Solved hard drive not detected if video card is in

Asus M4a78 pro desktop motherboard - amd...
January 9, 2012 at 12:32:41
Specs: Windows 7, AMDphenom 2/ddr2
I bought a new mother board because I could not get old one to recognize old or new hard drive, Loaded windows 7, new drivers, and all that good stuff and computer was working fine. 4 hour later the system crashed while watching netflix. I could not get anything to work or my bios to recognize my hard drives until I removed my video card...now windows works but crashes a lot and there is a persistent error sound from my motherboard. Windows is sluggish also...any help is appreciated...
also...things I have tried: Unplugged slave hard drive. I had 8 gigs of ram and now i have it down at 2gigs (some success as this helped restore windows somewhat) I downloaded and installed ASUS power solution at windows prompting with little or no improvement. I also redid the thermal compound as this is a new motherboard...(no effect).

Full model means just that. What brand and EXACT card do you have? The power requirements vary widely.

That series of cards pull substantial power from the 12V rail. Your power supply is rated at a total of 24A@12V. That is not nearly enough. That power supply brand is also a crappy brand that probably fudges the numbers. That said, the unit puts out all the power on the 5V rail, which is not utilized that much in modern systems. Buy a much better power supply from a reputable brand.

Post all your specs, including CPU, number of drives, etc.

Did you follow these instructions for the thermal compound?
http://www.arcticsilver.com/methods...
Install Speedfan or similar to monitor your temperature or if you cannot load in windows, check your temps in your BIOS.
List all of your components...
One thing I suspect, is that you may not have enough power for your graphics card.

You have to be a little bit crazy to keep you from going insane.

Post the full models for both your power supply and your add in graphics card. Sounds like a power issue.

Are you running the 64 bit version of Windows 7?

What brand is the video card? Like I said above, the power draw varies widely. Same thing goes for for CPU. Which one do you have?

Geez, I don't care what capacity the drive is. I asked how many. Each drive draws current.

Have a look at this OCZ 550W for $80 + free shipping. There 's a $20 off code + $20 rebate, so in the end, it's only $40. Looks like the deal ends tomorrow:

Well, your processor could be anything from 45W to 125W. I already posted about the graphics card.

You should have posted here BEFORE buying a new motherboard. If your system ever worked with all the same hardware I am surprised.

The #9 response above suggests a cost effective power supply.

The #1 post above advises you about proper mounting of your heatsink. This can cause slowing down as the CPU is forced to use less power.

Boot into the BIOS screens and check the temperatures of the system and CPU. Let the computer idle in the BIOS for at least ten minutes and then check. Post the numbers back here.

Start temp for CPU was 35'c and the mb was 24'c.....after about 15 min it was holding at 43' and 36' respectively.
The above New egg deal is over and I don t really know the specs of what my system requires....good starting point appreciated...the system worked great with the Asus m3a78-em for about 3 years...tried to find a refurb of the same mb, when that failed I went for the next closest thing. I was not aware of this site until recently....I appreciate the help you have given me so far.

Try:
http://www.newegg.com/Product/Produ...
or one of the top few here:
http://www.newegg.com/Product/Produ...
I used their advanced search capabilities to narrow down the choices, first selecting 80% bronze rating, then 500-600Watts, then advanced/single 12 volt rails only. Then I sorted by customer ratings to help to eliminate the ones that typically have chronic problems. Understanding what you want and then making the website show you only that is the best way to find that diamond within all of the junk (the best deals on the 'good stuff').

Was that graphics card installed during that 3 years or is that a new addition?

I am surprised you ever ran that system with that crappy power supply. I still think that is your problem. From your temperature readings your computer doesn't appear to be overheating.

Yeah, I ordered a new one and we will see how it works. I used the advice posted above and I will post here after install.....if doesn't fix it....it doesn't hurt either.

OK, new NFX pro550w power source installed and computer is running much smoother....thanks for all the help, I couldn't have done it with out you.....however if you would bare with me a little longer I could really use some advise on how to give my system a good diagnostic test to see if it is performing properly....I am having a lot of trouble getting the latest Nvidea driver to install for my video card (gf 9800gt) and ATI won't let me uninstall or disable...

Last week I changed from an ATI to a Nvidia card and had problems uninstalling CCC and the ATI drivers. I found that DriverSweeper totally remove all traces of them.

Be aware though, since Malwarebytes reports DriverSweeper as a "PuP" (or at least its installer), so it may be a good idea to uninstall it after use.
