Or a stick of ram that system has decided to now work with.
Downsize the machine, upsize the power supply and keep it cool.
Been running my newly-built machine for a couple weeks now, with no problems. Here are the stats: Asus K8V w/Athlon 64, Seagate 120 HDD, 1.5GB RAM, WinXP w/SP2, AVAST Anti-Virus, Norton Utilities 2002 Pro (Norton AV disabled. Been busily loading all my software and updating same. Today I started Norton Speed Disk. It had no sooner started than I got a blue screen error message. Only had time to read a couple lines ("Windows has detected a problem and is shutting down --") before it shut down the computer. Completely powered down! Wish I could've read the rest of the screen. Now it won't go beyond the BIOS checks at startup. Nothing but black screen after the BIOS checks. Can't get into Safe Mode, either -- in fact, it's not listed in the options when pressing F8. I'm hoping someone can give me some ideas. I'm lost! Thanks for your help.
