Computer Starts But Turns Off After 5 Seconds

RE: Computer Starts But Turns Off After 5 Seconds
if it turns out that the new psu still does the same thing, i would try Rap's suggestion and set BIOS back to default because a too high voltage on an overclock can have the same symptoms. easy to do, if there is a clear CMOS jumper on the board, strap it over for a couple of seconds or remove the CMOS battery. even though you had it overclocked fine before you moved, cpu overclocks can degrade over time and may require a lower voltage adjustment.

I just reset CMOS (pretty easy to do on this board - there's a button on the back panel) and it has not had an effect. So that alone does not appear to be the problem. The new PSU should arrive tomorrow morning.

Just out of curiosity, if the new PSU doesn't fix the problem, and I have to get a new mobo, what do y'all think of this one as a replacement? (LGA 1155, p67)

I don't care for that brand at all but its cheap enough and probably a safer bet then ebay. I never liked their voltage regulator circuitry. I could go into detail but it would take some time and space. Supermicro is the best I have seen as far as quality and design but they lack enthusiast features. I have many Supermicro P7C67 motherboard's in the field and they are excellent.

You should pull the power button leads off the front panel pins on board and short them with a small flat head screw driver, just to rule that power switch out as well. It will.start right up when you touch the exposed pins

I would never trust a suspect CPU heatsink by just looking at it in the case for what its worth.

What are the system specs?

Sounds like the PSU

RE: Computer Starts But Turns Off After 5 Seconds
I tried jumping the front panel switch. It started, but had the same powering-off-and-cycling-forever problem.

My new PSU arrived this morning. I installed it, and it still has the exact same problem. Plus I don't like this new PSU as much as my old one Sad

So here's where I'm at: the next thing to replace is probably the motherboard. My processor is an intel i5-2500k, which is LGA 1155. The only motherboard that's LGA 1155 p67 (for overclocking) that I see on newegg is the ASRock one that I linked earlier, and which gets terrible reviews. It's fairly inexpensive, but it may also be lousy. Should I buy it and try it? Or should I just say, eff this, and get a new LGA 1150 processor and motherboard? I'd probably get an i5 4690k, and a motherboard to match. What do y'all think?

Thanks!

I wouldnt throw any money at it since you have been overclocking.

I don't understand - you wouldn't get a new motherboard for the i5 2500k that I've been using? Because I have been overclocking it? Are you saying I should get a new processor and motherboard?

Its your money. Im just saying its a flaky board is all and oc'ing can hurt other components as well.

Hello to all interested parties.

Problem fixed! Apparently I needed to reseat the cpu. I did that and it's running beautifully with my old psu. Thank you all for your consideration and help - it's nice to have you guys to turn to when my computer starts acting up.

Peace,

lol i thought you already reseated the cpu when inspecting the socket pins, then i re-read the post.(cpu heatsink mounting bracket pins!)

anyhoo, glad you got it up again...it wouldnt be the first time re-seating an intel chip fixed a problem.

just fyi, a $10 psu tester and a $15 meter will always come in handy when you are a diy'er.
