Synthesthesia Posted October 29, 2011 Share Posted October 29, 2011 I don't think what I'm having is kernel panics, since those have an error message? Everything works perfectly, sound, internet, graphics card shows up correct etc etc. But I get a seemingly random freeze which leads to either a black screen, a grey screen with grey lines, or I've also had a grey screen with green lines. No apple logo or error message. Anyone got any ideas? Here's my hardware: Intel Core i7 2600k 3.4GHz Socket 1155 Corsair Vengeance 16GB (4x4GB) DDR3 1600Mhz OCZ 60GB Agility 3 SSD - 2.5" SATA-III PowerColor HD 6870 1GB Gigabyte Z68X-UD3-B3 Thanks Link to comment https://www.insanelymac.com/forum/topic/271242-random-freeze-screen-every-so-often/ Share on other sites More sharing options...
Synthesthesia Posted October 29, 2011 Author Share Posted October 29, 2011 I don't think it'd a hardware issue if I got a geek bench score of 12699 would it be? So annoying because it works perfectly but I just get these random freezes Link to comment https://www.insanelymac.com/forum/topic/271242-random-freeze-screen-every-so-often/#findComment-1765828 Share on other sites More sharing options...

So annoying because it works perfectly but I just get these random freezes Well this sounds like hardware to me. I would start by downloading the memtest for mac and running several passes. Any memory error is cause to replace the offending stick. This test is run at the single user mode (boot with the -s argument and start memtest at the character base command prompt). Then if the memory passes without error, the SSD is the next one to swap out. For this, run a standard hard disk for a lengthy period to see if the problem persists. If you still have the problem, swap video cards, then PSU's. If it is not a sub system, then it is the motherboard. I have had ASUS and Gigabyte motherboards go sour and act up also an OCZ Vertex 3 SSDcause problems such as you describe. Isolating the problem is time consuming. neil Link to comment https://www.insanelymac.com/forum/topic/271242-random-freeze-screen-every-so-often/#findComment-1765894 Share on other sites More sharing options...
Gringo Vermelho Posted October 30, 2011 Share Posted October 30, 2011 Run Console.app, look at kernel.log and system.log for clues. Link to comment https://www.insanelymac.com/forum/topic/271242-random-freeze-screen-every-so-often/#findComment-1765911 Share on other sites More sharing options...
