with replacing your PSU. I bet your problems will be solved. If not, well, the PSU might have done some damage to other components. Let's hope it hasn't. If you need help picking one, give us your budget.

yeah..may be the motherboard is damaged by the PSU because I checked the voltages in-system by probing down the backs of the 24-pin and 8-pin connectors and the expected voltages were spot on but the MOBO was not functioning properly even though I did a visual inspection on both sides of the MOBO and couldn't see any visible damages :( 

ok I will change the PSU first and see if it can solve the issue. I'm thinking of buying this PSU (Cooler Master Vanguard V850W 80+ Gold Fully Modular PSU) what do you think?

It's a great PSU. A bit overkill for your system though. I don't know if you wish to upgrade in the future, but you really don't need 850W. For your current system, even a top quality 500W is enough. If you want to leave an upgrade path open, I'd say 750W is enough. You can go for the EVGA SuperNOVA G2 750W for example. It has a 10 year warranty.

http://www.amazon.com/EVGA-SuperNOVA-80PLUS-Certified-2...

If you really want a 850W, the EVGA also has the same one in the 850W version, and it's cheaper yet slightly better than the Cooler Master V850. Make sure it's the G2 and not the G1.

In that price range, you'll fall into the AMD category as best choice, which is the R9 290. It performs practically the same as a 780 Ti, but for a lower price. This might help you a bit:

Thanks for the links :)  The R9 290 and R9 290x perform great for the price but I heard they are noisier and get hotter. I need a quieter GPU with great performance so do you think I should just save up some money and bang it on the GTX 780Ti? cos I can wait until I have the money to buy that GPU.

Depends on what you want really...

Different manufacturers use different cooling setups. Some are quieter and cooler than others. Generally, the reference models that AMD themselves make have coolers that indeed allow the GPU to get extremely hot. The manufacturers pretty much always improve on it though. I personally love Sapphire as a brand for AMD graphics cards. You can choose between different cooling options and overclocked versions. Also... The differences in temperature and noise between AMD and nVidia aren't as huge. It mostly depends on the brand of the card. The R9 290x Vapor-X (which is an overclocked R9 290x) performs very well compared to other cards. Note that the stock R9 290x is also on that list, and it doesn't really perform worse than the 780 Ti.

I personally don't think the 780 Ti is worth the price increase. But you can't really go wrong with it, or with the R9 290(x). If you feel safer doing so, you can wait and get a 780 Ti instead.

Sorry I meant to mention the liquid cooler like the Corsair Hydro Series H110 280mm High Performance Liquid CPU and I would like to mount in the front and set it up as an exhaust to prevent hot air building up in the centre of the case. Then, I can add a fan on the top of the case to let cool air into the case. what do you think?

Are the sock fans noisy? If they are yes I would like to replace them and also add fans on the top of the case.

That's kind of a weird setup actually. Generally, hot air wants to go upwards, which is why cases design the top fans as exhaust. I don't think it's a good idea to be honest, although I don't know the specifics. It might be a good idea to create a separate thread for this. I'm not that knowledgeable regarding radiators, since I haven't installed water cooling myself yet. You can also go through this if you wish:
http://www.tomshardware.com/forum/277130-29-read-first-...

As for the case fans, I have the Fractal Design Arc Midi R2, which uses the same fans as the Define R4. I think the fans are quiet, although they seem a bit weak since they don't seem to push that much air. Generally, Noctua fans are a great balance between air flow and noise. The color puts a lot of people off though...

Humm! Ok it's fine I will just install the radiator as it is supposed to be installed but in the front hoping it will fit as it is 280mm.

What you can maybe do is install the front bottom one as intake, and the front top one as outtake. That way not all the heat goes inside the case, and some of the bottom intake will go out through the top almost immediately. The thing is, aside from the fact that hot air wants to flow upwards, the Define R4 is not the best case for mixing front intake/exhaust due to the door being there. You can get buildup of hot air in there.

Well, the case I have (Fractal Design Arc Midi R2) would be quite good for it. Internally it's exactly the same as the Define R4 actually. Anything with a front mesh rather than a door will do as long as it supports the radiator in that location. That means you'll have to rule out any silent cases for that fan configuration. Other options might be;

Corsair Vengeance C70
Phanteks Enthoo Pro (Full tower)
Corsair Obsidian 650D

I'm sure there are others, but that's what I can think of right now.

Ok I have decided to go for the fractal design define xl r2. I though it would be good to share what I'm thinking.
I'm thinking to use 280mm radiator at the top so that clean/cool air can get in freely. And for the front I will use 2 intake fans. At the bottom I will use 1 intake fan and finally at te back there is an outake fan which is already installed by default and that can be used to take out hot air right straight from the radiator. What do you think?

What if I use the front bottom fan as intake, and the front top one as outtake? This actually could improve the air flow because as the rear fan does, the front top fan could also take the hot air that comes from the radiator. so...what do think now? I really want to keep my PC silent because of what I do and same time keeping the air flow good. By the way I have purchased 5 Noctua NF-A14 PWM 140mm fans.

Outtake = exhaust. :) 

Make your two front Fans as intake and position your CPU cooler and rear exhaust fan in the same direction of the airflow.

Which means that, the CPU cooler front fan (facing the your front case fans) should also be intake fans, and the rear CPU cooler fan should be exhaust fans.

This way, you will have a one-directional airflow.

Option 2:

On the top
Installing the radiator in pull configuration, fans being on the top of the radiator (easier to clean dust on the radiator).

Rear fan:
Installing an intake fan to provide fresh air to the radiator.

Front fans:
Using them as an intake fan so that the radiator and components inside the case gets cool air.

Bottom fan:
It's optional.....If there is too much hot air inside the case, it could be used as intake.
