Processor AMD Athlon II X4 640 3.00GHz
Motherboard Asus M4A87TD
Cooling Nexus RealSilent 120 mm
Memory 2 * KingMax 2GB DDR3 1333MHz CL9
Video Card(s) Gainward GeForce GTX 460 768MB DDR5 192-bit
Storage Western Digital 500GB SATA-III 7200rpm 16MB Caviar Blue KX
Case Antec VSK-2000
Power Supply Sirtec HPC-500-H12S
Benchmark Scores Win 7 / 64
Motherboard: Asus M4A87TD
AMD Phenom X4 II SKT 640 3.00GHz AM3 box
Memory: 2x Kingmax 2GB DDR3 1333MHz CL9
Video Card: Gainward GeForce GTX 460 768MB 192-bit DDR5
HDD: Western Digital 500GB SATA 7200RPM 16MB Caviar KX III
PSU: HPC-500-H12S Sirtec (http://www.highpower-tech.com/eng/pr...20100530203115)
Case: Antec VSK-2000
Optical Drive: Optiarc AD-5260S Black Bulk

Symptoms and other details:
- It worked at work (5 hours uptime without reset)
- With an regular extension :
1. Reset after 2 minutes
2. Restarted: it resets again after 3-5 seconds
3. Restarted after an half an hour: it resets everything back to 3-5 seconds
- With a protection strip V-Mark Extension SGE with shock protection:
1. Starts without problems
2. Install Windows 7 (64) + about 5 restarts for updates
3. After a few minutes monitor is showing : windows is shutting down
4. I power up again and now it only stays for a few seconds up then it shuts down again itself then power up again itself. I powering off and remove the cable from PSU
5. After a few hours i start it again without the DVD-drive, and it loads the windows
6. I shutdown from windows manually, and after 10 minutes it starts by itself just to shutdown again.

Any suggestions what it might be? I would hate to have to bring it to warranty.

Also (maybe related) DVI worked and after a while it stoped and now only works on VGA :
I try to connect GTX 460 768 MB with a 23 inch Philips monitor (1920 x 1080)
I tried the following:
1. Output DVI-D video card with DVI-D monitor
2. DVI-I output video card with DVI-D monitor
3. Other Single-Link Cable still the same two tests
4. Reinstalled the video card driver 5-6 times
a. installation CD (260.99 version)
b. from Nvidia on site (266.58 version)
c. from the Gainward site (266.77 version)

Instead I go to the VGA. If I put the DVI monitor to say "no video input" -> sleep mode -> Analog VGA (D-Sub).

I must say that initially worked on the DVI-D DVI-D video monitor with the Single-Link cable.

Also when i am playing HD movies i get image freezing, video and audio lagging behind.

Maybe try 1 stick of RAM, remove MB battery and set MB to load defaults.
How many amps on power supply? Seems low if OC.
Also look at MB and CPU temps - what do they show?
What does power supply in BIOS show?


Well sorry - as I was typing I saw you may have found the problem.
Wish you luck

are you sure thats not because your monitor is locked to VGA, or the DVI cable is broken?

is this in windows or the BIOS/POST screen that you only get VGA? are you leaving the VGA connected when you try DVI?

Can you try the monitor out on another computer - just to rule it out?

problem is that my laptop only accepts VGA input not DVI so i cannot test it properly.
I have both cables connected at the same time (DVI and VGA)

once its in windows, it'll default to one screen, your primary.

if thats your VGA, then the DVI will be detected as a second monitor and not be enabled.


turn the PC off, disconnect the VGA and run only the DVI. see what happens.

Monitor still reports no video input.

I also tried with a new video card (8400GS) --> Same results (no video input)

Maybe try 1 stick of RAM, remove MB battery and set MB to load defaults.
Already tried that --> Same result

Also look at MB and CPU temps - what do they show?
This is idle
MB 22 Celsius
CPU 28 Celsius
GPU 37 Celsius
