Hopefully, someone here can help with this problem.
I am running an older Dell XPS 700.
Basic specs:
Dual CPU Intel Pentium 4 3.8GHz
8 GB RAM
Windows XP Pro (SP3)
Basically, when powering on, all fans would spin, then everything would shut down after a couple of seconds. It never lasted long enough for the monitor to even display anything. (It would show "on" lights for a second, then display "Power Save Mode", then the PC would just quit working.
I replaced (and upgraded) the power supply. At that point, I could get it to almost boot (BIOS loads, Windows begins to start), but then the monitor would go into to power save even while the fans were still spinning and the computer sounded as if it was still running. I disconnected the dual graphics cards one at a time and eventually found one was bad. The computer will boot and run with just 1 of the 2 cards in. I did have to boot to the Windows disk in order to repair some files, but was able to get the PC running. It will run absolutely fine, Windows can auto-update and auto-restart with no issues. I can manually reboot with no issues.
HOWEVER, sometimes, after shutting down, the computer is hard to get running from a cold start. I can power it on, all fans spin up, Windows starts booting, etc. But then it will shut down. Sometimes, it completely powers off. Other times, the fans continue to spin and all components seem to be running, but the monitor goes into power save and shows no activity. It can take several attempts to get it to completely boot.
Once it has booted, however, it runs without any issues. I can leave it on for days with no problems, even when Windows updates and restarts. I can can restart myself with no issues. The only time I have trouble is when I try to start it up from a "cold" state.
For instance, today the electric company replaced our meters without warning and shut off power long enough that even the UPS failed, so when I got home, there was a notice on the door and the PC had been down who knows how long. I had to attempt to boot it 6 times before it would run. Once it's up, no problems.
What could cause this intermittent issue? Power supply is good, fans are good, RAM checks out OK, no viruses/Windows issues.
Could it be the other graphics card? (I wonder due to everything seeming to still run with no display, and it's NOT the monitor.) If the card is bad, why would it work ok once started, and not while trying to start? Previous experience with failing cards has led me to expect performance issues like graphical glitches during gaming which I am not experiencing at this time. Would 2 cards AND the power supply fail at the same time? Could a failing power supply screw up both cards?
There were definite power supply issues before replacing. It would not run with everything disconnected. It would try to start, but immediately shut down (within 5 second). After a shut-down, the only way to get it to even try to start again was to disconnect the power cable from the power supply, then replug it in (hitting the power button did nothing). All fans spin once computer tries to start.
I'm obviously savvy enough to pull and switch graphics cards, test fans, disconnect auxiliary devices, and to replace my power supply. But I'm not THAT savvy with hardware. Any help is appreciated, but beyond the basic unplugging and replugging in, I will need some pretty detailed instructions on how to accomplish anything more complicated. I'm willing to give it a try though, as the computer is out of warranty anyway, and Dell is NO help at all. I refuse to pay to talk to someone I can't understand, and who wants to sell me a new $300 power supply (the only way I can be sure it's compatible according to them) before they will even TRY to troubleshoot my issue.
