Been asked to look at a pc....onboard vid us throwing up errors so tried adding a 5450 , it wouldn't post. Changed it for a gt210 and it post's but doesn't boot and sticks on nvram. Any ideas?
Sounds like a mobo failure, I came across a few of those ati p4 things and they did weird stuff like this. Id say just salvage what you can.
after trying with teh gt210 and no luck , finally did a full wipe and reinstall and its still failing video. time to share the bad news
