I noticed my father's XPS 8300 running a lot when it should be in sleep mode. I suspected malware keeping it awake. I ran a scan with ESET Smart Security 8 and found nothing. I ran a scan with Malwarebytes anti-malware and it found some potentially unwanted programs. I deleted them from the quarantine. This morning my father could not get the computer to wake up. The power light flashes amber and it makes a revving noise, but does not continue to boot up. I tried holding the power button down to make it shut off completely. I tried unplugging it for a few minutes. No luck. It won't get to BIOS for me to try anything. It is running Windows 7 Home Premium. Windows keeps trying to force me to install windows 10, but I am not ready to. Maybe it tried again. I have read many threads on the 8300 problems. I am thinking of removing the CMOS battery for awhile to reset BIOS settings. What do you think?
Here is some system data. The main change is I added a USB 3.0 card.
