problems with microstar mobo

[leftfist]

Hello all. I'd appreciate any help. Trying to build this PC for my girlfriend for xmas....

Microstar K7T Pro2-A
Athlon 900
Radeon 64 DDR
Soundblaster Live! Value
300W power supply
128 MB pc133
Plenty o fans

So I slapped it together without too many snags... It was running great. But then recently i decided to boot it up to mess around and whatnot... and, of course, it wouldn't start. Power comes on, fans go, mobo beeps a lot, and the diagnostic LED goes 0100 which according to the mobo manual means a memory test error. This actually did happen while i was putting the thing together, and i solved it then by moving the memory module from DIMM 1 to DIMM 3, despite the fact that supposedly it doesn't matter which slot the memory's in. Now i've tried all 3 slots, no help. I've tried 2 different sticks of memory, both of which work fine in another PC. I've tried switching out the power supply. This is particularly frustrating as the system was running fine previously, i made no changes, and now i get this. Any suggestions would be greatly appreciated. THANKS

Mike

Try a different cpu or try your cpu in another mobo. Right now the Duron and Tbirds are the overclockinist cpus around, but they are also the dyininst, from my experience. I've had 2 durons and 2 Tbirds die in just a short 2 weeks. That's more than I ever had PIIIs and Celerons in 2 years. :Q

That's disheartening... Because I don't have access to another socket athlon. My other athlon is one of the older slot deals. Thanks for the reply.

I'm using the same motherboard and had the same problem once. I fixed it by clearing the CMOS by removing the battery. By the way, did this happen because you changed the memory cas setting or bus speed? That's how I messed up mine.

My own Thunderbird 900mhz went faulty after only 6 weeks so I would try checking everything hardware wise just like compuwiz1 said.
