hp mini 2133 wont boot up

[priy]

I’ve been trying to turn on the computer but I only can see the blue power light and just the fan is working, but sometimes the computer just power on and I can work whit it all day, but if I shut down the computer and I try to turn it on the next day this is dead again.
Someone could tell me what the problem is with this computer?

is bios problem?

how to fix it

it looks like a SMPS problem or Loose contact of Hard disk or RAM...

remove and insert the RAM again and check the cables of harddisk......... if it persists then its SMPS problem........
