My computer is spontaneously rebooting!

Hai Friend
I think you have done almost all tests. Still I will give some suggestions. Once check with Prevx1 anti malware software. It is a powerful anti-malware software.You can download it from the following site. http://www.prevx.com/security.asp If the above not works,then first scan the system with Bit Defender Antivirus Plus then with Avira AntiVir PersonalEdition Classic. Before using these softwares you have to uninstall your AVG antivirus.If these softwares find any virus affected files remove them. But becareful some programs may not work if you remove some virus affected files. So I will suggest you to read completely the article below on Viruses then do experiment on your computer. The article is: http://technodata.blogspot.com/2007/...s-glowing.html So after the above tests you will come to a conclusion whether your computer is affected by any virus. If you come to a conclusion that your computer is not affected by virus then do like this. Freshly format your harddisk and reinstall Win XP Pro with service pack2. Even then your computer giving problem then you can come to a conclusion that it is completely hardware problem. Then by trial and error you can find which hardware component is giving problem? O.K. Don't think that I am testing your patience. |

My computer is spontaneously rebooting!
Over the last few days, my Compaq has become increasingly unstable, and
now reboots occasionally in the middle of things. It can be anything - in the middle of AVG Antivirus 7.5 doing a virus scan, or my kids watching a DVD. The very first time I noticed something strange was when I inserted my Sandisk Cruzer into the front USB port. Instead of taking a minute or so to transfer files, it told me that it would be something like 1200 hours. I rebooted the system, and next time I inserted the cruzer, the machine rebooted. The only thing I've changed was about a week ago when I replaced an old DVD-ROM drive with a newer one. In the past, I've also had an additional hard drive in there, so I'm pretty sure it isn't the power supply - there is actually less power usage on it now than it had a month ago. So, here are the testing steps I've taken: 1) reseat the memory, power and data cables 2) double checked master & slave settings on my IDE DVD burner & IDE DVD-ROM 3) checked all the capacitors on the motherboard for swelling 4) checked CPU temp - running at a very cool 89 degrees F - not surprising for a Sempron with HUGE heatsink 5) ran loads and loads of test utilities from Ultimate Boot CD on the RAM, CPU, motherboard, hard drive. One of the several tests I ran on the USB ports showed a possible problem, the rest did not. 6) I went in to safe mode, removed all USB related items, & rebooted 7) Loaded AVG Antivirus 7.5 & latest virus pattern to make sure this isn't virus related 8) since I've seen it lock up a couple of times using Realplayer 10.5 Gold, I completely uninstalled, then reinstalled. After uninstalling, there was one file left in the folder I couldn't delete until going back into safe mode. Jury is still out on whether any of this made any difference. I am wondering if any of you recognize either of these error messages that popped up on my screen. The first one: http://aycu30.webshots.com/image/115...7060620_rs.jpg Shows what came up after a spontaneous reboot. I would get something about Windows recovering from a serious error, then click on details and get this. The strange thing is, I couldn't even find the described folders on my hard drive to look at the files for more information. The second message: http://aycu38.webshots.com/image/140...0802289_rs.jpg I first got while we were watching a RealVideo file. However, later I got it while AVG Antivirus was running, and another time we got it when I was doing something else completely unrelated to playing videos. It seemed to just pop up randomly, and I've never seen this sort of message before. Anyone have any hints or ideas? Thanks! P.S. - What really makes this a bitter pill is the fact that I've lost 3 motherboards over the past month and a half. All were ECS motherboards of the same vintage, and all died because of swollen or even burst capacitors. I lost my primary PC in our living room, the one in the basement that we used to watch videos when exercising, and the one I had to use as a backup for the one in our living room, about two weeks after replacing it. Now I'm having issues with the Compaq in our bedroom, even before I've gotten the one in our living room back up and working with new innards. Blegh! It just makes me want to go back to the analog age for a while. |

As another noted, did you view historical data in system (event)
logs? That is the right intent - to find the problem before replacing anything. But the foundation of any computer is its power supply 'system'. Not just a power supply; a 'system'. Two minutes with a 3.5 digit multimeter will accuse or exonerate system components. Procedure is in "When your computer dies without warning....." starting 6 Feb 2007 in the newsgroup alt.windows-xp at: http://tinyurl.com/yvf9vh Those numbers either identify a problem or are posted here so that the better informed will reply with useful information. Once the power supply system is confirmed, then comprehensive hardware diagnostics are better executed in heated environments. Hardware that fails intermittently at 70 degrees F tends to fail diagnostics repeatedly when operated at the completely normal temperature of 100 degree F. A hairdryer only on highest heat setting is also a useful tool to create heat. Very little hardware will crash a multitasking OS system. That is limited to memory, CPU, video controller, soundcard, and power supply system. Those items are best 'selective heated' to find intermittent hardware. Heat being a diagnostic tool - just like a 3.5 digit multimeter. Little in any system is identified defective by visual inspection.

It is itself basically a root kit which thoroughly hooks itself into the kernel. It connects to the internet each time a process is executed to enable the prevx database to be updated and checked. This would be all well and good, except that PrevX makes your machine unstable and VERY SLOW. It is very hard to uninstall it properly and it is common for it to encounter problems during uninstall, which leaves parts of it still installed. Steaming dog turd material of the first order. |
