Thank you for the reply, and sorry for the misplaced topic.

Honestly it never occurred to me that the age of the PSU could be a problem. I was in a "plug and play" mindset and was concerned more with the wattage than its age. The new graphics card I wanted to put in is an AMD Radeon RX 560 4 GB GDDR5; the card that was delivered with the system which was going to be replaced was the same, but just 2 GB, and the PSU didn't even hook up directly to it.

Might explain why my Corsair 650W didn't quite fit. I also saw some talk about how systems upgraded to Ryzen motherboards were supposed to come with an 850W PSU instead of the standard 460W since they had twin PCI-E slots, but people ended up with 460's and not 850's. I'm going to keep looking into it.

Thank you.

I had some good luck asking a question about my PC here a couple months ago, but unfortunately I'm back for round two.

I purchased a new PC from Dell ( http://www.dell.com/en-us/shop/dell-desktop-computers/inspiron-gaming-desktop/spd/inspiron-5675-gaming-desktop/ddcwrdsk920s/ but mine has a Ryzen 3 instead of the A10) to replace my HP that had it's PCI-E motherboard slot go bad on it. The HP was 5 going on 6 years old so I felt a new purchased was a good idea. I got a good deal on it, and it seems capable of suiting my needs.

After a brief setup period I moved my 4 TB drive from the HP to the new Dell. No problems. Then I tried to move my HP's power supply--a non-standard Corsair HX 650W Professional I installed myself--from it to the new Dell. After removing the Dell's PSU and making all the connections, I tried to start the computer. Nothing happened. No sounds, no lights, no smells, no nothing.

I tried different connections, including removing some extension cables inside, but it didn't work. I removed the Corsair and put the original Dell PSU back in. It worked perfectly. I put the Corsair back in the older HP. It worked perfectly. I put the Corsair back in the Dell. It doesn't work.

After racking my brain, I am at a loss. I don't get why it doesn't work. I've tried different power cables, and yes the switch on the PSU is on and it's always plugged into the wall outlet and PSU. The Corsair PSU just doesn't jive with the new system and I cannot determine why.

I'd like to note that the Corsair does not quite fit in the case. It did in the HP case, perfectly, but in the Dell case it's just a tad too big. I don't know if it not "locking" into place has any bearing on its functionality or not. The Corsair is also about 5-6 years old, but runs fine. I need it to function so I can install my 4 GB graphics card, which requires at least a 500w PSU.

Any help you can provide is appreciated, even if it's bad news. Thanks!

True enough. Still, I wonder what happened to my system originally--did the graphics card go out, or was it something else? I guess it's water under the bridge.

Thanks to everyone again for the assistance.

Thank you for the replies, folks.

My brother is unwilling to try my card(s) in his system, because he thinks it will FUBAR his own system, regardless of the fact it's only to test if they're detectable, no un/installation required. Without his permission, it's a no-go. I also checked my old system to see if I could try using the cards there, but it is woefully incompatible.

I seem to have discovered this, as well. I went to the HP website to see if there were any BIOS updates, and there was just one--released 5 months after the current BIOS version installed on my system. So, it seems like you're correct.

At this point, I think it could be anything.

I think I'm better off getting either an updated motherboard that will work along with my other components (and being more careful about what I buy), or just getting a whole new system.

Thanks for the replies.

I'm going to see if my brother will let me try both cards on his system. I'll get back to you. As for the motherboard, nothing appears scorched, burst, charred, damaged, etc. It looks like it always has--no visible damage.

I'm using the on-board graphics now, with the same monitor. No card is inserted into the PCI-E slot. Oddly, if I do put a card in, but start the computer with the on-board still enabled, I get the black screen, like it knows a new card is there but won't work with it.

Just over a week ago I was playing a game when my screen suddenly spazzed out. It turned into an image of vertical brown lines interspersed with a darker color line. The sound was skipping rapidly, as well. No keyboard commands worked, so I did the only thing I could—held the power button to shut it off.

