My deskop computer is having some trouble. It's having some strange symptoms, and does one of four things whenever I start it.

1) The screen stays blank. I've had this problem before and had to replace the motherboard. The motherboard I have now is about 2-3 months old.

2) After the motherboard logo appears, rather than loading the setup, the screen stays blank other than a blinking underscore at the top left corner of the screen.

3) The setup begins to load, but gets stuck on "Verifying DMI pool data........."

4) The computer performs the setup, but right before windows loads, the bluse screen appears.

If I leave the computer on for long periods of time, I have no problems with it, and the problems very rarely happen when I restart it. They only seem to happen when I power on the computer after it has been completely turned off. Any ideas? Thanks for the help!

It sounds like a weak power supply possibly complicated by dirt on fans in the computer, it's that cold startup which requires more power or amperage to get everything running. You can try cleaning the inside of the computer, another remedy(temporary) is start the computer and as soon as it stalls, hit the reboot button if you have one or hold in the power button to shut down and then restart right away.

I had the same problem when the room is too cold.

No luck so far but thanks for the suggestions. It's been 2 days since it's run properly. I'm going to reformat it this weekend and see if that helps at all. Any more suggestions would be greatly appreciated. Thanks!

If windows is corrupt and your boot files are damaged, it would stop at the same place, formatting and reinstallng will not fix your problem.

Many power supplies are underpowered, but they are cheap and easy to replace. If you blow your fans off while you have the case open, hold them so they don't spin. That can throw them out of balance. Yeah, I know it makes a cool noise, but I usually try to resist.
And never ever use a vacuum to clean near circuitry inside the case. They cause hella static.

Are the boot files located in the hard drive or somewhere else? It seems to me that if it's the hard drive then reformatting would work unless the hard drive is damaged. If the boot files are located in the motherboard then it definately wouldn't work.

I'm not saying I dont believe you. It says "This issue is caused by the hardware." I'm just trying to find out what hardware that is i.e. motherboard, hard drive, etc.

the motherboard and cpu will be the hardest to check out

visually inspect the mobo for bad capacitors

first do what I said and make sure the computer and fans are clean

next check your voltage rails(bios) or software, make sure they are within specs

try disconnecting any extra non critical components from the power and see if that helps

go into bios and disable any fast boot option to see if the memory count proceeds w/o error

use memtest to check the memory

run a hard drive diagnositic

Mine got to where I had to wait for it to spontaneously reboot several times before it would hang on and run. It got worse and worse until I replaced the HD. It's run fine for two years with no problem like that again. The old drive worked fine for data storage, at least long enough for me to copy My Docs and my Desktop folders over to the new drive.
