oh no the motherboard, cpu heatsink and fan are 2 days old the psu is almost 2 years old.

You did put heat transfer pase between the cpu and heatsink right???

More powerful psu's do not create more heat, they create less.
Here is an example of what i mean-
Psu 1 is say a 200watt and psu2 is a 400watt.
Lets suppose they both generate 50 degrees c of heat at full power.
Now, if we require 200watts of power it means that psu 1 is running at full power and is therefore producing 50 degrees c of heat.
Psu 2 on the other hand would only be working at %50 of its capacity and could therefore produce the 200watts at 25 degrees c.

Its not quite as simple as that but its a reasonable example.

A psu will do its best to produce the ammount of power required.

If your pc is trying to pull too much power from your psu it will produce a lot of heat and wont last long.
If you have a way over the top psu then your pc will never pull more power than the psu can safely deliver so it will stay cooler and last a lot longer.

I hope all that makes sense!!!

To simplify (or expand )

Power needed = Stress given on the PSU and how efficiently it deals with it = How much heat and power it will produce.
But i don't think the temps are as acurate as you've noted... (it would have a base operating temp. then deviate off that, like CPU/GPU temps do)

And to add a common example to rik's ones, say you have a system that needs 310Watts of power and 18Amps on the 12V for the graphics card. You have a PSU thats 300W 12V/15Amps. That PSU will have to work overtime to produce the extra 10W and since its not designed for that, the electrical signal provided will fluctuate so its unreliable (could be spiking (bad) or not producing enough/anything (still bad)). Plus the extra 2Amps needed cannot be produced by the PSU because its not made to produce that amount.
If you're lucky the PSU will just blow up (providing some free fireworks as well :hotbounce and if you're unlucky the whole PC will go as well.

You can see this in your speedfan screenshot. The 5V and 12V are not providing enough, but still within the safe operating levels. Try doing another reading when you're 2 minutes into a game and it would've been stressed further.. and i agree with rik. I think its time to replace that PSU.. use this calculator to determine your minimum and add 50Watts to it for headroom.

So: the more the PSU can handle, the less stress its going to experience, the more life you are going to get from it. Of course then theres the silly thing of overkill.. 700Watts for a 300Watt PC.....

Temperatures. Yes your CPU temps are a bit high.. open up the PC up and use a can of compressed air or vacuum cleaner and blow all the dust out, especialy on the heatsinks. that should pull it down a bit.

Please use the EDIT button. Its what its there for.

ok erm i don't have dust on it it's brand new lol. So the answer you giving me is to get a more powerful PSU am i correct

In N3051M's post the word calculator is in blue, click on it and it will take you to a psu calculator that will tell you how much power your pc needs.

hmm estimated 133w hmm how do you tell what psu watts you currently got?

133watts isnt that much, are you sure you did it right?

The wattage of your psu will be on the label on the side of it. It will either clearly state the wattage or it may be part of its name - xpower325 for example (i made that one up)!!!

Picture of an old one i had lying around: http://i61.photobucket.com/albums/h47/N3051M/PSU_Lable.jpg
should look similar. You can post those info here if you want..

You can use Everest Home or SIW (Google for the downloads) to help you fill in the blanks on what you don't know about your PC into the relevant fields and don't forget to press Calculate button again after you changed something to get your result (and add headroom). I'm guessing a typical system like you've mentioned should be about the 300w-350w range..

CPU temps we'll rectify later on, since its still within "normal" operating temperatures..

ok i downloaded that program. it pretty sweet cheers. ok now i am getting 199watts i filled in most parts so thats what i got i need to still find out my current one tho.

ok i had a look and it said this on the psu

FSP GROUP INC

max output: 250watts

ooo latest update I have turned my screen refresh rate to 85 hertz and now my game lag is gone and also one of the tempertures on the speedfan has reduced. but i dunno bout the other i just have to continue and see if i come across it sometime. Anyways Thanks for the help anyways I come back if i have any over problems.

Your 250watt FSP GROUP INC psu is what we call a generic psu. Generic psu's work ok as long as the pc isnt upgraded in any way. Psu's are the most commonly overlooked component in a pc when it comes to upgrading.

If i were you i would upgrade to a good 350watt minimum.

i disagree.. FSP is actualy a fairly decent brand according to some review sites, but i'm not sure if it has a 'value' line like others.. although with the power rating shown, as long as you don't overclock or add another power hungry component to your PC it should be fine.

hmm k well erm any good brands that will be good. Plz?

FSP as mentioned above, also Enermax, Antec, Coolermaster, Thermaltake.. plenty more.

Although brand name shouldn't be trusted alone, you have to find out (by research and user reviews) if they are worth the money or not and if the specs meet the specs you need..
