I've recently had a few problems with my computer, but the latest has me puzzled. When I hit the power button in the morning, the CD drives power up, the fans start, and the hard drive light comes on and stays on. There's no beep. The monitor power light blinks, indicating that no signal is going to the monitor. Nothing else happens. For the first couple of days, hitting the reset switch made the computer restart normally. Once started, it runs perfectly all day. It seems to be getting worse, because for the last few days I've had to hit reset more than once before the computer restarts. Sometimes I need to switch the power off at the wall, power up and hit reset. Does this sound familiar enough for anyone to narrow down the cause? I'm assuming motherboard, RAM or graphics card, but I don't have access to replacements to test by substitution. The mobo is a Leadtek WinFast K7NCR18D. The system is about 4 years old, except for the graphics card, a Leadtek GF4 Ti4200, a recent replacement for a dead card. (This new card ran perfectly for a couple of months before the current trouble.) I've had some recent issues with Zone Alarm and its sloppy use of navex15.vxd & naveng.vxd, but the current problem doesn't feel software-related.

I have the same problem. In the very beginning it was a matter of turning off and on the power supply and hit the Power button again. Nowadays, when I press the Power button, the computer seems to start up but the monitor stays off. The power and harddrive leds on the computer are burning the whole time till I switch off the power supply. When turning the power supply on and pressing the power button to the start up the computer, I have to wait for a couple of minutes before the computer actually starts up. The first screen on the monitor is the BIOS setup page, which indicates that the CPU speed had a wrong value at the previous boot. I simply press F10 (save settings and exit) and the computer starts normally. I think it has to do with the power supply, but I'm not sure. Perhaps someone else can give us some information about this problem?

I had a similar problem and had one heck of a time figuring it out. Here's the problem I had; PC would power up normally one day and work fine. Next day it would power up with no post, I would hit the reset, and PC powered up normally. My end result was bad ram. Initially I didn't believe it to be the ram as I ran memtest for at least a 12 hour period with no problems found. End result, however was the ram. If you have a spare, that's where I would try first based on my results. Good luck What happened to my quote

Thank you all for your help. It looks like the *ing capacitors on the mobo are *ed. Several are bulging and leaking. From http://en.wikipedia.org/wiki/Capacitor_Plague : When this happens, the capacitors no longer adequately serve their purpose of filtering the Direct Current voltages on the motherboard, and system instability results. Some common symptoms are: * Not turning on all the time; having to hit reset or try turning the computer on again * Instabilities (hangs, BSODs, kernel panics, etc), especially ones which get progressively worse with time * Memory errors, especially ones that get more frequent with time * Spontaneously rebooting * In case of onboard video cards, unstable image in some videomodes * Failing to complete the POST, or rebooting before it is completed * Never starting the POST; fans spin but the system appears dead I got all of the above. DEOS_NR1, have a look at BadCaps.net, especially http://www.badcaps.net/tips/ , and check out your motherboard. - Jason
