Graphics/Motherboard Problem

[andrewhillier]

I have an HP Pavillion a6000 desktop, which, of course, has an onboard graphics card. 18 months ago, I put in an EVGA geforce 9500 video card and put in a TOPOWER TOP-550PCM 550W ATX / BTX Power Supply, which, since I'm not hugely computer savvy, my roommate (who I no longer live with) installed.

Two days ago, my computer gave me a blue screen, restarted itself, then froze on the start-up. When I hard reset it, nothing came up on the monitor. I figured that my video card died, but I still felt it was strange that NOTHING came up on the monitor, not even a start up screen. I bought a new video card, installed it into the pci slot, and plugged in the monitor - same problem: nothing (and I mean nothing) came up.

I took the the new video card out, and plugged the monitor into the onboard video card - still nothing. I took the battery out to clear the CMOS and restore factory BIOS settings - still nothing. I don't really know where to go from here.

When I start up the computer, all fans are running and I don't get any sort of beep code. Because there is power going to the fans, I don't think it can be a power supply issue, can it? When I had the new video card in, the fan was running, but obviously it wasn't getting picture to the monitor.

I'm pretty much out of ideas. I would really appreciated some help on this. Note: everything on the computer is stock, the exceptions of the power supply and graphics card.

Thanks in advance,

Andrew

The mains things to look at when you aren't getting display is video card, memory, power supply, and motherboard. Since you get the same thing with the onboard that means your video card isn't causing it. In my experience when a power supply fails the fans and LEDs still come on. It can definitely be the power supply. Try the old power supply if you still have it. Most people have multiple sticks of memory and it is unlikely for them all to fail so trying them one at a time should count that out. If you get the same thing with all of your sticks of memory and the other power supply then your motherboard has most likely failed.

If you have the same problem when you hook up the old power supply, I would say your motherboard died.
This is not a video card problem.
