A few things can be happening:
1. You have a DVD but only a CD Drive
2. The DVD is no good
3. Your drive is not working
You can also make a bootable flash drive to accomplish this:

1. Check in Screen settings to make sure the video output is going to the laptop screen, not the secondary out put.
2. make sure that you choose Extend displays.
3. There is probably a FN key at the top that will toggle between primary and secondary displays.
Suggest laptop is dirty inside.Air is used to cool the hardware components inside the laptop.If 'Gunk' coats these cooling components, (finned Heatsink, and small Fan Assembly), the cooling capacity of those cooling components drops Tremendously.['Gunk' = Dust, dirt, lint, hair, food crumbs,....you name it ]If the Processor overheats it turns off. (BIOS turns it off)This is a fail safe feature built-in.Keeps the processor from burning up. (Sometimes Literally!)Using Dell XPS laptop to show you the 'Gunk' that can accumulate,http://www.youtube.com/watch?v=AkAeE5I5E_AThis is an example of part of the cooling assembly; for an Acer Aspire 7720 series of Notebook PC,http://www.ebay.com/itm/Acer-5520-5315-7720-7520-ICW50-Cooling-Heatsink-AT01O000400-Free-Shipping-/251101918883?pt=LH_DefaultDomain_0&hash=item3a76d736a3Click on the photo to enlarge.The curved copper tube is the Cooling Tube.Slightly flattened copper tube, sealed on both ends, and filled with Nitrogen.At the top of the view, on the Cooling Tube; is the small metal aluminum plate that sits on the Processor.4 Philips head mounting screws.At the bottom in the view, is the rectangular finned Heatsink.The last cooling assembly part is the Fan Assembly,http://www.ebay.com/itm/New-Laptop-CPU-Cooling-Fan-for-Acer-Aspire-5520-5315-7720-7520-Notebook-/180933785266?pt=US_CPU_Fans_Heatsinks&hash=item2a207e76b2The small fan is a multi-bladed unit, that sits in a D-shaped shroud.In the view the Bottom is the opening.The opening sits RIGHT AGAINST the finned rectangular Heatsink.Heat is absorbed by the two small metal plates on the Cooling Tube, from the Processor, and GPU.The heat is then absorbed by the Cooling Tube, and transferred to the Heatsink.The Heatsink absorbs the heat, then radiates it away, with it's Tall, Thin fins.Air flow from the Fan Assembly, helps to carry heat away from the Heatsink's fins.If the Fan Assembly's fan blades are coated; and the fins of the Heatsink are clogged; the cooling capacity drops TREMENDOUSLY.Your Aspire 7720 may also has a separate Cooling Tube, and Heatsink; for the graphics chipset. G.P.U.,http://en.wikipedia.org/wiki/Graphics_Processing_Unithttp://www.ebay.com/itm/Acer-Aspire-7720z-Graphics-Card-Heatsink-AT000000DV0-/310526872287?pt=LH_DefaultDomain_0&hash=item484cd80adfKNOW THIS;The top of a Processor, and the top of the graphics chipset; is Not perfectly smooth.Neither is the bottom of the metal plates of the Cooling Tube/s, that sit on them.A magnified view would detail, 'Hills, Valleys, and Pitholes', in the surface.When the two parts are mated together, (Processor/Cooling Tube plate; Graphics chipset/Cooling Tube plate); there are air pockets that are created.Created from the imperfections listed above.Air is an Insulator; not a Conductor.Thermal Paste fills these imperfections, and is an Excellent conductor of Heat.There may be also Thermal Pads that are used. Pad material impregnated with Thermal Paste.After time, and repeated heating from the Processor, and GPU, (Graphics chipset), the Thermal Paste dries up.It also looses it's thermal conductivity properties.SINCE, all you have to do is remove the large panel, from the bottom of the laptop, (Battery Compartment facing Away from you; the large panel to the Right), you have full access to all cooling components.It would be in your best interest to remove the Cooling Tube/s/Fan Assembly, and clean the top of the Processor, and GPU. Also the metal plates of the Cooling Tube/s.I use an old credit card to scrape as much of the old Thermal Paste off, as I can. (Needs to be plastic, or wood; because it needs to be Anti-Static. NO -> Metal scraper)Use Q-tips dipped in Isopropyl Alcohol. (Rubbing alcohol)91 percent is best IMHO, but 70 percent will do.To me 50 percent = No. 50 percent Water, and 50 percent Alcohol.Takes a LOT of alcohol soaked Q-tips, as it's usually a gooey mess.CAUTION!!Isopropyl Alcohol is EXTREMELY FLAMMABLE!Use in a WELL ventilated area with NO sparks or flames present!How clean? Literally clean enough to eat off of. (Don't worry about excess alcohol dripping down. It will evaporate)Now PROPERLY apply fresh, new Thermal Paste for the Processor, and CUT a new Thermal Pad for the GPU.{Old thermal pad is carefully peeled off }http://www.hardwaresecrets.com/article/274http://www.tigerdirect.com/applications/SearchTools/item-details.asp?EdpNo=3071621&CatId=503http://www.ebay.com/itm/Blue-100mmx100mmx0-5mm-GPU-CPU-Heatsink-Cooling-Thermal-Conductive-Silicone-Pad-/190704122314?pt=US_Thermal_Compounds_Supplies&hash=item2c66d9f9caScrews for the Cooling Tube processor plate, and GPU Cooling Tube plate; are lightly tightened down until they touch, then tightened in a crisscross fashion.You want the plates to sit F-L-A-T on the Processor, and GPU.DO NOT OVER TIGHTEN!!Free Service Manual so you can disassemble,http://www.tim.id.au/blog/tims-laptop-service-manuals/#toc-acerGo to the 'paragraph' that starts with Aspire 1200. (1200 in Blue)Drop down to the 12th line. (7530G in Blue)Scroll across, and click on 7720 in blue.This is a PDF file. The computer you are using now has Adobe Reader on it, which uses PDF files.After you click on the file name (7720) it may take up to 30 seconds, before the first page comes up.