When I restarted I received a black screen. The monitor was on and everything was the same as it was before, just no images on screen. The computer didn't act like it fully booted up, either. The fans were running, but as I said, no picture. The monitor's power button was flashing slowly, like it was in standby mode or asleep. I restarted several times (again, holding the power button) but it always restarted to the same result. I turned off the computer and monitor, unplugged the latter from the graphics card, and plugged it into the on-board VGA graphics. I started it up and got the same result, at first, but after then powering off and removing the graphics card, it booted up normally.

So I concluded, possibly incorrectly, that the problem was the graphics card itself. I cleaned and reapplied thermal grease to the heat sink in an attempt to solve the problem, but it didn't (it was a shot in the dark, anyway). So I ended up purchasing a new graphics card. After it arrived I immediately installed it, but I have run into the same problem—I plug everything in and up and when I power on the computer, I get a blank, black screen. As such, I can't go through the process of even trying to install drivers. I have disabled the on-board graphics through the Device Manager, but it didn't help. I've disconnected everything from the tower and removed the new card, then replaced everything, but there was no change.

After searching the Internet and wracking my brain over the possible problem, I can't determine if the motherboard's PCI-E slot has gone bad, or if the graphics card is defective, or if it's a problem with the BIOS, if the card is simply not compatible with my configuration, etc. Even though I can replace hardware and software and such, I'm not savvy enough with computers to determine such problems.

I do not have another computer system to plug the graphics card into and determine if that's the issue. I don't have an extra monitor to determine if that could be a problem, either.

Note: Everything about my computer is STOCK with the exception of the power supply, which was upgraded to a Corsair HX650W to be capable of supporting the older (dead?) graphics card. I bought the computer 5 years ago, so it's older than that (which may contribute to the problem).

This is the motherboard: https://support.hp.com/us-en/product/hp-pavilion-p7-1200-desktop-pc-series/5187022/model/5192622/document/c02980014

This is the new graphics card: https://www.newegg.com/Product/Product.aspx?Item=N82E16814202288 (most of this may as well be in Greek).

Another note: I'd noticed my computer running “harder”, the fans running more like maybe something was getting overheated, in the month or more prior to the old card going out. I'd opened the case and thoroughly blew out quite a bit of dust. I'm unsure if this has any bearing on the current problem at all, but I thought I'd mention it.

I admittedly did not do enough research or checking to see if the new hardware would be compatible with the old, as I know some things but not nearly enough. But if anybody with more knowledge than me can throw me a bone and help me figure out what exactly is going on, I would be very appreciative.

I'll toss my name in the hat as having the same issue as the OP. As far back as I can remember, Stacks have been buggy to the point of, well, pointlessness. Nothing ever wants to save or be changed due to some kind of error I don't understand. Never had this with the older system...*hint-wink-nudge*.

Freaking EXACTLY it, Zombie. It was exclusives and not just launch titles I should have been looking for. I need to work on my search engine skills.

Thank you very much for the time and effort you put into finding this, even if it was quick. It's appreciated.

I saw something recently somewhere on the Internet that I thought I had saved to my computer, but either didn't do so or forgot where I put it. In the event that I didn't save it (or did and don't find it), I was hoping maybe someone else had seen it or can at least point me in the right direction.

It was a chart (but not a spreadsheet) that showed three columns: one for PS4 launch titles, one for XBOX ONE launch titles, and a third for PC titles, which was substantially longer than the other two. The text was normal (like Times New Roman, etc.) and the background was plain white.

I don't know exactly where I saw it or how I got to viewing it. It may have been on GameSpot, or on RAPTR, or somewhere in Steam. I tried retracing my steps, checking my web history, searching links from my most frequently visited websites, but I haven't located it. If there is anyone who has seen something similar, or has any idea what it was I'm looking for, I'd appreciate it.
