Hi everyone,

I am new here so sorry if this is in wrong place

My computer keeps rebooting itself, no warning just closes down and reboots. It only does this when it is first switched on for the day and usually within a couple of minutes of starting up, then upon reboot it will last a similar sort of time before shutting down again. Afterwards it will be fine for the rest of the time it is on. Sometimes it doesnt even do it at all.

I am just confused now, any help will be greatly appreciated.
Thanks

The error screen that appeared had:

stop: 0x00000050 (0x97EEB0A8, 0x00000001, 0xB514ABE1, 0x00000000)

kmixer.sys - address B514ABE1 base at B5129000 Date stamp 448fcd31


Hope this helps someone because it means nothing to me!!

Hi Kmixer is a key windows kernal audio mixer. This could prove to be a problem with the sound card. Try updating the driver also you could run sfc /scannow from cmd to repair any system files. Let me know how you get on.

These reboots can also be caused by a faulty power supply, a virus, or a bad video card, so you should test for these issues. Do you have any display problems or other weird things occuring with your computer? I had stop codes 7E and 50 with XP recently, and also had some display issues like odd wavy lines on the start menu area, which was a faulty PNY video card, ( replaced the video card and no more problems)
