Why is my new graphics card causing my computer to reboot?

By wowgoat270 ·
Put a GT520 in an ASUS desktop. My power supply is 50w higher than what they said the minimum was (which was 300, and I have a 350) I suspect that might be the problem though because when I plug it back into the intergrated graphics it works just fine. Any ideas from anyone else? or do I just need to upgrade my power spply

Could be a couple of things

by OH Smeg In reply to Why is my new graphics ca ...

The most obvious is an incompatibility between the Chip Set of the New Video Card and the M'Board. This is a bit of a misnomer though as I've seen some Video Cards cause a system to not start and then another Video Card from a different Maker but with the same Chip Set work perfectly in the same computer.

Here it's generally the way that the Maker sets up the Video Cards Features and what they use and what they do not use.

The other thing may very well be the Power Supply is overtaxed. 350W is a bit on the Low Side unless you have a Brand Name PS like Antec which is the equivalent to a 500W No Name PS. The easy way to check a PS is to pull it out and if it's heavy it's better than one that is light as the light one doesn't have the ability to produce High Wattages consistently.

So would you think I should switch to a radeon graphics card or something? I really don't think my PS is top notch because the whole rig cost me 400 bucks brand new from best buy. and on top of all that should I go ahead and upgrade PS?

Have you gone into the BIOS

by jlholmes21 In reply to Why is my new graphics ca ...

Hello,

When I put a GPU (graphics card) into my PC with an intergrated chip I had to go into the BIOS and disable the onboard graphics chipset.

Also uninstall the driver for the intergrated chipset before hand so there are no conflicts.

Depends on what exactly is happening here

by OH Smeg In reply to Why is my new graphics ca ...

If the system fails to turn on at all I would be looking at the Video Card being incompatible with the M'Board. Here it all depends on the CPU involved and the Chip Set of the M'Board. If there is a Intel CPU & Intel Chip Set M'Board I would be looking at the Power Supply being the issue.

However if you have an AMD CPU or a Intel CPU without a Intel Chip Set M'Board so your M'Board is a nVidia Chip Set I would be looking at the Video Card being the problem. Quite a few non Intel Chip Set M'Board have issues with Video Cards.

When does it reboot?

by Spitfire_Sysop In reply to Why is my new graphics ca ...

Does it get in to windows? Does it reboot when a graphic mode changes?

On the PSU:
Not all PSU are created equal. They all put out different amps on various rails. A cheap 350W PSU might fail to run a high-end graphics card where a top of the line 300W might do just fine. I would never use a PSU rated this low. I have a 750W and I would say the minimum for gaming is 500w.

Before you replace the PSU, pull out the video card. Update the bios. Uninstall the previous video card drivers. Turn off the system. Install the new card. Turn it back on.

Which windows do you have?
If it's windows 7 then you need at least 800 watts PSU.
I have 850 watts with 4 gig of ram with my nvidia
Did you see a windows message something windows is shutting down to save your system??
Then it's the PSU.
Nvidia right? GT520
Zotac or gigabyte?

WOAH! An operating system doesn't effect the PSU you need to buy. I have a 220watt PSU (yes I ahve an acer lwo profile machine) and I have run a GeForce 8400GS in it perfectly fine. Looknig to get a HD5570 and I know that runs in it.

Oh yes the OS does affect the PSU. Depending on the OS you run you need different amounts of RAM, then depending on how it is set up and how it is using the RAM affects the amount of paging. If you are paging heavily your HDD is being used more. As RAM power drain is negligible then inefficient OS + small RAM will cause higher power consumtion through the use of HDD. If the HDD and the GPU use the same power rails...

PCI SEER in BIOS

by Charles Bundy In reply to Why is my new graphics ca ...

Every so often I have problems with bus parity causing reboots when I add a peripheral card (GPU, 1394, et-al) and have to turn PCI SEER off. Check your BIOS, turn that sucker off and all should be well.
