Computer Specs Windows XP Athlon AMD 1333mhz Gainward Geforce Ti4200 Graphics Card Asus A7V133-C Motherboard 512 SDRAM 80GB Western Digital 7200rpm Hard Drive Soundblaster Live DVD & CD Writer 350 watt power supply Hollywood Plus Decoder card Ni200 Modem Lately during gaming, usually Battlefield 1942 or Operation Flashpoint my PC has been resetting without warning. If I am not playing a game and instead surfing the net the PC can just freeze. I have done countless searches on the net and overheating is suggested 9 times out of 10. However... I investigated the power supply plug to the motherboard and noticed that the connector plug (plastic surrounding the pins) which is plugged into the motherboard had burn marks on and around 3 separate pins. Thinking this was the power supply going on me I purchased another power supply only to find within a day the same problem was occurring with burn marks appearing on the new supply. I have noticed that the power supply connector doesn’t plug all the way into the motherboard slot so is it possible one of the connecting pins (bent?) on the motherboard is causing it to short circuit? Normally the plug should utilize the hook to snap it into place. I have checked the temperature of the motherboard and cpu and they are both way within normal range, however I’m not sure that has always been the case as it can get pretty hot after a muggy night. Can anyone help me to pin point the problem so I don’t go out and buy another motherboard when it could be a simple explanation. Maybe somebody has seen a similar occurance? I really appreciate any suggestions. Cheers.

if burn marks are on your power supply, doesn't that mean your power supply has a problem? I bet your restarting problems are caused by power supply. What are the FULL specs of your power supply including 3.3v and 5v combined ratings

Looks as though another guy had the same problem a while back. What happens is the smaller psu of 300 is overloaded when a new component is added. In this case a gf ti4200. The ATX burns out and plastic that melts pools in the P1 part of the motherboard. When I replaced the psu with a 350 it couldnt make the connection properly due to the build up of burnt plastic in the slot and that too overheated. Seems a new mobo is the option to take, or try to dig into the P1 and get the burnt plastic out... Pictures of exactly the same problem (even down to burn locations) can be seen in this thread. http://forums.overclockers.co.nz/showthread.php?s=&threadid=4232&perpage=15&highlight=superflower&pagenumber=2
