PC Rebooting randomly

[Razorsidewalk]

Over the last couple of weeks, my PC has started to reboot itself randomly and for no apparent reason that i can see. I first noticed it when i used to leave it on over night when i was burning DVDs, i would come down in the morning and the PC had rebooted itself and it was during the burning process and thus my DVDs never finished burning. So i thought it might have something to do with the Nero software i was using, so i reinstalled it all and it looked like it had stopped rebooting. But now it has recently just rebooted itself when i havent been burning, so it cant be Nero. I would just be on the internet and doing somethign and then it would reboot itself. The only thing that has changed recently since this started is that i have installed a new Graphics Card. I used to have a Radeon 9800 Pro (128mb), but now have a Radeon Sapphire X1550 (512mb). The drivers for this are all up-to-date.

I have de-fragged my PC since this started, i have run a few spyware programs and other cleaning programs, but still it does it. I have Windows XP Home. I have never had this problem before. I have even looked in the event viewer to see if something shows up there ad the only erros at the time of rebooting are the following:

Error - Source - AVG7 - 2007-11-16 12:59:03, 593 VOYAGER [002100:002727] ERROR 000 AVG7.CC plugins. CAvgCcPlugin plugin refresh failed: Error 0x80004005

And there seem to be a ot of these erros in the event viewer, so could have something to do with my AVG Free Adition virus, but if so it has never happened before and i have had this virus scanner on my PC for nearly a year now if not more.

Can anyone help me as i have no idea why this is happening.

If u need any other information then please ask and i will try to provide it.

Thnx

Being that you get that AVG error, my best advice would be to download the latest verison of AVG. Then disconnect from the internet to prevent any net traffic during the process.

Uninstall AVG completely. Reboot. Reinstall AVg. Reboot. Connect back to the internet and update.

See if that helps.

I did the above. I also unticked the "Automatically Restart" under the "Startup & recovery" in advanced tab in my Computer, so i would get an error message instead of the PC just rebooting. So i started off a DVD to burn and left the PC running, came back a few hrs later and i had a blue screen error.

The technical code i got was:

0x0000000A (0xA6D89000, 0x00000002,0x00000001, 0x8066AAA2)

If that means anything, but apart from that the error message wasnt very helpful.

Any other ideas?

Thnx

Typically, this error occurs when a driver uses an incorrect memory address. Other possible causes of this error are an incompatible device driver, a general hardware problem, and incompatible software.
Have you updated all your hardware drivers lately? Since this always seems to happen during a DVD burn you may need new drivers.

You might also do the following;

Check your hard drive for file/system errors by running chkdsk. Open My Computer and right click on Local Disk C: selecting Properties, click the Tools tab and in the Error Checking area click the "Check now" button and select both options. It will tell you that it can't test the drive right now and it will ask if you want to schedule it for the next system startup... select Yes. Restart your computer so that it can check the drive. This test will take some time to run and at times may appear stalled but just let it run.

Follow up all of that with a full Defrag using Auslogic Free Defrag program, much better and faster than the built in Defrag progam. to ensure the best performance you can of the system.

This random reboot doesnt always happen during burning DVDs, it has happen 2-3 times when i have actually been on the pc in the middle of other stuff.

I had updated all my drivers for the graphics card and the mothreboard chipset aswell.

I tried running chkdsk, but when i rebooted the PC, it froze in the boot up sequence when the Windows logo is on the screen and the bar below is running from left to right. I have down a defrag also and also gave the pc a clean inside removing dust etc from fans.

I did leave the PC on last night and had a BSOD error this morning which said BAD_POOL_CALLER. And the only hardware i have installed recently is the new graphics card, then this rebooting seem to start shortly after.

Then I would look at that graphics card. Be sure you have the correct drivers installed for sure.
