System is going nuts again! HELP!!

CompGee · Jun 17, 2014

Hi, again. My desktop computer has decided to be problematic again. The first thing that happened is that the motherboard died for a unknown reason, then the CPU wouldn't fit, and now with the new motherboard installed and wired up, the new motherboard does not want to run a POST. I suspect that the video cable or the RAM is causing this. The system cannot reset through the reset button even though the front panel buttons are wired up properly.

what are the old and new specs?

Benevolence · Jun 17, 2014

Try running the motherboard with on component at a time. Usually no post is either a CPU, BIOS or PSU issue. Most motherboards will give a beep code if the ram is bad. If you can obtain or make one, get a system speaker hooked up to the mobo header pins and see if you can hear a beep-code. Try adding one component at a time starting with the CPU/Cooler. Hopefully you can isolate the problem. If this has occurred to multiple motheboards with this setup, it is possible that your PSU is causing the issue. See if you can use a PSU tester or multimeter to test the voltages.

How do you make a system speaker (4 PIN) and I don't have a PSU tester or multimeter. Can you build a PSU tester?

EDIT: I have ran the PSU on another computer and no problems turned up.

Hello?

Danbuscus25 :

I REALLY need help FAST! I don't know how many inferior parts were used in this build, but I don't know WHAT part is causing this issue.

what are the specs?

CompGee · Jun 21, 2014

I installed a new ASUS H81M-C/CSM motherboard and a new Intel Pentium CPU designed for the LGA1150 socket. The other components have remained the same. The hard drive is a Toshiba HDS7210010DLE630. The RAM is a Super Talent 2GB DDR3 1333 ST W1333UB2G9 stick of RAM.

im not sure what is wrong, check the psu maybe, and if you still cant figure it out, try calling the manufactures or your build, asus, your ram maker etc.

CompGee · Jun 22, 2014

I am planning on getting a system speaker that plugs into the motherboard via the 4 pin internal header. Maybe that will sort the issue out. I am also thinking about taking the computer to the pros. When I get the system speaker (maybe), I will post back on the beep code!

Benevolence · Jun 22, 2014

Start with the beep code. The speakers are super cheap online. It could be any number of things at this point, perhaps try running one RAM stick at a time?
In a pinch you can sometimes rig your own speaker. I've found that it is easy to rig those speakers in cheesy greeting cards to the headers. As always, consult your MoBo manual for where to hook it up. Beep codes are usually presented in beeps and pauses. In the mean time try to connect one component at a time and see if you can get it to boot/beep. Most of the time it's bad RAM, although your specific case points towards any number of things. Also check your wires for shorts and make sure the motherboard is not touching the case (properly installed in the casters), as a short can also cause these problems. Another visual check you can do is look for bloated capacitors (the battery looking things sticking out of the mobo). The X on the top should be level or slightly indented in. If it bulges out or looks like it's leaking then RMA the motherboard. Sorry I can't be of more help, but there are too many variables to rule out without the presence of lack of a beep code.

That is a lot of info to me! System speaker will be here soon. When I get the system speaker, I will debug this motherboard. Hopefully, it is just bad RAM. Thanks for the info!

Benevolence · Jun 24, 2014

No problem! Post an update and PM me when you've completed the diagnostic steps.

CompGee · Jun 24, 2014

Okay. The speaker should come in today or tomorrow.

CompGee · Jun 27, 2014

Okay. I installed the system speaker, hooked up the computer WITHOUT the hard drives, started up the computer, no beep.

That was with RAM installed, the computer has onboard VGA graphics, tried the speaker BOTH ways, still no go

I think the MB is at fault.

CompGee · Jun 27, 2014

Thanks for the help, everybody! I will have CPU Wholesale Computer Parts fix this problem. Thanks for the help, everybody!

Benevolence · Jun 30, 2014

Was it the motherboard or the PSU?

CompGee · Jul 1, 2014

It will be a week or so before CPU can get to the computer. I also got to see a HDD clone finish up!
