I recently built a new system with a GA-P55-UD3 motherboard and am getting random reboots (around 20 so far?). I've tried a number of things and have had no luck resolving this issue. I am in urgent need of help, as this is a work computer and I need to get back to work!
I've been trying to find a pattern, but nothing concrete. Here's what I have so far:
- Has only rebooted while in windows.
- Once rebooting starts, it happens more and more frequently (to the point where I don't even get to the login screen). Leaving the computer off for a while seems to reduce the frequency of reboots.
- It has happened twice while using Virtual PC.
Here are my current specs:
GA-P55-UD3R rev. 1.0
Intel i7-860
4x2GB OCZ3G1600LV4GK
Corsair VX550W
Radeon HD 4350
Western Digital 1TB
Windows 7 64-bit
Here's what I've tried to do so far:
- I originally bought the machine with 2x2GB Corsair CMX4GX3M2A1600C9.
- Installed Windows 7 64-bit. It rebooted a few times. During one boot up, it found errors on disk and fixed them. I could not get to the login screen after this.
- Updated BIOS to F3 and loaded optimized defaults. Didn't help.
- Reinstalled Windows 7 64-bit and all drivers (no Catalyst, though). Ran it on and off during the weekend at home. Ran Prime95 for 15 minutes with no issues. Watch an HD video with no issues.
- Brought it in to work on Monday. It worked until about noon, when it rebooted while in Google Chrome. Rebooted at 4:35 while not being used (I left at 4:30).
- Tuesday I was using it for a couple of hours. It rebooted while in Virutal PC. About 5 minutes later it rebooted while browsing in Google Chrome. Tried fail-safe, did not help. Tried adjusting RAM voltage to 1.64 (1.65 was not listed?). Didn't help. Could not get to login screen at this point. Left it for 10 minutes and tried again, but still couldn't get to the login screen. Left it for an hour and used it for 5 minutes and it rebooted. Left it for a little while longer and it didn't reboot for the rest of the day.
- Exchanged RAM for supported OCZ model. Installed 4 GB. Loaded Optimized defaults. Change voltage to 1.64. Ran a video in a loop for an hour, no problems. Ran the Windows 7 memory diagnostics in highest setting (2 passes). Ran from about 8pm until about 2:30am. It didn't find any problems. Booted up into windows autoamtically and ran until about 7am until I shut it off.
- It worked today from about 9am until 2:00pm or so with lots of usage. Rebooted while in Virtual PC.
- I found there was a new video card driver released yesterday. I installed it.
- I've checked the temperature a number of times, but it is always under 40c for both CPU and MB (something like 39c and 34c). It doesn't seem to fluctuate much.
I noticed after installing the supported OCR RAM, it listed in BIOS as 7-7-7-16 at 1066MHz instead of 8-8-8-24 at 1600MHz. I just ran Speccy and it's showing 7-7-7-19 at 533MHz(???). I'm not sure how to set this to 8-8-8-24 at 1600MHz.
Any help would be greatly appreciated.
