Strange Boot up Problem

By daveyboy82 ·
Hi guys,

My friend asked me 2 look at his computer, its got a strange problem. When booting the screen will go blank. I've tried safe mode, it loads all the drivers just fine then the screen just goes black and the restart button on the front of the comp doesnt work, nor does the power button so i haf 2 pull out the power cable.

I've replaced the power supply with a working 1. I tested the memory with memtest, and used the seagate diagnostic util to test the hard drive, both came up fine. Gfx card is okay. I've rest the CMOS.

When i did open it up it was caked in dust! A layer of it on the cpu heatsink. I managed 2 get most of it off. CPU temp seems normal.

Any suggestions? Hardware or software prob?

Hello

I had a simmilar problem with my PC.
I thought that my KVM switch box was playing up but it turned put to be a graphic card problem (And this is afterI hae reeplaced almost every single part of the PC including re-installing windows :)).
Might as well give it a try

Hi.

Okay I just tried another hard drive I had laying around n tried safe mode and it did the same thing, so that means its not a hard drive problem correct?

I would suspect a grafix problem but its got onboard gfx AND a AGP gfx card and i've tried both with the same result?

The comp works fine till u try n boot into windows then it just goes blank. If it was gfx wouldn't it b random?

Better to format the hardisk with proper bootable cd

Have you tried pulling the CMOS/BIOS Battery

by HAL 9000 Moderator In reply to Strange Boot up Problem

And replacing it with a new one that has a full 3 Volts. If the old one is flat the RTC isn't working and you'll hit a Logic Error when you start to load Windows as the files will be newer than the current Date/Time which isn't allowed.

Tried everything

by mjd420nova In reply to Strange Boot up Problem

Sounds like you've tried all possible cures and still no luck.. Try booting to the WIN CD and do the repair routine, it sounds like the wrong driver maybe getting loaded with a driver that the monitor is incapable of executing resulting in the blank screen.

Re: Tried everything

Hi mjd420nova,
you say that all you get is a black screen, but otherwise everything is working?. First do not do anything but replace another hdd inside your computer and try to install any os. If you still have trouble then your first port of call will be the bios, go into this and set the onboard grafics to "disable" and then switch off, put in a grafic card of your choice (a good one of course just to test) then bootup your computer, your memory chips seam ok otherwise your computer would not work but it would send out a beep or two to let you know. If you are having any more problems let me know on this post.
Peconet.

bad video card

by sgt_shultz In reply to Strange Boot up Problem

it sounds a hardware failure maybe. either the monitor, monitor cable or video card. can you take your monitor to another (working) computer to see if the problem follows the monitor? or purchase another video card to try.

Its not the monitor

by daveyboy82 In reply to bad video card

Im using a working monitor so its not that, or the power cable or monitor cable. FYI i did try using the 'repair' feature on the win xp cd, and it got all the way to the windows loading screen then just froze (but i was able to turn it off with the switch at the front this time).

It worked fine when i ran the memtest and hard drive test (the hard drive test alone took about half an hour).

Im really starting to think its a hardware problem, maybe a leaky capacitor? Orrr.. as i said earlier i did open it up to find a layer of dust on the cpu headsink. Might the CPU of overheated damaging it?

I took the CMOS battery out for 15 mins then tried with no success. But good point about it i'll try a different one today.

I hate blank screen problems!
