Working one minute then nothing!

[bilpo]

I have built a new computer, AsrockK7s8x, AMD 2500, 256 ram, 120gb HD , Nvidia Geforce4 MX 440 SE Video Card. Install XP. However,the system has given me loads of stress, and now, on occasions, will not boot.
Power comes on hd starts, then nothing. Blank screen,no bleeps and computer willnot switch off.

I thought it may be the graphics card so I bought a new one, seemed Ok for a while everything checked OK in device manager,all worked really sweet. Switched off, came back to it and nothing!!

I'm think AGP slot faulty, or video card is not compatable with this board, I could do with some advice,,Please!!

Checked all things mentioned, and on occasions everything is OK. Then, switch on, nothing on the screen at all, no bleeps, lights come on and wont turn off.

I'm thinking now it could be a dodgy power pack.

Thanks for your help
