Hello everyone, today I expected a hard (or more than even one) issue(s) with my computer. Yesterday I installed Windows 7 Security updates and also with a driver clean installer newer GPU drivers. Somehow I recognized, that the system startup went a bit slower so I thought I make a restore of my system from yesterday (I made seperate point and also some hours later when Windows made the security updates, it made a restorepoint). After accepting the restore, the computer was working, then restartet (till yet normaly) but then when Windows logo should appear, a quick bluescreen appeared and the computer retarted again. Then I could chose normal start and quickstart with repairfuction. Normal start caused the bluescreen. In the second option the computer booted into something with a low resolution where I could chose to repair in cause of failures with a restorepoint. Here begins more trouble. Somehow my USB Mouse and USB Keyboard where inactive (no lights either). While on startup they worked, after the BIOS startup screen, where the light shorty goes out and then on again.. it didn't turn on again and in this way it didn't worked. I tried with another mouse. Same issue. Sadly I have just one other keyboard - a p2p one. I tried with it. And in may tried, most of it didn't work. Once I could make it, that in the windows where u say it should repair where u normaly chose the button with a mouse, I could tab there with ey p2p Keyboard and restore.. Of course it restored to the latest point. Then I thought, I try the restore point that is not from the windows security updates, but the one I made myself some hours before. This caused the exact same issue again and with some luck one time the p2p keyboard worked and now I am on this weird system. What I already tried: - tried to readout the bluescreen. problem: because they repair function used the latest working point, it is repairing into the system, where no bluescreen is logged and so there is no Minidump folder. (option for small dumpfiles is made already) - start into secure mode from windows 7. Same issue: bluescreen - tried cmd: sfc /scannow - no issues found - checked event manager: no warnings or error listed. There are just "information"s about event 1001 Windows Error Reporting with following content: Fehlerbucket 869137576, Typ 5 Ereignisname: StartupRepairOnline Antwort: Nicht verfügbar CAB-Datei-ID: 0 Problemsignatur: P1: 6.1.7600.16385 P2: 6.1.7600.16385 P3: ASUS P4: 25 P5: 1 P6: AutoFailover P7: 1 P8: NoRootCause P9: P10: Angefügte Dateien: Diese Dateien befinden sich möglicherweise hier: C:\ProgramData\Microsoft\Windows\WER\ReportArchive\Critical_6.1.7600.16385_53f7eb77ffe3d36c6b171085798df1b2f40dc8f_01e84a0a Analysesymbol: Es wird erneut nach einer Lösung gesucht: 0 Berichts-ID: d71f011c-e13d-11e5-a7f5-1c872c476cf8 I really don't know what it could be. Since they different keyboards and mice caused errors, I am sadly scared, that my pretty new (hafl year old) mainboard is broken. Someone knows what to do - Especialy u kemical?
