Thought I had a hard drive issue but it got sorted out except now my 2400xp mobile will not run stable above about 110 front side bus. Used to run fine up to around 150-160. Motherboard is Asus a7v880, os 2000 pro. Just tried another harddrive that had xp on it and same problem. Could this be a bios problem? Want someone else's opinion before I go messing around with the bios. Thanks.

try updating the bios and setting everything to default. the fsb should be 133 or 166. if it isn't you've hosed your ram, board, processor, or some combination of the 3.

Thanks for the suggestion, smoothcrim, but from day one my motherboard default settings were fsb of 100 with 6.0 multiplier because of the mobile processor. Working values had to be set manually in the bios and I was able to use fsb=150 with 14 multiplier. Now, if I try to go above 110 fsb, it won't post.
Although It is running right now at fsb=110 with 18 multiplier. Think I'll try a low multiplier with a high fsb to try to isolate the problem.

Wouldn't post with fsb=120 and 6 multiplier. Back running at fsb=110 and 18 multiplier. Is there a memory setting in the bios that would cause this? Could this be a memory problem? I am running 2x512mb PC3200 Corsair Valueram. I have a stick of pc2700 Kingston xms around somewhere that I could substiture in.

Athlon XP 2400+
2.00GHz
1.65Vcore
multiplier = 15x
fsb = 133
