 Computer randomly restarts Post a Reply  
From: Paul on 06/27/2002
Dual operating - WinXP & 98 - random restarts in both.
Motherboard MSI K7T266 Pro2 with AthlonXP 1800+
Video ATI Radeon 8500

Random restarts occur at various intervals (as though the 'reset' button has been pressed)

The timing is extremely random (from starting - after 5 mins, after 5 hours, after a day).

Sometimes get just one restart then hours of use and sometimes get to the point where the computer will not start but just keeps restarting continuously during boot.

Finally, I removed the Radeon 8500 and replaced it with my old Rage card; the 8500 I put in a second computer (Asus K7M + Athlon 600). Three days later both machines are fine.

I'm suspecting a power supply problem as the Rage card has no fan and draws less power.

Or do the K7T266 and Radeon 8500 not like each other?

Help would be much appreciated.

I had my computer built for me about four years ago; AMD athlon processor, I think it's a 750mhz...anyway, a while back I was playing a game when my computer shut off and would not turn back on. I took it to a computer repair place and they told me that lightening had ran in on my power supply and shorted it out. I pointed out the fact that it had not rained for a few weeks (dry Alabama summer) and they said "Oh no, we had some lightning". So they replaced my good power supply that had a fan for a little crappy one without a fan. They did not inform me of this change, and I began to see trouble with my computer overheating and randomly rebooting, mostly while playing games, downloading music, or burning CDs. Sometimes just while surfing the net, though. Well, I decided maybe I needed to make sure there was no cat hair clogging the fan, and to my surprise when I opened the case there was NO FAN in sight. By this time I had probably done all kinds of damage to my computer components, (the computer place refused to fix it, by the way) and now I am stuck with a computer whose monitor will not come on anymore. When I turn on my system, the cpu's fan can be heard, the disk drives all open fine, and the hard drive can be heard whirring, but there is no BOOP or BEEP sound like there used to be, and the monitor's light will come on green at first but then immediately goes yellow as if it is asleep or hibernating. I made sure the video card (NVIDIA riva TNT, I believe) was in good and tight; nothing else seems to be wrong. Could I have burnt out my video card? Or are more sinister forces at work? If ANYONE has any hints, please reply here. Or if anyone could recommend a good computer self-help website, that too would be appreciated. Or a good therapist. This is driving me nuts. I think from now on I will buy computers only rather than build.

I have a system based on a GA-7ZXE motherboard which is stable and happy. The moment I put a hard drive, CR-ROM, CD-RW whatever on the secondary IDE port, it reboots at random times. Most definitely noticeable when trying to back up from one hard drive on Primary IDE to a hard drive on Secondary IDE.

Went through learning curve with CD-RW on secondary IDE. Had two hard drives on primary IDE. Thought the CDRW hardware was up the creek. Eventually stripped down to the HD and CDRW on the Primary IDE and it stayed stable. Forgot about the problem until recently when I tried to upgrade hard drive. Hooked the new drive on Secondary IDE to copy everything over, and system started restarting again.

I read through the posts, and it seems no one paid too much attention to the post about directx 9. I did the right thing and thought i should upgrade, I might get a slight performance increase or something, as I'm only running a Duron 800 at the moment. But Direct X 9 is very flawed, it will cause your computer to restart, or worse, shutdown at random or processor heavy tasks. And as for uninstalling it, you can't click a magical uninstall button, you have to delete every single file associated with it, and reinstall DirectX 8 before restarting. It's a pain in the arse yes, but its worked for me. For those of you who haven't discovered Linux, what the FREAK are you all waiting for??

Hah, it seems like everybody is having problems with the Radeon Cards. Yeah, I have a GeForce 4 Ti 4200 (128MB DDR) and I'm having the same facken problem. It is very annoying and I don't know what to do about it. I installed every possible update related to all of my hardware. I called Microsoft and talked to some dude and he acted like this isn't a known problem. I asked for his manager and he said that this is a highly known problem and it would be fixed in some future update. That was four months ago if I remember right, and my computer has restarted...at LEAST once a week. If anybody knows what I can do, please e-mail me a chucklesjh@aol.com, thanks.

Remember that if there is no video card driver for XP, the card may only work on WIN 98 SE.
The only other option with XP is to override the install by using administrator rights and install the win 2k driver.
However, unless msoft creates a signed driver for direct x 9 and your video card, it will cause conflicts in XP.

I began having this problem after I installed msofty direct x 9.
I have an agp video card. I redid my system and installed media 8 and direct x 8 only, and guess what?
No more restarts.
So I did some investigating and found out that Microsoft purposefully has not written signed drivers for most AGP Video cards under direct x 9.
Just another lovely aggravation brought to you by Bill F*****g Gates.

AAHHHHHHH!!!! I am having the same problem. 400watt power, chaintech mobo, 40GB HD, ATI 9100, AMD 1700+ Overclocked to 2.32GHZ, Large Chieftech case with lots of cooling SLK-800 heatsink. Microsoft error report tells me its a graphics driver conflict, but I have installed numerous upates from ATI.com and have had no luck. Random freezes and restarts during games like Halo. This is so frustrating and I don't want to have to buy a new graphics card. Can anyone give me any suggestions?

Thanks

I have that same damn problem - the random restarts. I've tried a Radeon 7500 (less restarts), several sticks of 512 RAM (my choice pick is Crucial RAM), and 2 western digital HDs. I can't figure out what the piss is going on with my computer.

There are too many reasons thatr an cuse the random restarts:
1. IRQ conflicts
2. Video card memory
3. RAM
4. Bad power supply
5. Damaged mobo

It's hard to figure out what's going on.

