Power Supply/Power surge

[Tjay09]

Hey guys,

Normally can figure things out on my own. But couple weeks ago, My Power supply had a power surge. I tested with an old power supply and it worked. So ordered a new one. Got it installed yesterday and now my computer will stay on for a little then just shutdown without any warning and will restart. I've monitored my temps nothing was over 60 degrees celsius thou. I cut it on when i got today and seen some horizontal lines on the start up and kinda lost what to try next. could it be the graphic card?

Or maybe try installing a fresh windows and reinstall drivers and see how it with that? Its been on an hour tonight and hasnt shutdown on me. 

Any advise would be greatly appreciated.

 

Using A corsair CX750M Power supply.

Did you try a different power outlet or power strip?

I actually plugged it straight into the wall. after that happened once,  it took more of a load before it would cut off. But reoccuring. Im thinking i got a faulty Power supply from amazon. I did some test a bit ago with my voltage meter and its only showing 5-6volts for the 12 volt pin.

I'm seeing it for $80 new, or did you buy it open box?

THere's plenty of good quality gold units around $85

I paid 85$, was supposed to be New. 

 I already submitted a replacement from amazon. Gonna try that. If its the same thing ima get a refund and get it off somewhere else.

It'd just return it anyways since it's just a very average PSU and a bad purchase at that price point.

Impossible.

 

The PC wouldn't even turn on if the +12V was only putting out 5-6V.

@StreetguruI just don't have the money at the moment to have $85 tied up for another month. and buy a new PSU Hints why i did the way i did. Thanks for the help thou!

 

 

@jonnyGURU I checked it a few times came back the same every time.

Are you sure you're on the +12V pin and not a +5V pin?

 

[Tjay09]

Pretty sure. I Just got the new one installed. I took one of the rams sticks out and it ran even longer swapped to other one and wasnt getting any graphics at all. Thinking Ram got damage from the power surge i had with the initial power supply that was installed.

What is this "power surge"?  You mean a surge actually went through your house?  Like a near by lightning strike?

Impossible! You're probably mistaking the 5V (Red) with the 12V (Yellow). Either that or your meter is faulty. 

 

Tell you what, my old, now deceased, Pentium 4 1.5 IBM workstation (Netvista Socket 478 platform) used to have a faulty PSU. 

 

It's 12V rail would deliver just ~11.20V at idle and drop down to ~10.90V while under load, if I recall correctly. And it was plagued with numerous problems. Keyboard and mouse would stop working randomly while gaming, RAM would sometimes refuse to run on start-up, USB flash drives would get corrupted occasionally and often times I'd to press the power button several times to fire the thing up!

 

Long story short, it got very VERY unstable near the end of its life, but I kept it running because its 160W PSU was 100% proprietary and replacements were quite literally nonexistent, being a very unpopular workstation. Eventually, it gave-up. 

 

Poor b@$tard fought for almost a whole year before giving-up! Respect!

 

With that in mind, I doubt a computer can even boot with its 12V rail providing just ~6V.

A month ago i came for lunch started computer up to watch netflix while i ate and hear a loud like pop. and then there was no power. Mind you this plugged into a surge protector when the surge happened and it wasnt storming. So used an old PSU and it worked but didnt wanna use a 450 watt power supply for my setup. Now with the new power supply it just stays on for a little while but then will randomly crash.(This is the second power supply, Both did the same thing, So i dont think its the power supply. But Installing updates even did a fresh install without it shutting down. But once i have like a few youtube videos open within 10mins or so it will crash on me. I tested the ram last night and im not 100% its actually the ram, The ram check i did came back good but still did the swapping.. Im going to take the graphics card out here ina few and test and see if thats the issue. If it is. What would you recommend getting. I cant afford buying a 600+ grahpics card. I havent had this PC but little over a year spent $2000, thinking i wouldn't have to deal with anything like this. This is the first time ive gotten stumped on computer related issues. usually pretty good fixing things on my own. Thanks for all the input guys. I really appreciate it..If you have any ideas what i can test/try let me know please.

So. Took graphics card out still having same problems. Is there a reliable way to actually test ram to see if something is wrong with it? I know one of the ram stick is dead. not registering but 8 gigs now. And double checked to make sure they was seated properly. Ive seen a few good sales on ram for black friday. But i wanna make sure its actually the ram and not anything else. the temps never get over like 40c so im not thinking it could be related to the cpu/cooler..

So I got a new ram kit into today and, Still having the same issues, Not really sure what do check next.
