This is usually a heat or overtaxed power supply issue. I don't get a clear picture of the machine. Is it some HP or other name?
i have a intell mother board dg965wh with chipset g965 video card e-GeForce 7300 running xp media center with sp2
when i reboot the monitor will not come on unless i turn it off and wait approx 15 min. i have tried a different monitor , replaced the video card , reflashed the bios, reflashed the mother board all to no avail. can anyone tell me where to look for this problem it is driving me crazy. temp of the computer runs at 85 this is the same as it was before ths problem occured
