| 557767 | 2007-06-10 00:50:00 | Hello, Now and then The CPU Fan and the Chipset fan stop spinning after the system does it's post checks on the motherboard and sound a long beep from the pc speaker. It seems to do it if I leave my computer off for more than two hours. When I power it up for the second time the screen stays blank untill I reboot it again. It seems to clear when I go in the bios and save on exit. The bios clock is always correct. Yesterday I got some strange voltage readings- ATX+5.0v = 3.81V and the Chip+1.5v = 2.01V. But they seem to be correct now. The power suppy I've got is a Liberty 500watt which is only a week old. If any one knows what might be going on please let me know as I don't know what to try next. Any help would be great. Thanks |

| 557769 | 2007-06-10 01:53:00 | HI, My motherboard is a Infinity INF NF SLI-M2, The motherboard book says a single long beep means it's a DRAM error? But sometimes it does it after the bios post checks. Do you think it could be the ram?? I've got two 1GB DDR 622 Dual Channel ram cards. I've changed slots and checked to make sure they are in correctly. |

| 557770 | 2007-06-10 01:56:00 | Have a single stick of ram in and see if you can mimic the errors again (try both). Also try a memtest86+ with both sticks in and leave it going for a few hours. EDIT: Oh and some motherboards require the sticks to be in a certain slot for booting. Or maybe that is only DFI motherboards :D |

| 557771 | 2007-06-10 02:24:00 | Then run Memtest and see if that picks up any faults. Leave it running overnight. trinsic, I have a DFI NF4 SLI-DR and that has no issues with RAM... they are an amazing brand so don't knock what you don't know ;) |

I'd be seriously worried about that. It could fry them. Check the PSU and if thats OK RMA the motherboard. |

| 557774 | 2007-06-10 11:00:00 | I have just finished running the memtest86+ program for about two hours and it picked up no errors in the ram. So I don't really know what's causing the problem. | Rayman (12367) | ||
| 557775 | 2007-06-10 20:11:00 | Just because you ran it for a measly 2 hours does not mean that there is no RAM error... I have seen PCs run fine for 5+ hours on Memtest... then they started to error out... so leave it running as long as you can (over night as I said before will be good) | The_End_Of_Reality (334) | ||
| 557776 | 2007-06-10 22:21:00 | What's the best way to check the psu? What do you mean by RMA the motherboard?:confused: By installing another known working one. Return Materials Authorisation. Return the board for replacement or repair. I doubt its the RAM. |
