I just got a new case today and after switching the cases I tried to power up in my new case and it won't post. I can hear and see everything turning on, all the fans, lights, etc. but the monitor is still blank. I took the mobo out, unplugged every led except for the PWR one, I put my video card, cpu +hsf (after taking the hsf and reconnecting it), floppy drive, hdd with windows xp, ram, and placed them on top of a phone book and powered them all up. I tried to boot up the computer, and I can hear and see everything starting up, the fans are all moving, the mobo's little light is on but nothing appears on the screen. I've tried 2 different video cards and 2 different monitors but I can't get it to post. I tried resetting the CMOS but it didn't do anything, I dunno wtf could be wrong i've tried everything I can think of. Any help would be greatly appreciated.
My comp is:
AMD 2000+ with Volcano 7+ cooling it
a WD 120gb and WD 20gb
zipcd 8x burner
512ddr pc2700 ram
Giga-byte GA-7VRXP
MSI GF4 ti4400 vivo
300W power supply
SB live value
blinky
P.S. I posted already in General Tech help, then I noticed that my problem fit in this category.
