Man theirs a lot that can cause this issue, First Remove the battery and try powering it with just the Power cable, if this works great you need a new/used battery. Dose it make any "beeps"? Next try to Re-Seat the memory, and remove and Drives that you can. If none of these work it sounds like a bad motherboard.

Move your computer to different postions and see if the frequency of the problem changes. Take your computer to a wireless internet cafe and see what happens as you move around the cafe. If your computer works at the cafe, your wireless router may be defective.
My P28 bought off ebay did the same so i removed the ram cards and using a artist fine paintbrush brushed wd40(or q20 or any lubricant of this type)into the card slots onto the pins and replaced the memory.Next i removed the cpu cover and then 4 screws holding the cpu heatsink down and cleaned off the heatsink paste from the cpu and heatsink then replaced it with fresh paste and that seems to have worked and solved my problem.Out of intrest the paste was hard and tacky .
