The new build: Gigabyte GA M57SLI-S4 SKT AM2 AMD Athlon 64 X2 4400+ Socket AM2 Innovision 3D 8500GT 512MB DDR2 VGA DVI PCI-E 2 x Crucial 2GB kit (1GBx2) DDR2 PC2-5300 PSU: Extra Value Gold 750W Silent PSU - 12cm Fan, 20+4pin, 2x SATA, 1x PCI-E Pioneer BluRay DVDRW (2 months old) 500 gig Seagate IDE hdd (6 months old) The first problem was that the original PSU was doa. I tried an older 350w psu to see if the build worked and that would not boot the monitor. No surprise really, I thought, and awaited the delivery of replacement. This arrived yesterday, installed it, system posts etc, but monitor would not boot. I have tried this with both a tft and a crt, both of which I know work. I have changed cables. I have used a motherboard tester card, which informs me that all is well. The fan spins on the graphics card, but am I right in thinking the card could be faulty? Or am I being spectacularly dim, and have missed something basic? Any help and suggestions would be, as usual, very gratefully received! Cheers all!
