I'm new to the forum and looking forward to some great responses to my conundrum...
I have a an HP Envy 700-230 desktop running on Windows 8.1 (tried Windows 10 about a year ago but switched it back after 2 weeks). Yesterday, I was running my system the way I always do and received the infamous "Your PC ran into a problem and needs to restart. We're just collecting some error info, and then we'll restart for you." message. After about 30 minutes of nothing happening, I hard stopped with the power button, tried to turn it back on, and had a black screen. No reboot screen, no safe mode screen, nothing. I downloaded the Media Creation Tool from Microsoft onto a USB, plugged it in, tried to restart, but again just got a black screen.
Power supply is working, and all fans (video card, CPU, case) are running. There have been no hardware upgrades for a couple of years and I haven't changed any of the peripherals for at least a year. I also know that the monitor and monitor cable is working because I have a KVM switch and the other computer that's connected to the switch is working perfectly (I've had the KVM switch connected for at least a year).
I tried to troubleshoot my hard drive so I turned off my system, disconnected my hard drive, connected it to a SATA/IDE to USB adapter, and plugged it into another computer. I got the standard "USB connect" sound when I plugged it into the other computer, and it was spinning, so I'm pretty sure I don't have a mechanical failure. I replugged the hard drive into the desktop, disconnected all peripheral devices except the keyboard and mouse, tried it one more time, but still got nothing but a black screen.
I'm not sure what to do because I'm getting no response from the system. I could use some good advice right now...
Thanks very much,
