Hi. I love tech support guy for all the free help which it's generous members supply! Thank you all!

So here is my situation: I have just purchased all these components and assembled them into a full desktop computer (Which we will call Computer A):

• Biostar A770 A2+ Motherboard
• AMD 6400+ Windsor Processor
• RaidMax 420W Power Supply
• ZOTAC nVidia GeForce 9500GT Video Card
• Windows Vista Home Premium 64 Bit
• Western Digital Caviar 320GB SATA Hard Drive @ 3.0Gb/s

And since there is no VGA output on the motherboard, I used DVI-to-VGA adapter on my video card and plugged my monitor into that. When I turn on the computer, the lights and fans come on, I can hear the hard drive spinning, but on the monitor, it reads "No Signal." This struck me as odd, so I took out the hard drive and put it into (what I will call computer B, which worked without any motherboard drivers on the clean Hard Drive), installed Vista onto it, and the drivers for the video card. The monitor on Computer B also plugged into the video card/adapter and it worked fine before I even put the video card drivers on it. I thought doing these installations would fix the problem, so I just put my Vista and video-card-driver loaded hard drive into Computer A, but there was still a "no signal" on the monitor. I have run tests to confirm that the monitor is not the cause of the problem, neither is it's cable.

I do not know what is causing the problem, and I really would like some help. Thanks to everybody who even replies!

Weres the ran in that spec! lol o.j
Although it could possibly the ram thats the problem. Try the ram from computer b in computer a and test that...

Thanks for the reply!

Yeah, sorry. I have 4GB (2x2GB) Kingston 240-Pin DDR2 SDRAM 800 RAM. The RAM from the other motherboard does not seem to fix the problem. Do you have another idea?

Sounds like you have a shot motherboard. Mine did the same thing when I first bought it, sent it back, they couldn't igure out what was wrong (it didn't beep and the rest of myt parts are fine) and they replaced it...one thing, just try it bareboned (MB, RAM, CPU, Power-Supply and if there's no onboard video the geforce) if that does the same thing I'd say motherboard. Although if you have computer B, try using the power supply with computer B (even if it's just to rule it out).

Okay, thanks. I'll try the power supply. Still taking more suggestions!

The power supply swap did not fix the problem either. I am sort of at a loss of what I should do now. Please help!

My money is on the PCI-E x16 slot. Do you have an old PCI video card you can try?
