Random Computer Freezes / Hangs

Hello Everyone, and thanks for taking a read! I have been having a couple of issues with my home PC. Basically the PC will randomly freeze up and just hang, the computer does not blue screen or restart it just freezes the screen and i have to manually shut off the powersupply, this has been happening quite often. freezes can happen 10 minutes to 10 hours between the next one.

My Current Specs are:
Windows Vista SP 1 64 Bit
Intel Core 2 Quad 8200 @ 2.33 GHz
GIGABYTE GA-EP43-UD3L LGA 775 Intel P43 ATX Intel Motherboard
Mushkin Enhanced Blackline 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 800 (PC2 6400)
Western Digital Caviar Black 640GB 7200 RPM SATA 3.0Gb/s 3.5
Antec EarthWatts EA650 650W Continuous Power ATX12V Ver.2.2
EVGA 512-P3-N879-AR GeForce 9800 GTX+ 512MB 256-bit GDDR3 PCI Express 2.0 x16

The RAM and MOBO are brand new from newegg - just recently replaced

Now I have tried quite a few troubleshooting steps myself first. I've completely reformatted my hard drive twice, the issue happens with Vista and 7 both. Also ran MEMTEST on multiple occasions and the RAM comes back looking clean. I've also tried switching Voltage for the RAM, it defaulted at 1.8V, changed it to 2.1, and then changed it to 2.0. The RAM timing is set to auto and is 4-4-4-12 in my bios. I have gone into Safe mode and uninstalled the latest nvidia drivers, and rolled them back to a more stable version (From 196.21 to 186.18) but the issue is still frequent and I am out of ideas and quickly becoming frustrated because it froze twice while trying to type this out! :P Any and all help is greatly appreciated thank you!

  1. Have you checked the CPU temps? That's about the only thing I can think of that might cause the problems.
  2. +1^ and, it could be a possible power supply issue, you have another PSU to test out?
  3. Processor Temperature : 33 °C
    Mainboard Temperature : 21 °C
    Intel Core 2 Quad (Core 1) : 46 °C
    Intel Core 2 Quad (Core 2) : 45 °C
    Intel Core 2 Quad (Core 3) : 46 °C
    Intel Core 2 Quad (Core 4) : 45 °C
    GPU Temperature : 41 °C
    GPU Diode : 41 °C
    Hard Disk WDC WD6401AALS-00L3B2 (Assembly) : 27 °C


    +3.3V Voltage : 3.31 V
    +5V Voltage : 5.07 V
    +12V Voltage : 0.32 V
    VTT : 2.02 V
    VBAT : 3.12 V
    Chassis Fan : 1290 rpm
    Power/Aux Fan : 1167 rpm
    GPU Fan : 35.0%


    Unfortunatley I do not have another PSU to test that. Any other ideas perhaps?
  4. wow, this is a tough one. when does the issue happen, when doing CPU or GPU intensive tasks? Or is it completely random? Also, how often does it happen?

    Another thing you might want to try is taking out one of the RAM sticks and just trying one at a time, there is a chance that one stick may be failing whilst the other is still good...
  5. Randomly, it tends to typically happen less during CPU and GPU intensive tasks. Here lately though it's been happening every few minutes now. I've tried reseating the ram in every type of combination and even tried just running each stick by themselves as well. I've tried increasing the timings to 5-5-5-15 and also updated my bios as well. Unfortunately this has had no impact on the random freezes
  6. Your +12V is 0.32V? Obviously it can't be that low, or you wouldn't have been able to capture that screen; but something isn't right...

    uuuummmmmmm, i can't believe i missed that, it should be more along the lines of 11.89 - 11.99 on the 12v rail

    hi
    I had same problem when I built my first computer it kept freezing at odd times especially when trying to play games. tried everything flashing bios, updated chipset drivers ,reinstalled windows. tried different video card.


    The problem, I'd put memory in wrong slots. should have put them in slot 1&3 not 1&2. computer works perfect.

    what a plonker.
  9. my memory is in slots 1&3
  10. Have you tried updated chipset drivers?

    Any ideas on why my voltage is only showing like 0.52?
  12. My PC restarts randomly, No BSOD, No overheating, Have a Gigabyte ep43 u3dl MB 4 gig Ram GF 9800GTX+ EVGA, I have no Idea what it could be!!!
  13. Please start your own thread. Thank you.
  14. Check in Device Manager to make sure that USB Root Hub and Generic Root Hub Power management feature for "Allow the computer to disable this device to save power" is NOT checked.

    We had 5 machines with this exact issue. Making these changes fixed all of them. Gigabyte could not solve this problem.
  15. Use Windows 7 because vista use double ram.
    and if you can buy maxton hard disk and at least intel corei3 2310 cpu.
    install some fans on your case.
