+ 0 Votes Could be a couple of things OH Smeg 2 years ago 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. Col + 0 Votes Auto-rebooting and blue screen issue with Windows and Asus integrated video HDSTUDIO 1 year ago I realize I'm answering to old post here, but in case anyone else finds this page and my comment could help, I had a lot of troubleshooting in regards to Win Vista installing and running in regards to this issue. My system would auto-reboot or crash dump every 5 to 15 minutes. I went through just about every possible scenario, including bad RAM, bad HD, bad power supply, etc. After swapping each of those around with others I had in another system and still having the issue, I decided to read a little bit of the blue screen of death to pick up on any clues. It suggested that the video card might be bad. Since I was using the integrated video card on my Asus motherboard, I thought I'd see if it was a video driver issue. So, I installed Ubuntu on the same exact hardware to see if it did the same thing. If it did, it would be a hardware failure, if not, it would be a software. Ubuntu ran flawlessly with no crashes. SO, moral of the story, if you are having automatic rebooting and and blue screens every 15 minutes or so, it's most likely coming from poor communication between the OS and the video card. Update the driver, the OS, or, if you can, switch from MS **** to a new Linux distro and enjoy your computer again...lol. Hope this helps someone. + 1 Votes Have you gone into the BIOS jlholmes21 2 years ago 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. + 0 Votes Depends on what exactly is happening here OH Smeg 2 years ago 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. Col + 1 Votes When does it reboot? Spitfire_Sysop 2 years ago 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. + 0 Votes Why is my new graphics card causing my computer to reboot? Quaint_Data 2 years ago 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??

I have had 2 cards so far that were dead on arrival and had to be exchanged. + 0 Votes what is causing my computer to reboot? Quaint_Data 2 years ago By the sounds of it your question really doesnt have a single simple answer, there seems to be numerous problems and all entirely in different directions as to why you are having these rebooting and dead video cards issues. Rebooting is often caused by bad drivers or over heating. If your system reboots fully back into windows heat the probable cause. Slowing windows again runs into a few areas. If you get a BSOD then it could be a bad driver or a mismatch / hardware incompatibility somewhere or a failing hardware component. To start with how you insert a video card/s may cause a short or discharge off your body, that in turn may have caused a problem on your motherboard If there is swollen capacitors on the mobo >check with a torch> then your system is definately dying and the more load > Games and stuff increases it. if there is large amounts of dust inside the case or on the fans heatsink etc.that will cause heat. there could be dust inside the dimms where you insert the video card, possible cause of damage dead video cards not enough power to provide a balanced system will shorten the life of your hard drive/processor. Under these circumstances I would recomend to you to take the system to a professional and have it thoroughly tested and checked. If it is againg may even be the hard drive itself. Around 3 years of age it requires a major maintinence and cleanup if never performed, more than 3 years of age I'd start looking into all the hardware, and outdated drivers. New hard drives can come cheap so don't measure up for performance. They need defragging. How old is your system? + 0 Votes what is causing my computer to reboot? Quaint_Data 2 years ago Half my top post dissappeared, must have exceeded As I started to say, there seems to be no single answer here, I feel your problem may be in too many directions. Rebooting fully back into windows possibly Heat. No BSOD? The method you insert your video card may have caused a discharge /short, check the capacitors on your motherboard>swollen, use a torch, if there is your system is dying. if this is the problem every time you do stuff heavy with graphics will cause load / stress.
