Hello everyone I am hoping for some help. My laptop was working fine last night, I either shut it down before I went to bed or not, can't be 100% certain. I got up this morning and pushed the power on, heard sounds (fan, but no windows noises but I don't know if my volume was up), the computer acts like it has booted up. Light next to my power button is blue. I have tried several troubleshooting steps.
Computer is running Windows 7, has Avast antivirus installed
connected to external monitor-no picture
used the windows key, and right arrow on keyboard to restart (heard more computer noise but no sound)
turned sound up using the keyboard
tried F2 when computer restarted
pulled battery, held down power button for 1 minute, put battery back in, plugged in power cord and restarted.
put in music cd, I can hear the dvd drive spinning but no sound (again I don't know if it auto plays)
shined a flashlight at the monitor (didn't see anything)
I am thinking it is my graphics card, and I replaced one in another computer before so I feel I could do that. I hated to buy one and try it thought if I wasn't pretty certain that is my problem.
Can anyone help with other troubleshooting steps I should try or provide any suggestions at all?
