So last night my computer showed 12 critical updates to install. I started the update then switched off the monitor. Came home tonight and noticed the cooker clock was flashing which is a sure sign I need to go around to reset all the alarm clocks. Pressed the monitor switch, cant remember the exact screen but its showing the blue screen saying theres an error. Ive tried to use hps rescue menu to restore back to a previous backup ( I tried 4 different dates) all the efforts say restore failed 'missing vgx.dll from the restore point' there seems to be an option to reset to factory but that would be major ball ache having to reinstall programmes and set everything up again. It seems the hp restore menu might be slightly different something else I found. I kept pressing f8 started in safemode then somehow managed to find another menu which had a 'restore from image' - I think. If I can some how figure out how to find it again is there any chance it might roll back to a previous restore point ? Tried for 2-3 hours earlier and in the end had to walk away lol. I noticed there are programmes that apparently scan and fix missing vgx.dll files, do they actually need a functioning pc to work........do they even work ? Any help would be gratefully received. It'll be bugging me at work tomorrow knowing I need to somehow fix it.
