Re:MSI P35D3 Platinum with GeForce 9800 GT, always reboots!? - 2008/12/24 12:06
I have a friend who has this same issue. His system would randomly reboot and when he would put his old GeForce 7800 GT in the problem is gone. I took his card and tested it out in my computer for about five days and not a single issue. I flashed his motherboards BIOS to the most up to date version and still had the issue. All and all with him his computer already had lots of known issues so I got him to upgrade his mainboard, processor and memory so we will see if that fixes it. If so I would point my finger at your motherboard, maybe there is a compatibilty issue.
I would look at some customer reviews on both the card you got and your motherboard and look for anyone who has had these issues. If you cannot find anything there is also a very good possiblity your power supply isn't putting out enough Amps on your 12V rail. Sad to say it but buying a cheap power supply won't cut it for todays cards. Like the saying goes, you get what you pay for. And I just came across this Logisys 575W which has 25Amps on the 12V rail. And I know for my GeForce GTX 260, it has a requirement of 38Amps. I'm pretty sure for a GeForce 9800 GT is something like 26Amps.
I would really look into a higher quality power supply. I hope I was of some help, and hope you can get your GeForce 9800 GT going the way it was meant to. Also here are some brands which make quality power supplies and are very trusted, like OCZ, PC Power & Coooling, Thermaltake, Enermax, Antec and that is only to name a few. But also always look at the Amps the 12V rail can supply.
