The PC does not start.Only it beeps and a red light blinks,also fen is not working.


here are some of the basic codes, depending on which BIOS you have...

Also you do not indicate which fan? I would guess you mean the main Power Supply (PS)? In which case it could just be you need to replace the PS.

Here is a link to some other codes as well...

Memory card isshowing corrupt


That means that memory card is faulty and you must replace the memory card.

Test the memory card on a computer using a card reader and test a different card inside the phone.

If the phone returns same error with all memory cards, then the phone memory card slot is faulty, otherwise just replace memory card.

My computer cant start up and is making a beeping noise


Most likely a ram problem. Sometimes reseating the memory will fix the problem.

Remove and reseat the RAM On most notebook PCs, removing and reinserting the memory is a simple step and does not require advanced technical knowledge of the computer. HP recommends reseating the memory module before arranging for warranty service repair. If you are not confident following the steps for removing and replacing the memory module in this document, contact an HP support specialist for assistance.
NOTE: If someone other than HP installs or upgrades the RAM, any damage caused by the RAM and/or by the person when trying to install or upgrade the RAM is excluded from coverage under the product warranty. The customer assumes all risk and liability for damages for any such installation or upgrade.Some HP notebooks may have a secondary memory module located under the keyboard. For removal and replacement instructions pertaining to the second memory module contact an HP support specialist for assistance. WARNING: This product contains components that are easily damaged by Electrostatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, set the notebook on a grounded surface that dissipates any static charge, and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC. Use the following steps to remove and replace the memory modules. These steps should be repeated for each memory module installed in your notebook. Step 1 - Remove the battery
  1. Slide and hold the battery release latch to the unlock position.
  2. Use your finger to lift the battery up and out.
Step 2 - Remove the memory module
  1. Locate the memory module cover on the bottom of the notebook.
  2. Remove the screw that covers the memory module.
  3. Use your finger or a flat head screw driver to lift the inside edge of the memory module and remove it.
    NOTE: When handling a memory board, use care to prevent touching the memory chips on the board. Touching the memory chips could damage or destroy the memory.
  4. Push both tabs outward simultaneously to release the memory module.
  5. Grasp the memory module by the edges and pull gently to remove it.
  6. After removing one module, replace the memory expansion cover and then replace the screw.
Step 3 - Reseat the memory module
  1. Locate the memory module cover on the bottom of the notebook.
  2. Remove the screw that covers the memory module.
  3. Locate the alignment slot on the memory module and align it to the empty board receptacle.
  4. Grasp the memory module by the edge and push gently to install it.
    NOTE: When handling a memory board, use care to prevent touching the memory chips on the board. Touching the memory chips could damage or destroy the memory.
  5. Press the expansion memory board down to latch the tabs.
  6. After replacing the module, replace the memory expansion cover and then replace the screw.
After the memory is reseated, connect the AC adapter and turn on the notebook.
