Wanna play games with no barrier in performance?? Check here my review on the best-ever game performer Dell Laptop. Dell Alienware 15 r4: https://www.cutpriceretail.com/blog/laptops/amazoncom/18328-dell-alienware-15-r4

Try a System Restore and select a restore date before your problems started.To get to the System Restore - Click on Start - All Programs - Accessories - System Tools - System Restore

There are a number of reasons that the unit could be freezing up.

1. Corrupted file(s)
2. Low available disk space
3. Viruses and/or malware
4. Too many add-ons/toolbars/etc.
5. Heat build-up

Number one is the hardest to find. So start with #2. The computer needs free hard drive space to operate. If the disk is nearly full or is very fragmented, this can slow the machine to a crawl. Check for available space and if there is plenty (20GB or more), then check for fragmentation under administrative tools. If the defragmentation tool recommends optimization, allow it to perform it and see if that helps. For viruses and possible malware, run your virus scanner. It is always a good idea to get a second opinion on such things. Malwarebytes is a free malware scanner that works very well to find adware and some things that many antivirus programs fail to detect. Many user feel that they have to have every bell and whistle. I've seen some browsers with 7-10 different toolbar add-ons. These almost always come with some adware and always slow down the browser. Uninstall all but the most essential toolbars for the best performance. Heat is a slayer of machines. Laptops are very susceptible to heat issue since they are often placed on beds, sofas, carpets, and yes, even laptop. Many of these units draw cooling air from the bottom and exhaust it to the side. Even those that draw air from the rear and exhaust to the side will often intake large amounts of dust, grit, and lint. These can partially or completely clog the heat sink unit and cause heat buildup of the processor. This will cause the processor to work slower and can actually cause it to thermally lockup, resulting in the need to reboot. Many units can be accessed to clean with a removable cover on the bottom; others may need to be serviced by a technician to clean.

Its because the display drivers are not installed, try installing display drivers

You have to look at the cable connections on both your TV and Laptop. They should both have the same HDMI connector. Check your Dell Manual to see which connector is the HDMI If you don't have a manual for your Dell: www.dell.com/support Will have the manuals free. Hope this helps.

well , it has no such thing , look at he mobo , the GPU is soldered down and there is no PCI-express slot there, so there is no such thing why not just post my video is dead to LCD and external monitor jack both. The LCD here uses a CCFL back lamps that die even 5 years old the flash light test proves that as does the external monitor jack Fn+F4 enabled (hot key) there is no card, post evidences and stop listening to desktop gamers./ jive kings. ok? do the flash light test first posted here 1000 times now. nothing new here. its pre 2010 PC junk https://www.pcdied.com/monitors_and_screens/flash-light-trick.html#flashlighttest in dim room power on PC while pointing FLASH light to CLD face (screen) see data, ops, CCFL dead. if yes. and data at ALL.

connected how, 3.5mm jack (mic port) or USB mic like mine i can connect both and then in the mixer sound windows click on mic input I want control panel sound recording tab , pick one./ if usb fails try all USB ports. my usb mic real fancy with built in sound effects even echo and more. there are like a gazillion types of mics now, boom mics and gee and endless list. even gun mics. to avoid noise , near by. no mic told, at all no OS told ,windows guessed a usb mic also must show up in device manager or will fail

no PC told , at all, model not told ok generic mode. 1: huge battery inside is bad, shorted remove it , even for ever. 2: run on AC power only now. 3: push power button 10 full seconds release, ,runs now? 4: no, remove all USB devices now. run now? 5: no, coin cell battery dead, , replace it , run nolw 6: no. strip the PC down to find the shorted model. lap-strip-101 https://www.pcdied.com/Dead_screens/dead-LT.html

NO if you do, a noob will blow it to kingdom come. as in letting the smoke out. the power-pack does 3 things it has the correct DC voltage and wattages and #2 prevents fire when the PC fails and things short inside. and prevents huge damaging surges landing inside the PC buy used power pack off fleabay and win. i bet I'd mow one lawn and and buy one

ask them your 3g? service provider and the HP hardware 3g does not work there. HP does not have that. let me be clear, ask the ISP. this. yours. ask them for the hardware to do that. most ISP only have few modems that do this and only theirs why not ask them , we in USA ,same answer. They have phone to call for support, so call them 3/4/5G call them. the Sim slot is only for the HP WWLAN card and only works with that card and that card is useless in Uganda, as is the HP sim slot, call them. here I am in USA and have T-mobile (example) i CALL THEM AND THEY TELL ME SORRY 5G LTE IS ONLY FOR YOUR CELL PHONE.! (later things can change) AND MEANS NO MODEMS SOLD OR RENTED TO ME.(for PC's) THERE ARE LIKE WHAT 10,000 ISP ON EARTH, NO 2 THE SAME NOR SAME MAP AREA COVERAGE. TOWN BY TOWN CALL THEM. sorry my crystal ball is fuzzy this week.
