PC not booting properly

[chrbal6406]

Hi everyone

I just bought a new computer yesterday and everything went extremely well. I installed a new n460 gtx graphics card and that went well. I ran the machine for about 14 hours with no problems. Today I went to reboot the machine and it hung on the mobo splash screen. I can hit F8 repeatedly to get a boot and everthing seems fine. I can also restart as much as I want with no problem. This is only happening when I do a complete shutdown and then boot. If anyone can help figure out why this is happened or help me fix it I would greatly appreciate it. Here are my system specs.

What motherboard are you using?

I have an Nvidia Geforce 7025 Chipset Motherboard made by MSI. MSI's model is GF615M-P33. BIOS is up to date. This only happened to me for the first day. I reset the CMOS on the board and haven't had the problem since. I am definately concerned about the PSU (600W XtremeGear) running my Nvidia GTX 460 video card though. The PSU has 30A max at the +12V rail but I have read mixed values of how many amps that the card needs (13.3A was what I came across the most at maximum GPU usage). Do you think that I will be safe with this PSU (3 fans running, 1 hard drive, 1 CD-ROM, and no other cards)? What are some symptoms of PSU failure? (Blue screen/computer turns off automatically) Are any "visible" while the computer is in operation so I can look for these symptoms? I definately don't want to ruin my new machine over a PSU.

hi as for your 600w PSU, that should be all good, your cpu uses about 95watts, n460 150 watts, 12cm fans max 4 watts, and so on, the 400 series graphic cards dont need huge power to run, but if you go sli then go for a more powerful psu.

you could have your psu tested to see if it might be faulty, then have it replaced.
Gut feeling = psu fault

hope this helps.
