2x Days ago I put all the parts together and noticed when the heart races to do the first power up on the New Build PC I thankfully didn't get a big cloud of smoke. However, the MB goes through it's POST and after about 10 seconds shuts off. It then rests about 5 seconds and does the process all over again continual.
My steps of troubleshooting thus far:
Removed all but 1 stick of RAM
Removed the MB (wanted to see if it was touching anywhere, mystery screw under it, etc) and re-seated it
Began unplugging parts from MB
Video card Pulled
Mouse / Keyboard Pulled
All 3x HD's Pulled
Sound plug to MB pulled
Now just 3x Case Fans & my h80 water cooler for processor are left in case plugged in, + some cables that plug in from the case to MB
I took out my Power Supply from the computer and brought it to Best Buy so they could test it for me (free). They said it looks good. I told the guy my issues I'm having and he suggested I pull the CMOS battery from the MB and try that. Else I got a bad MB.
What else do you guy suggest? My motherboard has these indicator lights by the RAM chips that are supposed to represent voltage (stress on processor) and at all times every single light on my MB is illuminated (representing heavy load). That's why I thought I was getting irregular voltage. The Geek Squad guy said I could have a bad Capacitor on my MB possibly.
I want to ask about the cords from the case that I plug into the computer (Power Switch, HDD Lights, etc). All the cables are white with the other wire being a variety of colors. White = Ground I hope. I've looked everywhere for a detailed explanation on this and never found one.
Also, I haven't popped out my processor. The thing is keyed when I gently set it in and verified that the lever is down and snapped in before I began the process of putting on the H80 water cooler. I'm thinking I don't need to worry about this as being a culprit?
I tried to be as detailed and organized as possible. I have yet to even get into the BIOS--Hell, I haven't even seen anything show up on the monitor yet (thinking it should have after 10 seconds). If my thoughts are correct, your computer won't reset if you have unplugged: video, and no HD's present? It should just idle with nothing to do correct?
I had similar issues (power up, cpu fan spins up then shuts down and repeats every 10 seconds or so) after about a month of using my new build last summer.
I ended up RMAing everything but the HDD and SSD after not being able to satisfactorily identify the culprit. Intel support eventually decided they thought the RAM I was using at the time (OCZ gold at 1.65V) damaged the CPU (or something along those lines)
Anyway long story short I replaced everything and got new RAM and my rig (see sigy) has been working fine since September or so.
Your RAM is not 1.65V so i doubt that was the culprit (assuming intel support can be trusted), but it seems like it may be a CPU issue, since that was the last thing i replaced before the system was working again.
I know from experience RMAing all your parts is a huge pain in the ass but if you havent been able to identify a specific problem (and it seems youve consulted a number of people so far) you may want to start, probably with the mobo based on what you have indicated others have said and then probably the cpu.
Well, I found the solution. When I removed my H80 Chip cooler to check the seating of my chip, I noticed none of my goo was spread and it was in a straight line still and hadn't spread. It turns out that on of my water tubes was resting on a MB capacitor and when tightening it--it never allowed it to touch the chip
When rotating the H80 and retightening, the chip was cooled, the automatic High Temp shutoff mechanism on the MB didn't activate, and I'm now inside my BIOS enjoying a 25C temp and not having any issues.
Thanks for the advice and am sharing my solution in case it helps anyone in the future having a similar issue
