The ugly monster growls again! Lost video again, maybe after 9 hours operation. Switched to #2 video port, video good! That was last night.
This morning, had an older LCD monitor on #1 port, the NEC monitor on #2 port. Same problems as before.. berserk video after 5 mins. and had to do several hard resets. Guess the GTX280 has been damaged from the "bad caps" plague. Weirder yet, no desktop on #1 video, only on #2 video. Then the mouse pointer is gone on #2 port, only #1 port now!
Looks like I have to get another video card. Image

A curse on whoever is responsible for the "bad caps" plague. They should be made to muck stalls with bare feet for 10,000 hours!!!
But that is a personal thought. Image

Edit 20:45..05/18..
Shut the system down until a new video card is had. Bad artifacts, system freeze.. several hard resets and still problems.

Check the power supply as well Karl... This cr*ppy cap stuff is everywhere...

The PSU is an Antec 650 watt TP3- 650. Antec touts that they use only high-quality caps in it. Have checked voltages several times, and all are within +/- 1% under load.
The replacement mobo is identical to the old, except for the BIOS date.. and quality caps are on it.. not questionable ones. Did check that!!
The video stays good if only the desktop themes and F@H screen saver run. But if doing the F@H process or DVD video, video goes berserk.. and system freezes. Have checked that the refresh rate and resolution are as set. Power scheme as set also.. the video and hard drive 'never shut down'.
The video card is locked down solid in its slot. No other add-in device cards.
Only other major component now suspect is the video card. Did a memory test, came through great. BIOS settings for bus speeds are at default. Memory speed is set via SPD. The 1394 feature is disabled, as too the secondary SATA controller. Only one hard drive. Diagnostics show system temps well within the "normal" range.
This is costing me twice what it should have. :(

Update 05/23..
Got a 'manufacturer refurbished' GTX280 on eBay for about $150.00 USD. Should arrive in maybe 3~5 days. If this does not cure the problem, will go with a 100% new GTX460.

Got the replacement GTX280 in the mail today. Back on line at 15:00 hrs. EDT.
Doing the F@H process, will see if all is OK.
Windows 7 needs an attitude adjustment! Even if the same device is replaced, it wants reactivation!!!!! PDT_Armataz_01_02
Had to reactivate with replacement of an identical mobo.. and now the GTX280.

Something with High-Def Audio device changing as well so a multi-component swap that can trigger a reactivation too? Something along those lines...

Could accept the reactivation issue if the device type or model was changed.. but an exact replacement, maybe only an inception date or BIOS date change? Embedded serial numbers?
True, MS has a severe problem (most other industries too) with piracy and counterfeiting, but this is a bit over the line.
The system worked great yesterday, 15 hours folding. Exhaust temps are similar to before.
Going to keep an older Viewsonic 15" LCD on it as default. The screen has a blue cipher down the center, but not a problem.
Did note one other change. The HDD activity light was on constant with the other GTX280, now it blinks randomly.. normally!
Hope I can find a repair site for the old GTX280. If about $100.00 USD cost, worth it. Just don't have the patience and steady nerves anymore, to open it.

Can't believe I have the video problem again!!!
Shut down properly Sunday at midnight, gave the system at least two minutes at low-load to properly cool down, so no 'heat-soak' effects.
This morning, the problem is back. After even just the F@H screensaver, the video is berserk and the system doesn't respond. My patience with this is near the boiling point!!

After some testing, all voltages are normal.. no sign of any bad caps on the mobo. The memory tests out perfectly. Video is 'solid' if kept off the F@H process or screen saver, up to 1 hour! Choked on the Sandra GPU testing.
So going to get a GTX460 for $ 225.00 USD, 100% totally brand-new. Image
Delivery by June 12th. Then here we go again, Win7 reactivation????
Specs on the GTX460:
Graphics Clock 650 MHz
Processor Clock 1300 MHz
CUDA Cores 336, 1024 meg DDR5
Max. GPU Temperature 104 C.
Max. Graphics Card Power 150 W @ 12v.
Requires one (1) 6-pin auxiliary PCI-E 12 volt power set.

that's interesting, because i used to have a 560, then a 560ti, then two 560ti's in SLI and now a 660ti...and during all the swapping in and out and RMAs/etc, i never had to reactivate my Win7 install...
