Boot-up Issues: Mobo, RAM, or CPU?

Hello all,

So over the last two days I've had my computer just run off unexpectedly while playing a video game. A friend suggested it was overheating, but upon viewing temps the CPU remained around 50C and the GPU 90C (which is a bit high). However, I decided it to thoroughly dust it out anyways.

After removing everything carefully and dusting each individual component, I reinstalled everything. After installing everything and trying to turn it back on my PSU made a high pitch noise and nothing else turned on. I unplugged it from everything, connected green/black on 24-pin and it worked fine. I unplugged everything from the mobo and tried just the PSU and mobo, which worked fine. I then plugged in the power cable to the CPU which cause the high-pitch noise and no power up. I tried a different 8-pin power cable from the same CPU and it worked fine so I continued.

I slowly added all the fans and usb to the mobo, and it booted up fine. However, when trying to add the RAM it gave me an error that it couldn't detect the ram. I then unplugged all the RAM and tried one at a time. After plugging in the first stick of RAM, my mobo started flashing a bunch of different errors at me before going black. I tried a different stick in a different slot and it worked and gave me an error that a hard drive wasn't connected. After connecting the hard drive it flashed a bunch of different errors again quickly and went black (without shutting down). It also started to smell like something short circuited.

I removed the stick of RAM and it smelled like it was fried. I'm now afraid to plug any more of my RAM in. This is by far the oddest thing I've ever experience while trouble shooting a computer that isn't working. Any suggestions on whether it was just that one stick of RAM, the MOBO, or the CPU?

Thanks in advanced.

Good luck for that! Usually Motherboard is the main culprit in this cases! but not always.It can be the GPU the power plug that...


It wasn't a beeping sound at all. It was a high-pitched wine that came from the PSU. Regardless:

Motherboard: Asrock z77 extreme4
CPU: Intel i5 3570k
RAM: x2 4GB G.Skill Ripjaw and an 8GB PNY
Graphics: Gigabyte AMD R9 290
PSU: 750W Thermaltake Gold Series

Like I said previously, after it started giving me a ton of different errors rapidly and turning off the second time I haven't tried turning it back on again. Especially now that is smells like something short circuited. I also looked at one the Ripjaws and it looks like the A1 socket of the mobo is fried because there's black scorch marks on a few of the RAM pins.
 
Take out your PSU then find green and black wires from the 24 pin connector it has. Then short this two using a paper clip or a wire to check PSU is working properly. If it does let me know!
 


I already said I tried that in the original post; it worked fine. It also worked fine when only the PSU and Motherboard with the 24-pin were plugged in.
 


Thanks for the suggestions, but it still didn't work. At this point I'm just going to purchase a new mobo and use that to see if all the other components are still working fine. From all the other posts on here regarding computers shutting down mid-game without it being overheating, it appears the mobo is the main culprit. I'm also hesitant on risking any of my other components to a faulty mobo. I'll update later this week on whether or not this solved the issue.
 

Good luck for that! Usually Motherboard is the main culprit in this cases! but not always.It can be the GPU the power plug that deliver power to your gpu. The cmos battery anything can be the problem. You have to go through a lot of process if you want to test them all.
