Need help building a computer

[lostatftcarson]

Ok, here we go. I'm trying to build my daughter a computer, nothing fancy, just something she can screw around on. By the way this is my first build. So I went and bought a cheapo case, an AMD Duron 1.6 Ghz CPU, Rosewill PC2100 ram, ASRock K7VT4A motherboard, a Mad Dog G-force MX 4000 graphics card with 128mb of DDR ram, and a Western Digital 40 Gig hard drive. Now the problem I'm having is every time I finish puting the damn thing together and hooked up, the Monitor doesn't pick anything up. I thought it was the AGP slot on the motherboard, because the videocard works fine in my computer, so I bought another motherboard. But I'm still having the same problem. The monitor is telling me there is no signal from the computer. Can anyone out there help?

The number one thing that every computer builder does wrong: (s)he closes the case up too soon Seriously though check that the memory and the videocard are properly seated in the slot

For reference sake, what computer do you have? (specs)

Powmax Case w/350w power supply
ASRock K7VT4A+
AMD Duron 1600 w/ 266FSB
Rosewill PC 2100 (256MB)
Mad Dog Predator Nvidia G-Force MX 4000 w/128Mb
Samsung 40Gb hard drive
Philips CD/RW

The computer that I'm running now:

Matsonic MS9307C+USB
Intel P4 2.53Ghz
PQI Power PC 2700 512Mb
100Gig hard drive (80Gig WD, 20Gig Samsung)
BFG Nvidia GForce FX 5200 w/256Mb
Lite-On DVD/RW

Re:

Helloooo,

Is the RAM in good shape? Sounds like a RAM issue...might be something else though. Try using a different brand...

 

[Cromewell]

does it beep at all when you turn it on (or is there no PC speaker)?

Could it be the mobo only supports say Single sided dimms and you've got a double sidded one? (or vice versa), i know some older mobos are real finicky with that
