Hi,

Really hope the specialists on this forum can help out.
4 weeks ago I was unable to boot my PC but from time to time I was able to boot and run normal.
After 2 weeks I brought the PC to a friend to let him have a look.
The PC was there for a week, no problems whatsoever; normal boot.
Only thing he did was a BIOS flash to the latest version.
PC was returned and yes the PC booted normally. Next day again no boot.
PC went to a repair shop. Again the PC booted normal. They did several benchmarks and the PC came out way above average with no errors. No hardware failures to be found.
PC came back home. Still the same problem; no boot.
I'm currently clueless on how to proceed next.
Any help would be highly appreciated.
