Gahh!!! I have been battling my computer for a week or so now and seem to be in a stalemate. Here's my situation: I have a new Asus A7N8X-E Deluxe board, with an Athlon XP2600 processor and 512MB of PC3200 RAM. My FSB is set at 333MHz (can't get it to be stable at 400) and all my memory timings, voltage and such are set at default. Here's the issue: Out of nowhere in high and low loads, hot and cold, the computer will restart for no reason at all. The processor runs around 45-50C idling, and 50-60 when it gets really hot. (Yesterday it was 100 degrees outside and very hot inside my house, and the processor got up to 62C, the highest I've seen it). This should be well within the capabilities of the processor so I don't think over heating is the issue, though it is running a bit hot. I've flashed the BIOS to version 1008 (there was 1009 and 1010 but they were pulled) and it still happens. I've updated drivers for the board and it still happens. I've reinstalled XP once and it still happened. I've reseated the RAM and moved it to a different slot and still happens. I ran Memtest on the RAM and it said it was fine. I'm at my wits end - what else can I do??? Bad board? RAM? Hard Drive?? I've prowled Google for an answer with no luck. Any ideas would be very very appreciated!!

If you do the following steps, XP will display an error message instead of rebooting. It might give a clue to the problem area. 1. Click Start, and then right-click My Computer. 2. Click Properties. 3. Click the Advanced tab, and then click Settings under Startup and Recovery. 4. Under System failure, click to clear the Automatically restart check box. 5. Click OK, and then click OK.

Another thing to check would be the power supply. New systems (Athlon & P4) pull their power from the +12v rail...before these CPUs came into being, the main CPU power rail was +3.3v. Check the label on the side of your PSU & see how amps are on the +12v. As a rough check, add up your components & see what you come up with... CPU = 6-10 amps (depends on model) motherboard = 0.3 amps hard drive = 2 amps each CD/DVD drives = approx 1 amp each cooling fans = 0.25 amps each http://www.firingsquad.com/guides/power_supply/default.asp "If you can read this, thank a teacher" "If you are reading it in English, thank a veteran."

Im running the same board with a 3200 processor and 1 gig of 3200 memory with no problems. I had problems trying to run CL2 and CL2.5 modules and had to go to CL3 to get things stable with no problems. Sounds to me like a hardware issue on your setup. What kinda video card and other hardware? Memory is very crucial on the higher performance setups. Clear the restart tab the other poster talked about and check the box send a administrative alert. Are you getting any bluescreens with stop error numbers? May God forgive, and bless the United States.

i'm not convinced about the ram, the same thing happened to me and it was bad ram that caused it. I couldn't figure it out for ages and just changed the ram and it worked. can you borrow a ram stick to test that? :D bla bla bla

I'm having the same issues here's my set-up: Asus A7N8X-E Deluxe AMD Athlon XP 3000+ @400 fsb Kingston Valueram 1 GB Dual Channel Kit @ PC3200 NVidia GeForce4 Ti4200 w/128 MB Creative Soundblaster Live! 5.1 Sound Card Western Digital 60 GB 7200 RPM 8 MB chace 16x DVD 52x CD-RW 2 80mm case fans, Thermaltake TR2-M1 Proc heatsink/fan Installed all correctly, trying a different RAM configuration, start to do anything CPU intensive get a restart, winblows says it's a device error, that the drivers aren't OEM drivers and could cause instability but thats a bunch of bull cause they are correct drivers from the companies. another error it gives is that it is a deal with the RAM and suggests i run their RAM checker, haven't done that yet, don't know that i will. just blew $50 on a new 500w psu with 20A on the +12V rail, still restarted, trying the new RAM config(did have the 2 512 sticks in A1 and B1, trying them now in A2 and B1, like the manual says). will let you know, my guess is it is a RAM problem, but i really don't wanna get new RAM....

Fixed it, for some reason having it in the A2 and the B1 slots solved the problem, hoped this helps someone else out there
