Need opintions on troubleshooting a computer not booting correctly

[techenthused73]

Hi,

 

This is a post for my mother's computer.

 

The computer sometimes will shut itself down when not in use.  Power settings are to never put the computer or monitor to sleep.  When trying to reboot by using the power button it takes several tries to start it up.  If it starts up then sometimes she can hear it booting into Windows (Windows 7 startup chime as it boots to desktop) but nothing shows on the screen. After a couple of tries the computer boots and she can see the desktop.  She has upgraded to new hardware/system  but kept the same power supply from a previous build.

 

My only guess is either a virus, problem with power supply, or video card or monitor.  I'll be going over to her condo this week to check it out.

 

Thoughts?

 

Old system was (1GB DDR ram, pentium DUO-CORE circa 2007, one hard drive)

New system (8GB ram 1600 mhz, i7 860, one hard drive, non powered creative extreme gamer,)

 

Both systems have a cheap non PCI cable powered video card.

could it be the gpu? 

 

can you try using integrated graphics?

If possible, bring a GPU along with you, knock out, or confirm a problem right there.

That was my first thought.

Mine used to do this too. I don't think it's hardware related but just that Windows forces it into sleep mode even though power settings are set to never turn off. I never could figure out how to turn this off, but it only happened when left unattended for a few hours.

This is an old core i7 860.  The chip does not have integrated graphics but thanks.

If anyone here is still interested.  Today I got a new Thermaltake 600 PSU and a cheap GEForce g610 (she does not game) GPU.  When I was checking things out Windows 7 in the Action Center actually logged problems with power and video card.  Thank you Windows.

 

I'm sure if this does not solve it I'll be contacted.  Thanks for the replies.
