Help needed - my shuttle seems to have died

[schrickvr6]

I've got a shuttle sk41(i think,its the via one with onboard gfx and no agp slot anyway)

To start a few weeks ago i noticed that red wasn't displaying properly on my monitor then all of a sudden no display at all,everything seemed to power up except the gfx so i tried an old 2mb pci gfx card and it posted first time,i went into bios looking to disable the onboard gfx but couldn't find the option so i reduced the shared video memory to 4mb,f10'd,restarted and it was just the same as before,everything seems to power up but no display.I've tried everthing i can think of(different ram,cpu etc) and am now going to try the mobo outside the case in case anything is shorting,i'm also going to try another psu.

Has anyone experienced anything like this before?any advice would be very much appreciated

Before anyone suggests rma this was an ebay purchase how much would a borked shuttle be worth?If its not much i think its going to become a very expensive rad-box

Why oh why is it always the last thing you try,turns out the psu can't be giving enough juice,the onboard gfx are fine,strange how the psu effected the gfx colours and then stopped it working altogether,time to order a 250w
