today I had problem with my client lapto, first everything worked ok as usual and then I had to install new POS printer and I also had to install driver for COM port (3 and 8). After installing these drivers laptop started to auto shutdown every 5-10 minutes.
I assumed problem was in new drivers and because I made some minor changes in Device manager so I decided to run restore point two days backwards because I didn't have these problems then and after I finished that nothing changed because laptoped continiued to autoshutdown first each 10 minutes, then each 4-5 minutes and then again every 10 minutes so there isn't any fixed autoshutdown interval.. Also at the momment when laptop is shutdown, when I try to turn it on I can't so I have to wait for 1.5-2 minutes to turn it on again.
I am not sure what's the problem because I don't see any error message and I never had any similar situation before.
Any help is appreciated and many thanks in advance for prompt replys.
