Hello all,

Few months ago I built a system with the following component:

E6550 Core2Duo
2x1GB G-skill-6400
Asus P5B-VM SE - Intel G965 (Core 2 Duo/Extreme) PCI-E Socket 775 Motherboard
Seagate Barracuda 7200.10 320GB 7200 RPM $85.00
ATI HD 2400 Pro Video Card

with an InWin C583T (Black ) 350W w/ stock power supply that came with it..
In the beginning there was no problem at all but as time went
I started having booting problems..

When I pressed the power switch it boots up but turns off in few seconds then few seconds later it turns back on by itself. Once it powers up there is no problem ..but at first it only turned off once then back on and boot into windows, but as time went it started happening more frequently and now I have to press the power switch many times (powers up , shuts down power on, shuts down and after many times it turns back on by itself and boots into windows.. )Could this be a power supply problem while 350W is not enough to power up all these components
or other components might have problems?? Please advise me asap ..Thank you..^^

Your PSU certainly comes in to question. You could upgrade with a more powerful unit and see if the problem persists. There was some earlier discussions on the ASUS boards regarding the symptom, but I'm not sure this pertains to what you are experiencing.
