Laptop restarted by itself, then error message : PCI vendor and device

Hello Q2 mate what are the temps on that CPU?? for starters. Use this and post back Speccy - Free Download - Piriform

Now I would also be running these if you can get into safe mode

SFC /SCANNOW Command - System File Checker
Disk Check < if necessary include the /f and /r in the command line as per Option2
Run these in safe mode and the sfc often best run for two to three runs (with a reboot between each one) – you can leave out the /r switch in ckdsk if you feel it not necessary

Hmm temps a bit high for my liking that is at what you say is a low level operation. Have you checked to see if the air intake and fan are clean if not follow this
CLEANING A LAPTOP FAN & COOLER RAD
The thing you do is to turn over the laptop and shine a very bright light into the air intake aperture (you will see the fan there) and then while doing that look at the outlet vent on the end of the laptop you should see the light quite clearly shining through the cooling " radiator" if not it is clogged and will need cleaning as will probably the fan opening.
You can do this by blowing it out using a compressed air can in short bursts.
BUT ONE WORD OF WARNING*DO NOT blow the air into the fan opening without inserting say a plastic rod or large cable tie to stop the fan from spinning as the air blast will spin the fan at a very high speed that it is not designed to take and may wreck the bearing!!* There is also the fact that doing this can produce a voltage that can be up to almost 12v which while the fan is connected to the board will introduce that voltage into the machine and again can cause severe damage if not wreck the board and/or components.
To clean the "rad" I use those pipe cleaners to GENTLY loosen the crud and then blow it out*of course*disassembly makes life so much easier.


No mate I haven't come across that message to be honest at the moment I would be more concerned about that CPU temp.


Edit: Now do the temp bit first but then try this PXE E01 PCI Vendor and Device ID Do Not Match Error
