Pc wont boot

[DeanX]

Guys im pulling my hair out here my pc wont boot up. Checked all wires and connectors. The power light on the motherboard lights up but thats all. Help please

What do you mean? for example is it:
not starting at all
going into the bios screen and not recognizing your harddrive
Starting but not booting windows
etc.

The topic may have more exposure here.

It wont switch on at all

Check all connections, unplug and reconnect all internal wiring. If still nothing, remove all the components and just try to boot the mobo and CPU. If still nothing I'd say your psu may have gone wallop.

that happened to me before. then I just removed the mobo from the case and put it back in there again and it worked. didn't even remove or touch any of the wires or components.

Im gonna rebuild it all when ive got time hopefully itll work but if not ill buy a new cpu

[raptor2009]

This has happened to me before and was solved in my case by removing the battery off the board which resets the bio's, and hey presto it worked, it might not for you though but it's worth a shot.

What kind of harddrives do you have? Is it a RAID-config?
I suppose you checked BIOS for boot priority..
Check the power connectors on the MB once again..
the small ones

[DeanX]

Checked the wires numerous times everything seems fine. i was never confident with resettin the batter on motherboards and plus im not sure how its done properly

[Kaelan002]

You just pull the battery out, wait a few seconds and stick it back in

[DeanX]

Yeah i did it now. Still not working. I reset cmos too. Im starting to think the psu as died. When got bit of spare cash ill have to buy one and pray it fixes it. I cant really afford a new build

[Kaelan002]

Maybe the battery has run out, how old is the motherboard?

[DeanX]

Maybe 2 years deffo no more than two and half. Im runnin a 550w psu which is like 6 years ish old.

Maybe the battery has run out, how old is the motherboard?

It still should boot, it won't store the BIOS settings anymore etc. but as I understood it the machine doesn't do anything when he tries to turn it on.

As suggested before, you should try to boot it with the minimal (MoBo, CPU and RAM) and see if anything happens (maybe a light goes on or a fan starts spinning at least).
If nothing happens it is most likely either the PSU or the motherboard (would be nice if you could test the PSU in another machine).

Aria have got 750w for 25 quid, will buy that and see if it boots up cant really afford anything dearer

[DeanX]

Well with a stroke of luck ive just recieved a tax rebate. Can anyone suggest a 750w psu? Decent price still tho

[G3!ST]

why do u need 750w?!

System Specs ?

Mobo, Gfx card, HDD, CDROM, Mem

Initial step in any test is to minimize your hardware set up.

Unplug all drives, The fault could lay with any of these, and put a load on the 12V lines, that stop the PC booting.

Has the mobo got a gfx chip set of its own, separate to the gfx card. Many do, which is ideal for testing purposes, since it allows the gfx card to be removed.

remove any other hardware attached to the machine, apart from the keyboard.

Is the PC speaker connected, or as in some cases there isn't one, then find an old PC speaker and connect to the mobo.

Post code beeps can help immensely when trying to determine a fault

After you minimize, you need to make sure all PSU connectors are inserted correctly.

Switch on and watch the CPU fan and describe what it does and listen to the POST beeps

I get no post nothing boots. I tried without gfx and ram
Inserted.

Anyways specs are. Mobi asus p5q-e. gfx hd4870. Cpu q8800. 2gb ram. 250gb sata hdd and basic 52x dvdrw
