Hello guys, I hope this thread is in the right section. If not I request the mods to put it in the right one. I've been having problems with my laptop and cannot find a definitive solution so hoping you guys can help

I have
Dell Inspiron N5010
Windows 7, i5

My laptop recently shut down while I was on it and when windows update was installing. It suddenly went really really slow, the cursor started blinking so I tried to shut it down. There was a windows update going on so before it shut down it said installing update the computer will shut down after update installed and then it shut down. I tried to boot it up again but it wont. Here is the specific problem

When I boot it up it shows the dell screen, beeps once and then goes blank with a blinking cursor top right and nothinf happens. I can press f12 or f2 to go into setup and it allows me to do that. It also allows me to go into BIOS screen when I press f12. When I try to run diagnostics from the f2 set up options the diagnostics starts but gets stuck on the "Running MATS Test" thing.

Once in a while it doesnt beep and progresses to the "starting windows" logo screen but stops there. Once I was able to actually get it started and it ran fine but when I shut it down it wont start again.

The fan runs when I boot up. i tried removing the battery and purging static by holding the power button for some time but to no avail. I also reseated the RAM but no go with that too. Online I found that 1 beep for Dell means a "BIOS/ROM error or failure" but I dont know what that indicates or how to solve that.

I must also mention that my laptop has randomly shut down before due to overheating but its very rare and never before did this happen. I also bought a new adapter and this problem happened the very next day.

So could this be a problem due to the adapter or did the windows update not happen properly or is it an overheating issue? Would I need to change my CMOS battery or flash the BIOS? Or is it worse like changing the motherboard?

Any help would be great appreciated
