PC not booting correctly after installing new graphics card

To give you an idea of what I was doing, I was upgrading my power supply and graphics card. Installed them both. I connected my monitor to my PC via DVI. Then when I booted it up, the monitor wasn't receiving a signal. Nor was my keyboard (tried pressing caps lock and light wasn't going on). So my friend said I might have to take out the new graphics card, boot up the PC, and disable the integrated graphics card. However, when I put everything back together the way it was (including with the original power supply) it did the same thing. No signal to monitor or keyboard. The PC is not being fully booted correctly. It powers on and everything, but something is wrong. Could you guys help! I hope I didn't screw up my motherboard!

PS: I have an Asus m32cd

Clarification Request
Need information on that graphics card

and your PS. As well, though you said no signal to your monitor, did you get any BIOS screens? Any beeps? That your keyboard didn't initialize might offer a clue. Is is a USB or PS2 type keyboard? It could sound as if your PC didn't even POST. Try the new PS with the integrated graphics. If it's OK, add the new graphics card. If your new graphics card has its own power connector, make sure to plug that in. Also, examine the plug for incorrectly seated pins.

I got no BIOS screens. It said "no signal detected" when selecting the correct input from the monitor, as if the PC wasn't on. However the PC is turning on, just not booting correctly I believe. My keyboard is connected via USB, so is my mouse. My monitor is currently connected via HDMI. I tried last night using the new PSU with the integrated graphics and the same thing happens. I don't think its the PSU because it was working fine just yesterday before I started doing all this. I think its either something that happened with the mobo or something not connected correcty

In your top post

You said the computer is connected via DVI and now you have it connected via HDMI cable.
What happens if you use the DVI again ?

Just wondering if there's a bad cable in the mix

- Collapse -

Looks like the mobo has hdmi and vga only.

- Collapse -

That's why I am using HDMI. I was using DVI with the new video card installed because it only had DVI and mini hdmi ports. I don't have a mini hdmi cable

This still smells like a bad cable to me

I would swap cables for peace of mind.
I would also try some Linux Live Disk for the halibut.

The cables were fine yesterday. They're almost brand new. But I did just hook up a VGA to my monitor, and the same thing happened.

It's beginning to sound as though your idea of MB

damage could be correct. If you put all the original parts back in, cleared the CMOS, and still had the same failure, something may have broken. What I'd do is check the PS output voltages with a DVM which can be a trick with a motherboard issue. But generally, if your fans work and HDs spin, your 12v has been generated. You need a DVM and will need to google something like "computer power supply pinouts" to determine where you can measure for the proper voltages. If a needed voltage is missing, you'd need to disconnect the MB plug and try again. This gets tricky as some load is needed. You also need to know how to force the PS to turn on using the green wire to ground jumper trick. If you can verify the PS isn't bad, you're left with the MB or something else connected to it. I'd say that inserting a new graphics card and PS plug could possibly flex the board and break something such as a printed circuit land or solder connection. Today's lead free solder is quite unforgiving in that respect.

I'm probably going to have a 2nd set of eyes look at it to verify there isn't something stupid that isn't hooked up right.

I was thinkin' the same thing

But hated to say it .
I would still try to boot up some Live OS though.
You know how hard headed I can be Shocked

Hard headed?

I thought in your career you were hard "hatted". Maybe you didn't really need one. Happy

Starting to think

that i screwed up here. Someone on another forum asked if I used an anti static wrist band, which i didn't. So I don't if that screwed up the motherboard in any way. Ughh.

Anti static wrist band isn't imperative

but good practices to prevent static discharge are important. Simple things like picking up sensitive parts by the edges and grabbing the PC chassis before installing or removing components do offer some protection. Lay your parts on the anti-static bags they came in and never on metal surfaces even with the bags between them. Some will use special grounded mats as well. I had one when working out in the field but rarely felt a need for it. What you might try if you've not done so already is to gut the chassis and try to assemble the PC components on a wooden table Use the minimum to attempt a boot. You don't even need RAM for that. You should get beep codes with none installed but all you're really looking for initially is an attempt to POST. If you get fans that run continuously then you have 12v. If you can measure the 5 and 3 volt positions and they're within limits, your PS is probably OK. If still no POST or beep codes, it's down to your CPU and MB. The MB is too full of stuff to even begin to isolate the failure so that's where it would end, I'm sorry to say. If your CPU is still good and you can find a MB that will work with it, you can be back in business for under 100 bucks easily. But if your mind is to game, you're probably better off starting fresh with all the latest. Good luck.

Thanks so much

for your long and thorough post. I really appreciate the help. I'm bringing it to my friend's house to attempt to troubleshoot, and probably eventually, to replace the motherboard. It just sucks since the computer is brand new and i just got it recently. I was given a free video card and PSU from my friend, so I figured why not install it. Even though the ASUS M32CD is not a "gaming" computer, I was starting to game casually on it (Counter-Strike). It handled it pretty well, with the exception of a few games that I had to run on low quality. The processor is fine, so I figured by just installing a graphics card and a 500W PSU I would do the trick and I'd save myself a few hundred bucks. All my "high-end, high quality" games I use my Xbox One for. But basically, it's mainly for home and office use.

Integrated Graphics

IGP. I currently took out the new graphics card I was trying to install (EVGA GTX 550 Ti) and the new power supply (Corsair CX500) and connected everything back the way it was. ATX 24-pin on the motherboard, the 4-pin connector for the CPU, and the SATA cable for the HD. The processor fan is running, so is the PSU fan (btw the stock PSU is a 350W). All of the sudden, I just can't get a signal to my monitor/mouse/keyboard. I also tried removing the battery on the motherboard to try and reset BIOS. I put it back in and the same thing happened. I just don't understand what could have happened

Make it smaller

Psu+mobo+cpu/hsf+one stick of ram+monitor.

No usb.

- Collapse -

Tried and still nothing. I believe I do hear a beep which should mean that it passed POST, no?

- Collapse -
Make it smaller

No ram.
If you have a case monitor.
If your monitor has the speaker leave it plugged in.

Power up.
It should squall.

Removed RAM

Removed RAM and still not visual monitor. My speakers are hooked up to monitor. I honestly don't know what could have happened. It's like a mystery.

(NT) Did it Beep ?
