Story: Been missing having a nice old desktop since college has shifted me to use primarily laptops, so decided to move my old PC from home to my apartment.
- PC was working previously at home with no issues.
- Monitor (ASUS VS278Q-P) newly purchased a few days ago.
- When I first hooked up the PC to the Monitor, it worked, but resolution was UGLY. So I changed it.
- When I first connected it to the monitor, it had been defaulted to 1024x600.
- I changed the resolution to 1366x768. For some reason the PC did not display the option for 1920x1080, the monitor's native resolution.
- After changing resolution, I figured I wanted to reformat the computer since it had years of junk on it anyways. After I turned it off, that's when the computer no longer outputs signal to monitor.
- Because of 4, I can not see/access Safe Mode (F8), BIOS (F2), or Alternative Boot (F12)
I have searched online endlessly for the past 2 days, and I've been trying everything that everyone has been suggesting:
- Reset CMOS. Have both pulled battery and used CMOS jumper.
- Took out RAM to see if motherboard beeps upon startup. (Yes)
- Reseated all components.
- Unplugged computer, pushed power button for 5 minutes (power cycling)
- Unplugged all components except for CPU, RAM, HD, Video Card
I'm getting pretty frustrated at this point, and don't know what else to do. I feel like it shouldn't be a hardware issue, since it literally worked when I first tried it, then stopped working 15 minutes later. I don't really want to buy another computer, I bought my monitor because I figured, "Hey, I have a pretty decent computer back home which I can use to just do my school programming and stuff.", NOT because I want to have a gaming rig or anything.
Other information:
- Monitor works flawlessly when connecting my laptops.
- PC has no mobo onboard-display port
- Connecting PC to monitor in this fashion: PC(only has 2 DVI ports)->DVI-HDMI Adapter->Monitor(HDMI port)[Only has HDMI, Displayport, and VGA)
- All fans in computer spinning, components seem to run.
- When pressing F8 for Safe Mode, there's no signal on the monitor still, but I do suddenly hear a bunch of beeping if I hold down F8. I searched online, and found this may just be "buffer overflow", but idk..
Any other suggestions??
