I have a Win7 Pro 64 bit, sp1 system that I built in 2011. For the last two days my system will freeze; no mouse, no keyboard access and the only remedy is a hard stop--happened 7 times over 48 hrs. One of the times that it froze it came back on its own and I did get a little message bubble in the tray stating that 'Nvidia Windows Kernel driver V347.52 has stopped working and restarted....' so I've been researching that as a possible issue that is causing my problem.
Here's a partial spec list if you need more let me know:
Gigabyte GA-X58A-UD3R MOBO
Intel i7-950 Bloomfield CPU
3, Asus GeForce GT430 GPUs,
6gb (2x3) Corsair XMS3 DDR3, 1333 RAM
6, ASUS VS Series VS198D-P 19" 5ms LED, Widescreen LCD Monitors (added last year)
650W PSU SeaSonic X Series X650 Gold
The Programs that I use that seem to trigger the freeze:
Think or Swim
trading platform with about 12 charts running, each with at least 2 studies, a bloated excel file for data and BSR 6
screen recorder that I use to record the trading day.
Here's what I've done so far:
I checked for new GPU drivers and the ones I have are up to date
I checked my temps and they all seem fine: CPU cores av 48C, 1 SSD/3, 7200 RPM HDDs av 28C, GPUs av 30-40C depending on load.
Then I blew out the entire case, (I had just done this last week so no so dusty), took out each GPU dusted and oiled the fans.
I also went into the Nvidia control panel and set the Power Management to 'Prefer Maximum Performance', based on this article
When I turned on the system and began working with the three programs that I use daily, so far after 2.5 hours I've had no freezes.
The problem is that I've spent tons of time researching this online and no one really had a definitive solution and while so far so good with the bit that I've done, it would be a potentially serious situation if this were to happen during a trade. I'm hoping that you folks may either have 'THE' solution, or can instruct me on other things to check/try to once and for solve the problem.
Thanks in advance,
