This is usually loose RAM on an HP, or in some cases a failed module. Remove the battery, the main cover below the hard drive cover and reseat the SODIMM module/s. If it persists, they're bad and need to be replaced.

If neither of these help, the motherboard is dead - common on these "low cost" HP laptops.
