why is my pc buzzing so much, even when playing non demanding games it buzzes. when i remove the side panel the buzzing stops right away, ive held the case in place and that has no effect.
sounds like its coming from the main fan.

ive googled this many times and all ive found is coil whine/loose fan barings and ive listened to each from the various threads and the sound im getting is so much louder, sounds like theres a hornet inside its unbearable.

If you remove the side panel and it stops then you've answered your own question. Try putting like little sticky rubber stoppers or something between the panel and chassis to absorb the vibration.

Is it an alarm sound from a piezo speaker? Your CPU may be overheating. Monitor your temps with HWMonitor and see what they're hitting. If taking the side off alleviates the problem, you may need more airflow through your case. Are your dust filters clogged? Has your CPU fan come loose (more likely with an Intel stock cooler)? For the most relevant suggestions, please post your full system specs.

with the panel on when it buzzes i can push the panel against the case and the buzzing continues, im quite sure its coming from the cpu fan and not not the case. even just resting the side panel against the case and not slotting it in properly causes it to buzz.

its not from any speakers, and i monitor temperatures with speedfan and the buzzing occurs with varous temperatures, all seem pretty aceeptable according to google.

Your motherboard likely has a thermal alarm on it somewhere (or it may use the case "speaker"). Your graphics card may or may not; a low-end one like the GT610 that does not get hot probably doesn't.
If you lay the case on its side, do you get the noise? That would certainly change the dynamic of any dangling wires.

turned it on its side and nothings changed, i have nothing really running (no games) and the cpu fan is going nuts, so loud but speedfan reads the temperatures as absolutely fine, the buzzing has started now too.
if i was to remove the side panel now after a second or two the fan and buzzing would quieten right down, but again the temperatures wouldnt change at all, getting really frustrating.

edit: just downloaded hwmonitor and it says the fan is going 4500rpm

That seems a bit fast. It must be screaming. It sounds like you need to get an aftermarket CPU cooler. I generally recommend any 120mm tower-style cooler other than the frequently parroted Hyper212 EVO. That one is not a bad cooler, however competitors including Enermax, NZXT, Masscool, etc. often have similar coolers (+/- 1C-2C depending on fans) for less money. CM's own Hyper212 Plus, the little-different previous version, is $20 after a $10 MIR (Masscool's is $22; no MIR games). This makes the Hyper212 EVO a bang/buck Loser, and I prefer not to recommend Losers.

i have the option to return it so they can check and repair/replace anything, but thats gonna cost £40 postage and if they think its my fault theyll charge an additional £40, but i dont want to spend 40 pounds when i can just buy a cheap cpu cooler, alas, i dont want to spend money on a cooler if thats not gonna fix the issue. im on quite a tight budget as you can probably tell by the system specs so doing both isnt really an option.

I believe the aftermarket cooler is a good idea for you. If the 120mm coolers are too pricey, a 92mm cooler would support mild overclocking as well, but in my experience that size fan tends to whine under load; that may or may not bother you (probably nowhere near as bad as buzzing), but it did bug me.
For games, when possible, your next upgrade should be your graphics card. You will have no worries about your PSU (what brand and model, not just wattage is it?) if you get a GTX750 or GTX750Ti, which need no external power. Weaker, but still a lot stronger than the GT610, would be a R7 240 or R7 250. Make sure any "gaming" graphics card you get has GDDR5, not the much slower DDR3 (yours is a business / HTPC card, and would have DDR3).

the psu was the default one on the website (dinopc) it has 'CIT' on the side of the psu casing, as far as the gpu goes i was looking at 7750 (only card really within my price range).

also will the new cooler replace my current fan/heat sink? if so is it just a higher quality?

A GDDR5 version of the HD7750 would be a significant upgrade. Even a DDR3 version would be, but be advised you'd be getting an abomination and would not get anywhere near the frame rated you might have seen advertised for a "real" HD7750.
CIT is not known as a quality brand, but should have no trouble with a HD7750. Tom's ran a rig using an overclocked HD7750 that only pulled 113W from the wall.
A new CPU cooler will replace your existing fan. Some will clip onto the AMD bracket, and others may require you to remove that bracket, and they will mount in the same four holes that bracket used.

is it worth 'risking' ebay to find a 7750 within my price range? i found one for £55 but theyre not restocking them for quite some time. also does ggdr3>ggdr5 really make that much of a difference on this system?

gonna need to put gpu off for a little while due to budget, cpu cooling is more important if it gets rid of this noise.
ive been looking around and i think i need an am3+ cooler, best one ive found so far (in terms of positive reviews) is

http://www.amazon.co.uk/Scythe-Shuriken-Cooler-Supported-Sockets/dp/B0069CQ7BE/ref=sr_1_3?ie=UTF8&qid=1403129704&sr=8-3&keywords=120+mm+am3%2B

will this be a substantial upgrade to a basic fan/heatsink?

edit: also will a new fan be all thats required? a friend seems to think maybe the case is 'suffocating' the internal components

The listing shows a rear 80mm fan. Is that not there? Is there a place in the front for another fan? Ideally, you'd want a front intake and a rear exhaust, to generate a flow through the case.
If there's no rear 80mm fan, is there a space for a rear fan? If so, use the largest size it will accept.

i think the 80mm rear fan is where the psu is, theres no additional fan slots that i can see, the front is just a mesh, and the side panel just has a few holes in it.
the fans weve been discussing so far are they not replacement fans for the cpu? will they not be enough?

also i dont think buying a new case is an option as im not comfortable fiddling with the motherboard and such.
