Solve : Help with freeze ups.?

1.	Solve : Help with freeze ups.?
Answer» friend of my has a custom built SYSTEM and no specs are available at this time. All i know until i able to get down there and LOOK at it myself is the OS is UBUNTU. The puter is freezing up/ locking up during normal use... I thinking it may be a cooling/overheating problem since this is a custom built system... To eliminate this POSSIBILITY is there any download available to monitorand or check the temp for linux based systems? Something similar to Speedfan? TRY lm-sensors or CPUtemp.
