So for some reason my onboard Radeon HD 7660D just dropped from over 80 MH/s down to 20. I can't figure out why and I can't get it to go back up. I just reinstalled the drivers, nothing. Temp would sit at 65-70 C with spikes to 75 Csometimes, now 30-35 C even when mining. I'm using GUIMiner v2012-12-03; mobo is Gigabyte GA-F2A55M-HD2 with AMD A10-5800K APU, 650W PSU, 16GB RAM on Win7 64.
What can I check? What would cause me to lose 75% of my hashing power?
