I just installed a brand new graphics card on my PC and formatted the main drive. My PC is this one: http://support.gateway.com/s/PC/R/1015229R/1015229Rnv.shtml The card is Sapphire's Radeon HD 4890 and I did upgrade to a 700w PSU just prior to install. Everything worked fine the first day but last night it slapped me with a BSOD and then it happened again this morning. Right before the BSOD, the screen gets all warped for a moment and then it goes BS. It went away too fast to read what it was but the event log shows the follwoing: Problem signature Problem Event Name: BlueScreen OS Version: 6.0.6000.2.0.0.768.3 Locale ID: 1033 Files that help describe the problem (some files may no longer be available) Mini121709-02.dmp sysdata.xml Version.txt Extra information about the problem BCCode: d1 BCP1: 00060200 BCP2: 00000002 BCP3: 00000000 BCP4: 8AB12C83 OS Version: 6_0_6000 Service Pack: 0_0 Product: 768_1 I suspect some driver issues but I can't figure out which one. The "files that can describe the problem" don't seem to exist. Any help would be GREATLY appreciated. By the way, one thing I noticed is that sometimes when I start windows, right before it asks me for the password, the screen gets warped for a second.
