Pc starts up and shuts down repeatedly and no video
Just installed a supermicro P4sct ll w/3.4ghz cpu and 4gb pc3200 400 ecc memory, connected are the IDE drive and everything was a snap. after pushing start button, pc runs for 15-20 seconds and shuts down then reboots again and again, no screen to go into setup and no beeps of any kind.Tried using a single stick of ram and tried every troubleshooting technique, I can't see where it may be short circuiting, if you can help, must appreciated.

Re: pc starts up and shuts down repeatedly and no video
First be sure that the ram (ecc)you have purchased is compatible with your motherboard and that it will take a total of 4 gig,make sure you earth yourself out on the case before going inside the pc (static electricity can damage electronic components)check that you have not accidentallyloosened any data or power cables, check cpu & fan is seated correctly and working : then
put back the old ram and try booting up,(if still no good),
put things back to the way it was before the changes,
make sure everything is working as before (refer to the above)
trying the new ram, if ok
this will identify if it is the ram the cpu, or some other problem
it is a good idea when upgrading the pc to do one thing at a time so that it is easier to identify any problems that crop up.

Every pc/laptop will only accept a certain amount of memory. Your probably overloading it. Check in your system info to see how much it can take. Also, make absolutely sure that you have the right memory stick for you pc!
you can upgrade up to 2GB (DDR2) Your computer has 1 memory slot you remove the memory and install a new one. you can use either 2GB 800MHz DDR2 Non-ECC CL6 SO DIMM or 2GB 667MHz DDR2 Non-ECC CL6 SO DIMM
Your motherboard can take any AMD Athlon CPU (this does not include the newer multi core or Athlon 2 CPU's), as well as up to 2 gigabytes of DDR400/333/266, ECC, non-ECC, un-buffered memory. That memory has to be split between 2 dimms as the motherboard will not work with a single dimm of that size. Also, ensure that when you do put memory in that the 2 memory sticks are exactly the same.
4 x DIMM, Max. 16 GB, DDR3 2000(O.C.)/1333/1066 ECC,Non-ECC,Un-buffered Memory Dual Channel memory architecture *AMD AM3 100 and 200 series CPU support up to DDR3 1066MHz
**Due to OS limitation, when installing total memory of 4GB capacity
or more, Windows® 32-bit operation system may only recognize less than
3GB. Hence, a total installed memory of less than 3GB is recommended.

i think your memory timingg pro.if u hace two ram in your pc then try just one ram.
ccheck your motherbord dont touch the cabinet.
also check power cable, smps.
scan your pc with quick heal , avast and symantec antivirus with update definition.
i think most of your ram problem.check your single ram.try this.
Ooh! That motherboard uses RIMMs, not regular DDR memory. And you'll need a matched pair to get it to fire up and permit access to the BIOS. Checking eBay I see you can get a pair of 256 MB modules for less than $10, so your curiosity won't cost you too much.
