MSI p55-gd55 - 8800GT Tags: Graphics Cards Computer Brother MSI Graphics Last response: March 9, 2010 2:34 PM in Graphics & Displays Share gl022331 March 9, 2010 12:19:57 AM Hi, I have just finished building a new computer: i5 750, MSI P55-GD55 and ... my brother's 8800GT When I start my computer, the screen stays completely black. I tried the gts250 of my brother in my computer and it worked. I tried 8800gt in my brother's computer and it worked. This means that the two video cards works... Why does the 8800GT doesn't work in my computer? Thanks (and sorry for my poor english...)

Your English grammar is better then a lot of other people who did speak it fluently and post here. m 0 l gl022331 March 9, 2010 1:16:14 AM Thanks for the reply, well it is now working... I've plug it in the other pci-express slot and it is now working... but still, isn't it weird that the gts250 was working in the same slot as the 8800gt wasn't??? m 0 l Related resources MSI P55-GD55 will not turn on, don't think it is PSU, Any Thoughts - Forum Msi 8800gt vs xfx 8800GT A Dog Edition - Forum MSI 8800GT strange vertical artifacts - Forum Msi gtx 670 2gb slower than my evga 8800gt 512mb - Forum MSI K9N ULTRA 2F doesn't work with palit 8800gt sonic - Forum Can't find your answer ?
