I HAVE READ OTHER SIMILAR THREADS ------ My PC actually has the fans / lights AND can't even get anywhere on the BIOS. 4gb ram 7950 GT 3.44 GHz Intel Pentium D 250gb HD 1 CD ROM Foxconn P35A (mobo) My mom took my PC away from me, I got it back and it is retarded now. I start the PC, the fans come on, lights are all good, then about 2 -10 seconds it shuts off and then comes back on by itself. When I turn the power on, the monitor does not show anything at all. I have tried many of different things: Different PSU ( problem is not the PSU ) D/C the CD ROM / HD ( so it can't be one of those as a failure ) 1 stick of RAM ( my memory is fine ) Checked ALL of my cables, they are connected properly ( checked many of times, unconnected, then reconnected alot ) Replaced the grease between heat sink / CPU ( can't be my CPU or overheating problem ) Heat sink / Fan is properly mounted ( not loose at all and is flat ) All of the aluminum capacitors on the mother board are perfectly fine ( not leaking / and are on proper ) Reset the mother board a few times.... well thats MOST of the stuff I have done, there is probably more but I can't think of what else I have tried at the moment. And BTW, can't access BIOS so don't ask if I can get into it. Any help would be appreciated.
