Monitor on standby? Should i change voltage?

[tnet]

Hi

can anyone help me with something. I have just built a new pc and it worked fine for a while except i sometimes got an error message before it would boot saying 'Warning! Now system is in safe mode! Please resetting cpu or memory frequancy in the cmos setup' I could then press f1 to continue and windows loaded fine. However i then changed my case and when i put everything into the new case one of my graphics cards wouldnt work and now my monitor will not turn on or very very rarely, it just stays on standby and the pc stops booting even though the power is on. Can anyone help me with this? I wondered if raising the core voltage would solve this? its not something i have ever done, which would i need to change Vcore?

Maybe the graphics card problem is related to this, could it be a problem with the mobo which has caused both problems?

thanks very much any help

My system specs are:
intel p4 3.4ghz with HT (with thermaltake big typhoon fan heatsink)
Asus p5nd2sli mobo
2gb corsair ddr2 (4x 512mb)
nvidia 6800gt sli graphics card
40gb ide HD

Thanks

Tim

I am not an expert but I use to have a similar problem a few months ago with my PC and it turned out to be the PSU which was not powerfull enough (and your PC I think is quite a consumer with the SLI and Prescott cpu)
This could make the voltages go below the cpu/video card necesities and they would not work.

Sugestions:
Try unpluging HDD, DVD FDD - does it start? if so its more likely the PSU is not up to the job.
Maybe buy a new PSU but you sould wait for more opinions since I am not 100% sure about this.

thanks thats interesting, my PSU is actually an akasa 650w so i would have thought it was powerfull enough but i will wait and see what anyone else says. thanks
