jhbodle Posted October 31, 2005 Posted October 31, 2005 My board is finally running pretty well apart from one problem. If I shut down the PC and then try to switch it on a few minutes later the PC will not boot. I get no VGA, just a series of long beeps (which according to my Big Book of Bios Beeps for Boys is a 'no memory present' error). If I leave the PC for an hour or more and try switching it on again it then works. Removing the power cord from the PSU does not accelerate how quickly I can turn it on after switching it off. ANything less than around 50mins is no go. I think this started happening after I upgraded the BIOS to 702bt - which is a shame cos it solves my other problems (typical!). Should I flash back to another BIOS (which one?) or is there another solution? Hardware: DFI NF4-SLI-D, Athlon 3500+ Winchester (stock), OCZ VX PC4000 2x512Mb @ 200MHz 2-2-2-8 3.2v, Vapochill SE, PC Power & Cooling 520SLI Deluxe, 2x Leadtek GeForce6 6800GTs in SLI Quote Share this post Link to post Share on other sites More sharing options...
Guest thespin Posted October 31, 2005 Posted October 31, 2005 Easiest thing to try is different memory. Then I would try another psu ... but I would bet on the psu ... Quote Share this post Link to post Share on other sites More sharing options...
davidhammock200 Posted October 31, 2005 Posted October 31, 2005 He has the best damn PC PSU made! The RAM is top of the line OCZ, all the parts look to be premium grade. BIOS maybe? :confused: AMD Athlon64 3500+ WinchesterVapochill SE Cold bug? :confused: Quote Share this post Link to post Share on other sites More sharing options...
jhbodle Posted November 1, 2005 Posted November 1, 2005 I think it is the BIOS. The Vapochill has always been fine because its only a baby one that doesn't get that cold. Trouble is, what BIOS is the best one to roll back to? Am I gonna have to move my memory back to the Orange slots (they are in the yellow ones at the moment)? The reason I like my current BIOS so much is because it's the only one that doesn't give me errors in MemTest86 near 250MHz (after a LOT of tweaking). One other thing I guess I should mention is that the PC does seem to freeze after about a day of use - the VGA signal will suddenly be lost and it no longer responds. I still haven't got to the bottom of that one yet - all temps and voltages seem to be OK, and it happens even with the CPU at 1250MHz and the RAM at 200. Somethings up...
