This is really strange...my computer restarts but only once everytime i turn it on, after then it runs fine and does not restart again until i shut down. Even if i reset it manualy before he resets himself i will work just fine, but he must be restarted after i turn it on... a7v266c barton 2500 2 x 256 ddr I have reinstaled windows couple of times, no change. Temperature looks fine (50-60 degres in load)... memory is tested and works fine.. Ayone have any idea ?
Do you have a printer connected that powers up from the same same source as your computer does or any other peripheral for that matter?
Nope, nothing is connected on that pc. I have tried this, if i enter bios after shutdown and just exit bios with no changes (computer restarts after you exit bios ofc), i will work normal until next shutdown....
Sorry. I didn't explain well. I didn't mean peripherals connected to the PC itself but peripheral devices connected to the same power supply, for example the PC and printer connected to the same surge protector or four-way adapter.
Nope... just my pc. Do you have at least any idea what should i try.. ? I don't get any bsod or any error log after pc restarts itself.. it could be overheat of processor but temp seems fine....
I doubt very much that you have any heat issues seeing as this occurs from cold. How far into the start process does it get before it restarts? Does it POST? Does it restart when it begins loading windows? How old is your PC /power supply?
Well, when starting, windows will work between 5-30 min. However many, almost all programs i start they display errors and close. Word, MSN, Firefox, Photoshop... If you mean does it leave any error log or bsod after reboot, then no... but i doubt that you meant that (sorry my english is not very good ). No. I have new power supply (maybe ~2 months old), i have changed my old one 350 W to new that have 400 W (but not from very good Manufacturer). Old one worked fine but molex was damaged so i had to change it. Btw, that barton i have (2500+), cannot be identified as AMD Athlon XP 2500+ in my computer but only as AMD Athlon (TM) processor, because my motherboard doesn't support fsb frequency that this processor requires... It currently works on 1.8 Ghz (12x150). My old one died and only one i found for socket A was that Barton .
Are these error messages always different? What do they say??? No. POST is a hardware check that occurs each time you start your PC. You'll recognize it as a couple of beeps just before your OS begins loading however you didn't mention that your PC would run for 5 - 30 minutes before it restarts which puts a different slant on its troubleshooting. [ot] You might want to check out the HWF rules, mainly number 9. Bear it in mind for further threads [/ot]
Yes, computer starts normal, with POST screen. Error messages... "This program encountered a problem and needs to be close..." And ofc i have an option to send error report or not. I will put error details of few programs if you think that will help .
Unfortunately a problem like this can be caused by lots (and lots) of different things so you need to start trying to isolate the problem. A good place to begin would be to start your computer and choose to boot using Safe Mode and just leave it to see if it reboots. This would identify whether its a hardware or a driver/software problem for example. You might also want to do a quick virus scan too as the Blaster worm used to cause reboots.
Same happens in safe mode. After 3 min computer restarts. No viruses, nod32 didn't report any... did a full scan just now. I just don't know what could it be... most likely it's mainboard, but i need to be sure in that. Could it be that some of the cables are damaged.. (from hdd or power...). I will test tonight with spinrite both of my hard disks.
Hmmm seems unlikely to me but its always good to do the simple checks so I would give them a glance. I think its quite possible that your HDDs may be a problem but I would approach it from a hardware angle and try to either test or swap out all the hardware you can. Lots of software testing tools have been recommended on these forums so I'd do a search through past threads, I'm afraid I cant remember all of the tools available Maybe Memtest will help and Fresh Diagnose. Hope these can help point you in the right direction
It's a bit old thread but i found a solution.... so i decided to post in case someone else have the same problem. Problem was in CPU frequency. I was some sort of a conflict when CPU was on 1800 Mhz.. now when i put down the fsb so it would be 1700Mhz or 1600Mhz problem was still there.. but when i adjusted fsb to match 1680 Mhz all problems gone . So if anyone encounteres a same problem just try to find the right frequency. In my case it was 1.68Ghz, but it all depends on motherboard you own. Thanks again all who helped me here. Best Regards.
