I have just done a major upgrade on my PC.
Part 1:
It started with my xp2200+, abit AT7 et al being transferred from a std case to a new thermaltake vm3000a skull case(with thermaltake butterfly PSU).
When I tried to boot, no display would come up on PC, monitor just said no input signal. After checking everything and trying a diff monitor cable, still nothing would happen.
Part 2:
I was due for an upgrade so I bought a AMD 64 3000+, Asus K8V mobo, MSI 5900 and 1 gig 3200 corsair ram(but still keeping my 200gig caviar drive, samsung dvd rom and plextor cd writer).
After building everything into the new case, the same thing happened, the monitor would not recognise a signal from the PC. I tried a diff monitor, and ide cables and even transplanted everything into my old case(but with the new PSU) but still no joy.
I know the hard drive is ok as I have tried it in a different PC.
any ideas as I cannot think of anything else it could be, and it's driving me nuts.
