I Am running a Geforce Fx 5800 ultra, using the NVIDIA 61.77 Drivers under XP service pack 2, Recently I have started my computer to find that on the bios screen there are 5 sets of 3 lines going across the screen, this is when detecting IDE Channels, the next Screen where there is writing it shows this symbol | over all the writing, when the Xp Boot Screen appears there are 3 sets of 3 lines corrupting the image, and then when it gets to the logon screen, it will either Cause a blue Screen showing the Message "***Stop: 0x0000007E (0xc0000005,0xf5e723b6,0xf79c624c,0xf7c5f48) or it will allow me to logon to my pc but with Pink Lines going all down the screen, or the Desktop is corrupted completely. When this first happened I went into safemode, to find the exact same problem existed so it couldn’t of been the drivers, however I uninstalled them and reinstalled older drivers to make sure, finding the same problem I went back into safemode and reinstalled the 61.77 Drivers. Still the problem Occurred. After Pushing the reset button many times the problem went away and didn’t occur again till now (that was a week ago) and today whenever I try to install the Drivers the pc Crashes or restarts, it only does this however when it actually detects the card, because it gets to 31% and when the screen flickers to do a test , the pc Crashes, I have made sure it is not a monitor problem by plugging a 2nd monitor into the port and I still have the same problem. I am currently not using any drivers for the card as the PC Seems more stable (Doesn’t Restart at random) What can be done? I purchased the card last April and it has a 5yr Gurantee. However it was a Pcworld.co.uk Web Exclusive Offer and i cant Contact the maker, Being PNY as im always directed to the french Number for Techinical Support.I Am Currently Looking for the Receipt and i fear they wont let me take the Graphics card back and have it replaced as PNY dont make the FX 5800 Ultra anymore, and they would prob send me a crapper card. Please Help Thanks From Steven.
