Hey guys, three years ago my brother passed away and I ended up getting his PC, he was running an i7 2600K @4.8GHz, ASUS P8P67PRO Motherboard, Corsair RM1000, and two GTX 580's in SLi, so not a bad PC, albeit needing a GPU upgrade. Now it ran perfectly fine for about a year, then while running 3DMark Firestrike it shut down and hasn't ran since, the PSU was getting on so i replaced that hoping for an easy fix and it was still completely dead. When you hit the power button the fans turn briefly, the PSU clicks, then powers off immediately. The only way to get any life out of it after this, is to turn off the power supply from the mains and turn it back on again, which lead me to believe that maybe the motherboard was faulty and it's putting the PSU into some sort of protection mode. I managed to find a second hand working motherboard (ASUS P8P67EVO) locally which i've installed tonight and guess what, same problem, instant power cut and no life at all. So now I'm thinking maybe the CPU has died, is a dead CPU something that can cause issues like this or have I just been unlucky with the replacement PSU?
I probably could of worded it better but I'm kind of implying that the replacement PSU may well be at fault as well, I just don't want to invest in another PSU only to find it's the CPU that's toast
Could be anything. Mainboard, RAM, CPU or GPU. You'd need to test each one individually. You need a second sandy bridge mainboard though, to test the CPU on.
i agree with that.., maybe faulty BIOS mainboard ?, i had a similar cases with chipset P67 after updating BIOS, it's won't boot at all.., i reprogram the IC's with CH341A 24 25 Series EEPROM Flash BIOS USB Programmer, and it's working fine right now..
As stated in the original post, I tried another motherboard last night with the same result. RAM has been tested in my main PC and ran fine, the GTX 580's have been replaced by a GTX 780Ti, only thing I can really think of is either the replacement PSU is also faulty or the CPU is dead...
Try starting the psu with a paper clip. Not a definitive answer but if it doesn't power on, you know it's toast.
It could be any number of things to the CPU, motherboard and memory to the PSU. My cousin's cousin's computer died as well. But in his case an RX 480 killed his motherboard. Not sure if it killed the CPU and RAM though. But the PSU was ok though. My guess its the board that is dead considering the PSU was a replacement one. I would try elcap's suggestion and try the paperclip method of starting up the PSU.
I would replace psu first followed by mb then cpu, I have never actual had cpu/mb out right die though, knock on wood Psu imo is easier thing to test first, everthing else require disassembly, which i dont like do it , it why i never took apparnt my old pc it just sitting in case with psu and gpu/hdd
This is basically the point that I'm at, Ive replaced the PSU, still dead, I've replaced the motherboard, still dead, I've tested the RAM in my current PC, that's fine, I've replaced the GPU with a known working GTX 780Ti. The only thing I can think of is that the replacement PSU is also dead, or the CPU is toast. I guess my question now is what are symptoms of a dead CPU? I'll test a 3rd PSU this weekend.
Does the computer even turn on when you hit the power button? One sign of a dead cpu is the computer will turn on but no video will be displayed.
Reset the CMOS. I suggest unplugging it from the wall, removing the CMOS battery and leaving it overnight to be sure. Next unplug everything from the motherboard and leave only one memory stick in and the gfx card. Try a different memory stick if needed. If still no joy, remove the memory and gfx card so the only thing left plugged in is the CPU. See if it powers up and stays powered up.
if the cpu is dead pc wont power on or i would assume it wont never actual had dead cpu, THen again I would think it would be the same for dead mb and dead psu
Never had / seen a case of a dead CPU either Got conductive thermal paste on the pins of an old Celeron CPU years ago, PC powered up for a few seconds then died, took the CPU out, big black burn marks on the bottom of the CPU Gave the board and chip to someone, they reported back a few days later that the board was indeed dead, but the CPU was fine
the psu is usually the first thing to fail other than hardrives or fans, and gtx 580 sli with an oced 2600k isn't exactly a light load to run for 5 years. even on a 1000 watt psu unlikely to be the cpu unless you were running 1.7volts at 80c and even then it would most likely degrade rather than completely failing.
Well, after three power supplies, two motherboards, some different RAM and another GPU I'm going to declare this CPU dead. Thinking maybe when the first power supply blew it took the CPU with it, will keep my eye out for a second hand one, not in any rush so we'll see what turns up. Am I right in thinking the i7 3770k is the same socket?
I don't believe the P68 boards got the ivy bridge updated BIOS. 2600k's are much cheaper second hand the 3770k's anyways.
Some, if not most P67 and Z68 motherboards will support with BIOS updates. Currently running a Asus Z68 Pro Gen 3 and PC at left both with Ivy Bridge CPU's. Both boards support pcie3 and usb3.
Well just to update this, having tried a 3rd known working power supply from my main PC, I'm declaring this CPU to be toast. So far it's had, New Motherboard, a GTX 780Ti, RAM from my current PC and three power supplies. I'll keep a look out for another 2600K but they still seem quite pricey.
