Computer locks up randomly

Comment:

My power supply recently went downhill on my laptop.... For the last few months my computer has been getting very warm on the underside. I have been putting it off and one day I came home and my computer was off. I tried to turn it on and i had no power and couldnt charge it either. I looked into it and found that my power supply on my motherboard was bad. I ordered a whole new motherboard and installed it... the computer starts up but will now randomly lock up whether it is booting up or after i have used it for a lil while. Also when i do get it booted up sometimes it will give me that there is a power surge at one of my USB ports.... Any Help???
