By Dsaviorx77 ·
I have the in D975XBXLKR LGA 775 motherboard, and its been giving me problem. Sometimes the comp will turn on but when i turn it off, it wont turn back on. For this reason, i have to disconnect the SW power wire (swith on wire) then put it back on the motherboard in order for me to turn it on again. I was wondering if it is the wire or my motherboard? please help!!!

i had this similar problem when i got a new case, and it happened to be the boards was actually shorting out on the case when i removed it and turned everything on outside the case it works fine, i then touch some no conductive, thin foam and also go extension mounting screws to mount it back in my case.

Soft Switch

by LarryD4 In reply to Motherboard or is the swt ...

The soft power off switch your referring to is a pretty simple design but could be your problem.

You can try www.cyberguys.com to see if you can get a replacement.

But I would suggest checking power ratings, overheating, and even a power supply issue as possible causes.

More likely to be the Power Supply here

These particularly the No Name ones can be flaky after taking a surge from the mains.

Similarly a good PS can do a similar thing after taking a Big Hit from the mains and needs to be disconnected to allow the system to be restarted.

Depending on what you want out of a PS the protection to save the hardware in the event of a nasty happening or the cheap PS that just works and offers very little to no protection of the internal components.

I've seen the results of a High Voltage Overland Transmission line coming into contact with the Low Voltage Mains with a No Name PS the entire unit was dead and everything was lost requiring a complete replacement of everything and all the data lost. Then with a Good Brand PS when power was applied the fans ran LED's lit and you get a message that the Monitor was disconnected. Replace the PS and it worked perfectly for another 3 years and everything was intact.

Not a test I would really recommend to check out just how good a PS is but it's nice to know that you have that level of Protection when the worst happens.

OH check the Plastic cover on the Power & Reset Switches they can occasionally stick with some less than perfect molding or when the unit sucks in a lot of Dust I can remember spending hours on one unit because the Reset Switch was sticking just slightly would work all the time when it arrived after being jolted around in transport but when sitting on the Bench after pressing the Reset Switch it became very unstable. Turns out that there was a ridge in the Plastic of the Reset & Power Buttons that had caught a lot of Dust in and this was causing the problem. After filing the plastic down smooth the problem was gone.
