I am working on an older Gateway running XP professional which would not boot. I tested the PSU and determined that it was bad (totally non responsive) PSU tester agreed. I installed another new PSU and now it will start a power up and then goes dead. The old one was in a power up/down cycle. I visually inspected the MB and found 2 bulging capacitors. I ordered and installed the new MB and have the same issue. I have disconnected the HD, dvd drive and only installed 1 gb ram..still same results. The processor had plenty of thermal compound and I am confident that the memory stik is good. I think maybe that the system took a voltage surge because of the symptoms. Any help would be appreciated.
