My pc wont boot or start, i turn the power on and the fans spin and the HDD and power indicator lights are NOT on. the screen is blank and there is no sign that the computer is doing anything.
I replaced the power supply from 300watts to 450. Before that ...it would not come on at all...but since the change, only the fans are working.
Unplug all drive cables, backwards P-IDE can cause this issue.
If this doesn't help remove the video card if possible
If the motherboard is alive you should get a video beep.
If you don't hear anything remove the ram, you should get a memory beep. If you don't get a memory beep it's either the motherboard or CPU.
You could try to clear the CMOS and if the system has a backup BIOS review the manual to boot with the emergency BIOS.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

remove the two rear screws and remove all the cards attached to the main board
unplug all the cables that connect from the drives to the board.
power on the unit
if the unit powers up, install one of the cards you removed and complete step 3
if the system does not power up, the last card or device activated will be your culprit and will need to be replaced or left out.
if you find that your system will not show a bios splash screen with all the other components removed, then you are looking at either a video, or power supply failure. Listen to your system for spinning fans and hdd activity. touch the hdd if you cant hear it when you power up the system, paying close attention to when the drive activates. It should activate almost immediatley, pause, and then run for a short boot period. if nothing, then if may be your power supply. you will not be able to see any lights at all, no light on the motherboard, drives, or power LED is the best indicator of a shot power supply
"I have M305D S4830 laptop. I put it to sleep in the night. In the
morning when i tried to turn it on, it wouldnt start. The light on the
switch turns on and it charges the battery fine, but no HDD activity(but
it does spin up and stay), no screen, nothing. The fan turns on and
then turns off in 1 sec and then just the power indicator lights stay
on... i also checked cmos battery, removed it and put it back.its
voltage is also fine..."
Hello PPL! Maybe this WILL HELP you! I HAD absolutely the same problem >> 3 months of god **** stress, didn't find any solution, till one day i found on my Recovery CDs one note!! >> It sounds like: "BEFORE pressing power button, HOLD 'C' button and while Holding 'C' button push POWER Button ONCE!! to start Laptop, KEEP Holding 'C' button!!! untill appears TOSHIBA screen!" then release 'C'. After that, it will appear "Operating System not Found">>then just do a restart by pushing Power Button and Start again! For me, It Worked!! and i'm god **** happy now)...let me know if it Helped you, Good Luck!
Remove the hdd cover from the bottom and make sure it is completely seated and connected. If the hdd is properly installed and it still will not boot, try entering the CMOS Setup. If you can enter setup you most likely have a bad hdd. If you can't you need to take or send the pc to a repair shop.
Hi, my name is ArmyMason, hate to tell you this, but it sounds as if you have a bad Processor. Did you recently experience a bad storm with lightning? Was their a lot of dust on the fan? Lightning could have struck the computer and killed the processor or excessive overheating of the processor could have also been the case. If it was a lightning strike I would contact the insurance agency and have them replace your computer. Reason I think its the processor is because you don't recieve any post and the fan spins for a second and then shuts off.
