Reboot Reboot Reboot why does it keep rebooting.

Apr 11, 2004 12:29PM PDT

We started with a 400Watt power supply
3.2GB AMD Athlon XP Processor - standard heatsink
1GB RAM
120 GB WD 7200 HD
ATI All-in-Wonder 8500
Firewire PCI Card
SONY DVD
SONY DVD-RW
Standard Floppy
ASUS Motherboard
OS XP Pro sp1a

Bad Floppy replaced
Power supply upgraded to 450Watts
Heatsink upgraded
Memory replaced and tested

Currently the system is running under a load 43degrees C. No load 28 degrees C.
Voltage stable per ASUS probe

When attemmpting to run any processor intesive program after about ten minutes the system hard reboots. If the system is running under no load the system will run all night. Running intesive programs like EverQuest or SETI@HOME the system reboots. Running Word or a standard screen saver is not causing reboots. The heatsink was replaced to solve an earlier heat issues. The power supply was upgraded due to a thought that we might have a power issue.
ANY THOUGHTS I am tapped out. I have never had issues like this before and I have been doing this for seven years.

HELP??????????

Re:Reboot Reboot Reboot why does it keep rebooting.

I had a similar problem which I think was caused by putting my Copper Gigabit network card in the first slot which shares resources with the on-board video. I moved the card to slot 3 and no more problems. Remember video intensive operations sharing IRQ's with another intensive operation such as over the Internet is not a good mix. Try not to use the slot sharing the video resources unless you run out. Then, put a low use card in like for USB printers, etc.

Here's what I suggest

1) Are all your drivers current? Make sure you have all the latest drivers.
2) Is your BIOS up-to-date? If not, go to ASUS's website to download and install it.
3) Next, make sure the PSU you have isn't a generic $20 one. They're usually bad, and believe me, I know. Just because it says "450W" doesn't mean it can run at that capacity. Make sure it's from a well known and trusted company like Thermaltake, Vantec, PC Power & Cooling, etc. Look at reviews of current PSUs. I'm currently running a Thermaltake PurePower 450W PSU w/ Active PFC. I get much less rebooting now, especially since I originally had a 250W L&C PSU (it worked longer and better than the cheapo 400W PSU I had bought; I still have yet to hear from PowMax...)!!

Also try the other guy's suggestion as well.

i had a similar problem i resolved it by replacing my ram not all though i would take one out put a new in and so on so on till i found the one that was causing the problem might not help much but it is worth trying out hope this helped cause a bad memory module can do strange things

As stated in the orginal post all the RAM has been replaced and indpendently tested in other machines.

To echo an earier post. I haven't had this problem, but I
do know my MOBO-ECS-suggests you not use PCI slot 1 unless necessary becaause it can interfere with the AGP slot. chuck

UPDATE : Reboot Reboot Reboot why does it keep rebooting.
Apr 12, 2004 8:30AM PDT

Last night I pulled the Fire wire card unplugged all the drives, save the harddrive, and replaced the video card with a Radeon 7500. The system ran EverQuest for 20 minutes then rebooted. This is a record for uptime for this machine. I still would beleive that it must be the motherboard as the only load on the 450W PSU was the motherboard, 3.2G AMD processor, WD 120GB 7200rpm HD and Radeon 7500 video card. Two standard case fans and the CPU cooling fan yeilding about 20W of use I think any thoughts????

Notes and trials.
Apr 12, 2004 8:38AM PDT

1. Another user had decided to not use any heatsink tape or compound and was writing about what you were writing.

2. Try is with just 1 stick of RAM. Then the other, one at a time.

3. The BIOS must be current.

4. Item #3 must be current.

5. Item #4 has to be correct.

6. Try all the BIOS DEFAULT and SAFEST values. Try the FSB at 100 or 200 instead of 266 or 333... Move the AGP to 1X.

7. The lowest number of parts please.

8. No pests please. Read http://www.doxdesk.com/parasite/

All the above replies are wonderful examples of the time and effort so many people have put into solving the same sort of problem they've also encountered. Other than your reference to the programs you were running revealing that you're running MSWindows of some flavor keep in mind it's Windows that's at the heart of your problem. I don't mean to start a flame war over which OS is best but in ten years of running Linux I have never seen the problem you mention unless it was a hardware (definitely not software) problem. I have seen it many times especially since XP came out and most of the replies you've received have at one point or another been the actual solution to that problem. Which one is your solution is hard to say. Just 2 days ago my one and ONLY Windows pc started doing the same thing. Restoring the security, sam ,system and software hives (didn't touch default) got it back on it's feet but you need to be able to get at the filesystem to issue some command line stuff to do it. NTFSdos is the one tool I know of that let's you accomplish this on an NTFS system. XP should come in OEM systems as FAT32 as, for most people, the added security of NTFS is a moot point. One can always convert to NTFS if one wants to but the option of going the other way is not built into Windows and I have had ZERO success with Partition Magic converting NTFS back to FAT32. Good luck.

I gave up trying to solve this type of problem on AMD equipment after going through seven different AMD motherboard and AMD CPU combinations.

My solution is very simple, Buy a genuine INTEL motherboard and an INTEL CPU. In fact Everquest will even work fine with the new INTEL Extreme II onboard graphics on the Bayfield boards. I also recommend going with an INTEL HT CPU and avoiding the Celeron.

If you want to improve graphic performance use DDR400 RAM and minimum 512MB, 1024MB recommended.

I also tend to lean towards the NVIDIA FX range of graphic cards as they tend to be affordable and do not sacrifice image quality for extra frame-rate.

If however you insist on the AMD equipment, I suggest fitting an array of cooling fans on the side of the case ... this worked for two AMD fanatics that join our LAN party. This has still not fully solved their problem however as their machines still lock up and reboot after about three hours of C&C Generals.

I might be prejudiced, but my prejudice comes from personal experience! Wink

As you noted, you seem to have checked pretty much everything. Your system is running at the AMD recommended temp., so I suspect it's not a problem adding another fan would fix. Since you mentioned your OS and no other software, we can't analyze this. First I would check my CPU temp in the hardware area, and look for virii and parasites in the software area. Good luck. chuck

Do you have a fan on that 7200rpm hard drive? You MUST have a hard drive cooling fan because those hard drives will run MAD HOT. I began getting this problem too with my system, then I saw that my hard drive cooling fans died. I oiled the fans, and now it doesn't go over 29 C at full load and is rock stable. Make sure all your fans stay oiled!!

I had a similar problem at one time, what I ended up doing is replacing the motherboard and it solved the problem. you have 2 different dynamics happening under any electronic device, " at rest " and " Underload".Also, any time you have a product that is mass produced, you have a certain number that is faulty.