I'm never going to build a computer again.

I'm having a similar issue and since a random reboot can be caused by just about every component in a computer I have been left stumped for about 6 months now. I do believe I have the issue narrowed down, but not sure if a resolution is possible. Here's why. I have had the random reboot issue since I first built this Machine. I replaced the following parts in this order:
Power supply (from 300w to a 400w)
cooling fan (upgraded to a themaltake volcano)
IDE Cables
CD-RW (from MSI to Benq)
Hard drive (from a 10 and two 20s to a 40 and one 20 to a single 160)
Video Card (from 128 MB GeForce to Radeon 9100)
Motherboard (from MSI to GB)
RAM

and still I have the problem...
I noticed that most of the time reboots were occuring when more than one drive was being accessed at the same time (ie. burning a CD, copying data between drives etc.) After swaping everything listed above, I am left with one original part in this PC... the CPU. And from many of the "randon reboot" posts that I have perused, AMD processors seem to be in the overwhelming majority of aflicted systems (aside from celeron). Additionally, a wide variety of AMD CPUs have been listed. which makes me wonder if replacing the CPU will fix the problem.
At this (most frustrated) point, I am inclined to believe that my CPU is the problem and more specifically the way it handles IDE transactions. my current system spec's like this:
AMD XP 1500+
Gigabyte GA-7ZXE (with updated BIOS)
infineon 512 MB
ATI Radeon 9100
maxtor 160 GB
JGE 400W PS
Acer\Benq 52x32x52 CD-RW.
and one chasis fan

and to make this post even longer:
I use all the most up to date drivers I can find, I do NOT have a floppy drive and at the moment I am not overclocking. I am using windows 2K with all the critical and recommended updates.

Any one else notice the reboots during IDE calls?

I have the same prob... I just bought the Radeon 9200 SE PCI, and I get the restart problem. I got the new driver form ati.com and it still doesn't work.

I changed my memory sticks, I ran DriverCleaner and still get the error ..

SOMEONE HELP ME!!!!

Well, I've ran into this problem on my current system running a Radeon 9200. Its actually a driver issue. You'll notice if you download the current Radeon Drivers the Catalyst ones, you shouldn't have that problem anymore. Its a very common issue with the radeons and Fury cards.

I've had this happen alot and it was driving me nuts, grabbed the new driver and presto no problems.

I figure if you have a decent power supply with good amperage on the +5V and +12V you shouldn't have any problems, also if you have a decent CPU Tempurature, AMD's between 40-55 degrees celcius, or on an INTEL P4' probably below 45 is good.

Then your last resort is to grab ATI Video drivers. There was a known issue that the driver corrected.

Hopefully this info helps everyone

(P4 @ 1.7Ghz, 512 RDRAM, ATI Radeon 8500LE, WinXP Pro SP1)

My problem is similar to Paul's. After reviewing numerous websites regarding random restarts, I've noticed the most errors have occured to those who used ATI graphics cards like ours and had fairly low-rated power supplies and undercooled systems. (I'd never heard anything about those capacitors but...) When I used this 8500LE in my older Athlon 1.1 system, DirectX games would freeze after minutes, sometimes even seconds. In this newer Pentium 4 system, games run just fine but after I upgraded DirectX from XP's native 8.1 to version 9, the computer restarts at random during playback of videos in Windows Media Player (or Kazaa, anything that will view MPEGs and AVIs). It frustrates me when this happens several times in an hour; take note that restarts don't occur more often at later times-- they happen anytime during videos only.

The only suggestions I can make are to double-check that your power supply is at least 350 watts (more is required for today's games) and you have adequate cooling. (Might want to look at a Thermaltake case-- they have tons of fans and aluminum helps airflow.) Lastly, try swapping that Radeon for a GeForce3 or 4. (eVGA and Hercules are excellent choices; however avoid VisionTek- I've seen many rants about freezing and restarting, not to mention little or no tech support.) Sorry for the late response, but I hope this helps someone.

I have had problems with rebooting before, 3 Gateway machines.
I tried the usual approach, with little sucess.
When I examined the motherboard I noticed the filter capacitors in the voltage regulator curcuits were crowned and had leaked some electrolytic onto the board. I removed these caps and replaced them.
The problem went away. These caps were 1500 ufd by 10v and cost about $2 total.
It seems as though the 5 volts had a lot of ripple on it causing the reset circuit to randomly restart the computer.
When you have ramdom reboots look at the caps.

I'm exactly having your problem. It's bizzare. My unit is an Gigabyte motherboard, P3 866, and a Rage Fury pro/Xpert 2000. Is it the Rage card? I don't know, because I'm sitting there, and all of sudden, my computer restarts for no reason -leaving me scratching my head. Is it easy to reinstall a power supply?

IF your 8500 is still under covered, I would return the card and try another. There is a chance that there is slight power fluctuations in the card that is making Mr. Motherboard unhappy.

It is also entirely possible it could be your power supply as well (even though you switched your cards and it works). The 8500 is a beau of a graphics card and does take a lot of resources. Are you running at least 300 watts? You should be! Can you swap Power Supply units and run the 8500 on your AMD 1800+ machine with the other power supply?

I have run built two computers with the K7T266 motherboard but did not have the same combination of parts. However, I have not had any issues like yours.

Sometimes, there are some combinations with specific hardware that just does not work. I once tried to install a two-port server NIC on a old Dual Tiger 133 motherboard. Computer would not boot. Not even get power. Once I removed the card, no problems. Took the card home and plugged it into my AZ11 Motherboard, no problems. Life goes on, I guess...

I would keep troubleshooting your hardware. You will find a solution! Otherwise, post back and I will think of something else to try!
