View Full Version : POST/BIOS screen looks corrupted, sometimes. Also missing hard drive.

So, I got a new case today, and spent all day moving all my hardware from one case to another, clearing dust in the process using a vaccum cleaner - possible mistake.

When I'd finally finished and booted up the computer, the screen was covered in lines and blocks of white, though it responded to keyboard commands and went to attempting to launch Grub - the bootloader. When it tried to launch it, though, the relevant hard drive wasn't detected and it rebooted itself, presenting me with another corrupt boot screen.

Disconnecting the power supply from one of my hard drives seemed to do the trick for the corrupt boot screen. For one boot. When I rebooted next, trying to fix the hard drive detection, the corrupt screen returned and I was back to square one.

I've fiddled about with cables and checked connections, as well as checking that both of my boot hard drives actually work - they do. This leaves me at the conclusion that it is a hardware failure that happened during the move. I'm not sure what has failed, though. It may be the motherboard, since there are two seemingly unrelated problems, or it may be that both the Graphics card and IDE cable that connects the two boot drives has failed.

Frustrating, since I'm not especially willing to spend more money on testing the card and cables.

Some background info/specs:

Two Maxtor 40GB IDE hard drives - had these since I first built the computer. One has Linux on, one has Windows. Both are connected by the same IDE cable. Both worked before the move.

One Samsung Spinpoint SATA 500GB hard drive - Being detected fine, used for data storage. Worked before the move.

One Samsung Spinpoint F1 SATA 1TB hard drive - Only got it today; nothing on it, but it was the hard drive I first disconnected from the PSU.

ATI X1800XL PCI-Express graphics card, 256MB - Worked before the move.

ECS NFORCE4M-A Motherboard - Never heard of the brand before, but it worked before the move.

1GB Patriot RAM - Worked before the move, not really related to the problem as far as I can see.

AMD 5200+ Processor - Worked before the move. Was not removed from its slot during the move, and was not touched.

Old CD writer.

Corsair HX520 PSU - Worked before the move. Certainly works after the move, but can it take the specs above?

Did you anti-static yourself before touching the PC parts?

Btw if you want to reset the BIOS settings (incase somehow that messed up) take out the round battery.

You can do what limited said and if that doesnt work there should be 2 sets of jumpers on the board. Look in your mother board book for details to find out where it is.

1.) Turn off pc
2.) Swap jumpers
3.) Leave in there for about 30secs (most books say 10secs but safe just go 30secs)
4.) swap back and it should reset the bios.


Alright to add on what else you can do.
I would eliminate causes so disconnect hardware to determine.

Example: Back in the day when I had a Dell. I had to replace the hard drive. I didnt use it for a few day for some reason and had Dailup cable hooked to it and left her on. Well lightning storm came and it would not boot. I thought everything was fried. Well I disconnected hardware. Found out it was the modem.

Thanks guys, thought of the BIOS reset while I slept, so I'll try that now.

Fake Edit: Bios reset appears to have fixed the ugly boot screen, but I'm still stuck with one missing hard drive. Will boot Live CD of Ubuntu to see if I can find anything.

Second Edit: Ubuntu live CD won't load. Tried motherboard boot disk, but BIOS protection is on so it can't reset it. Also the BIOS protection jumper is soldered :/

Third Edit: BIOS reset has not fixed the boot screen problem; it was only temporarily booting normally. Loaded failsafe defaults and Ubuntu seems happy enough loading from the CD. Will check Hard Drive when it's all loaded.

Update: Well, my Ubuntu installation data is intact, as well as my precious data, but Grub still refuses to boot it. Will fiddle about with reinstalling Grub from the terminal.

Probably final update: Motherboard is borked. Graphics card has a corrupt memory chip. Awesome.
