Hello, let me start by saying thank you for any help you can provide. My level of tech knowledge is pretty high, and yet I am stumped by this issue. I know this community is a source of high quality reliable knowledge, which is why I turned here both in the past and now.
So, here is what is happening. My computer suddenly restarted on me this morning and when it tried to boot, I receive the dreaded blue screen of death with the most reoccuring error being c000021a. However, this is not the end of the problem.
Sometimes it won't let me enter into safe mode, or even run the repair diagnostics. Other times it will. Sometimes it will almost load safe mode et al. but then end up on a perpetual black screen with nothing happening. Other times the monitor will simply wig out and flash a ton of bright colors at me.
It goes without saying, but I have attempted a system restore to no avail several times. I have uninstalled recently installed programs whilst in safe mode, and I have run ever repair diagnostic I can think of. Nothing seems to be fixing this issue.
Obviously, the next step I can think of is to do a system wipe and reinstall everything, OS and all, but that does not strike me as a great option, and I'd like to avoid that if possible.
Please, don't assume I've done anything right or wrong, and just give me the best advice you can. I'm willing to try anything possible. Any help is appreciated. Thanks!
