Hi,

I've been having this trouble for a while and its driving me insane. My computer resets by itself. It may be on for a few hours or a whole day, down to a few minutes. Then it resets. It would come back up fine but now it resets and gets stuck at the windows xp boot up screen. Then resets again. It will then reset and ask me how I want to boot up windows, I choose last know good config and it resets again. Its just keeps looping. If I keep it off for 30 minutes then Ill boot it up and it goes back to NORMAL. It doesnt matter what Im doing, I could be playing a game or just let it sit idle and same issue. But more so when playing a game or running mutiple programs at the same time. Ive built my rig almost 4 years ago.

So far Ive taken out two sticks of ram, cleaned out all the dust from the inside of my computer and made sure everything was fitted properly.

Also Ive turned off indexing and I do get bsod and these two messages so far since I disabled the option of automatic reboot on a bsod.

specs -

windows xp sp2
120 gig seagate harddrive
3.0 ghz p4 cpu
2 gigs of ram (1 gig right now at pc3200)
ati tv wonder pro
generic sound card from best buy, dnyex i think its a 5.1 channel one
Nvidia 6600 gt 128mb

I also have a thermaltake 500 watt power supply

I dont know what else to do, please help .Download SeaTools from the Seagate site and test the hard drive.

Download Memtest from www.memtest86.org and check each stick of RAM for an hour or so individually, then all together.

Both of these run before Windows loads, so you can eliminate Windows as a source of problems at this point.

Take the side panel off and make sure all fans are turning and then leave it off and point a fan directly in there.

Post back your results. where exact do you download from? (the memtest)1. MemTest86 "Home" site is: http://www.memtest86.com

There are links on the left-hand side of the home page. Left-click on "Free Download". The latest version is "MemTest86 v3.4".

You choose between downloads to create a bootable floppy or CD-ROM.


2. Boot Floppy. To create a bootable MemTest86 floppy from a Windows or DOS environment choose:

Download - Pre-Compiled Memtest86 v3.4 installable from Windows and DOS
http://www.memtest86.com/memtest34.zip

Within the downloaded zip file there is a "README.txt" that is also the USERS manual for MemTest86. I've found that I can read it in Microsoft Word, but in order to read it through "Notepad" I have to open it in Word and then save it out (possibly as new) as text file. Not sure why.

ADDENDUM: Twice downloaded, unzipped, made floppy, and attempted to execute "v3.4" of MemTest86. It loaded and started but crashed with an "Unexpected Interrupt - Halting" after only 19 seconds of execution. This happened repeatedly on a system without any history of memory errors. Apparently, it is a problem with this version of the program as I can still successfully run "v3.3" on my old Pentium II 350 MHz system and have successfully run "v3.2" in the past. If you experience program failure, suggest you fall back to version 3.3.


3. Boot CD. To create a bootable MemTest86 CD-ROM, I would choose the following:

Download - Memtest86 v3.4 ISO image (zip)
http://www.memtest86.com/memtest86-3.4.iso.zip

Well I did a test on my hard drive and it said everything was fine.

Now when I did the memory test, I tested each stick individually.

It would reset every time I did the test. Didn't matter which slot or what stick of ram I was using.

So.....thanks, the memtest.org is some commercial site.
1. Hard Drive. Whose test did you run? What version? What media did you boot from? Which test function(s) did you run (i.e., what did you test)?


2. Memory. Whose test did you run? What version? What media did you boot from? Which test function(s) did you run (i.e. default test settings or specific test functions)?

How far did the testing get? Were there any memory errors reported?

Looking ahead to your answer, I decided to test drive MemTest86 v3.4 using default settings on my old Pentium II 350 MHz system with i440BX chipset. Twice downloaded, unzipped, made floppy, and attempted to execute "v3.4" of MemTest86. It loaded and started but crashed with an "Unexpected Interrupt - Halting" after only 19 seconds of execution. It did not "reset" HOWEVER. This happened repeatedly on a system without any history of memory errors. Apparently, my problem is with this version of the program as I can still successfully run "v3.3" on my old Pentium II system and have successfully run "v3.2" in the past. If you experience program failure, suggest you fall back to version 3.3.
Good info from Dahlarbear here...i also experienced problems with V3.4 as well and reverted back to an older version. Problem solved.1. I used westered digital data lifeguard 1.9b, I forgot I SWITCHED out my seagate hardrive a while back.

2. I went ahead and used 3.3v of the mem test. Booted w/ cd and still reset. Again doesnt matter which stick I use or slot. I have 3 slots.

Even with a fan blowing, doesn't help.

I'm afraid I'm going to have to buy a new motherboard.
