Please help, Motherboard/cpU problem.

[fujduong]

Hi, I'm new to the forum and this is my first post. Anyway, I was hoping for some opinions from others more knowledgable than myself could give me a few ideas as to what to do with a problem I've been having.

So, I recently put together a system, here's the specs:

MB: Gigabyte GA-G33M-DS2R
CPU: Intel e4300 1.8ghz
RAM: Patriot Extreme Edition 2 x 1 gb PC6400
HDD: 2 x 160gb WD SATA II
PSU: Enermax Noisetaker II 485W

MB, CPU, & RAM brand new, retail versions. HDDs Brand new OEM, and PSU was a retail version used 6 months in a previous system I built.

Night 1.
Okay, so, the system was put together, raid drivers installed, and then windows xp. Then the motherboard drivers, and two instances of Prime95 (one on each core) were run for 8 hours, and then a brief session w/ CPU Mark (score 5800). End of Night 1.

Night 2.
I installed MSN, Winamp, and three other games, all of which, worked just fine.
Then I proceed to install gigabyte's software applications, @BIOS, iCool, FaceWizard, and EasyTune5. @Bios was updated, and then using the updated program, I updated my MB Bios. System was restarted twice, because I'm paraniod like that. I then proceeded to play Shattered Galaxy into the wee hours of the morning.

Night 3.
Came home from work, and tried to turn on the computer. It booted up slowly, and then died, as if the power was cut. There's no time for it to POST because it turns off. The MB restarts itself again, only to be shut down again. This vicious cycle continues until I flipped the switch at the back of the PSU.

After multiple attempts, I unplugged DVD-rom & HDDs, from the MB, same thing. I don't have another PSU to test, but I did try unplugging the 24/28 pin from the MB, and then connected the green cable pin to a black cable pin, and the PSU ran fine.

I've tried remounting the ram, clearing CMOS, and pulling the battery out, but it doesn't seem to change anything. I'm at a bit of a loss, and would appreciate any input.

Most Gigabyte boards have a backup BIOS and the option to boot from the backup BIOS via Jumper settings. Give that a try, other than that it sounds like your mobo could be shorting out. try reseating it.

I've tried to reset the BIOS with the Jumpers, but I don't think that's the problem, because the Motherboard doesn't even POST. No beeps, no errors, or anything. It just shuts off.

I've switched the PSU's to a fully functional one to no avail, so its not the PSU. I've tried reseating the CPU itself. Though I'm not sure what you mean by reseating the Motherboard. Do you mean, like, just take it out of the case and put it back in?

If so, thanks for the tip, I gotta try that. Cute kid btw.

Just incase there's any confusion. Sometimes the BIOS EEPROM will fail. Gigabyte, as far as I know, actually includes a 2nd BIOS EEPROM that you can jumper to boot from if the 1st fails. Not guaranteed to be your problem tho, since the mobo doesn't even POST.

Yup, sometimes that will fix it, make sure it's properly grounded and all the screws are centered in the holes.

and, thanks he's lucky he looks like his mom!

Try process of elimination. Remove/Unplug everything including the video card. Try booting with only the CPU and ONE RAM stick. See if it continues to cut out or stays powered on. Try moving the SINGLE RAM stick from Socket to socket. Try each stick one at a time.

Also you say you don't have another PSU, but do you have another system at all? If you could try running this PSU on another rig you can at least somewhat elimitate the PSU as the culprit.

Also I'm not familiar with this PSU or MB but (I know this is obvious but you know about assuming) make sure that ALL the suplimental power lines are properly connected (some Vid cards have a supplimental power socket such as a 4 pin molex, floppy, or PCIE power connector. Also the four pin 12v power, and or additional 4 pin molex sockets on the mother board.

I've wasted hours on this kind of issue only to find I skipped something stupidly basic like that. It happens.

Good luck.

Hi,

have u allready figured out what was causing this issue? I am just wondering as I have exactly similar problem with same mobo.

 

[Jschmuck2]

Sounds like a bad mobo dude. Like the Oatman said - process of elimination. If I had to guess though, I'd say a poorly mounted motherboard...maybe it's grounded.

 

[Kuha]

Ok,

I have taken mobo out from kabinet. taken all extra out. Still same issue. I think it's mobo. I took both memory stick away and started. No beep's, just silence. You would expect to get at least some beep's in that case.

 

[Jschmuck2]

Wait. Weren't you someone different before?
