Replying here instead of starting a new thread. It sounds like the OP and I have close to the same problem. I have an eMachines T3624. Tonight my daughter was playing and the monitor suddenly switched itself off, going to the screen that tells you the monitor is working correctly.
That screen only comes on if the tower is not turned on. Except, the tower WAS turned on and seemed to be running normally. I'm knowledgeable enough to troubleshoot some problems, but this one is beyond me. I can't troubleshoot from the actual computer because, well, obviously, I can't access things I can't see.
I tried all the obvious things, making sure all connections were good and seated properly, shutting down the comp for an hr or two(I thought something may have overheated). We haven't changed or added any hardware/software, except for windows updates in the last 8 months.
I've never had a single problem with this comp, for all the bad things you hear about eMachines, it's been a great one. I would really like some ideas on what this might be and ways to narrow the problem down more. I really doubt it's the monitor as it works enough to tell me it's working. But what do I know?
Thanks in advance.
Editing to add: Hope I can make some sense here (and hopefully not hijacking this thread). There are two different places to plug the monitor into the tower. Where it was plugged in at was the place we have had it since day 1. So I unplugged it from there and hooked it into the other place. That worked...kind of.
Upon starting, big red x in the tool bar, asked me if I wanted windows to automatically correct color settings and depth (the display is totally whacked). Checked yes, nothing happened as far as I could tell, display still messed up. Went to Display Properties to change the resolution, can't. It is stuck on 640x480 and the lowest color quality 4 bit.
Went to troubleshooting, selected the appropriate reference. Wants me to check if I have the correct monitor selected for use, all it has to select is default monitor and I can not select "Properties"(still using the same one we bought the system with). Moving on to "No, this didn't help me"
Wants me to check for drivers and update them. No way to select for updating drivers, but it does tell me the device is working properly. Next, please...
Does Windows support my display adapter? Yes, yadda yadda, so on and so forth. Wants me to check hardware acceleration and change it to "none" Again, nothing..
Is my BIOS out of date? Okay, go to Intel website to check on updated video BIOS and find out Intel no longer provides support for the video card we bought 1 yr ago...nice. I have e-mailed eMachines about updated INF for the monitor and the latest system BIOS. Not expecting much help there. The support site doesn't even have a search feature. /boggle
Beyond that, troubleshooter is unable to solve my problem.
I check windows updates, and there are no updates for my computer. I finally figure out how to get windows to check for updates for my video driver, no help.
So I go back to I cannot install my monitor(grasping for straws here) and it takes me right back to the second step of this whole thing which I cannot complete because the option is not there. After that it takes me back through all the options I've already tried.
Is there anything I missed? I can not figure this out and it's going to drive me nuts. The comp runs fine except for the crazy graphics.
