Solve : Windows XP x64 computer keeps restarting! RAM???

Answer»

Hey all.

Recently I have been having a lot of trouble with the computer randomly restarting. This tends to happen only when I am playing 3D games (Warhammer Online). Sometimes I get a BSOD, sometimes I do not. As for the exact error that the BSOD shows, it changes. I have had some that mentioned dxg.sys, some with the error 0x000000FC (may have miscounted 0's on that).


After MANY, many reinstalls and driver updates, I began swapping RAM around.


First, a little back story behind my weird RAM issues. My Mobo supports DDR2-800 RAM but will only read my RAM as DDR2-667. I put my girlfriends RAM in and it reads it as DDR2-800!


I took 1 stick out and it still does it. Swapped it out with the other and the same thing. I swapped both of my sticks with my girlfriend's RAM and I've had more problems... Sometimes windows will not boot and say there are missing files, sometimes Windows will boot and tell me registration keys (for antivirus) are invalid, etc. I was able to boot it up once by slowing her RAM down.

-----------------------------------------------

Does this sound like a Mobo issue? It reads my RAM as slower than it is, and won't work properly with RAM it does read properly.

Could it be a PSU issue? I've had the computer for 2 years and it's only recently started doing this... however the RAM has always been showing as DDR2-667, and it also shows as DDR2-667 on my girlfriend's computer and in my brother's computer.

If this only happens at specific times it may be a power issue - I have always tested my machines by leaving them in the BIOS to see if they restart (this eliminates software issues).

In your case though it may only happen at certain times i.e. when the system is under extreme power demands.

Try running as much software as your system can handle to see if anything happens.
What is wattage is your PSU anyway? - min of 450w is required here.It's a 550W PSU. I left the computer on overnight and had no restarting. This all seems to have started when I installed Windows XP Pro x64 instead of Windows XP Home. Does that require more power from the PSU? I'm thinking about just going back to 32-bit windows if that's the problem =/

I might also add that I have 3 DVD drives and a floppy drive hooked up. Also have a wireless card I don't use. Would unplugging them help us narrow down a power issue?Navigate to: C:\Windows\Minidump folder.
If you see any .dmp files, zip all of them, and attach ZIPPED file to your next reply.
