hi all.. i have just brought a brand new pc for someone off a company out of micro-mart, i set it all up fine, installed windows 98se fine but then noticed that if you leave it alone and dont touch anything for about 15 mins and then move the mouse then the whle pc restarts, power just goes straigt away and starts to load up again..

any ideas on what can be causing this problem? shorly it cant be a software fault?

cheers all
