overheating and beeps

[Caterpillar]

R500 overheats even if some months ago I replaced the fan and putted a new thermal grease. BIOS version is the lastest one, what can cause this problem?
When the R500 is powered on for the first time in a day, it plays 1 beep 3 beeps 3 beeps 1 beep while the screen is black. To be able to use the computer you must power it off and power on again.

The 1-3-3-1 beep indicates bad, or poorly seated, RAM.
Normally you apply thermal paste in the size of about a rice corn, and spread that out evenly.
If you add more (or less) overheating can be the result.
Lift up the keyboard before you start, to check that the fan indeed spins if you boot up.

The overheat problem happened even before I putted my hands onto the heatsink/fan....
