Hello,

I've recently built this system, my first build. (see specs below)
The problem is I've been getting beeps/buzz from the onboard speaker.
They are about 1 sec. in length and seem random. Sometimes they are back to back.

Also, the PC will shut off completly with out any warning.

After doing some poking around I was able to monitor the temps. volts. & fan speeds in BIOS & in windows w/Smart guardian.

I found out that the CPU, Chipset, System temps & volts will repeatedly and randomly spike into the red.

For instance the CPU temp may go from 67*F to 498*F for a half a sec. or the DRAM may go from 1.77v to 2.56v. There seems to be no coralation or pattern between the temps and volts nor with the beeping.


BIOS are set to 'Optomize'
No over clocking.
Nothing more than Windows, the net and a printer are running.
Side panels are off.
Room temp is about 71*

Please Help!

Thank You

Pat Zak

When we talk about computers we use celcius to measure temperature. It took me a while to get used to it myself but it is a common standard that we need to stick to.

I would suggest completly cleaning all the thermal compound off of the heatsink and reapply. Also make sure that the CPU fan is running and the heatsink is fully locked in to place.

My guess would be that you used too much thermal grease the first time. This should not affect your RAM voltage though. Go ahead and reset your CMOS when you reseat your heatsink. This is done by removing the battery on the MOBO for a minute or so. Some boards have a jumper that can be remove to clear the CMOS.

500 Watt, Mfg unknown

Did this PSU come with your case? This could easily be the cause of the fluctuation in voltage.

Edit: Just a note your RAM voltage should be 1.9v.

Thanks Titan,

Is there a special compound cleaner I should use?

After watching the Smart Gaurdian for several min. I noticed the following,

CPU, temp varies from 5*c to 256*c, voltage is at 1.26. but can go down to .5 or up to 2.80,
Chipset, temp 56*c Can spike but not offten. Voltage Chip +1.5v, 1.48 norm spike up to 1.8
System, temp31*c spikes to 120* or 250*.
Other voltages, HT+1.2v 1.21 norm may drop down to 0v, Atx+5.0v stays the same at 5.05v,
DRAM 1.77v spikes low and high, ATX+12v @ 11.96 can go low and high at times, ATX+3.3v @ 3.31v norm,
VBAT+3.0v @ 3.05v stays the same.

The PSU is a Ultra 500 watt ATX power supply

[Titan8990]

That PSU has a very low efficency rating which can account for your fluctuation in voltages.

It seems to me like your temperature monitoring program is not functioning correctly if it sometimes reads a temp as low as 5C.

Lets give another program a shot. Download Speedfan (The download link is in the first line of the second paragraph), and install it. Once it's installed, run the program and post here the information it shows. The information I want you to post is the stuff that is circled in the example picture I have attached.




When you clean the old thermal grease off of the CPU use isoporyl alcohol. They make special cleaners but there is no point when you can get isoporyl at your local drug store. Use a lint-free cloth to wipe it off first then use a cotton swap with the alcohol to clean of the remaining grease. Do this on both the CPU and the heatsink.

I cleaned and re-greased the CPU & Heat sink.


OK Titan,

Here is the info. you requested;

Temp 1: 17c
Temp 2: 55c
Temp 3: 31c
HD 0: 36c
HD1: 33c
Temp 1: 17c
Core: 14c
Core: 56c
Ambient: 0c

Vcore1: 1.26V
Vcore2: 1.22V
+3.3V: 3.31V
+5V: 4.97V
+12V: 11.97
-12V: -9.32
-5V: -3.32
+5V: 5.05V
Vbat: 3.06V

The temps are still all over the place, but the volts seem some what stable.

Do you think it may be a bad mobo?
Should I think about changing the PSU? What is a good brand?

Thank You!

Are those temps under load or idle?

Are they still hitting really high temps?

What program were you checking your temps and voltages with before?

[james_8970]

Just to add something here, don't use that Smart guardian program, if it was reading accurate information your computer would be dead now. I doubt your motherboard could even administer 2.8V to your CPU, thats over about 1.5V over stock, easily enough for fry you chip in a very short period of time and temperatures of 256*C are also unrealistic.

Are those temps under load or idle? No real load! Just normal Ops.

Are they still hitting really high temps? Not as high as before, but still all over the place. Temp 2 @ 56c, Temp 1(6th line down) @ 127c, & the second Core @ 57c, seem to be the constant highs now.

What program were you checking your temps and voltages with before? Smart guardian

While I appreciate all your help guys, It always seems that I get the bogus products that never perform right.
I guess I'll be in the market for a new MoBo & PSU.

Thanks

Pat Zak

[james_8970]

No, I think it's the software your using, not the hardware.
Try core temp.
James

[eZAK]

Ok, I took your advice and downloaded 'core temp'.
It shows core #0 @ 6c, & #1 @ 15c.

Now, I may not be as smart as some of you, BUT running three temperature programs with different results, beeping from the MoBo, and a periodic shut down, leads me to believe there is a problem with the internal sensors inbedded within the board.

Couple that with a low end PSU and things could get dicey.

This however is just an opinion, and I could be wrong.

I would however like to find a cause & effect which results in a remedy.

Thank You

[james_8970]

Can you give me the model name of your PSU?
What programs have you downloaded, the temps that are being recorded are very, very odd.
James

[Titan8990]

The PSU is a Ultra 500 watt ATX power supply

It's the one that got poor reviews in the recent analdtech review....
