Weird behavior on cold boot

[alfiesty]

I am having a strange problem. When I cold boot everything is normal until I log in to KDE. At that time I get lots of small boxes on a black screen with many colored ( Hey, I'm American, no u) vertical lines in them. At that point the computer responds to nothing but shut down. ctl-alt- f1 for another terminal or ctl-alt-del for shutdown don't work. After the computer shuts down, boot back up and everything is normal!

Re: Weird behavior on cold boot

ur cpu went to hot one day but didnt shut down so the smal nanomether lines of the core dilatedand now it needs to warm up so the electrons flow trought the cpu correctly
u should check if u dont have L1 L2 cache errors

this usually happens whit athlon 64 and notebooks

it hapend to me too when i used my single core athlon 64
i dont know which progs under linux could give u the answers
u should google for some overcloking progs whit temperature checs

prime95 is a math program that calculates merseene numbers (really huge calculation n numbers)
this would be the best choice to check fpu mem n cpu
