Hey guys, couple months back my computer went down on my wife. She was working in lightroom and had an internet browser open. Not gaming or overclocking. it just went black, no shutdown nothing. one second its on, the next off and wont turn back on. I look around and don't see anything wrong with the motherboard that was obvious. my CPU is a corsair water-cooling system so didn't think that overheating was likely. so I purchased a new PSU. The new power supply provided the same results, but failed the paperclip test, so I RMA and got another one in. Same results. no life other then a little twitch of the fans when the power first cycles through. so I pull the board and find a capacitor the looks to be leaking. the board has a shiny puddle formed underneath it like it was waxed or something. quick Newegg search and the reviews agree, the board is crap. 9 months to a year and it died. So I pick up a new board and throw it in. I keep the new power supply as well. so new power supply and new motherboard. computer starts up fans a spinning and no signal to monitor. I try HDMI, DVI, VGA, a second graphics card, a second monitor. No signal. so RMA the motherboard and get a new one. the exact same symptoms. no video no matter what I do. I'm stuck. what is the possibility that the original motherboard actually fried my CPU? this doesn't make sense. without over clocking or overheating it should be fine. ive tried running with just one stick of ram, tried different gpu slots, tried my old power supply, checked the CPU for bent pins, no discoloration, made sure I hear the watercooler running and that checks out. im down too it has to be the CPU. but don't want to waste my money. I need to know why did the CPU go. could the motherboard fry it, or should I be looking into something else. with a new PSU and motherboard, if I replace the CPU I've basically rebuilt my entire rig. So any suggestions?

oh yes if a board goes out, while power is full applied, you have no idea how easily it can short lines and fry a cpu. and "fry a cpu " is inaccurate, it is just a messed up function, item inside the cpu, and it no longer able to function properly.

if you changed CPU, Motherboard, Disconnected everything from it, and all is left is the cpu, by troubleshooting methodology, one would need another CPU to test your PSu and motherboard to ensure they are working , if it does, then your CPU by elimination is faulty.

as to how..? that would require to tear cpu chip down...

only as of like last week since ryzen came out. it has more then enough balls to handle the photo editing needs that my wife has. plus I've already stuck a couple hundred into trying to get this back up and running. if anything, help me get it up so I can sell it and build something worth posting about.

No, its been out of date for a few years to be honest. Even when it was new it couldnt match the Intel CPUs at the time.

But anyway, if you have tried other motherboards, it certainly sounds like the CPU is fried.

oh I see. ok, ill rebuild my 700$ AMD system for a 2000$ Intel system for my wife to edit photos. honestly I expected a little bit more professionalism off this forum, and not to get into a Intel vs. AMD battle right off the get go. I know more about computers then all my friends, and its hard to troubleshoot with them when there looking at me like im speaking a foreign language.I just needed some help thinking through everything so im not wasting money by forgetting about things.

but anyways, cool thanks. ill replace my cpu and just be done with this.

Weird one this , the MSI 990 board you've replaced is far far better quality than those 2 replacement boards you've bought.

The Asus r2 is passable , if you still have the g43 you should return it instantly because its one of the biggest piles of crap there is
Regarding CPU , in all honesty without trying another one there is no way to troubleshoot at all.

6300 is $75 on amazon at the minute , as a replacement (if the CPU is faulty) you're not going to do better for the money.
To all intents & purposes it'll perform exactly the same as the 8320 did for your uses.

Your computer is out of date. I suggest a rebuild.

I'm not an idiot. I didn't build a subpar computer. I built what she needed. your honesty is not welcome. Building a computer that far exceeds the needs of a person isn't being professional. Its wasting money on specs that will never be used. The truths your speaking of are invalid based on the circumstance. They may be factual, but that's not something I didn't already know.

madmatt30 has a great suggestion and cheap too boot. something I would do to test it.

Thank you madmatt30! Im aware of the quality of boards and will be returning the msi. I picked it up because it was cheap and I wanted to verify that the motherboard was the problem. I still have the asus. I appreciate your response, and ill definitely look into that.

:lol: The difference is mine still works. I was only making the point it wasn't a good idea in my opinion to continue spending money on a computer thats already out of date.

Anyway, good luck.
