Hi all,
I took my laptop to Circuit City and showed it to one of their tech guys. We discussed the issue and it seems that this can not be video card problem since a bad video card will not show anything.
He suspect that most probable issue could be bad BIOS. I will post the answer in 2 days as to if this is the real issue or not.

It is very possible your bios got corrupted some how. The only way to fix this would be to get a new motherboard. Is your dell still under warrenty?

No the Dell is not under warrantly now ( I had 4 years of warrantly on this and problem occured after that
I am still waitng to hear from Circuit City guy but I got the impression that he can reset the BIOS .

Hmm after 2 days I go to Circuit City and got the answer that they were not able to flush the BIOS. Now they also suspect that video card is the problem. I asked them whats the guarantee and well there is none. I am very disappointed to say the least. I asked for my money refund ( $60) since they did absolutely nothing . To this I got the answer that they are responsible for running diagonistic . They ran diagonistic and did not find cause of problem. Well now I think I should have fought harder with them. Eeek . I feel as I have met few conmen who conned me .

Anyway I am back to where I started . Does anyone know how to flush BIOS in Dell 8100.

Also does anyone has any review for "www.impactcomputers.com". They contain a very large inventory of spare parts and I can ship them my laptop for $50.

The reason I dont suspect Video card is that if video card is faulty I should see nothing on the screen . My screen still shows odd color pattern all over.
Thanks for the inputs

I still think you just need a new motherboard.

I agree with you. This time I am biting the bullet and asked impactreview.com repair facility run diagonistic and told them that most probable cause is motherboard. Hmm I think I am looking at ~300 dollars of repairs if thats the cause. I will update what they find the cause which most probably is going to be motherboard.

Any updates on this issue?

I called the impactcomputer guys and they take 3-5 days to answer.I guess they will take all 5 days. I should be able to post the update on Friday ( June 9 )

PS: But as already posted our suspicions lie squarely on Motherboard.

new or semi new cards are sold on ebay.
when i remove my card or just twist it a little it works for a day or 2 then goes back to being messed up.
