Random Freezing. Is 600W PSU enough?
Hi. My new build (thanks to good advice here) is working great. Lots of power. Situations where I used to have to freeze multiple tracks just cruises now! And latency problems have greatly improved. But - ever so often - Windows will freeze. No mouse or KB movements. I have to push the button to reboot. Oddly, it never happens when I'm using it. Only when I leave it for a while and return. And it doesn't do it every time. Temps are fine - around 28 deg C at idle. I have ran Prime95 (temps peek at about 58 deg C) with no errors and memtest6 for 8 hours - no errors. I can't help but wonder if I may have undersized my PSU? Although I checked at an online power calculator and it appeared to be enough.
Here are the specs:
Windows 7 64 bit
i7-2600K (not OC'd yet. Waiting on PC to become stable first)
Gigabyte GA-P67A-UD3-B3 motherboard
Mushkin blackline DDR3 RAM (1600) - 8 BG (2x4GB)
Noctua NH-D14 CPU cooler
MSI N450 GTS video card
Corsair CX600 Power Supply
Cooler Master Case with 5 case fans
3x 1 TB HD's (2 of them are SATA II and 1 is SATA III, all 7200 RPM)
SIIG FW card (TI chipset)
All drivers updated and all Windows updates installed.
One other possibility - my GPU arrived DOA so I had to RMA it. While I waited I installed a GeForce 7300 LE to hold me over. Once the new 450 GTS arrived, I swapped. Freezing has occurred with both cards. Should I have "uninstalled" the 7300? I simply swapped them out and updated drivers. Any chance those old drivers could be the issue? How would I uninstall?
I've tried with/ without FW card and interface. No effect. Tried different mouse/ KB - no effect.
Suggestions? Hardware issue or software issue?
Thanks, as always!!
