Graphics/Motherboard Problem

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

It can be anything! But if you get no beep codes and no post it tends to be CPU / Mobo related

Having said that PSU can give some real weird results due to under voltage / current

Best to try a new PSU first unless there are better suggestions

Did you try reseating the RAM, vid card and any other plug in?

fans spinning doesn't rule out a bad or weak power supply... If you can get your hands on one to swap in, that would be your best bet....

I dont know if you can simply switch over to the onboard graphics.. There is usually a bios setting you need to change to tell it to point to onboard ...

Other culprits could include bad RAM/Memory... fried processor, or bad motherboard....

Try pulling out the RAM , and inserting it into another slot that is supported.... to rule out a damage memory slot.
