The two fans spins fast and makes a noise like an engine running at a high rpm when the computer is executing a task. For instance, when it opens ie, updates virus scan software, burn dvd etc. Please help?

Re: Power supply and CPU fans spin fast
There may be no problem here. Has it always done this? Usually when executing some major tasks the CPU gets hotter and sends a signal that it requires the fans to work harder to keep from overheating. This may be normal.
hope this helps!

Usually there is a fan on the CPU heatsink and a fan in the power supply. Open the case and turn on the computer and use a small timber stick and poke it into the CPU fan to stop it spinning and if the noise stops then this fan needs replacing. If it is OK the the fan in the power supply is faulty. I recommend you replace the power supply because there are dangerous voltages inside this power supply.
Yes, open the side cover and determine where the noise is coming from - Harddrive, fans, DVD/CD player, etc..
If it's the harddrive, start backing up your important data asap before it goes out completely. If it's a fan, power down the computer and clean the fan. If it's t DVD/CD drive, replace the drive.
Most fans are "temperature-sensitive" -- if it is sensed that your computer is close to over-heating, the fan will run at full speed, very noisily, to try to cool it.
So, shut it down, and disconnect the AC power.
Remove the side-panel.
Purchase a can of compressed-air.
Give the computer a "blow-job", to remove excess dust,
since the layer of dust is acting like a blanket,
keeping heat inside your computer.
this sounds like the hard drives working extras hard. can be caused by malware and viruses as well as anti virus software and realtime protection. the computer might also have a bad bearing in one of the computers fans when you shutdown and power backup listen to the back by the power supply. see if its coming from their or from the cpu cooler. replace as necessary.
There are three things you need to have a good gaming computer, fast graphics card, fast CPU, and lots of RAM. You didn't list your RAM so I can't help you, but 4GB is the most you can put in a computer. If you want to know everything about your computer then click on Start>Accesssories>system tools>system.
Ok you asked four or five questions so lets start with the CPU since if that breaks nothing else matters. First, the measurement for CPU is GigaHertz (GHz) not rpm. So it looks like you have a 1.98GHz CPU. That is not extremely fast (my Dell laptop for instance has a 2.4GHz) so you don't have to worry about your CPU overheating. Yes, all CPUs should have a heatsink and a fan. It helps with the cooling. A CPU also does a thing called "throttling" if it is getting too hot it slows itself down to cool off. So you are good with the CPU.
The other fan is the large fan you hear going on and off. That is connected to your power supply. The measurement for that is in wattage, it is custom made depending on the motherboard so that is a given that there is no problems with the power supply.
Both fans on the CPU and the Power Supply will turn off and on as they get hotter then stop when they are cool again.
Your graphics card is the most important for gaming. It should come with its on RAM and it's on fan. GE FORCE makes some good ones. Just google "gaming graphic cards" and you'll get an idea of what you need.
So that's it. Hope this helps you understand more. If you have any questions let me know. Don't forget to rate this solution with four stars before logging out.
If you changed out the power supply then the only other device that could be making that noise is your CPU cooling fan. To be sure, open the case and disconnect the CPU cooling fan plug from the motherbrd (MAKE SURE POWER IS OFF) and see if the noise stops. Don’t worry about the “Fan Failure Error” when you turn on the computer. Just hit F1 to continue. Don’t leave the computer running without the fan plugged in longer then necessary. After tying this procedure, please contact me for further diagnosis.
Any fan that is making noise you would need to replace. There is also never a need to use alcohol to clean a fan. Some computer air or a light wipe down will do just fine. If you have any other questions let me know. Thanks, Lee
when you say "the fan makes a noise like its getting ready to spin", which fan...power supply's or cpu? if you answer power supply, then the POWER OK signal is not returning to power supply and it then quickly shuts down to prevent further damage. double check a firm connection to mother board.
If you answer CPU, then it becomes far more complicated. Try re-seating the memory chips.
