Shut down

Hello everyone, at a loss at the moment... had an older laptop in storage for awhile. Had a broken screen which I usually just wired to the tv... decided to fix it and boost the RAM while I had it apart... never had any problems with it before.. so I do the repairs and everything turns out fine.. system wants to do a run on it and determins I have a threat on it... c:NOVADIGMMANAGEMENTNVDKIT.EXE
Do it asks me to quarantine it or ignore, I chose to quarantine it... says it has to do a reboot and to close out all my files. It then proceeds to do the restart, but then never does the starting up again...? I tried the power button, only flashes the yellow lightning bolt.... like the battery is dead and needs to charge, but doesn't light up (charge mode) when I plug in the charger... nothing, tried both chargers I have for it and nothing. Was reading about this exe on Google and wondering if I took out a main process or what?? 1/2 the pages say it's a program file while the other half claim it's a trojan.... not sure what to do???? Any help would be greatly appreciated !!!! Computer brand a D model are HP Compaq 6710b if that helps.. thanks again in advance !!!!
