Computer Wont Boot!!! HELP ME!!

[SpliT71]

Computer has ran fine forever, since i built it last july, no hiccups. I start TF2 and get past the valve screen, about to load the main screen for TF2, but before it gets there, i hear a ding like an error, but i have a blank screen inbetween loading. Now, i tried CTRL + ALT + DEL to no avail. So i just naturally pressed the power button. Now the computer wont boot. It turns on, everything sounds like it's working, but no go. Doesn't show anything on the screen, monitor light just flashes.

Any ideas?!

Try:
1. Checking cables to see if they are loose.
2. reseat all applicable parts, ram, graphics card, etc.
3. pull any unnecessary parts and try to POST.

I'm sure others will have more.

Did all those

Got access to a spare Video Card and PSU you can try? If it's not those, I'd then alternatively try and pull sticks of ram and then look at the cpu or MB.

Figured it out, i thought i had an idea from the start. It was the PSU. Picked up an antec truepower trio and it works.
