I was told to make a new topic about this, so here it is with a pseudo-brief recap.
First, hardware stats...
Gigabyte gigabyte GA-M57SLI-S4 motherboard
AMD 4600+ cpu
Antec True Power Trio 650w PSU
2 GB RAM
eVGA GeForce 7950 GT
1 HDD @ 320 GB, 1 HDD @ 250 GB, both SATA sata , both 7200 RPM
HP W22 22" widescreen LCD
Windows Vista Ultimate 32 bit
- I was playing a game (Spore, although I think its irrelevant) and about 10 seconds into playing it, my monitor went blank, saying it had no signal, and then into Sleep mode. Once in a blue moon I get video driver crashes that do something similar, and then the screen comes back in a few seconds and I continue on my way. Not this time. Did a hard reboot.
- The computer began booting as normal, and then shortly before the login screen, the monitor again went blank, saying no signal.
- Computer makes a noise (not a POST beep) when it powers on... sort of a hum, followed by a lower-pitched hum, but boots normally (albeit with no display).
- I took the video card to work to test it out, it tested out fine.
- I purchased a new power supply, which didn't change anything.
- I purchased a new motherboard, which didn't change anything.
- I purchased a new CPU, which didn't change anything.
- I took the system (without the monitor) to work to test it out, and it works fine there. Had it booted for about half of the day on Friday until I shut it down.
- I have replaced or switched all cables involved.
- I have tried a different monitor.
- I have tried both VGA and DVI outputs on both monitors (although my video card only has DVI inputs).
- The HP w22 monitor, when connected to my girlfriend's laptop, works just fine.
- I have even tried using different outlets on a completely different circuit.
- I have tried the other PCI-E port, although I'm not familiar with SLI at all, so I'm not even sure that having a single video card in the PCI-E_2 slot works, but even so, no change.
- I have made sure all connections are clean, and I have made sure that the card is securely seated in the slot.
The computer boots just fine, and shows a display when connected at work. The monitor works just fine when connected to a laptop. When the computer is connected to the monitor, there is no display. I am going to visit my mom tomorrow, and will be taking the entire system (monitor and all) there, to see if there is some strange power situation going on in my apartment, even though every other electronic item (including a 42" LCD, XBOX 360, etc) works just fine. I have contacted HP and they were very little help.
Sorry for the long topic. I've been at this since last Thursday trying to get it to work, and I am officially stumped.
