I have encountered a weird problem with my computer:
Sometimes it boots normally and sometimes gives a black screen and sometimes it restarts itself and sometimes there is an endless loop of restarts. When black screen comes you can do nothing and it's only black and you can only unplug the pc since the power button will not work.
I installed another hard drive and installed Ubuntu (now dualboot-system with windows) but I'm still having the problem.
I also changed the boot sequence in Bios options, otherwise bios settings are default.
I have read somewhere that when computer boots only sometimes it's usually broken RAM stick, so I tried different RAM sticks and different slots but it was all in vain. I also ran Memtest86+ with 6 passes and no errors, after this I noticed that computer boots normally after Memtest.
Now I'm suspecting it might be GPU problem but when it boots normally everything is absolutely fine so I dunno if it can be GPU either.
Now, I will have to run Memtest every time I want to start my computer, not a big deal really but it would be nice to get rid of this problem.
Can anyone help?
And the computer is this:
Fujitsu Siemens scenic p320 l915g
And the motherboard
And I don't think this has anything to do with software since the problems are the same on windows xp and on Ubuntu.
