I was trying to play some games on my computer and had graphics problems. I only have the on-board graphics (no graphics card added yet) but some of the games were extremely basic and still wouldn't run. I checked the drivers since I figured this may be the issue. Every single graphics driver in the listing was disabled, so I enabled a Nvidia one that was already installed on the machine, a HP dx2450.
On rebooting, what would normally take 45 seconds ended up being a blank screen after passing the blue hp screen before getting to the splash login screen. My monitor timed out and went into sleep mode as a result.
Restarting it I can get into grub via a series of keys I found online, but as this is my first time with this particular issue I'm not sure how to fix it. I'd rather not reinstall the system unless absolutely necessary, especially since this was an OEM install by HP.
Don't know how this information could help, but as I already know from most tech forums that it will be asked:
HP dx2450 2.3 GHz Dual-Core CPU 2 Gb DDR2 Ram 80 Gb Hard-Drive No PCI x16 Graphics Card in slot. On-Board graphics only at present.
