pc wont boot

[focus_water]

i have just built a computer and when i turn the computer on it will start to load and just befor it gets to the screen with winxp on it a blue screen will quickly come up and then the computer will restart.
i can load cd's and when i put the linux cd and load knoppix it will come up fine but the mouse jumps around then screen and clicks on everthing with out me touching it.
when i change the memory card and put in another one and turn the computer on the power light will flash very fast and nothing will happen unless i put in the one i got with the motherboard.

i dont know what is wrong with it. i think it couldnt have a virus in the motherboard somewhere.

is this a newly bought hardware? i reckon this is a memory problem. ive seen things like this before. now since live linux cds only use memory the caching is just in the RAM processing aint much of a job going to the pagefile much. so it runs well. try checking your memory or the memory slot.

reset the cmos
all new installs with new hardware should reset cmos jumper
then go to bios and reset your stuff
then reboot
check wher you have memory stick or sticks
some boards are backwards 1 stick only may go on outside
check the psu you may need more power
