PC Won't boot properly! (Need help !)

Well I HAD some problems when I first got Robs old computer about getting it to startup, but I quickly found out that the problem was that I was using incompatible RAM and replaced the RAM that I took out and everything works fine now. Until today...

I did nothing different, I just went to turn it on and the monitor said "No signal" also when it initially boots there is not a second *Beep* sound. I have tried 4 other monitors and it is not the monitor that is causing this.

A list of things I have already tried

-Remove the GPU and boot without it (No change)

-Remove RAM sticks 1 by 1 and attempt to boot (No luck)

-Change the slots that each RAM card is in (Ram card #1 goes to the slot where RAM card #2 was) I had no luck either.

-Unplug and try another HDD (no change)

-Check to make sure that all cords and wires are plugged in firmly and there is no loose wire. (No luck)

THE PC STARTS AND BOTH FANS TURN ON JUST FINE, AND THE LIGHTS ON THE PC LIGHT UP JUST FINE

I am not afraid to remove anything and know a little so I can try pretty much everything to get this fixed.

I can take a video of the PC starting up and put it on here.

I hope that this is not the MOBO dying...

Can u reset the BIOS?

 

Newer boards usually have a reset button, older ones have a jumper that you need to change.

If its really old, it may need a new CMOS battery.

The GPU worked with the Mobo before and I downloaded all the driver updates..

And Cereal, there is no signal to the monitor so I cannot go to the BIOS

And the Mobo is from 2009 so, I don't know, I can supply you all with a video and a few pics later

Does the mobo have integrated graphics? If so then strip out everything except the mobo, cpu and a stick of ram and try booting from a linux livedisk (https://help.ubuntu.com/community/Lubuntu/GetLubuntu Lubuntu is a fairly lightweight distro) to check that everything works correctly. Then start adding components back in one-by-one until it stops working.

 

A video of the pc starting up would be quite useful (showing both the box and the monitor)

Reinstallation of Windows is needed. Your drivers fucked it up. Had this problem.

 

After this, make sure you be VERY CAREFUL which and what drivers you install.

Lundy I don't think you understand, the computer is starting just fine, There's no signal for the monitor at all. I've already tried booting from a different drive and the same thing happened.

You got a splash screen, then a no signal. 

Have you tried "safe mode"? 

Do you have the windows disk?  If so boot from it.

Could it be bad hdd? Try to get another hdd, install windows on it. Or like other ppl said. Go to bios and restore to default.

 

I say bad hdd because I know some computers i've worked on did similar start up. Power Button > Splash screen > Blank screen or Power Button > Splash screen > Hardware progress screen startup or Power Button > Splash Screen > Stuck on Splash screenGL!

No idea why, but it is....

 

I have it in my basement which is Cement floors and not really insulated, and outside it's like -20 Air temp, I would say it's probably 40-50 degrees in my basement, do you think the cold is affecting it? Because I brought it upstairs to work on and tried turning it on before I worked on it and it booted. It sat for about 4 hours in like 70 degrees so Idk...

What I tried to say was I have it in my really cold basement, and then when I brought it upstairs and let it sit for a few hours it warmed up and suddenly worked... coincidence?

Don't put the computer on the cold floor!  The floor is colder than room temp.  Put it on 2x4's to elevate it!  All the components should operate within it's thermal range.  Also cement represents "ground" and who knows how it might have affected it.

Cold makes metal contract, so there may be a loose connection. Maybe a hairline crack in the circuitry on the board. Or maybe one of the screws holding the board to the case isnt connecting all the way, (make sure they are all tight, they ground the board to the case.)

 

Glad its working, maybe it was just scared to be all alone in the basement.

 

In the picture, on the edge of the board, there is a lil blue rectangle that sits on 2 pins. Under it I think it says "clear cmos" u move that lil blue thing so it connects the middle pin and the one its not normally connected to, and that will reset your BIOS, if it gets corrupt.

You can do this without booting the computer up.

 

Just move it over, then move it back, and try to boot, if it happens again. (Check your manual to be sure, but thats what it looks like to me from the picture.)

Its a fail safe, in case you try to overclock too high and PC wont boot.

Thanks!

 

I have a few blankets under it and it propped up on some wood boards now!

 

Yesterday I got home and it wouldn't boot again so I brought it upstairs and set it by the vent for 20 minutes and then it booted

lol.  You probably  have  a connection issue with your monitor or graphics card, or in between.  PC's will operate just fine down in cold weather. You have to get it down to like -40c before you will get any kind of component trouble. CPU's like the cold they actually work better the colder they are.  And when I say colder Im talking you can opperate a CPU down to like -100c (were talking liquid nitrogen cold yo). Your AGP slots on the other hand can be temperamental. Specially if this is an older pc that has been moved around a lot or has had its boards plug'd in and out often. The fact that this PC came was shipped from Rob up in the Great White North, keeping in mind that it probably went from room temperature to below freezing in a shipping van some ware and back to room temp again,,,, Well Circuit connectors are made of soft metal like Copper, Plated TIN, Platinum or Gold. All of witch react quite quickly with temperature variations. This Tends to wick or loosen the connections over time, And if any moisture has been allowed to come into contact with these surfaces it will create corrosion witch even further hinders conductivity. 

 

I would be a good idea to check all connections, Boards, pins, cables.  Lightly push down on all roms to make sure they are fully inserted into there sockets.

 

The fact that you get a flash screen and then No Signal tells me that most likely you have a driver incompatibility.  Check your display you are using and download a generic VGA driver that supports your monitor. You can install it with a driver boot disk that you can download from many places on the internet. Assuming you have access to another pc. Another common problem is the wire or plugs in either the monitor or pc. HDMI cables are are very delicate and often go out with lots of plugging in and out or twisting of the cables. They can work fine with a little load on them. and then fail when you pc starts to push full graphics signals to your monitor.

 

A good idea is to clean your AGP, PCI and DIMM sockets. This can be done with a Alcohol wipe like you find in a first aid box. and a piece of card stock or a credit card (just make sure you don't use the side the magnetic strip is on). Simply fold the wipe over the card and wipe it back and forth a few time in the slot. Be careful not to use to much force or a card that is thicker then the contacts of the circuit board.  And always before you do any kind of work inside your pc. you MUST GROUND YOURSELF OUT. Best way is to simply work on a rubber mat or smooth floor like in the kitchen. Before you touch any components always Run you hand over the unpainted metal of the Case. If possible keep the metal case in contact with your skin. Always handle PCB's Proms and Simms from the edges. Avoid touching the solder or connector pins. 

 

Hope this helps.
