Black screen after logo with blinking underscore, nothing is working
Before any bashing lectures, yes ive searched google for days on this issue and no fix or shortcut key is working. Its a dell studio from 2008, hard drive is only a year or 2 old. Ive tried changing around bios in f2, resetting defaults, every boot option in f12 gives me the same screen. Diagnostics do not start at alk, same black screen with the underscore. Ctrl alt delete restarts the whole thing, fn and power button doesnt do anything. No i didnt do anything to my comp, turned it on one day and it goes to black screen underscore after dell logo. F8 doesnt work, trust me that shortcut has NEVER EVER worked. Ive hit every single f and number key there is, nothing works. Just f2 and 12 but theres nothing there. Ive tried a recovery disc and it never starts, yes ive used cd boot option in f12 plus changing bios ordet, same black underscore screen. Ive takenout everything but the power cord, even battery, same thing, it doesnt even give me any error sunce the battery was out. Ive tried it all belueve me. Also since my warrenty is up, dell refuses to do anything, i cant get the email info or use the live chat. If its a straighr motherboard issue can someine just confirm it, ill replace thibgs myself.

A blinking cursor in the upper left corner usually means the boot is being directed to a device which is not a bootable OS.
If it is from 2008, it certainly did not come with Win 10, so what OS did it come with and what OS is it running now?
The drive replacement 2 years ago was for drive failure and if so, how did you recover the system?
If you have a bootable install media or recovery media, it should boot, or at least show it as an option to boot.
The hard drive being one or two years old may not be a good way to judge if the drive is involved. I have taken a brand new one out of its packing and see it fail.
If you really cannot get any media to boot, not even an Ubuntu version, there may be something major wrong. I don't think I am still using any systems which were working in 2008.

Unplug the system, remove the battery and hold the power button for 30 sec. Remove and reinstall both memory modules and the hard drive. Try powering up on AC only - no battery. If it'll power up that way, the battery is bad.
If it won't power up on AC only, remove the hard drive. If that gets you into setup, the drive is bad - replace it.
If it doesn't, the mainboard is bad - in which case, consider a new system. After nine years, this one isn't worth replacing - and you can likely find much newer systems for sale used, which will be on par with the cost of a board replacement on this one - and much faster and up to date as well.

As i said, ive tried every boot option in f12 and still get black screen, and using bios to boot hard drive first as well as my recovery disc. Everything goes to black screen. It was a win 7 before i upgraded to 10 a year ago and it has worked fine. The hd replacement was a virus but i did the replacement myself and never had a problem til now. And yes my laptop runs off ac adaptor because my battery has been dead for a long time and still ran fine til now. Ive never had to replace any part except hard drives
