AGP Failure?
Hi,
Soltek SL-75FRV Athlon XP2000 GeForce Ti-4200 2xHDD 1xDVD+/-RW My box has been switched on permanently for nearly four months. I've been away on holiday for a week and decided to power off. On my return I turned the box on but there was no signal to the monitor. The disks were spinning but I couldn't see anything. I wiggled a few cables etc before deciding to fit an old Riva TNT2 AGP card. This worked fine. Ahah! The 4200 must be knackered - great excuse to buy a 6600GT. No joy - the GT at least allowed me a glimpse of the Soltek BIOS splash screen then it froze. I tried a GeForce 5200 with the same result. In fact the 4200, 5200 and 6600 all exhibited the same symptoms: at some point between power up and logon the screen would either freeze, be garbled or not send a signal to the monitor. At this point I replaced the power supply (350W). Still no joy - only the Riva TNT2 card works which is as solid as rock. I've run out of ideas. Any suggestions? Martin |

Martin Try popping the CMOS battery for about 2 days. That'll drain the system completely. Listen for any beepcodes on startup. It could be RAM, the microcode on your CPU (pre-boot code), or a blown board component (caps, mosfets, chipset component). |

Tried this but no joy. Box Ok with TNT2 card but 4200, 5200, 6600 all fail.
I'd thought about the RAM but discounted it as the box runs fine with the TNT2 card. Is it a motherboard swap next, then? |

The TnT2 card is running at AGP 1X2X-3.3v The other cards run at either 1.5v or .9v, or 2X4X8X The 4200 should run at 3.3v Can you get a picture with the 4200 in long enough to get into BIOS? Since that's the card you had in the first place, it should be working. Might be the power regulator for the AGP bus is going south. |

I can get to the BIOS if I use the TNT2 card - all the others now barf at
the BIOS splash screen. Incidentally, I tried to burn a DVD this weekend using NERO. All attempts have failed - the burn succeeds but during the verify the box restarts. I've used three different media - all with the same result. Could it be my 512Mb RAM stick that's going bye bye? "McGrandpa" wrote in message ... "Martin" wrote in message Tried this but no joy.

Maybe. Download memtest86 or memtest86+ and run it overnight. http://www.memtest86.com/ http://www.memtest.org/ -- Rich Webb Norfolk, VA |

I've just replaced the mainboard and everything is back to normal.
