Mod Edit:  Split from https://www.bleepingcomputer.com/forums/t/643258/ - Hamluis.

 

My wife's PC has been giving random problems, such as refusing to boot into Windows (Win7 64bit), but a bit of unplugging memory and SATA cables and replugging them has usually sorted out the problem.

 

But now, when switching on, the PS starts up, the CPU fan starts up and then shuts down and starts up continuously.  The keyboard lights flash on and off with each cycle, but that is the limit of what happens.

What can I look for, as I have tried the unplug, plug routine, with no joy.

 

Thanks for any help.

 

Barry

Disconnect all drives (SATA and power connections), drop down to one RAM stick in required slot, and check for a POST, and, better yet, a display....

Thanks, I will try that tomorrow - already after midnight here in South Africa.  I have another PC with the proper CPU and a PS, but I need to drive and get it, so I may still be able to resuscitate it.  I will post my results here.

 

Sorry, Hamluis for hijacking another thread and thanks for moving my query.

I tried replacing the CPU and the PS, but to no avail.  I then used my old (Foxconn) motherboard and that was great, meaning that the Asus MB was fried.

However, getting the system running again was a bit of a job, as the drivers needed to be updated (on a machine that would not start up).

I came across an extremely helpful page (http://www.dowdandassociates.com/blog/content/howto-repair-windows-7-install-after-replacing-motherboard/) that fixed that for me and the PC is running well again.

Thanks for the help.
