I picked up a Compaq r3190us and it has a display prob. Boots up crisp and sharp but within a couple minutes, the screen appears as if unit is receiving alot of vibration, multiple verticle and horizontal lines and then display will black out. System blue screen of death came up for fatal fault and system reboots. Works fine if I uninstall display adapter thru hardware manager and use generic drivers. Is this a vid card prob or a HDD/software issue? If a vid card prob, does one know of a comp card I can replace it with? Thanks for the help!
