im going out of my freaking mine here so any help would be greatly appreciated
i started rebuilding my pc a month ago, current specs are
Intel 3570k (stock cooler, no overclock)
8bg corsair vengeance RAM
GTX 260 GPU
2x 1tb Western Digital HDDS
120gb OCZ Agility 3 SSD
everything running at stock and has been for the past month with no problems. last month i started the rebuild and added the new motherboard, CPU, RAM and SSD. everything else been running for years with no problems but plan to upgrade over the next few months
ANYWAY... all been running fine, no problems, then this morning it wont POST. i have the GPU, CPU and DRAM LEDS all flashing in that order, none staying on constantly.
i initially tried removing all the items one by one but no joy. when i put the CPU back, it worked, i exited the BIOS then the same thing again.
after then disconnecting the everything and starting from scratch again it worked, tried it a few times and got into windows and all ok. then while in windows i put the pc back on its side gently (it was laying flat where i was woking on it) and the screen went black and back to no POST and all 3 LEDs flashing.
anyone have any ideas? i feel either the problem lies with the CPU or the Motherboard but dont understand why. also having real trouble finding info on the net about the LEDs flashing and not staying on constantly, even in the mobo manual its not mentioned. i really need to troubleshoot exactly what has failed before i contact Ebuyer about returning whichever part has failed
any help you guys can give would be greatly appreciated
i have issues with my z77 premium, where it occassionally refuses to start with my ram, a reboot, or pushing the mem-ok button makes it go away. I suspect that there are issues with accepting certain memory types. Bios updates could have resolved this, they have not so far for me.
Hmm, I have an Asus P8Z77 Deluxe and a 3770K, 16 GB of Corsair Vengeance 1866, and never had a problem - booted first time and every time .
I wonder if the CPU was seated properly, or maybe some intermittent short, since you say it works in one position (vertical) and not the other (horizontal). Or it could have been a loose DIMM or a loose connector too.
Anyway I'd run it as much as possible before your return policy expires and see if it happens again. The mobo should have come with a diagnostic utility so try that and see if everything passes. Then stress it a bit with Prime95 as well.
yeah it was really wierd, when i built it i had no problems what so ever. been running perfectly this past month. then installed gw2 yesterday and was playing with no problems, turned it off last night then as i say, refused to turn on this morning. i hoping it was something as simple as something not connected properly.
in the end i took it all apart, reconnected it all one by one and testing at each stage. when i got the BOIS up the 1st time i flashed it, and so far has been working fine again, just a bit worried to turn it off again lol.
the thing that was most annoying though was the POST LED's flashing GPU > CPU > RAM > GPU > CPU etc etc. made trying to work out what was wrong very difficult.
