Windows 7: Interesting problem booting I've never experienced before

Interesting problem booting I've never experienced before

Scratching my head on this one because there never been a problem with computers in the last 14 years I couldn't resolve... I've narrowed it down to two possible problems.. PSU or MB.. I'm leaning more towards PSU have problems under load, when booting video card draws a lot of power... I don't want to go buying new parts just yet to test it out but open to suggestions?

This is what is happening: Boot process goes through POST no problem, makes me think MB is fine. Then comes to a black screen with white blinking hyphen instead of going to Windows loading screen as it does normally.. I thought it was Windows problem first or hard drive issue but did all the proper maleware/antivirus checks all clean and other operating system and hard drive diagnostics Everything comes back error free.

It was an intermittent problem but now pretty consistently occurring but alleviated if I disconnect any one component, use the onboard video, or disconnect one of my two extra hard drives. The only thing that makes me hesitate to declare it a PSU problem is I checked all the voltages on the PSU and they all check out nominal, even under load not dipping below accepted levels... runs perfectly when it does boot up correctly or if I disconnect a component from the power.. are you like me and think it's the PSU?

Can I make a suggestion? Uninstall Trend Micro, and see it the problem replicates.

You already have Avast, so Trend is not required and may hamper the post-boot environment. Admittedly your problem sounds as if its pre-boot, but Im taking a bit of a guess after seeing your antivirus setup. Leave Malwarebytes as it is.

Exactly how many fans are connected?

Spybot is also about ten years outdated with tech enthusiasts, ever since it bloated up with buggy add-ons. I'd replace it with SuperAntiSpyware.

Use MSE with Windows Firewall only, Malwarebytes for on-demand scanning.

Other tips for what works best with Win7 in Clean Reinstall.

Lol I should have mentioned I don't use anti-malware or antivirus unless I need to fix something.. So much for preventative maintenance lol I don't goto suspicious websites or download shit I don't trust, i rarely get infected.. It's easy to check if a website is safe first before following links

I'm pretty sure I answered my own question for most part.. I already deep scanned all hard drives in safe mode and console came up with nothing.. Thanks for the suggestions, I definitely feel like its a power related issue even though voltages check out since if I unplug a hard drive or video card then comp boots and runs like a champ.. I know you tried your best I appreciate it :-)
