Hi all,
Apologies for another 'reboot' thread; have searched forum etc + was hoping something specific to my problem might sound familiar to someone.
As title suggests, I'm having a recurring rebooting issue with a new build I've built my gf. Everything works great, except I'm getting random reboots - however, there's never a BSOD and no minidump is ever created (c:\windows\minidump). For every reboot so far (bar one, when I was on firefox) the PC has been idle, just sitting on the desktop.
- The ram passes memtest86+ for ~8hrs no problem and likewise the Win7 boot memory test.
- running Prime95, temps get very hot (high 80s), too quickly on blend (think I need to redo TIM), but system seems stable.
- HDD has been scanned, no 'bad' areas.
- PSU voltages seem stable and within norm (used HWMonitor Pro - know software voltage readings aren't necessarily accurate, but assume it would show if they were unstable or way off?).
- No gfx card inserted.
- Motherboard has no blown capacitors etc.
- All connections on motherboard secure.
- All drivers up to date (station-drivers.com)
SETUP (new build):
- Gigabyte Z77X-UP5 TH (overkill given the rest of the PC I know, but got it stupidly cheap!)
- CMZ8GX3M2A1600C9
- i5 3570k - at 3.4ghz
- Enermax NAXN ENM850EWT
- Sapphire HD 7750 Ultimate - not yet connected
- LG CH10LS28 - Blu-ray drive
- AK-HC-05BKV2 - 5.25 memory card reader
- Corsair 550D Obsidian - case
- Western Digital Caviar Green 2TB WD20EZRX
- Samsung 840 Pro 128GB
- GC-WB300D - wireless PCIe card
- Win7 Home Premium - not yet activated
PC reboots sporadically, five times so far (has reset within an hour, left idle and unattended. Equally, has survived an entire night formatting a 2TB WD HDD). It's only ever rebooted from within Win7 - have left a mini build of XP running for nearly 24hrs (from Hiren's Boot CD 15.2) without issues. Equally, I assume said mini build might not use/ activate all the 'bits' of the PC - i.e. wireless card?
Could the wireless card (rev. 1.1, plugged into PCIe4 - included with motherboard) be causing issues? First reset happened whilst I was mucking around with our router MAC address.
I bought HWMonitor Pro to try and look over logs etc when it crashes. Annoyingly, the logs in HWMonitor Pro don't save when it crashes - if I instead record the logs onto another computer, the other computer tends to crash with a BEX64 error before the new PC reboots itself!
I guess what I'm interested to know is...
...does this def. look like a hardware issue, or is there a chance it's still software (despite the lack of BSOD/ minidump)? Anything stupid/ obvious I'm overlooking? Suppose the next step is to start swapping out components - any recommendations on how to test in this way as efficiently as possible?
Thanks in advance,
Rob
