The hard disk may have died. Check the BIOS and check the hard disk setting, if it appears OK then boot up with a DOS floppy startup boot disk, and select boot up without CD-ROM support, then type fdisk, answer Y to large disk support, select 4 to Display partition information.
If you see all your disk partition the most likely your hard disk is OK.
Most likely you operating system is damaged/corrupted and you will need to reinstall your operating system and drivers for all your devices.

My hp a345c will not turn on. It has a flashing


So basically you cannot get the pc to POST. Meaning you have just a black screen when you power on the pc, right?

First off, did you attempt to update BIOS before this happened. 90% of the time this is caused by a corrupt bios.

If you are the victim of a bad BIOS flash, don't freak there are some options. First off, if the computer (or motherboard) is still under warranty the Computer (or motherboard) can be sent to the Vendor for a BIOS reprogramming.
If you are a DIY PCbuilder and the warranty is expired you can take out the bios chip andsent it someone who reprograms BIOS chips or you can buy a brand newchip form them. I will show you my people.

For non-BIOS issues:

If you did not try to update BIOS before the problem started then try these troubleshooting steps.

1.Full power down. Unplug the power cord from the Power supply. Then holddown the pc power button (this discharges any residual power in thecapacitors).

2. Open the case and reseat the graphics card, hard drive, and RAM.

3.Take out one of the RAM sticks if there is 2 or more. Swap the RAMsticks in different RAM slots. Try one stick at a time to see if youcan get the PC to boot. If this works, then the remaining ram sticksare damaged.

4. Set the Cmos jumper to clear. Power up the pc.Power down the PC. Set the Cmos jumper back to normal position, powerup the PC.

5. Unplug and replug all the power supply cables.

6.Check the powersupply function. Either by a powersupply voltage checker(20-25 dollars at local PC shop), get the supply tested at a PC shop(usually a free service), put the powersupply in a different pc, or trya different powersupply in the problem computer.

Ifthe Powersupply checks out ok, then you will have to do a process ofelimination to find out what part or parts are the culprit of theNo-Boot.

Start by pulling all the ram sticks if you have not already. This is the easiest components to check and usually a culprit.

Takeout one of the RAM sticks if there is 2 or more. Swap the RAM sticks indifferent RAM slots. Try one stick at a time to see if you can get thePC to boot. If this works, then the remaining ram sticks are damaged.

If it is not the RAM, you have to continue removing items such as sound cards, un-plugging hard drives and optical drives,other PCI cards. Do this one at a time until you find the culprit.

Power shuts down while booting


most likely, the PS is saving itself from thermal meltdown. 1.) verify that the PS cooling fan is spinning. If it is, continue to step 2. If not spinning or spinning slowly, open PS and thoroughly clean using compressed air outside. 2.) remove PS connectors to mainboard and re-insert them. Repeat this 3 times to "wipe" the contacts to clean metal.