(The PDF file is downloading in the background)Buy and use an ESD wrist strap. Connect it's alligator clip to a good ground source.Electro Static Discharge.Your body carries Static electricity. Static WILL fry out (Short Circuit), the delicate hardware components inside a computer.You CANNOT just touch the metal framework, as you would for a desktop computer; to relieve your body of Static.Average price is around $3 to $6. Here is but one example,http://www.radioshack.com/product/index.jsp?productId=2103245I connect to an unpainted surface, of the metal frame of an open, empty desktop computer case.I feel an Anti-Static Mat is unwarranted. (And I have a repair shop)You can set a large metal serving tray (Unpainted), on the table you're working on; and connect to it.Or a large metal knickknack. (Unpainted)You get the idea.Use a mutli-compartment container for the various screws you will remove. Label each compartment for the area the screw/s come out of.SOME screws look VERY similar to other screws.Advise DO NOT mix them up!Use a small soft bristle brush, (Makeup brush?), Q-tips, and a can of compressed air for computers, to clean the inside of the laptop out.Especially the fins of the Heatsinks, and Fan Assembly.For additional questions please post in a Comment.Regards,joecoolvette
It sounds as though you have a problem with the power button itself, this is on a small cicuit board beneath the top panel where the button is situated, these boards are not too expensive and eay to change providing you are competant with a screwdriver. If not I would recommend that you get a technician to take a look.
If the hard drive have crashed meaning that the hard drive itself is damaged, then your solution is to replace a new harddrive. If you do have a recovery disc already made, or one is provided then you will have to use that disc once the hard drive is replaced with the new one, and follow the procedure to reinstalled the operating system. If the original hard drive had crash and does no work anymore (where the bios/computer cannot detect it) and you have important data that you would like to retrive, there are places such as office depot, bestbuy, where they can help you send it to a recovery file center to recover files from your damaged hard drive. Do not attemp to fix or open a damaged harddrive, you can forever damage the files on the cyclinder disc. 2) Now if your harddrive crash in term as windows just crashing and you cannot get into your operating system and the bios is still able to detect the hard drive, and it's giving you a error message, then you will only need to reinstall, or do a windows recovery through your recovery disc, If you do not have a recovery or made the disc, then you will need to buy a new operating system software. If you computer does not start meaning no display on the screen at all, then please replay back. That is a different story.
If the Computer is detecting only CD's or DVD's then the issue seems to be Hardware related, please perform recovery even after that the issue persist get the unit serviced.
Sounds like a problem with the battery. Try removing the battery from your notebook and then plugging in the power adapter. If it's still giving you the same problem then you will need to take your computer in for service as a hardware problem indicates something may need to be replaced.
Hope this helps.
Hi friend,
In this case i would recommend you to please try and install the latest video drivers for the laptop and also try to move the screen of the laptop up and down to check if it makes any difference because it might be possible that the LCD cable is loose.
Welcome to Fixya.
If you have forgotten what the password is, I am sorry to say that the HD is as good as dead. Unlocking it is possible via PC3000 but unfortunately, the cost of this kit is like brand new car's price tag. You can use the program that comes with it and a probe to short specific points in the PCB.
You give it a shot with AFF's Unlock Wizard.
All the best! If you need further help, reach me via phone at https://www.6ya.com/expert/elixirjose_00375ea24bd8141b
Hi,
Start the laptop then as soon as you have pressed the start button hold the F8 button down you should get a repair restore safe mode screen where you can enter safe mode to see what is causing the start up files not to load then repair it if not then you can do the process again and restore to factory.and refer http://tips4pc.com/articles/computer%20troubleshooting/computer_has_a_black_screen_and.htm
Manufacturers homepage will supply most of the drivers you need, if you run Windows Vista or Windows 7 you will get drivers for all common components on the market through the Windows Update tool.
