Windows 7: New graphics card causing kernal power

New graphics card causing kernal power

So I have just got a new GPU the gtx 550ti 1gb and it's causing my computer to shutdown randomly (Usually happens when i play a game). I forgot to uninstall my gforce 8800 GT drivers but i did so after installing the new card i also used drive sweeper to clean the drivers that where left over. How-ever i re-installed the drivers to my current graphics card and i am still having the same problem as before the computer shuts down when playing games or sometimes browsing the web but it works perfectly fine in safe-mode. Any suggestions?

It's only been 4 hours.

And it sounds like your Power Supply is not up to the job.

What are it's specs? Wattage, 12V amperage etc. Is it a brand name or a yum-cha generic?

Hi,
You can read the specifications of your card on the following link : ASUS Ultimate GeForce GTX 550 Ti Video Card Review - The ASUS Ultimate GeForce GTX550-Ti - Legit Reviews

"The ASUS Ultimate GeForce GTX 550 Ti 1GB video card requires a 400 Watt or greater power supply with a minimum of 24 Amps on the +12 volt rail. It also requires that the power supply has one 6-pin PCI Express power connector for proper connection. It should be noted that the NVIDIA minimum system power requirement is based on a PC configured with an Intel Core i7 3.2GHz CPU. If you want to run SLI we have been told that a 500 Watt or greater power supply is suggested by NVIDIA. NVIDIA refuses to give +12V requirements for SLI, which is strange since they suggest them for single card solutions. Notice that ASUS has the power header for their GeForce GTX 550 Ti comes off the top corner of the video card rather than the end of the card. This is great for those with small computer cases."

That is the point! maybe your PSU has enough power to start the card, but once you launch an app that requires more graphics, your GTX 550 fails due to a weak PSU!

That's just my opinion, maybe I'm wrong, but i gave it a try

Fill in your detail system specs!

I have a power supply that's 500W. I'm guessing that's the problem. When i play lower end games it works fine but when i play skyrim etc it shuts off instantly.

If figured out the problem its the PSU after all.

I suppose you are going to change your PSU with a more powerful one. Therefore i recommend you something like this Newegg.com - CORSAIR Enthusiast Series TX650 V2 650W ATX12V v2.31/ EPS12V v2.92 80 PLUS BRONZE Certified Active PFC High Performance Power Supply
Maybe even stronger, depends on what other components you have.
