Surface Pro 5 News - release date, UK price, features, specs
Hi i bought my laptop a couple of weeks ago. And now for somea reason i cant see my CD/DVD drive when i click on My Computer and when i insert a cd or dvd it wont boot up. I went into device manager and under the cd/dvd drive it says
"Windows cannot verify the digital signature for the drivers required for this device. A recent hardware or software change might have installed a file that is signed incorrectly or damaged, or that might be malicious software from an unknown source. (Code 52)"
I am running windows 7.
I am going to take this back to pc world tomorrow if i cant fix it, but thoughy i would try mself first before i drive up.
No CD/DVD or CD-ROM access is missing error Code 19, Code 31, Code 32, Code 39, or Code 41
Try this if the optical drives are not appearing in My Computer or Device Manager.
