Big problem please help

[Math]

hey guys i have a strange hardware problem and need assistance.


when i start my system up some times it wont boot properly it just starts up then powers down then restarts over and over. it will do this until i open the side of the case and jiggle the graphics card about. then it will boot normaly some times my sound card wont work when this happens.. but a restart normaly fixes this.. i do have a water block on my graphics card and it bends the card ever so slightly. not enough for me to be concerned about before but this is very strange.

any one have any suggestions or tips?


Thanks in advance!

nope its not over clocked.. it was starting to get laggy due to bad uninstalls and i formated it


after the format it was very slow and laggy .. plus my down load speeds were awful.. so i tryed a reformat to see if that helped. but now i cant even do that it locks up ...or powers down without reason.

Spec is P4 lga775 radeon x850 pci 2g corsair ram 250 g deathstar HD and a Aerocool 550w power supply

this is driveing me crazy now
