I have a Dell Inspiron 15R 3521, bought it a couple of years ago. I was working on the laptop and I got up for a while, when I came back the laptop was in standby mode so I pressed the power button and the laptop showed me a message "Error has occured and windows need to reboot" I pressed the reboot button and the laptop booted up and while it was still booting the display was all funny with little white and color boxes. I immediately pressed the power button to turn it off sensing there might me some boot error. Again I tried booting the system but it would not go past the dell logo. I tried a few times but with same result.
I tried again after some time but this time the screen was blank not even the Dell logo. After which I tried resolving the issue by visiting the dell forums.
I have
1. removed the battery and pressed the power button for 30 seconds which made the dell logo appear again but that was it.
2. did the static discharge again this time the screen showed me the dell logo with Boot options and the blue progress bar. I pressed the F2 key and nothing
3. Tried it again and this time it showed "Media Fail" twice.
4. Tried it again and this time it showed me some options to disable and enable some things. I pressed the key to boot in Safe Mode the laptop rebooted and the blank screen was back.
5. I have done the memory module switch with no luck. If I remove the memory it gives 2 beeps. I replaced the memory in its original slot.
6. I then removed the CMOS battery to reset the Mobo to it original configuration. I got 5 beeps. I replaced the battery with a new one.
The laptop still didn't boot just the blank screen. I am not getting any response on the 1800 helpline I have tried for the past 3 days. I have done all the trouble shooting I could I even tried the Fn + Power button but nothing.
Now when I turn on the laptop the power light comes on the fan starts the optical drive comes on the hard disk light comes and on and then the laptop power down. I dont know what to do any more. I read somewhere on the Dell forum that it could be mobo related and replacing it would do the trick but I have an i7 so it would cost a lot more and still no guarantee that it would stay good. The laptop was all good but ever since Microsoft shoved windows10 down our throat I have been experiencing one issue or the other like every time I reboot the laptop me standby and sleep setting revert back to default. The laptop sometimes would not know whether its in standby or hibernate mode. I didn't want win 10 in the first place and rejected the upgrade many times but it would still download automatically and ask for installation and I had no choice but to upgrade. I think the generic drivers i.e. the replacement drivers for certain components which are provided by Microsoft slowly corrupt the said component until the laptop stops booting altogether. Please help as I need my Laptop for presentations for my client. Its just a mess all around.
Thanx.
