A While ago I had some problems with my computer, I came here and got the problem solved very efficiently, so here I am again with another

I also had posted a topic for my girlfriend (a couple might remember), her computer would randomly shut down, and only AOL Instant Messenger would remain running. She had went on a trip around the time I had posted, so we could not do anything but wait until she returned. She came back, but I had forgotten to go to you guys when she did, and now I have no clue where her topic was.

She took her computer into a store to see what was up. They assumed the surge protector, or whatever it was the PC was plugged into, was damaged, because it worked fine at the store with no problems. When she got it home again, this time plugging it up straight to the wall somewhere else, it started doing it again. Upon taking it back, it was discovered that her whole motherboard was screwed up. So she got a new one, and her problem is now solved.

As for my new problem:

For some reason, sometimes when I shut my computer down, I get BSOD's before it finishes.

I have no clue what would cause it after my computer closes practically everything running, and I do have protection for my COMP (AVG Free, AVG Anti-Spyware, Spybot, Ad-Aware 07 [trial], and Comodo for firewall), and I run those regularly.

Anyone able to help me find out what's wrong?

Also, what's SVCHOST.exe? I seem to constantly have 3-4 running, and Comodo picks them up frequently to ask me if its ok to let them run or not.

Thanks again,

Imperial SVCHOST.exe is fine. A quick search on google reveals its official documentation. http://support.microsoft.com/kb/314056

Comodo will ask you for a lot of stuff unless you tell it to remember that executable is safe. Whenever something injects into the MEMORY, tries to take control of a peripheral or another program it will warn you.

Have you tried running memory tests on your RAM? Download the .iso and burn it to a disk as an image, or if you have a floppy get the floppy one. Run the test through a few times on each stick, in the slot CLOSEST to the CPU. http://www.memtest.org/

Also, visit your Hard Drive manufacturers site and download diagnostic software to thoroughly check the drive.

What fixes, if any, have you tried to resolve this issue? When does the computer shut down, is there a common factor, game, internet?

Have you tried measuring temperatures either in the BIOS or with a program like everest?

A lot more information about your computer will be needed. OS, Memory, Hard Disk, Motherboard, Age, etc.

When going inside your computer follow all anti-static measures. Not working on carpet, grounding yourself etc.

Even if it doesn't resolve the issue you should still try Cleaning your computer.I typically shut my computer down when I'm not going to use it for a while (anything from most of the day and onwards) but I tend to leave it on overnight, so that my iPod can charge, and I listen to music on my comp when I go to SLEEP ( I have an audio cord hooked from this to my sound system).

If a game needs the computer to shut down in some way, I tend to restart it, and I've never gotten a BSOD for restarting the comp (but I have for generally turning it off)

My specs:

Windows XP Home Edition (5.1, build 2600)
510MB RAM
HDD is 33.6GB total, 26GB used, 7.67GB left.
Not sure how to find my motherboard (although I'm probably about to tell you without knowing it), but I've got a Dell Dimension 2400 Desktop, with an Intel Celeron CPU 2.40GHz processor. This was purchased for me Christmas of 02'-04' (I forget which, probably '03 though)

I haven't really tried to resolve the problem, as I'm not sure exactly what is causing it. I've ran virus/spyware scans and the like, but that apparently isn't it.

When I've worked on this computer before (I had put a RAM stick in from another computer [it once was 254MB RAM altogether, put a 256 in it from the other comp] and my current CD drive which has a burner on it), I was on tile flooring, without socks on.

From visiting this site prior to my current problem, I was questioned about my Fan's speed and related things. They had me download SpeedFan, which I honestly have no clue about other than that it had shown my computer's temperature at one point. :$

With Memtest, I only have one (plugged in) CD Drive on my computer. Will that suffice?

And 2 hours later..:

I had forgotten to post this (was doing multiple things), and inbetween the time, my internet died somehow, so I turned my computer off (this always makes it work again). It didn't BSOD this time.

Could that mean anything?I don't mean to be impatient, RUDE, or repugnant in anyway, but:

Can anyone answer the questions I asked in my 2nd post, so that I can do some of the things DeltaSlaya prescribed?

Thanks.You can use MemTest 2 ways...with a floppy drive or a CDRom drive...if you don't have a floppy drive then DLoad the bootable ISO package for CDRom and use that one.
Set the BIOS to boot from CDRom first.
Let MemTest run a few hours...Alright, I'll check this out tomorrow/Saturday (being the weekend I have time lol) and post my results when I get them
