I'm getting garbled graphics on my computer in text mode environments, such as in the BIOS or before loading Windows. However, I don't have any graphical issues in Windows.
Graphics card is a GeForce 8800 GT, on a MSI P35 Neo motherboard model MS-7360.
Edit: Seems the capacitors on the card are bulging. I managed to fix my TV on my own by replacing them (repairman wanted $100!), and I might try doing this on my graphics card. It's a long shot, but I might be able to do this and see if this is the problem.
