My computer makes random frequent freezing episodes. These episodes are punctuated by a periodic "thinking"-type sound (like it's working), which comes up every 5 seconds or so and lasts about a second each time. The episode lasts about 30 seconds to a minute. Everything freezes, although usually only the page I have active (mainly Firefox) will show up as not responding on activity monitor. I have noticed that ocspd comes up on activity monitor right before the episodes. Sometimes ocspd will be not responding, although usually I can't see this because once the episode is over everything goes back to normal. WHAT IS WRONG? This has been going on for like a year and it's mainly just an inconvenience, but still. Oh, and Console flat-out doesn't work. When I open it up, it immediately stops responding and makes everything freeze for a bit. I don't know what is relevant information-wise, so I'm just going to paste the Hardware Overview: Model Name: MacBook Model Identifier: MacBook4,1 Processor Name: Intel Core 2 Duo Processor Speed: 2.1 GHz Number Of Processors: 1 Total Number Of Cores: 2 L2 Cache: 3 MB Memory: 1 GB Bus Speed: 800 MHz Boot ROM Version: MB41.00C1.B00 SMC Version (system): 1.31f0 Serial Number (system): 458502155HS Hardware UUID: AC4C6D1B-58DE-5B23-B879-F31F5915A850 Sudden Motion Sensor: State: Enabled As for Console crashing, I went into terminal and typed tail -f /var/log/system.log and got this: tail -Last login: Tue Dec 28 21:58:12 on console fX-X-macbook-2:~ X$ tail -f/var/log/system.log tail: illegal option -- / usage: tail [-F | -f | -r] [-b # | -c # | -n #] [file ...] X-X-macbook-2:~ jX$ tail -f /var/log/system.log Mar 4 23:09:47 X-X-macbook-2 Disk Utility: ********** Mar 4 23:09:47 X-X-macbook-2 Disk Utility: Disk Utility started.
