This is either something that got in or is dust buildup. Your system should be as clean as possible internally. Lets work though some of the things I saw in your question: I've just installed TGPro (trial at this point) and it looks like my laptop's temperature is usually 3-4✬ above the "average" (as TGPro says on its interface).Ī friend had a similar problem, went to a technician and was advised that they had to replace the GPU "and a few ICs on the board".Īny suggestions on what I should/could do next?Ĭomplete system crashes are some of the hardest problems to isolate as so many things could be the cause. The only difference between today and the past 2-3 days when I could work very peacefully was that I had the browser on (first it was Firefox, then when it started crashing, Safari) when the system crashes, and I was doing quite extensive work on Facebook. There's no beeping anymore, but the crashes now are quite frequent (around 10 times the last 2 hours), and the random/interference lines came out 1 time (out of about 10 crashes). Just a few hours ago, however, my laptop started freezing again, and restarting itself. Then, for the next 2-3 days it was very peaceful - I could work without crashes, and I would be able to properly shut down at the end of the day. Memtest reported there was no problem with the RAMs. I booted as a single-user (command-s while starting up), and ran the memtest for a bit more than 6 hours (17 repeats). So I thought to do a proper test - what I did was the memtest 4.2.2. When I did a system profiling ("About This Mac") I saw that the Memory slots and sticks were reported as "OK" (2GB + 2GB) - but this has always been the case, even before I took the RAMs out. This was the first time I could work for a whole length of time, and I could properly shut it down again when I finish working.īecause I needed the whole 4GB RAM to work, I put the other stick in again.
So I restarted it, and managed to run with 1 RAM stick for quite a while, monitoring the usage with Memory Clean. When I turned it on, it worked for 2 minutes before it started freezing again, with the random lines on the screen, but no beeps. Took off both RAMs at first, let it do the 1-beeps for a minute, then put 1 RAM back. I also cleaned it (it wasn't visibly dirty apart from a ø2mm of whitish powdery stuff between the RAM sticks and the battery cable). took off the battery cable before fiddling with the RAM sticks. I opened it following the instructions carefully, e.g. What I did after this was opening up my laptop. It wouldn't restart itself - I would have to hold the power button down for a while to get the 3-beeps to stop. Around this time, just after my laptop started to freeze, the screen would be covered in random (interference) lines before the whole system would shut down and go to the 3-beeps. There seemed to be no connection between my RAM usage and the crashes. Next, I installed Memory Clean v4.8 (FIPLAB) and tried to control my memory usage through it.

This didn't seem to help with the crashing (although it did get rid of clutter in my system, and I now have much more free space in my internal HDD).
Memory clean fiplab install#
So, what I did was, firstly, to clean install Mountain Lion (as I've been planning to do it for some time). I gathered (googled) that this was potentially a RAM problem. This time, however, it was followed by the 3-beeps, and it didn't restart itself. But I eventually planned a clean install of Mountain Lion, because I thought perhaps my 10.7.5 was too outdated already.īefore I got to install Mountain Lion, though, a few weeks ago at one critical point (I was finishing up a Keynote doc with lots of images), my laptop froze again.
Memory clean fiplab mac os x#
By the way, all along, the internal HDD was fine (checked with Disk Utility).Īt this point, I was still trying to keep Mac OS X 10.7.5 (because of some softwares that might've not worked well if I had upgraded). This was why I started carefully backing up (by cloning and with time machine).
Using Firefox worked for a while, until I started getting the same crashes again.
So I stopped using Safari and installed Firefox. The whole OS would freeze, then restart itself. When they started happening, the crashes usually seemed to be related to Safari. I'll try to describe the problem(s) and what I've done as clearly as possible (and, I've been troubleshooting for some time, so I hope you wouldn't find it a problem that my description below is quite long). I'm still having the crashes, though, so I need to hear any suggestions on what this might be. I've been troubleshooting and trying to solve it since then, in between deadlines. Hi - I've been experiencing frequent crashes since about a year ago.
