System keeps restarting

  1. Ok, Lately, my computer has been restarting alot. Usually in games or right after i quit out of a game. Its getting annoying. I dont really think that this problem is caused by overheating as when i am playing a game the CPU reaches about 45 - 50 degrees, which i think is normal. The GPU reaches about 70 degrees while in a game but since when does an overheating video card cause restarts, plus that temp is perfectly normal for my card (6600GT). The mobo chipset sits at around 35 degrees, which again i think is perfectly fine.

    These are my system specs.

    CPU: Intel Pentium 4 (Northwood) 1.6Ghz OC,d to 2.32Ghz
    RAM: 512MB
    Hard Drive: 320GB Western Digital
    Motherboard: Asus P4S133
    Video Card: Nvidia GeForce 6600gt AGP (Sparkle)
    Power Supply: Thermaltake XP-550 430 watt.

    As you can see, i have overclocked my cpu quite a bit, but raising the vcore doesnt do anything, the system still reboots.

    I am beginning to suspect my power supply. It is an extremely cheap generic unit and has some very bad reviews. Apparently, its a 300 watt not a 430watt. Thermaltake apparently just put a sticker on it that says 430 watt.

    So could it be the power supply? Again, i dont think the issue is overheating as all the temps seem fine.

    Any suggestions?

    I would also say PSU but try running memtest first. Download it and burn an ISO and leave it running overnight. If that comes up clean, replace the power supply for something like a Seasonic S12, Corsair HX series or Antec EarthWatts.
