Hi all. I know this kind of problem is tricky since it's intermittent, but so far has always occurred some time after a reboot. But there are particular symptoms I'm hoping someone else has seen. (By "freeze" I mean the images on the monitors freeze and the power stays on, but the keyboard and mouse have no effect, and the HD light shows no activity)
My config:
Antec case w/500W Earthwatts power supply
Biostar TA760 M2+ motherboard
4GB DDR2 800Mhz RAM
ATI Radeon 3400 fanless PCI-Express vid card
Set up for 3 monitors, one connected to the onboard ATI 3200 Radeon's DVI out, the other two to the two DVI outs on the 3400. Using onboard Ethernet via a wireless-N "gaming" adapter for internet access.
I've tried re-seating everything but the problem persists.
PC originally had Win7 32b w/a Samsung 1GB drive when it started exhibiting the problem.
Now has newly-installed Win7 64b on a different 1 gig HD (Seagate), still exhibits the problem.
Unfortunately I don't have any other known-good parts to replace with.
Doesn't seem to depend on what I'm doing, either.
Peculiar symptoms:
- The two monitors connected to the 3400 just "freeze", but the one connected to the onboard 3200 goes to sleep, saying "no signal".
- Clicking the button on my MS wireless mouse+keyboard base station, plugged in to USB, has no effect - normally it would start flashing while looking for devices to talk to. So it looks like it's not getting power over USB, even though the PS is still on.
- Neither the reboot nor main power switches on the front works, even though the PS is running, and when the PC is working those switches do work. Once the system freezes I have to reboot via the PS power switch in the back of the PC. This points to a hardware problem, since whether those switches work should be outside any software problems, as I see it.
Any ideas? Thanks!
