electro.....thanx buddy.....i have 1 last question
my cpu under no load shows temp around 38 celcius and under load it becomes 48-50 approx(i am usinh realtemp 360 to monitor system temp).........so is it a healthy behaviour because my cabinet is also very compact.....and i am using stock fan by intel that comes along with core i3 540..........

It is normal that the 2 cores have slightly different temperature. About 3°C look totaly normal. There is no guaranty that they operate at the same load level.

In your case, with up to 5° difference, I'd suspect that the heat sink may not be properly seated, or, more probably, the thermal compound was not applyed correctly: to much on one side or the presence of an small air gap.
It's also quite possible that one core get tasks that require more processing power then the other. Open the task manager (shortcut: Ctrl + Shift + Esc) and take a look at the graphics on the performance tab.

That said, as long as the warmer one is within normal working temperature, there is no reason to be concerned and you don't need to change anything.

Electro........i wanna ask u 1 more question i have an core i3 540 i know that its a dual core processor......
but can a dual core processor have different temprature like noramlly my core 0 =39 celcius and
core 1 =42-44 clecius is that normal...........

Thanx Electro......it really worked.......it was d moisture that was obstucting my pc from running normally.......i shifted it to a new room and its running like a dream.........thanks man thanks a lot......

A good air conditioner should REDUCE the humidity level in the room.

Anyway, from what you say, it realy look like you have a condentation problem and, as the computer tryes to start, it warm up and cause the condentation to evaporate.

It don't depend on the drive(s) used nor the OS installed.

Is there a possibility that excessive humidity could cause some problem?
**** YES! ABSOLUTELY! ****
Especialy if it's high enough to cause startup problems like yours.

Excessive humidity can realy damage a computer by causing oxidation on the various contacts. This can cause erratic behaviour, random crashes and freezes, and eventualy, total and terminal failure.
It can also cause short circuits that can damage, or even destroy, some components.

The solution: Move the computer in a different room that is NOT climatized.
Another possibility: Cover the computer in some wraping during the night. It can be a plastic bag and/or some blanket. DON'T forget to remove it before you turn the computer on as it will cause overheating.


In another case, it was needed to preheat the computer with an hair dryer for close to 10 minutes to successfully start it...

I have purachased this pc a 3 month ago.......it probably happens when i turn on my room air cooler for the whole night....so it creates a very humid kind of climate in my room.....so when i don't turn on the room cooler in the night.......my pc starts normally with no problems.
i have western digital 500gb hard drive with windows 7 installed on it......
i wanna know is there anything that my pc is facing any problem due to humidity.......

Try using proper punctuation and capitalisation, it REALY help understanding what you want to say.

Some guesses:
Your BIOS support batry is bad and need to be replaced. It's about the size and shape of a nickel.

Your main drive have some problem and don't get to operating speed normaly. You may need to change it.

Some component of the power supply, probably a capacitor, is faulty. This causes a bad power availibility. As it heats up and load up, it finaly manage to provide proper voltages and currents. Try with another power supply.

Some power connector may have worken loose. Check that all power connectors are properly connected in the proper locations.
It's perfectly normal that you have several unused connectors.

If you use a power strip, when you turn off the computer, DON'T power off the power strip.
