Shrieking sound and Massive Overheat

[notguru]

I built my PC system (specs are in my signature)
I haven't yet installed Vista Basic x32 or any of the drivers
but when i power on the pc, at the start-up there is an annoying sound and the pc says, "the cpu has overheated"
ironically, i have the HAF 932 case and when i monitor the CPU myself, i find it is only 49 degrees (which is stable, right?)
so what's the deal with this...?
do you think installing OS and drivers will rid the annoying sound problem?

Are you using the stock cooler or an aftermarket one?

I am having an identical problem with a kit i am building (as specified below) - a constant high pitched siren goes off at powerup. I am using the stock fan which came with the Intel Core 2 Duo E7400 Processor. I have checked the mounting of the fan and the therma grease. At initial powerup, the bios tells me that the internal temperature is 35 deg Celsius and the processor temperature is 42 deg Celsius. After about 10 minutes of idle computer activity, the internal temperature is 40 deg Celsius and the processor temperature is 49 deg Celsius.

my system specs:

Cooler Master HAF 932 Full Tower

Intel DG35EC Motherboard

Intel Core 2 Duo E7400 Processor BX80571E7400

XFX GeForce 8800 GT Video Card - Alpha Dog Edition, 512MB DDR3

LITE-On 18X DVD-ROM optical drive

Microsoft Windows Vista Home Basic

Seagate Barracuda 7200.12 500GB Hard Drive

OCZ SLI 4096MB PC6400 DDR2

DiabloTek PHD650 650-Watt Power Supply

I am using the stock cooler, but my case also comes with 3 230mm fans.

What power supply are you using? The diablotek one that suntaclause posted got a few reviews saying that it screeches and then pumps out alot of heat. So suntaclause you probably want to swap out that PSU ASAP. Notguru im hoping you used a good PSU in your build?

Actually no, coincidentally I used the same exact PSU as suntaclause.
We probably bought the same barebones kit.
What exactly did the reviews say? Have a link?

Two of those sound suspiciously similar to the screeching sounds you two both had.

"I am the Tech for my office & staff I support 50+ systems. MY own Home PC went out so I built a new Top-Of-The-Line system. AM3 Phenom II - 3.2Ghz - Gigabyte MA790XT-UD4P - 4Gig RAM 6X 500 Gig HD - 3XSony DVD Burners - ATI AIW X1800XL 6X40mm Case Fans. It needs a LOT of power. This LSP650 boots and runs the whole system Quietly and Efficiently. I have always preferred ANTEC or ENLIGHT but have NO problem recommending these ULTRA Power Supplies now. CompUSA is 2 miles from my home so I compared carefully. For the price, you cannot go wrong. KEEP your receipt as ULTRA requires this to register for your LIFETIME warranty - I registered on-line fast and easy. If this is an example of Ultra's commitment to quality, I salute them. For the price ($70) this is a great P/S. For any future builds, I will stick with these ULTRA Power Supplies."

This was a review for the Ultra LSP650 power-supply. And it had great reviews...:

Are you quite sure it's the PSU?

Same price, better brand, rated slightly lower but will still give you the same amount of power.

Unless the 2 reviews about the whining noise also bought the same barebones kit i would bet on the psu.

We recently replaced a mobo (new one from Gigabyte) and stumbled across a BIOS feature I had not seen earlier. It monitors the CPU fan speed and can be set to put out a loud alarm sound if that fan is not turning. Actually, the alarm means, "I do not detect a fan speed, or it is detected but not fast enough". It does not really mean, "Your CPU is dangerously hot!" This alarm is an option in the BIOS that can be turned off.

What kind of CPU fan do you have? Is it plugged in properly? Check the mobo manual on how to do this, especially if you have a 3-pin fan cable and a 4-pin mobo connector. If that part is all right, try turning off the CPU Fan Speed alarm in the BIOS. It still has a separate CPU Temperature monitoring system to protect from overheating.

I use the stock fan that comes with the Intel Core 2 Duo E7400.
My mobo = Intel DG35EC

Page 33 of your mobo's manual shows how to plug in he CPU fan. I can't find in the on-line manual a direct listing of all the BIOS features, so I don't know if your fan monitor has an alarm function, but the sound you describe seems like it. I also can't find whether your processor came with a 3-pin or 4-pin fan. Usually its connector will only fit on the mobo pins one way, but check that the connector is turned the right way, and is plugged into the right set of pins if it's not all 4.

notguru, I may have solved my problem. I noticed that the noise was coming more from the MOBO than from the PSU. I pulled out the graphics card and the RAM - and when i restarted the computer the siren was gone. I am installing VISTA without the graphics card in place. My card was refurbished and may be the problem. I will see what happens when i plug the card in after the OS install. It seems obvious that the DiabloTek PHD650 650-Watt Power Supply was not the problem afterall. Perhaps you should try this. Good luck! I will keep you posted on my progress and future headaches...

ok, it worked for me. im probably going to get a gts 250 to replace the refurbished 8800gt
