Setupdd.sys Could Not Be Loaded Error Code 4

Posted by rajascientist Tuesday, December 29, 2009 0 comments

Recently my friend had a problem with his system. The complaint was with the power supply , when turned there is no response in CPU . I removed the SMPS and after inspecting for a while , we found that the problem was with SMPS and we decided to buy new one instead of repairing it.

After connecting the new SMPS I switched on the computer but we found abnormal signs in monitor display , it flicked ,also many dots and vertical line were seen in the display. Ignoring that we proceeded but unable to boot in all modes including safe mode.

   We once again checked for all connections and again restarted the system but there was no use.
So we decided to install new XP but that too ended in vain. While booting from cd we had the following error Setupdd.sys Could Not Be Loaded Error Code 4    , we found out that the problem was with RAM and I removed it and cleaned it after inserting ,same problem occured, so we replaced it with new RAM now system works fine.

SYSTEM SHUTDOWN DUE TO THERMAL HEATING

This was the message I got few months ago whenever I started my PC , sometimes suddenly my PC will go off and When I restart again the same message appeared.

I thought I would have over used my Computer but thats not the problem I know, because system can be used continuously throughout the day .

I removed the cooling fan and heat sink placed directly above the processor and cleaned it.

Fan was working good, heat sink was cleaned and now its free from dust. I cleaned the heat sink with cycle pump. Now assembled everything back in to its position . Again I got the same message .

This time I removed CPU fan , heat sink also the processor beneath.

It was difficult to remove the processor, the heat sink compound was dried and it was difficult to remove the processor.

Heat sink compound is a white paste like substance applied over the processor and at the bottom of the heat sink. It is mainly used for cooling and can be obtained at local shop.

I bought a new compound and applied it . But when started my PC it ran good for a while again it stopped, showing the same message.

Now I removed all the wire connections from SMPS and checked the wires . Finally I found the culprit.

It was a four pin from the SMPS yellow, black wire i.e, 12v wire. The wire end was blackened.I opened the SMPS and rectified the fault now My system is working fine.
