My dads emachine w2040 It wouldnt power up at all one day. I replaced the power supply with the recomended upgrade from emachine. Now it powers up just fine, the fans are flowing, the cd drive opens and closes, but the HD lights up one time then thats it. Nothing is coming over the monitor nothing is happening as far as the boot up process. I suspect that lightning or power surge has damaged the psu but I dont think the MoBo was damaged. What should I check? Should I try the restore disk? Help?
