Client PC started to run slowly, and eventually on reboot said unable to find boot drive (mSata SSD). Brought it to shop, tried booting, and all I get to is the Dell logo. F2 & F12 do nothing. If I press <esc> right after power on, blue bar scrolls below logo, but then nothing. It disappears, Dell logo remains only thing on the screen. Removed all internals (SSD; 2nd HDD, GPU, etc.) and attached HDMI to internal GPU- same results.
I can't get into setup at all. Single beep at boot, but consensus is that's normal. Only other posts I've found indicate Mobo meltwon. Could make sense considering extreme slowdown during its last day running.
Ideas??
