Check the motherboard for capacitors with bulged or split tops or brown leakage around them on the PCB. If it has a fan duct or the CPU cooler covers some, take that off so you can inspect capacitors near the CPU. Same thing for the power supply, open it up and check its capacitors.
If it's critical to keep using this system and it has bad capacitors, then it's worth it to replace them. I had four caps replaced on an old Dell Precision 360 Workstation, despite it being so old it has DDR1 and AGP. It has a 3.2 Ghz Pentium 4 Extreme Edition CPU - was a $3K+ box new. I recently put XP Pro on and sold it for $100 as a super Retrogaming PC to some guy who loves the "Total War" game series.

It sounds like you have a machine that has been running for a long time and has been reliable and stable, and then it suddenly became unreliable and started crashing without you having made any software changes to it. If my understanding of your situation is right, then it sounds like hardware is failing. I would try running memtest86 on it for a day or two (find it in the Grub boot menu). If that fails it's almost certainly bad RAM or CPU; if it does not fail it's probably got good RAM and CPU but there could still be other hardware problems not triggered by memtest. ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
