It sounds more likely (I come to this conclusion because you said it stays on when you cut power to the CPU) that your motherboard is cutting power off immediately due to an over heating CPU (allot, if not all motherboards made now have had this feature for some time to prevent the CPU from melting).
Make sure the heat sink it firmly attached and the artic silver paste stuff is applied properly.
Hope you get it sorted, sounds like a crappy situation you're in.

No, not necessarily. Power Supplys die all the time. It could of just been exposed to something that it could barely handle for a prolonged period of time until one day it reached its limit and simply eroded its maximum performance.
What it once could handle, is now out of its ability.

Might be a good idea to take it to someone who know's what he's doing else, it's up to you.
From what I read the problem seems to be the PSU, or something short circuiting, making it go on and off. Make sure that there is NO screws, backplaters or what so ever behind that is in touch with the motherboard. The thing is if you keep booting it and it goes on/off eventually something will really die.
So first Check
- if nothing is touching the motherboard. Screwes, anything else metal.
- Make sure the wires arent touching the case (Pin connectors).
Another way to find out whether something is short curcuiting or not is by removing the mobo out of the case. Place it on a wooden plate, or shielded bag.
Only mem, CPU, VGA, and PSU.
boot it with a screwdriver by touching the PW-R pins (where normally the case Power on is connected to).
If it still does the same, try a different PSU.
I doubt its the CPU as you first have to do the power on/off button at the back of the PSU.
Especially if its a decent PSU it will have protection at this kind of matters...
Post the system spec's. Might help alittle.

I assume those were el cheapo PSU's.
any decent PSU. Enermax, Antec, OCZ, Seasonic. Usally just dies and doesn't do anything. (If they die after a couple of years) el cheapo PSU's will give strange problems. even BSOD's in Windows just because it can't deliver a stable voltage to the other components in the PC. With all the qaud core, dual SLI, high energy taking graphics. A GOOD power supply is a must.

Expensive solution IMO. (for a decent PSU, that is) Generally the heavier a PSU is the better quality it is.

I did try that Roshambo, sadly no dice. There are no screws or plates or anything in the way, this computer has been sitting stationary for two months and then suddenly a rogue screw decides to jump into the mix? I think not.
This isn't a cheapo powersupply, it's the same one I have in my computer. OCZ GamerXstream 750w.
As far as the HSF coming unmounted again, while stationary. That seems pretty unlikely. It's spinning and while the computer ran his CPU was way cooler than mine, he has a Thermaltake Venus 12+ on there. It's like a vaccuum cleaner. I wish I could get one but I can't afford 40$ for a HSF...
Like I stated in the first post I've isolated it to where I unplug the CPU1 PSU connector and it will run forever, connect it and it runs for a second. When my computer (With the same mobo) died about 6 months ago and did almost the same thing the motherboard was bad. It would just shut down instantly after being turned on however, when I removed the CPU1 connector mine still turned off... His doesn't.
Edit: Here are his specs. He sent me them.

I've lived in 2 different houses over the past 5 years, and BOTH of them simply eat power supplies. I've gone through literally a dozen power supplies. I've had 2 that outright exploded, with fire, loud popping, and smoke. Most of them either die the silent death, or act like described above (power on and after x seconds it powers off).
probably 3/4th of them were cheap shitty ones...for awhile I was buying $30 cases from Frys just to get the 420w PSU out of them (ironically the case+PSU was $30 but PSU alone was like $65 lol). The expensive ones seemed to last longer but they are also the ones that literally detonated when they did finally go out.

I think you might want to look into whats eating your PSUs. I have had this same cheap £20/$35 350w PSU for 4 years now and I have yet to fault it. I have alot draining from it and yet it still comes out on top.
I have
3 IDE HDD, 1 Sata HDD, 1 IDE DVDR, 1 Sata DVDR, AMD 6000+, 120mm Case fan, 7900GS, X-Fi Sound card, PCI Wifi and a few USB devices connected.
Something seriously wrong with something in your computer to make it explode good quality PSUs in a short amount of time while im still sitting happy with this cheap thing.
Dot: As I mentioned before, try it with another PSU.

Well like a week ago i was playing a game and heard a loud pop sound from my computer. Then it shut off like 1-2 min later and when i restarted it it would do the same.
After taking my computer apart i found 2 of the screws that held my heat sink fan on broke. The plastic part that held the screw on the whole thing snapped.
So the screws weren't holding the heat sink fan directly on the psu. And it was over heating and shutting off my computer.
I would check this to if you haven't already.
Good luck

Normally cheap PSUs are worse. It really depends on how it is used.
My tech teacher says that if you are buying a PSU and are stuck between two of them... to go with the one that weighs more. He says because it has more transistors in it and would be more efficient at its job.
|
Your teacher is right, a good PSU does weight alot more.
As for topicstarter, I would suggest trying a different PSU then.

The only PSU I've lost got fried in a power surge (I couldn't afford a surge protector lol)
That same surge destroyed one of my router's ethernet ports, the other 3 work fine (the one that's gone was in use during the surge). Weird, eh?
Renguard is a wonderful initiative
