My PC keeps restarting! Help!

Recently I changed my flat and moved to a new location. Transported my PC. It was a short travel and I was in the car. I can assure no major or fatal shakes were encountered during the transport.

Now, coming to topic. Connected my PC last night and booted it.
It kept on restarting on boot itself.

Let me give you exact details....

Switch on power button-->

PSU is on, fan moving
Cabinet fans moving
MOBO light is on
Initial POST code is 90

Within 3 sec. it changes code to 99 and restarts
In this duration power did not come to my KBD and Mouse (using Razor Cyclosa and they have a blue LED which obviously lights on if power is on)

My guess is
1>the PC is not getting enough power.
Its normal plug point. Should I try a high AMP power soket?

2>The CMOS battery is the culprit.
Any way to check?

3>The PSU itself is gone.
But is was working perfectly even two weeks back!

b/w no beeps were heard though in this whole time.

Any lead guys? I'm at a loss what to look for.
