When I turn on my packard bell ixtreme 6052 nothing appears yet it does see computer but does not even go to bios and harddrive read light remains on and harddrive is constantly ticking like it's desperately trying to find something before eventually the hard drive gives up computer power light remains on and at that point we have to flick off switch as nothing happens all the while nothing shows up on screen.

This could be lots of things (bad HD, bad Mother board, bad RAM,etc...) first you need to narrow down the possible cause, open the computer, take out every thing that can be unplugged (I MEAN EVERYTHING) RAM, PCI cards, VIDEO cards, all storages HD, CD ROM, etc... just leave the CPU and power supply plugged in, than power up the computer and listen for BEEP's if you hear a series of BEEP's this means the CPU, power supply and mother board are GOOD, than (with power OFF each time) re-install the components you taken out (ONE at a time) to see which device causes the system crash... I've seen a modem card causing a system mall function once rediculous but true...

Good luck!
