Why can;t I enjoy my PC all the time?

By mallmill13 ·
I'm the only user of my Shuttle SFF WinXPSP2 PC that I built a year ago. It's working great-have AV et al-no malware, no rootkits. My problem? When I shutdown my PC and turn off the surgebar switch, I don't know whether my PC will boot next time I try! Sometimes it posts and boots; sometimes the power and HDD lites are on but no post and no boot; sometimes neither the power lite or HDD lite come on and then I suspect power supply failure. I swear I do absolutely nothing to my PC between unsuccessful and successful boots! I always wait at least 15 minutes between tries. My Bios boot order is CDRom-HDD-Floppy. No CD or floppy is in its drive. When an unsuccessful boot occurs, my 19" LCD Proview monitor remains dark so there are no error messages. I'm open to suggestions, hints, or solutions.

I neglected to point out that my problem began only 3 weeks ago; anyhow I wouldn't buy a Dell.

I've seen similar troubles from just about all types of machines, mostly home brews. The most common trouble is the connectors that are provided by the case manufacturer don't always match up with the connectors on the MOBO. some have an "always on" provision and some don't. Some have turn on functions at the keyboard, meaning at least the 5 volt part of the power supply be on, thus it is not really off unless you actually turn off the switch on the back of the unit. That means if you turn on the unit from the back, you get a flash of the lights but no power up. Then a keystroke will start the boot up. Check the BIOS for these functions. The reason for the change?? Who knows, I've got one that works the same way, and found it to be a failing hard drive that would keep the P/S from starting properly, thus no boot, Bios or any display.

You say that you turn off the surge strip that supplies power to your PC.

While turning the strip off increases protection against surges on the power line, turning the AC power off may be at the root of your problem.

What I suspect is wrong, is that you have a weak CMOS battery. When the CMOS battery gets weak enough, it can cause the BIOS to lock up and not get through the POST process.

When you turn an ATX style PC off, some power is still supplied to the motherboard. Among other things, this power keeps the CMOS settings and real-time clock running.

When you switch AC power off to the PC, the system is forced to run the CMOS and real-time clock off of the back-up battery.

The coin cell batteries used for CMOS backup can last for up to 10 years "if" the PC is usually left with power on. When you turn the AC power to the PC off, the running life of the CMOS battery is significantly shortened.

To test this, try leaving the surge strip switched on and see if the PC now powers up normally after it has been off for a while.

If so, change the CMOS battery.

When your PC is back up and running have a look at your eventvwr for any errors, Change your CMOS battery, run chkdsk on your system, go through logs on your PC see if you can find some sort of an answer, Change power supply, Open the box and have a look inside see if all cables connected securly, Clean the system and so on...
If it happens 3 weeks ago try to think if there was some sort of power surge, You installed somthing...

Your problem sounds similiar to what I've seen after installing a wireless keyboard. If your keyboard is wireless try connecting a wired keyboard before powering up.
