Startup screen BIOS hangs for 30 mins

Acer / Idea 510

Specs: Windows Vista
I'm having a startup problem with my PC for a while now. When I boot the PC, it will go into the BIOS screen but hangs there for half an hour with a 'broken' screen (see screenshot). Keyboard doesn't work during those 30 mins.

This is the screenshot, mention the characters are broken...

After about 30 minutes, the bios continues and Windows starts normally without any problems. All hardware and software is working fine as far as I can see.

I tried to locate the problem by removing and replacing hardware:
- Updated the BIOS version to the latest version succesfully
- Replaced memory
- Replaced HDD
- Removed CMOS battery and replaced (I had to reconfigure the BIOS, which I did when the 30 mins passed)
- Replaced the PSU

Anyway, I'm out of options! Anyone has faced this problem or can point me into a direction to solve it?

the hardware is an Acer Idea 510 (media center), 2GB RAM, running Windows Vista Premium 32 Bit.

Thanks in advance!

First, are you using onboard video or a video card ? Second, there may be some loose connections-I would check the main connection from the PSU to the motherboard, etc. Third, if loose connections are not the problem, disconnect everything but one stick of RAM, the cpu, and video. It could be the hard drive, for example.

the video card is onboard, but works well when the pc starts up after 30 mins. I rechecked all the connectors too. The problem occured suddenly a while ago.

I tried to solve it with only 1 RAM module and I also tried to use another one.. no result either.

Disconnecting all the other hardware didn't work as well. I disconnected the HD before. I did read something about boot information on the HD with Acer systems. Could that be something? I have doubts about that, because that wouldn't explained the 'broken' BIOS screen...

I could try to use a test HD instead of the old one to see if that helps. I'll let you know.

Try to disconnecting hdd,cd rom, any add in card, floopy drive. Leave cpu + heatsink,ram,psu tand start the system and go to bios and post back the result (some system won't work without floopy drive, if your system ask for floopy give it)

Try disconnecting all drives & see if it still freezes. Looking at the screenshot it looks like it stalls on the it the same place everytime? If it is, it would seem to be a memory problem. Remove the RAM & clean the contact edge. I usually use an eraser then wipe it with alcohol. Make sure it's 100% dry before reinstalling it & it wouldn't hurt to snap them in & out of the slot a few times to break up any oxidation in the slot. While you have the RAM out, see if there's a label on it with a make/model & the voltage specs. When you get it to fire back up, make sure the BIOS is setting up the RAM correctly...if it's not, do it manually. Also, since the T5500 is a 667MHz FSB CPU, the RAM should run at either 166MHz (DDR333) or 333MHz (DDR667).
