Hi, I'm looking for help with my system which I have upgraded to in the summer. It was my first build and I learnt a huge amount from doing it, but I am definitely still a pc system noob! I bought all new parts for the system to hopefully ensure a trouble free setup, no such luck! The computer randomly crashes and I cannot find a cause or a solution for it! When the computer works it wors very well ans shows no sign of any problems, and then all of a sudden it will freeze, do nothing for a while and then shut down as if the plug has been pulled. Sometimes it will work for 4 or more hours with FSX, other games, movies or CAD working then freeze, other times I don't even get to the windows log on screen before it does it.

 

I have tried a different hard drive, different RAM, and downgraded from windows 7 ultimate to a complete vanilla install of windows 7 professional with no effect. I heard it can be a driver issue but in my device manager everything appears OK. I also heard it could be a conflict between the internal and external GPU so I turned off the onboard GPU and that didn't help. I've also heard that it could be a PSU problem but I would expect it to turn off straight away rather than freeze first, but that comes from almost no experience at all so I could be wrong!

 

My spec is:

 

Intel i5 3570k Ivybridge 3.4Ghz (3.8Ghz with turbo boost on MoBo, also tried turning off, no difference)

Gigabyte GA-Z77-D3H MoBo

8GB DDR3 Corsair Vengeance RAM

1TB Western Digital Caviar Black HDD

550W OCZ ZT Series 80 Plus PSU

Arctic Cooling Freezer 13 Pro CPU Cooler

Windows 7 Professional

 

I'm all out of ideas to try so hopefully the many years of experience on here may come up with a solution. Apologies if this has been posted about before or if it is a simple fix I am unaware of (and this huge essay to read!).

 

Thanks in advance!

Have you the last bios ?

The Z77 boards have some issiues with random shutowns ( all vendors).

usb3 and sata drivers

They often work with Sandy bridge CPUs but can be problems with Ivy Bridge.

 

I have no problems when running à 2700k but when swap to the 3770K i get some

Random shutowns , solwed with bios uppdate

Apologies for it taking me so long Hasse but you were absolutely correct, after many frustrating hours and a fair wedge of money spent trying to fix my problem it was a simple, free, 5 minute BIOS update that solved the issue and I haven't had a single problem since. Thanks very much for your advice, sorry again it took so long to post my gratitude!

No Problem, the best thing is that your new PC works

and thanks for the kind words
