It allowed me to log in, then it fiddled around, gave me the gray/black screen of death.
After a few minutes of that, I turned it off.
A bit later I turned it back on, logged in, seemed like it was getting ready. I left it alone. Now I have the green blue screen of not dead yet.
Any doctors in the house?
I'm on my phone.
There was one trying to sell a free farm last week. Maybe he's still around...
I'm certainly a tech-y guy, but I foresee this being like calling a mechanic and trying to reproduce, over the phone, the sound that your car is making.
Fundamentally, all your error screens (the so-called BSOD - Blue Screen of Death, the black/gray memory dump screens, etc.) are a result of your operating system (OS) having an electronic stroke. Unfortunately, it can be problematic to determine the cause as many "apparent causes" are really just symptoms of the root cause.
For instance, it might appear that an OS is corrupted, and so a clean install might fix it. But was that corruption caused by a virus? Was it a collection of independent actions that made a unique case? Maybe your hard drive itself is dying. Maybe you lost power last night while your system was updating. Maybe a lightning strike hurt your power supply. So many possibilities! There us a reason that Best Buy's geek squad has something like a 10 minute timer before they give up and do a clean install!
We can probably solve this, but its primarily going to be a function of your determination to save THIS computer with THIS OS installation...and it will take time to do back and forth on a forum.
To start with, some questions for you.
1. Is this a desktop or a laptop?
2. If a desktop, does the motherboard have a status code display? (You would have to open the case to see it)
3. If it's a desktop but do not have a status code display, you can buy one and see what the hardware is doing. This is the surest way to troubleshoot if theres a hardware issue.
4. When you try to turn it on, do you get a splash screen (like a Dell/HP logo)?
5. Can you get into the BIOS settings?
6. Does Windows (I'm assuming its windows...) start to boot at all?
Let's start with those and see where we get to.
