Thanks for taking the time to read this. Here are my computer specs:
Dell XPS 8300
i7-2600 (8 MB cache 3.4 ghz)
12 GB DDR3 SDRAM 1333 Mhz 2x4 GB 2x2 GB
AMD Radeon HD 6670 1GB DDR5
Windows 7 Home Premium
Computer purchased in late 2011. Monitor is an LG and is about the same age.
A few months ago I performed some Windows updates on my computer then restarted. When the computer rebooted, I got power but no signal displayed to the monitor. I troubleshooted the connections to the monitor and confirmed that the monitor was working fine with a laptop. Despite several attempts to cold boot, I was still not getting a display on the monitor. At about the same time, I lost the wifi card connection and had to use an ethernet port to hook up my router to the computer so I would have internet access. I disconnected everything and opened up the computer. I dusted everything thoroughly, closed up the panel, and plugged the computer back in the outlet about 30 minutes later. The computer booted up as normal, with display. So I concluded that the computer was having trouble with operation due to dust build-up. I left my router hooked up via ethernet.
About a week or so ago, I had a number of Windows updates stacked up, so I updated and restarted. Same problem again. I followed the same procedure as before and was able to get it working with display again.
Can someone help me determine what the problem may be here? I need to be able to restart and shut down my computer without this issue recurring. Could it be the display card or is it something more serious, like the motherboard? Why would opening it up and dusting it make a difference? Or maybe it has nothing to do with that, just a coincidence. Thank you.
Jason
